Postbariatric surgery hypoglycemia: Nutritional, pharmacological and surgical perspectives.

Post-bariatric hypoglycaemia (PBH) is a metabolic complication of bariatric surgery (BS), consisting of low post-prandial glucose levels in patients having undergone bariatric procedures. While BS is currently the most effective and relatively safe treatment for obesity and its complications, the development of PBH can significantly impact patients' quality of life and mental health. The diagnosis of PBH is still challenging, considering the lack of definitive and reliable diagnostic tools, and the fact that this condition is frequently asymptomatic. However, PBH's prevalence is alarming, involving up to 88% of the post-bariatric population, depending on the diagnostic tool, and this may be underestimated. Given the prevalence of obesity soaring, and an increasing number of bariatric procedures being performed, it is crucial that physicians are skilled to diagnose PBH and promptly treat patients suffering from it. While the milestone of managing this condition is nutritional therapy, growing evidence suggests that old and new pharmacological approaches may be adopted as adjunct therapies for managing this complex condition.

Female infertility in the era of obesity: The clash of two pandemics or inevitable consequence?

Obesity is an epidemic that has led to a rise in the incidence of many comorbidities: among others, reduced fertility is often under-evaluated in clinical practice. The mechanisms underlying the link between reduced fertility and obesity are numerous, with insulin resistance, hyperglycaemia and the frequent coexistence of polycystic ovary syndrome being the most acknowledged. However, several other factors concur, such as gut microbiome alterations, low-grade chronic inflammation and oxidative stress. Not only do women with obesity take longer to conceive, but in vitro fertilization (IVF) is also less likely to succeed. We herein provide an updated state-of-the-art regarding the molecular bases of what we could define as dysmetabolic infertility, focusing on the clinical aspects, as well as possible treatment.

Could very low-calorie ketogenic diets turn off low grade inflammation in obesity? Emerging evidence.

Obesity is an emerging non-communicable disease associated with chronic low-grade inflammation and oxidative stress, compounded by the development of many obesity-related diseases, such as cardiovascular disease, type 2 diabetes mellitus, and a range of cancers. Originally developed for the treatment of epilepsy in drug non-responder children, the ketogenic diet (KD) is being increasingly used in the treatment of many diseases, including obesity and obesity-related conditions. The KD is a dietary pattern characterized by high fat intake, moderate to low protein consumption, and very low carbohydrate intake (<50 g) that has proved to be an effective and weight-loss tool. In addition, it also appears to be a dietary intervention capable of improving the inflammatory state and oxidative stress in individuals with obesity by means of several mechanisms. The main activity of the KD has been linked to improving mitochondrial function and decreasing oxidative stress. ß-hydroxybutyrate, the most studied ketone body, has been shown to reduce the production of reactive oxygen species, improving mitochondrial respiration. In addition, KDs exert anti-inflammatory activity through several mechanisms, e.g., by inhibiting activation of the nuclear factor kappa-light-chain-enhancer of activated B cells, and the inflammatory nucleotide-binding, leucine-rich-containing family, pyrin domain-containing-3, and inhibiting histone deacetylases. Given the rising interest in the topic, this review looks at the underlying anti-inflammatory and antioxidant mechanisms of KDs and their possible recruitment in the treatment of obesity and obesity-related disorders.

Genome Editing and Obesity.

Defined as a condition of body fat excess leading to significant morbidity, obesity is a chronic metabolic illness associated with a significant number of diseases. The incidence of obesity does not solely depend on dietary habits, with energy balance being regulated by the complex interactions between genetic, behavioural and environmental factors. Genome-wide association studies (GWASs) have demonstrated that several genes are linked to obesity, and these findings shed light on a growing number of novel potential therapeutics for weight management, including genome editing. In this regard, the cutting-edge technology known as clustered regularly interspaced palindromic repeats (CRISPR)/CRISPR-associated protein (Cas), thanks to its ability to edit DNA or modulate gene expression in eukaryotic cells, undoubtedly enables to understand the genetic mechanisms implicated in obesity and could be a promising tool for its treatment. This chapter summarizes the genetics underlying obesity and currently available obesity treatments, further discussing the research progress of genome editing in the knowledge and treatment of body fat excess.

Central obesity, smoking habit, and hypertension are associated with lower antibody titres in response to COVID-19 mRNA vaccine.

AIMS: To explore variables associated with the serological response following COVID-19 mRNA vaccine. METHODS: Eighty-six healthcare workers adhering to the vaccination campaign against COVID-19 were enrolled in January-February 2021. All subjects underwent two COVID-19 mRNA vaccine inoculations (Pfizer/BioNTech) separated by 3 weeks. Blood samples were collected before the 1st and 1-4 weeks after the second inoculation. Clinical history, demographics, and vaccine side effects were recorded. Baseline anthropometric parameters were measured, and body composition was performed through dual-energy-X-ray absorptiometry. RESULTS: Higher waist circumference was associated with lower antibody (Ab) titres (R = -0.324, p = 0.004); smokers had lower levels compared to non-smokers [1099 (1350) vs. 1921 (1375), p = 0.007], as well as hypertensive versus normotensive [650 ± 1192 vs. 1911 (1364), p = 0.001] and dyslipideamic compared to those with normal serum lipids [534 (972) vs 1872 (1406), p = 0.005]. Multivariate analysis showed that higher waist circumference, smoking, hypertension, and longer time elapsed since second vaccine inoculation were associated with lower Ab titres, independent of BMI, age. and gender. CONCLUSIONS: Central obesity, hypertension, and smoking are associated with lower Ab titres following COVID-19 vaccination. Although it is currently impossible to determine whether lower SARS-CoV-2 Abs lead to higher likelihood of developing COVID-19, it is well-established that neutralizing antibodies correlate with protection against several viruses including SARS-CoV-2. Our findings, therefore, call for a vigilant approach, as subjects with central obesity, hypertension, and smoking could benefit from earlier vaccine boosters or different vaccine schedules.

An extra virgin olive oil-enriched chocolate spread positively modulates insulin-resistance markers compared with a palm oil-enriched one in healthy young adults: A double-blind, cross-over, randomised controlled trial.

AIMS: To investigate if extra virgin olive oil (EVOO) or palm oil enriched chocolate spreads consumption leads to different results in terms of plasma ceramides concentration, glucose and lipid metabolism, inflammatory markers and appetite regulation in young healthy subjects. METHODS: In a 2-week, double-blind, cross-over, randomised controlled trial, 20 healthy, normal-weight subjects with a mean age of 24.2 years (SD: 1.2), consumed chocolate spread snacks (73% of energy [%E] from fat, 20% from carbohydrates and 7% from proteins), providing 570 Kcal/day added to an isocaloric diet. The chocolate spreads were identical, except for the type of fat: EVOO oil, rich in monounsaturated fatty acids (MUFAs), or palm oil, rich in Saturated Fatty Acids (SFAs). RESULTS: EVOO-enriched chocolate spread consumption led to better circulating sphingolipids and glucose profile, with reduced plasma ceramide C16:0, ceramide C16:0/ceramide C22:0-ceramide C24:0 ratio and sphingomyelin C18:0 (P = 0.030, P= 0.032 and P = 0.042, respectively) compared to the palm oil-enriched chocolate spread diet. HOMA-IR and plasma insulin were lower, while the Quicki and the McAuley Index were higher after the EVOO diet compared to the palm oil diet (P = 0.046, P = 0.045, P = 0.018 and P = 0.039 respectively). Subjects maintained a stable weight throughout the study. No major significant changes in total cholesterol, triglycerides, HDL, inflammatory markers, and appetite-regulating hormones/visual analogue scale were observed between the groups. CONCLUSIONS: Partially replacing SFAs with MUFAs in a chocolate-based snack as part of a short-term isocaloric diet in healthy individuals may limit SFAs detrimental effects on insulin sensitivity and decrease circulating harmful sphingolipids in young adults.

Beyond weight loss in nonalcoholic fatty liver disease: the role of carbohydrate restriction.

PURPOSE OF REVIEW: The low fat diet (LFD) is currently the first choice to treat nonalcoholic fatty liver disease (NAFLD) alongside with physical activity. However, low carbohydrate diets (LCDs) and ketogenic diets have gained attention lately, thanks to their favourable impact in reducing intrahepatic triglyceride content. We therefore aimed at providing an update on recent evidence evaluating the hepatoprotective effects of such dietary interventions. RECENT FINDINGS: Novel findings confirmed previous evidence by showing beneficial effects on liver fat content reduction for both LFDs and LCDs. The further restriction of carbohydrates to less than 50 g/day, usually leading to ketosis, confirmed to produce an improvement in NAFLD, with very low-calorie ketogenic diets possibly proving particularly beneficial thanks to the significant weight loss that can be obtained. SUMMARY: Most of the latest evidence shows that carbohydrate restriction plays a fundamental role in the modulation of lipid metabolism leading to similar efficacy in improving NAFLD compared with LFDs. The hepatoprotective role of carbohydrate restriction appears to be boosted when ketogenesis is induced, when the total calorie intake is extremely reduced, or, possibly, when dietary interventions have reduced content in free sugars, making such interventions valuable tools to deal with NAFLD.

The Mediterranean diet increases glucagon-like peptide 1 and oxyntomodulin compared with a vegetarian diet in patients with type 2 diabetes: A randomized controlled cross-over trial.

AIM: To compare a Mediterranean diet (MED) with a high-fibre vegetarian diet (HFV) in terms of hunger-satiety perception through post-prandial assessment of appetite-related hormones glucagon-like peptide 1 (GLP-1) and oxyntomodulin, as well as self-rated visual analogue scale (VAS) quantification, in overweight/obese subjects with type 2 diabetes (T2D). MATERIALS AND METHODS: Twelve T2D subjects (Male to female ratio = 7:5), mean age 63 ± 8.5 years, were enrolled in a randomized, controlled, crossover study. Participants consumed an MED meal as well as an isocaloric meal rich in complex carbohydrate as well as an isocaloric MED meal in two different visits with a 1-week washout period between the two visits. Appetite ratings, glucose/insulin, and gastrointestinal hormone concentrations were measured at fasting and every 30' until 210' following meal consumption. RESULTS: GLP-1 and oxyntomodulin levels were significantly higher following MED meal compared with HFV meals (210' area under the curve, p < 0.022 and p < 0.023, respectively). Both MED and HFV meal resulted in a biphasic pattern of GLP-1 and oxyntomodulin, although MED meal was related to a delayed, significantly higher second GLP-1 peak at 150' compared with that of HFV meal (p < 0.05). MED meal was related to lower glucose profile compared with HFV meal (p < 0.039), whereas we did not observe significant changes in terms of self-reported VAS scores and insulin trend. CONCLUSIONS: In T2D overweight/obese subjects, an MED meal is more effective than a HFV meal in terms of post-prandial plasma glucose homoeostasis and GLP-1 and oxyntomodulin release. These changes were not confirmed by VAS appetite self-assessment over a 210' period.

Liver disease in obesity and underweight: the two sides of the coin. A narrative review.

PURPOSE: Malnutrition, whether characterized by not enough or too much nutrient intake, is detrimental to the liver. We herein provide a narrative literature revision relative to hepatic disease occurrence in over or undernourished subjects, to shed light on the paradox where both sides of malnutrition lead to similar liver dysfunction and fat accumulation. METHODS: Medline, EMBASE, and Cochrane Library were searched for publications up to July 2020. Articles discussing the association between both chronic and acute liver pathology and malnutrition were evaluated together with studies reporting the dietary intake in subjects affected by malnutrition. RESULTS: The association between overnutrition and non-alcoholic fatty liver disease (NAFLD) is well recognized, as the beneficial effects of calorie restriction and very low carbohydrate diets. Conversely, the link between undernutrition and liver injury is more complex and less understood. In developing countries, early exposure to nutrient deficiency leads to marasmus and kwashiorkor, accompanied by fatty liver, whereas in developed countries anorexia nervosa is a more common form of undernutrition, associated with liver injury. Weight gain in undernutrition is associated with liver function improvement, whereas no study on the impact of macronutrient distribution is available. We hypothesized a role for very low carbohydrate diets in the management of undernutrition derived liver pathology, in addition to the established one in overnutrition-related NAFLD. CONCLUSIONS: Further studies are warranted to update the knowledge regarding undernutrition-related liver disease, and a specific interest should be paid to macronutrient distribution both in the context of refeeding and relative to its role in the development of hepatic complications of anorexia nervosa.

The gastro-jejunal anastomosis site influences dumping syndrome and weight regain in patients with obesity undergoing Laparoscopic Roux-en-Y Gastric Bypass.

PURPOSE: The Laparoscopic Roux-en-Y Gastric Bypass (LRYGB) is an effective weight loss procedure. The gastro-jejunal (GJ) anastomosis required can be performed on the anterior or posterior gastric pouch wall. No studies have compared these variants in terms of efficacy and onset of dumping syndrome (DS) and weight regain (WR). We aimed at assessing the prevalence of DS in relation to the site of anastomosis together with identifying prognostic factors of DS and WR. METHODS: Patients who had undergone LRYGB with anterior (AGJ) or posterior (PGJ) anastomosis in 2010-2019 were retrospectively analyzed. We collected demographic data, medical history and the prevalence of DS evaluated through the Sigstad Score, together with WR data. RESULTS: 213 patients were enrolled, of which 51.6% had an AGJ and 48.4% had a PGJ. The mean follow-up time was 81 ± 18 and 27 ± 13 months in the AGJ and PGJ group, respectively (p < 0.0001). Excess weight loss was 77.59% and 94.13% in patients with AGJ and PGJ, respectively (p < 0.001). WR rate was 16% and 4% in the AGJ and PGJ population, respectively (p < 0.001). DS prevalence was 38% and 76% in the AGJ and the PGJ population, respectively (p < 0.0001). The site of anastomosis was identified as an independent predictor of DS (OR5.15; 95% CI 2.82-9.41; p < 0.0001) and WR (OR5.31; 95% CI 2.32-12.15; p < 0.0001). Obesity-related complications significantly improved after surgery independent of the anastomosis site. CONCLUSION: LRYGB is effective in determining long-term weight loss and improvement of complications. AGJ is associated with lower prevalence of DS but more frequent WR. The anastomosis site is a factor to be considered when performing LRYGB. LEVEL OF EVIDENCE: Level V, cross-sectional descriptive study.

Obesity treatment within the Italian national healthcare system tertiary care centers: what can we learn?

INTRODUCTION: The prevalence of obesity is soaring all over the world, and Italy is reaching the same pace. Similar to other countries, the Italian healthcare system counts on a three-tier model for obesity care, and each region has freedom in the implementation of guidelines. No national record is currently available to monitor the actual situation throughout the country. PURPOSE: To provide a report of the current status on the availability of specialized public obesity care services in Italy. METHODS: Regional prevalence of obesity was extrapolated from publicly available data. Data on facilities for the management of obesity were retrieved from records provided by national scientific societies. Whenever possible, data was verified through online research and direct contact. RESULTS: We report a north-south and east-west gradient regarding the presence of obesity focused facilities, with an inverse correlation with the regional prevalence of obesity (R = 0.25, p = 0.03). Medical-oriented centers appear homogeneous in the multidisciplinary approach, the presence of a bariatric surgery division, the availability of support materials and groups, with no major difference on follow-up frequency. Surgery-oriented centers have a more capillary territorial distribution than the medically oriented, but not enough data was retrieved to provide a thorough description of their characteristics. CONCLUSION: Obtaining a clear picture of the situation and providing consistent care across the country is a challenging task due to the decentralized organization of regions. We provide a first sketch, reporting that the model is applied unevenly, and we suggest feasible actions to improve the situation in our country and elsewhere. LEVEL OF EVIDENCE: Level V, narrative review.

The psychological impact of COVID-19 pandemic on patients included in a bariatric surgery program.

PURPOSE: The COVID-19 pandemic has radically impacted the world lifestyle. Epidemics are well-known to cause mental distress, and patients with a current or past history of obesity are at increased risk for the common presence of psychological comorbidities. This study investigates the psychological impact of the current pandemic in patients participating in a bariatric surgery program. METHODS: Patients were consecutively enrolled during the Italian lockdown among those waiting for bariatric surgery or attending a post-bariatric follow-up, and were asked to complete through an online platform the Depression Anxiety Stress Scales-21 and a self-assessment questionnaire of 22 items evaluating the resilience, change in eating behavior and emotional responses referring to the ongoing pandemic. RESULTS: 59% of the 434 enrolled subjects reported of being worried about the pandemic, and 63% specifically reported of being worried about their or their relatives' health. 37% and 56% felt lonelier and more bored, respectively. 66% was hungrier with increased frequency of snacking (55%) and 39% reported more impulse to eat. Noteworthy, 49% felt unable to follow a recommended diet. No difference in terms of psychological profile was recorded among pre and post-bariatric subjects. Logistic regression analysis on post-bariatric patients showed a relationship between snacking, hunger, eating impulsivity, and anxiety, stress, and/or depression symptoms. CONCLUSION: The pandemic led to increased psychological distress in patients with a current or past history of obesity, reducing quality of life and affecting dietary compliance. Targeted psychological support is warranted in times of increased stress for fragile subjects such as pre- and post-bariatric patients. LEVEL OF EVIDENCE: Level V: cross-sectional descriptive study.

Obesity and SARS-CoV-2: A population to safeguard.

Evidence has lately emerged regarding an increased risk of SARS-CoV-2 with worse prognosis in patients with obesity, especially among the young. Weight excess is a well-established respiratory disease risk factor, and the newly reported correlation is therefore unsurprising. The underlying pathophysiology is likely multi-stranded, ranging from complement system hyperactivation, increased Interleukin-6 secretion, chronic inflammation, presence of comorbidities such as diabetes and hypertension, and a possible local, detrimental effect within the lung. Further understanding the link between obesity and SARS-CoV-2 is crucial, as this could aid proper tailoring of immunomodulatory treatments, together with improving stratification among those possibly requiring critical care.

Nickel Sensitivity Is Associated with GH-IGF1 Axis Impairment and Pituitary Abnormalities on MRI in Overweight and Obese Subjects.

Nickel (Ni) is a ubiquitous metal, the exposure of which is implied in the development of contact dermatitis (nickel allergic contact dermatitis (Ni-ACD)) and Systemic Ni Allergy Syndrome (SNAS), very common among overweight/obese patients. Preclinical studies have linked Ni exposure to abnormal production/release of Growth Hormone (GH), and we previously found an association between Ni-ACD/SNAS and GH-Insulin-like growth factor 1 (IGF1) axis dysregulation in obese individuals, altogether suggesting a role for this metal as a pituitary disruptor. We herein aimed to directly evaluate the pituitary gland in overweight/obese patients with signs/symptoms suggestive of Ni allergy, exploring the link with GH secretion; 859 subjects with overweight/obesity and suspected of Ni allergy underwent Ni patch tests. Among these, 106 were also suspected of GH deficiency (GHD) and underwent dynamic testing as well as magnetic resonance imaging for routine follow up of benign diseases or following GHD diagnosis. We report that subjects with Ni allergies show a greater GH-IGF1 axis impairment, a higher prevalence of Empty Sella (ES), a reduced pituitary volume and a higher normalized T2 pituitary intensity compared to nonallergic ones. We hypothesize that Ni may be detrimental to the pituitary gland, through increased inflammation, thus contributing to GH-IGF1 axis dysregulation.

Testicular histopathology, semen analysis and FSH, predictive value of sperm retrieval: supportive counseling in case of reoperation after testicular sperm extraction (TESE).

BACKGROUND: To provide indicators for the likelihood of sperm retrieval in patients undergoing testicular sperm extraction is a major issue in the management of male infertility by TESE. The aim of our study was to determine the impact of different parameters, including testicular histopathology, on sperm retrieval in case of reoperation in patients undergoing testicular sperm extraction. METHODS: We retrospectively analyzed 486 patients who underwent sperm extraction for intracytoplasmic sperm injection and testicular biopsy. Histology was classified into: normal spermatogenesis; hypospermatogenesis (reduction in the number of normal spermatogenetic cells); maturation arrest (absence of the later stages of spermatogenesis); and Sertoli cell only (absence of germ cells). Semen analysis and serum FSH, LH and testosterone were measured. RESULTS: Four hundred thirty patients had non obstructive azoospermia, 53 severe oligozoospermia and 3 necrozoospermia. There were 307 (63%) successful sperm retrieval. Higher testicular volume, lower levels of FSH, and better histological features were predictive for sperm retrieval. The same parameters and younger age were predictive factors for shorter time for sperm recovery. After multivariable analysis, younger age, better semen parameters, better histological features and lower values of FSH remained predictive for shorter time for sperm retrieval while better semen and histology remained predictive factors for successful sperm retrieval. The predictive capacity of a score obtained by summing the points assigned for selected predictors (1 point for Sertoli cell only, 0.33 points for azoospermia, 0.004 points for each FSH mIU/ml) gave an area under the ROC curve of 0.843. CONCLUSIONS: This model can help the practitioner with counseling infertile men by reliably predicting the chance of obtaining spermatozoa with testicular sperm extraction when a repeat attempt is planned.

Rethinking weight loss treatments as cardiovascular medicine in obesity, a comprehensive review.

The global escalation of obesity has made it a worldwide health concern, notably as a leading risk factor for cardiovascular disease (CVD). Extensive evidence corroborates its association with a range of cardiac complications, including coronary artery disease, heart failure, and heightened vulnerability to sudden cardiac events. Additionally, obesity contributes to the emergence of other cardiovascular risk factors including dyslipidaemia, type 2 diabetes, hypertension, and sleep disorders, further amplifying the predisposition to CVD. To adequately address CVD in patients with obesity, it is crucial to first understand the pathophysiology underlying this link. We herein explore these intricate mechanisms, including adipose tissue dysfunction, chronic inflammation, immune system dysregulation, and alterations in the gut microbiome.Recent guidelines from the European Society of Cardiology underscore the pivotal role of diagnosing and treating obesity to prevent CVD. However, the intricate relationship between obesity and CVD poses significant challenges in clinical practice: the presence of obesity can impede accurate CVD diagnosis while optimizing the effectiveness of pharmacological treatments or cardiac procedures requires meticulous adjustment, and it is crucial that cardiologists acknowledge the implications of excessive weight while striving to enhance outcomes for the vulnerable population affected by obesity. We, therefore, sought to overcome controversial aspects in the clinical management of heart disease in patients with overweight/obesity and present evidence on cardiometabolic outcomes associated with currently available weight management interventions, with the objective of equipping clinicians with an evidence-based approach to recognize and address CVD risks associated with obesity.

Editorial for "The Role of Ketogenic Diet in Human Health and Diseases": The Multifaceted Impact of Ketogenic Diets on Health and Disease.

Effects of diet and antihyperglycemic drugs on erectile dysfunction: A systematic review.

BACKGROUND: Erectile dysfunction is recognized as one of the complications of diabetes mellitus. To date, a wide gap of knowledge is present on the efficacy of pharmacological treatments of diabetes mellitus on erectile function, acting not only through metabolic control. Similarly, the effects of different diet regimens on erectile dysfunction are still debated. OBJECTIVES: We aimed to explore the effects of diet and antihyperglycemic drugs, considering both old and novel therapeutic approaches, on erectile function. MATERIALS/METHODS: We performed a systematic review, following the PRISMA guidelines. The research was conducted on studies reporting erectile dysfunction assessment in subjects with diabetes and the relationship with diet and antihyperglycemic drugs. RESULTS: The Mediterranean diet was effective in most studies for the protection of erectile function. Furthermore, antihyperglycemic drugs seem to show an overall protective role on erectile function. DISCUSSION/CONCLUSION: Although encouraging results are present for all classes of antihyperglycemic drugs, several studies are needed in humans, mainly on acarbose, pioglitazone, dipeptidyl-peptidase-4 inhibitors, and sodium-glucose cotransporter-2 inhibitors.

Women with type 1 diabetes gain more weight during pregnancy compared to age-matched healthy women despite a healthier diet: a prospective case-control observational study.

PURPOSE: Women with type 1 diabetes mellitus (T1D), especially those with suboptimal glucose control, have 3-4 greater chances of having babies with birth defects compared to healthy women. We aimed to evaluate glucose control and insulin regimen modifications during the pregnancy of women with T1D, comparing the offspring's weight and the mother's weight change and diet with those of non-diabetic, normal-weight pregnant women. METHODS: Women with T1D and age-matched healthy women controls (CTR) were consecutively enrolled among pregnant women with normal weight visiting our center. All patients underwent physical examination and diabetes and nutritional counseling, and completed lifestyle and food intake questionnaires. RESULTS: A total of 44 women with T1D and 34 healthy controls were enrolled. Women with T1D increased their insulin regimen during pregnancy, going from baseline 0.9 ± 0.3 IU/kg to 1.1 ± 0.4 IU/kg (p = 0.009), with a concomitant significant reduction in HbA1c (p = 0.009). Over 50% of T1D women were on a diet compared to < 20% of healthy women (p < 0.001). Women with T1D reported higher consumption of complex carbohydrates, milk, dairy foods, eggs, fruits, and vegetables, while 20% of healthy women never or rarely consumed them. Despite a better diet, women with T1D gained more weight (p = 0.044) and gave birth to babies with higher mean birth weight (p = 0.043), likely due to the daily increase in insulin regimen. CONCLUSION: A balance between achieving metabolic control and avoiding weight gain is crucial in the management of pregnant women with T1D, who should be encouraged to further improve lifestyle and eating habits with the aim of limiting upward insulin titration adjustments to a minimum.
