Obesity and Clinical Riskiness Relationship: Therapeutic Management by Dietary Antioxidant Supplementation--a Review.

ABSTRACT

Obesity is a global health problem affecting all age groups, leading to many complications such as type 2 diabetes, systemic hypertension, cardiovascular disease, dyslipidemia, atherosclerosis, and stroke. Physiologically, obesity arises from metabolic changes in the tissues and organs of the human body; these changes result in an imbalance between energy intake and energy expenditure, which in turn results in increased fat accumulation in adipose tissue. Such fat accumulation predisposes individuals to development of several health problems. Two different obesity treatment drugs are currently on the market; Orlistat, which reduces intestinal fat absorption via inhibiting pancreatic lipase, and Sibutramine, an anorectic or appetite suppressant. Both drugs have hazardous side effects, including increased blood pressure, dry mouth, constipation, headache, and insomnia. For this reason, a wide variety of natural materials have been explored for their obesity treatment potential. Therefore, the present review focuses on the safety and efficacy of some herbal medicines in the management of obesity through covering their beneficial effects and mechanism of action.
