RESUMEN
OBJECTIVES: Endometriosis is a disease that involves the ectopic growth of the endometrial tissue outside the uterine cavity. Its average occurrence is about 10% of women of reproductive age. Making a diagnosis of the disease is commonly long-lasting and ambiguous due to the wide variety and intensity of symptoms. The aim of the study is to determine factors affecting the quality of life of women struggling with endometriosis. MATERIAL AND METHODS: A cross-sectional study was conducted using a diagnostic survey method with the use of the author's questionnaire and the WHOQOL-BREF questionnaire. The study population included 650 people (group with endometriosis - 361 women and group without endometriosis - 289 women). RESULTS: In the group of women with endometriosis, the mean age was significantly higher (31.87 vs 24.99). Difficulties with conception were significantly more common (51.67%) in the endometriosis group compared to 5.52% in the non-endometriosis group. In each area, the quality of life of women with endometriosis was significantly lower (p = 0.000). Women with the history of the disease of over 3 years significantly more often complained of dyspareunia (p = 0.048), bladder pain (p = 0.01) and lower back pain (p = 0.029). CONCLUSIONS: Endometriosis significantly reduces women's quality of life. Factors that deteriorate the quality of life of women with endometriosis include severe pain, infertility, dyspareunia and reduced satisfaction in various spheres of life (somatic, mental, social). More research is necessary to improve the quality of life of women with endometriosis.
