This study shows a broad analysis of gynaecological and obstetrical disturbances in patients with celiac disease in relation to their nutritional status and adherence to a gluten-free diet. Seventy-six adult celiac patients were analyzed according to nutritional status and 18 children/adolescents to gluten-free diet adherence. As controls, 84 adults and 22 adolescents with irritable bowel syndrome were used The significant findings were observed as follow: adult celiac patients, irrespective of the nutritional status, were younger than controls, presented delayed menarche, secondary amenorrhea, a higher percentage of spontaneous abortions, anemia and hypoalbuminemia. No differences were observed regarding the number of pregnancies, age at menopause and duration of the reproductive period. After treatment, patients presented with normal pregnancies and one patient presented spontaneous abortion. The adolescents who were not adherent to gluten-free diet presented delayed menarche and secondary amenorrhea. In conclusion, gluten per se could explain the disturbances and malnutrition would worsen the disease in a consequent vicious cycle. Therefore, celiac disease should be included in the screening of reproductive disorders.
