Thank you for asking Healthcare majic. My name is Dr Ehsan Ullah & I have gone through your query. you have mentioned about Bilateral Salpingo oophorectomy in 2009, & you main concern is regarding Weight gain after this Surgery... First of all you should know that in this surgical procedure Both Fallopian tubes & Ovaries are removed ... Fallopian tubes are just transit for Ova or secretions while Ovaries have many Important roles in the Female life. like Development of breast & Sexual Characteristics by Secretion of two main hormones Estrogen & Progestrone... They have various effects on breasts, Uterus , Pregnancy etc well Estrogen apart from these functions is also Concerned with fat distribution in the hips, legs, and breasts ... So after this surgery , when there is loss of these hormones so Fat distribution is not as pre-surgery level... Although body has other sites too (Some Breasts , vessels & Bones mesenchymal Cells) which produce and compensate for this hormonal issue , however , those may act locally at those sites. All you need is to visit your physician & may need guidance from Dietician & Endocrinologist regarding this issue Hope this may help you. Let me know if anything not clear. Thanks.
