Oophorectomy is the surgical removal of the ovaries. It is usually done to treat diseases involving the ovaries. After oophorectomy, the main source of estrogen and progesterone hormones in the body is lost. This can lead to symptoms like hot flashes, vaginal dryness, decreased libido, etc. To manage these symptoms, many doctors recommend starting hormone replacement therapy (HRT) after oophorectomy. The timing of starting HRT depends on several factors: Age at surgery - Younger patients (under 45 years): Recommended to start HRT immediately after surgery to manage symptoms and prevent complications like bone loss. - Older patients (over 45 years): Can wait for 3-6 weeks after surgery to see if symptoms develop before deciding to start HRT. Reason for surgery - Cancer prevention: No need to start HRT immediately. Can wait and see approach. - Symptom relief: Start HRT soon to prevent severe symptoms. Severity of menopausal symptoms - Start HRT sooner if symptoms like hot flashes, vaginal dryness, insomnia are severe and affecting quality of life. Type of HRT - Estrogen only: Generally recommended after oophorectomy as patient no longer has progesterone producing ovaries. Provides symptom relief. - Estrogen progesterone: Sometimes used short-term if patient retained her uterus to prevent risk of endometrial hyperplasia. Duration of HRT - Taken at least until the average age of menopause (51 years). Can be taken longer based on patient's risk-benefit profile. Monitoring on HRT - Regular follow-up to assess symptom relief, cancer risks, bone density, etc. Treatment is tailored to patient's changing needs. The goal is to start HRT at the right time to provide relieve symptoms and prevent long-term complications, while minimizing potential risks. An individualized approach is taken based on the patient's specific situation and health needs. I have refrained from including advertisements or inappropriate content.
