Weight Changes After Hysterectomy: Questions to Discuss

When should you contact your surgeon after a hysterectomy?

Before anything about weight: if you are recovering from surgery and any of the following happens, contact your surgeon. MedlinePlus's discharge instructions for abdominal hysterectomy list these reasons to call: 2

• A fever above 100.5°F (38°C)
• Bleeding, redness with warmth, or thick yellow or green drainage at the incision
• Pain that your pain medicine is not controlling
• Trouble breathing, chest pain, or a cough that will not go away
• Being unable to eat or drink, nausea or vomiting, or being unable to pass gas or have a bowel movement
• Pain or burning when you urinate, or being unable to urinate
• Foul-smelling vaginal discharge, bleeding heavier than light spotting, or heavy watery discharge
• Swelling, redness, or pain in one leg

If you have chest pain or trouble breathing, seek emergency care. This page cannot tell you whether a change in your body is expected, so a change in swelling, appetite, or weight during recovery belongs in a call to your surgeon, not in a wait-and-see pile.

Does a hysterectomy cause weight gain?

The research does not show that the uterus coming out is what moves weight. A hysterectomy is not one operation. A total hysterectomy removes the uterus and cervix, a partial one leaves the cervix, and a radical one removes surrounding tissue, usually to treat cancer. In each, the ovaries and fallopian tubes may or may not be removed. 1

That distinction is the one the studies hinge on. The ovaries make hormones that help maintain bone density and sexual health even when the uterus is gone. 3 If both ovaries are taken out, menopause symptoms will usually begin. 1

What do studies find about weight when the ovaries are kept or removed?

Two prospective studies are worth knowing, and they do not fully agree.

The Study of Women's Health Across the Nation (SWAN) followed 1,962 midlife women for up to 10 years: 1,780 who reached natural menopause, 76 who had a hysterectomy with their ovaries kept, and 106 who had a hysterectomy with both ovaries removed. 4 BMI rose in every group. After surgery or the final period, it rose faster in the bilateral oophorectomy group (0.21 BMI points a year) than after natural menopause (0.08 a year). Hysterectomy with the ovaries kept was not significantly different from natural menopause. Waist circumference rose in all groups with no difference by surgery. 4 The authors flag that the findings should not be generalized to younger women, and that women with a hysterectomy before enrolling were not eligible, so the surgical groups may not represent all women who have had one. 4

The WHAM study followed 95 premenopausal women having ovaries and tubes removed to lower cancer risk, and 99 comparison women who kept their ovaries. Both groups gained weight over 24 months, with no significant difference between them. The women who had surgery may have gained slightly more abdominal visceral fat, a difference of about 99 grams, and hormone therapy made no difference to weight or body composition in this study. 5 These women had a risk-reducing procedure rather than a hysterectomy for a gynecologic condition, so the groups are not the same as in SWAN.

Both studies are observational. They can show an association, not that surgery caused a given change.

What does the research cover, and what does it leave open?

Your situation	What the research above covers	What stays open
Uterus removed, ovaries kept	SWAN: BMI change not significantly different from natural menopause 4	Small groups; your own timeline and health history
Uterus and both ovaries removed	SWAN: faster BMI increase than natural menopause 4	WHAM found no weight difference at two years in a related group 5
Ovaries removed before natural menopause	WHAM: no weight difference at 24 months, slightly more visceral fat 5	Whether hormone therapy changes weight; one study found it did not
Radical hysterectomy for cancer	Not covered by either study	Treatment context differs; ask your oncology team

What should you ask your surgeon or clinician?

Bring these to a pre-surgery visit, a follow-up, or an appointment about weight:

• Which parts were or will be removed: uterus, cervix, ovaries, fallopian tubes?
• Will menopause symptoms be expected, and who manages them?
• Are hormone therapy questions part of this plan? Our guide to hormone therapy and GLP-1 treatment questions covers what to bring.
• Which numbers should we track, and how often?
• What activity is okay now? MedlinePlus advises avoiding strenuous exercise until your surgeon approves it. 2
• If weight is a concern later, which kind of weight care fits my history?

Weight care and menopause care are separate conversations that can share an appointment. A weight medicine does not treat menopause symptoms.

Common questions

Will I gain weight after my hysterectomy?

The studies cannot say. In the largest one here, women who kept their ovaries were not significantly different from natural menopause, and those who lost both ovaries gained BMI faster on average. Individual results vary.

Is a change in weight after surgery my fault?

No. Weight is a clinical topic, not a moral one. The studies above measured group averages and do not attribute any one person's weight to anything she did or did not do.
