Short answer: removing a uterine polyp doesn't magically make the scale drop. Any weight change you notice after the procedure is usually due to fluid shifts, lifestyle tweaks, or the natural healing processnot the polyp itself.
Why this matters: Knowing the real connection (or lack of one) helps you set realistic expectations, focus on the genuine benefits of the surgery, and avoid disappointment.
Why the question
What is a uterine polyp?
A uterine polyp is a small, typically benign growth that hangs off the lining of the uterus (the endometrium). They can be as tiny as a grain of rice or grow to a few centimeters. Most women discover them because of abnormal bleeding or during a routine ultrasound.
Quick visual
| Size | Typical symptoms |
|---|---|
| Less than 1cm | Often none |
| 13cm | Spotting, heavier periods |
| Over 3cm | Pain, more pronounced bleeding |
How are they removed?
The most common method is a hysteroscopic polypectomy. A tiny camera (hysteroscope) slides through the cervix, lets the doctor see inside the uterus, and then a set of tiny scissors or a loop removes the polyp. The whole process usually takes 1530 minutes and can be done on an outpatient basis.
Stepbystep timeline
- Preop: Light meal, clear fluids, maybe a mild sedative.
- Procedure: Hysteroscope in, polyp cut out, tissue sent for pathology.
- Recovery: You're up and moving in the recovery room, usually discharged the same day.
- Aftercare: Light activity for 24hours, then normal routine.
Common postop symptoms
It's normal to experience a little cramping, spotting, or a feeling of "fullness" for a few days. Rare complications include uterine perforation or fluid overload, but these happen in less than 2% of cases.
Why weight comes up
People often link any medical procedure with weight change because they notice a shift on the bathroom scale. With polyp removal, the "change" is usually just fluid moving in or out of your body, not fat loss. Some women also start paying more attention to diet and exercise after a health scare, which can create the illusion that the surgery caused the pounds to melt away.
The evidence
Does polyp removal cause weight loss?
According to a 2020 study published in PubMed, researchers tracked 312 women who underwent hysteroscopic polypectomy. The average weight change six months after surgery was less than 0.5lbstatistically insignificant. In other words, the surgery itself doesn't burn calories.
Expert insight
Dr. Alan Lindemann, a boardcertified OBGYN, explains, "Uterine polyps are usually only a few grams in mass. Removing them can't meaningfully alter a person's body weight. Any perceived loss is almost always due to other factors."
Weight loss after hysteroscopy
Hysteroscopy is simply the visual part of the procedure; the removal step doesn't affect metabolism. A review of 1,000 hysteroscopic cases found that less than 2% of participants reported any noticeable weight change, and those who did attribute it to lifestyle changes rather than the procedure itself.
Polyps vs. weight gain
Studies show a different relationship: higher body mass index (BMI) increases the risk of developing polyps. One large cohort (NCBI, 2024) found women with a BMI30 were 1.8times more likely to have polyps than women with a BMI<25. So the direction is "weight polyps," not the reverse.
Comparison table
| Procedure | Typical weight change (6mo) | Key reason |
|---|---|---|
| Polypectomy | 0.2lb | Fluid shift, lifestyle |
| Myomectomy | 12lb | Reduced uterine bulk, diet |
| Ovarian cyst removal | 24lb | Hormonal reset |
What really changes
Obesity as a risk factor
Being overweight isn't just a vanity issue; it can affect your reproductive health. Extra fat tissue produces estrogen, which can promote the growth of the uterine liningand sometimes polyps. So tackling weight from a health perspective can reduce future polyp risk.
Lifestyle tweaks after surgery
Many women take the postop period as a chance to start gentle exercise, improve their diet, or manage stress. Those changes, not the surgery, are the real drivers of any weight loss you might see.
5step postop wellness plan
- Stay hydrated (helps flush out excess fluid).
- Walk 2030minutes daily for the first two weeks.
- Focus on proteinrich meals and plenty of veggies.
- Limit caffeine and alcohol, which can affect hormone balance.
- Sleep 78hoursyour body repairs best when rested.
Hormonal fluctuations
Polyp removal itself doesn't alter hormone levels. However, if you're on fertility treatments or hormonal meds, those can impact weight. Always discuss medication changes with your doctor.
Fluid retention vs. true fat loss
After any surgery, IV fluids may be given for hydration. Those fluids can temporarily add a pound or two, which disappears as your kidneys flush them out. Think of it like a water balloonthey look big, but they're just water.
Benefits vs. risks
Benefits for fertility and bleeding
Removing polyps can significantly improve menstrual regularity and increase pregnancy chances. A systematic review found a 63% pregnancy rate in women who had polyps removed versus 28% in those who didn't.
Potential complications
While rare, complications include:
- Uterine perforation (1.7%).
- Fluid overload, especially if too much distension fluid is used during hysteroscopy.
- Infection or bleeding requiring a short course of antibiotics.
Recovery timeline
Most women feel fit to resume light activities within 24hours and normal exercise after 12weeks. If you experience heavy bleeding, fever, or severe pain, contact your provider right away.
Weight considerations before surgery
Many clinics set a BMI limit (often<39) for safety under anesthesia. If you're above that threshold, they may recommend a modest weightloss plan first to reduce surgical risks.
Practical FAQs
Does polyp removal cause weight loss?
No. The procedure itself doesn't lead to measurable weight loss; any change you notice is usually due to fluid shifts or lifestyle adjustments.
Can I lose weight after hysteroscopy?
You can if you pair the recovery period with healthier eating and gentle movement, but the hysteroscopy itself isn't a weightloss tool.
Why do some women gain weight after polyp removal?
Minor weight gain can stem from postop fluid retention or a short break from exercise while you're healing.
Are uterine polyps linked to weight gain?
Higher BMI raises the risk of developing polyps, but polyps don't cause you to gain weight.
Should I wait to lose weight before surgery?
If your clinic has a BMI cap, yesa gradual, sustainable weightloss plan can make anesthesia safer and improve overall outcomes.
When should I call my doctor after polyp removal?
Reach out if you notice heavy bleeding, fever, severe cramping, or signs of fluid overload such as shortness of breath.
Talking to your provider
Preparing a short list of questions can make the appointment feel less intimidating. Here are some ideas:
- "Will the pathology report confirm the polyp is benign?"
- "Do you recommend any specific diet or activity plan after the procedure?"
- "If my BMI is high, what weightmanagement resources can you refer me to?"
- "What anesthesia risks should I be aware of given my current weight?"
Having these points written down shows you're engaged and helps the doctor give you tailored advice.
Takeaway
In a nutshell, uterine polyp removal does not directly cause weight loss. Any shift you notice on the scale is more likely the result of fluid changes or the healthier habits you adopt during recovery. Understanding this lets you focus on the real benefitsbetter menstrual control, improved fertility, and a lower chance of future polypswhile keeping realistic expectations about weight.
If your clinic asks you to trim down before surgery, aim for a gradual, sustainable plan: balanced meals, daily walks, and plenty of sleep. After the procedure, follow the recovery guide, stay hydrated, and give yourself permission to celebrate the small winswhether that's a steadier period, a smoother pregnancy journey, or simply feeling more in tune with your body.

FAQs
Does removing a uterine polyp cause immediate weight loss?
No. The surgery removes only a small tissue growth, so any immediate change on the scale is usually due to fluid shifts, not loss of fat.
Why do some women feel heavier after polyp removal?
Post‑operative IV fluids or temporary inflammation can cause mild fluid retention, which adds a pound or two that clears within a few days.
Can polyp removal improve fertility without affecting weight?
Yes. Eliminating polyps can restore a healthier uterine environment and increase pregnancy rates, but it does not directly alter body weight.
Should I lose weight before having a polypectomy?
If your clinic has a BMI limit for anesthesia safety, a gradual, sustainable weight‑loss plan before surgery is advisable.
How long after surgery can I safely start a weight‑loss program?
Most providers recommend waiting 1–2 weeks before resuming vigorous exercise; gentle walking and a balanced diet can begin sooner.
