Pain, heavy bleeding and digestive issues often prompt people to limit or refrain from engaging in extended physical activity; consequently they consume fewer calories.
Studies indicate that women living with endometriosis tend to have lower BMI (body mass index) scores. Furthermore, they appear slimmer during key timeframes such as adolescence and young adulthood.
Endometriosis and Weight Gain: What’s the connection
Bloating and fluid retention

An individual suffering from endometriosis has areas of endometrial-like tissue outside their uterus that develop, such as on their ovaries, fallopian tubes, bowel or bladder. These tissues respond to hormone changes in their bodies and cause menstruation pain every month; women may also experience abdominal or pelvic discomfort as a symptom.
Endometriosis sufferers frequently experience bloating and fluid retention that makes clothes feel tighter, leading to feelings of weight gain that affect self-image.
Research suggests that slim women are more prone to endometriosis than overweight or obese women, although its cause remains enigmatic.
One theory holds that fat cells store estrogen which could contribute to endometriosis development; other research has concluded that eating an abundant supply of fruits and vegetables helps lower risks associated with endometriosis; although to diagnose endometriosis effectively a laparoscopy remains the definitive method.
Hormonal birth control
Endometriosis sufferers often turn to hormone medications such as the birth control pill, vaginal ring or intrauterine device (IUD).
These pills and treatments aim to inhibit hormone production that thickens endometrial lining and causes bloating; slow tissue growth; reduce menstruation frequency by making cycles lighter; as well as reduce weight gain as side effects from taking such treatments. Unfortunately though, some takers experience weight gain due to taking such medicines.
Endometriosis symptoms often include abdominal and back pain, with accompanying diarrhea or constipation issues, leading to fluctuations in weight due to retention of fluid, as well as increases in appetite.
Studies indicate that women with endometriosis tend to be taller, thinner and have a lower BMI than their peers without it. This could be caused by late physical maturation or having an uneven pear-shape upper body structure; other possible factors could include having late menstruation onset/sexual activity which means less exposure to weight changes during pregnancy.
Hormone therapy
Endometriosis sufferers frequently exhibit symptoms including bloating, pain and heavy menstrual cycles that could be misinterpreted by doctors as evidence of IBS (irritable bowel syndrome).
If you have endometriosis, your healthcare provider may recommend hormone therapy medications designed to stop estrogen production and slow or stop its effects on endometrial tissue growth. While such therapies can have their own set of side effects like fluid retention or increased appetite, they usually produce results within days or even hours of being prescribed.
Chronic endometriosis pain can make it challenging to be physically active and maintain a healthy weight, increasing your likelihood of eating unhealthy foods and leading to weight gain. Exercise is an excellent way to keep your body healthy by relieving pain, fatigue, depression and other symptoms that contribute to weight gain.

Surgery
Many individuals with endometriosis experience weight gain due to its associated pain, bloating and other symptoms, which may appear like weight gain and may alter how their clothes fit. This bloating may appear as weight gain causing clothing sizes to change accordingly.
Pain caused by endometriosis may prevent physical activity and thus help lower calorie consumption, leading to weight loss. But evidence also shows that decreasing fat in diet may aid weight reduction.
Studies have indicated that slim women are more likely to develop endometriosis than their heavier counterparts; however, this does not prove the condition directly.
Surgery may help alleviate some of the symptoms that cause pain and bloating. Before considering this route, a woman should discuss with their consultant and surgeon the potential benefits and drawbacks of this procedure. They can also recommend additional forms of therapy including hormone replacement therapy as possible treatments.
Does Endometriosis Cause Weight Gain?
Endometriosis is a condition characterized by the growth of tissue similar to the uterine lining outside the uterus.
While endometriosis itself may not directly cause weight gain, there are various ways in which it can be associated with changes in body weight. Let’s delve into some of the reasons how endometriosis may contribute to weight gain:
Endometriosis often leads to bloating and fluid retention, which are common symptoms. This can cause fluctuations in weight and create a feeling of heaviness. Additionally, bloating may affect how clothes fit.
Hormonal imbalances can contribute to various symptoms in endometriosis. This condition, which relies on estrogen, may lead to weight gain when estrogen levels are elevated. Excess or unopposed estrogen, where progesterone fails to provide a counterbalance, can result in bloating, irregular menstrual cycles, and breast tenderness.
Limited physical activity: Endometriosis can cause such intense pain that individuals may find it difficult to engage in exercise or other physical activities essential for managing a healthy weight. Medication: Some endometriosis treatments may cause weight gain.
Although there are anecdotal accounts linking weight gain to endometriosis, formal research on this particular topic remains limited. Individuals with endometriosis who suspect that their condition may be contributing to weight gain or hindering weight loss endeavors should consider consulting with a healthcare professional.
How Can Endometriosis Affect Metabolism and Hormones
Endometriosis can affect metabolism and hormones in several ways:
Hormonal imbalances can play a significant role in the development of endometriosis. This condition is closely tied to estrogen levels, as elevated amounts of estrogen can stimulate inflammation and the growth of endometrial tissue within the body. When hormonal imbalances occur, especially an excess of estrogen or unopposed estrogen, various symptoms may arise. These can include bloating, irregular menstrual periods, breast tenderness, and weight gain.
Metabolic changes can result from endometriosis, affecting weight management in individuals. Management of this condition often entails hormone treatments like oral contraceptives and progestins, which can lead to side effects such as bloating, weight gain, and acne.
Limited physical activity can result from endometriosis-induced pain, which diminishes one’s inclination for exercise and other activities essential for maintaining a healthy weight.
Estrogen receptors are closely linked to the metabolism of steroids and related pathways. In the development and persistence of endometriotic tissue, estrogen receptors play a significant role. Women with autonomous endometriotic estradiol production would not benefit greatly from treatments that inhibit ovarian estradiol production, as they possess limited benefits.
The usage of estrogen receptor ligands, inhibitors, and agonists further validates the importance of these receptors in endometriosis.
It is worth noting that although endometriosis may contribute to weight gain, it is not a direct symptom of the condition. Individuals suffering from endometriosis who suspect a connection between their symptoms and weight fluctuations should consult with a healthcare professional for further evaluation and guidance.
What Are Some Ways to Manage Weight Gain Caused by Endometriosis

Endometriosis may not directly cause weight gain, but its treatments can. Manage weight gain with these steps:
- Eat a balanced diet: Consume fruits, vegetables, lean protein, and whole grains to control weight and reduce inflammation.
- Do exercise: Stay active to manage weight changes, boost mood, and increase energy.
- Hormone treatments: Discuss alternatives with your doctor if weight gain occurs due to hormone treatments.
- Surgery: Consider removing endometrial tissue causing weight gain after consulting your doctor.
- Pain management: Control pain to maintain a healthy weight and engage in physical activities.
- Consult a doctor: If you suspect endometriosis-related weight issues, talk to a healthcare professional.
