Polycystic ovary syndrome (PCOS) causes symptoms like insulin resistance, hormonal imbalance, and weight gain, often resulting in a “PCOS belly,” a colloquial term that has been popularized in social media. The fat is concentrated around the abdomen, and for females with insulin resistance, it is harder to lose because of hormonal fluctuations and high levels of insulin. The dietary and lifestyle changes, as well as specific medications prescribed by doctors, can help manage weight loss.

Polycystic ovary syndrome (also known as PCOS) is one of the most common endocrine diseases among women. According to the World Health Organization, PCOS affects 8–13% of all women of reproductive age. And, as you may already know, this disease also causes higher risks of infertility among women.
Symptoms vary, but the most common ones are insulin resistance, diabetes, reproductive hormone imbalance, missed periods, and weight gain. Notably, the last symptom isn’t only about weight in general.
PCOS causes a phenomenon known as “PCOS belly”—an apple-shaped belly with a prominent fat pad around the middle of the waist. Let’s explore everything you may want to know about this PCOS symptom and how to treat it.
PCOS belly is characterized as an accumulation of abdominal fat in women diagnosed with PCOS. Since PCOS causes hormonal changes and weight gain, women may have increased body fat and weight gain all over the body.
But, in some cases, there is a higher chance of fat concentrated on the belly that is hard to shed. Even when having an ideal body mass index, PCOS makes it much harder to get rid of belly fat.
According to Dr. Trish Kahawita, the two main reasons for PCOS belly are hormonal fluctuations and insulin resistance.
PCOS makes it harder for the body to properly use the hormone insulin, which is supposed to help convert sugars and starches from foods into energy. Insulin resistance causes insulin and sugar to build up in the bloodstream and stored as fat instead of being converted into energy.
These high insulin levels in the bloodstream increase the production of male sex hormones called androgens. High levels of this hormone often lead to symptoms like excessive body hair growth, acne, irregular periods, and weight gain.
Even though you may know what a PCOS belly looks like, you may still wonder whether it is possible to confuse it with just obesity or even a pregnant belly. Let’s learn the differences:
PCOS belly shape: | General obesity belly shape: | |
Fat distribution | PCOS causes an “apple-shaped” body, with weight gain that is concentrated around the abdomen, while the rest of the body might be without significant changes. | Fat is more evenly distributed throughout the body, though it can still be concentrated in areas like the abdomen, hips, and thighs. The rest of the body also shows visible weight gain changes. |
Appearance | The belly may appear more distended and firm compared to other types of fat distribution. | The fat in general obesity is often softer and more evenly spread across different parts of the body. |
Underlying causes | Hormonal imbalance, insulin resistance, and metabolic syndrome are key reasons. | Overeating, lack of physical activity, genetics, and related metabolic conditions. |
PCOS belly | Pregnant belly | |
Shape and firmness | The belly is generally more round and firm due to the central accumulation of fat. It does not grow or change shape significantly over a short period. | The pregnant belly is more protruded and can be softer, depending on the stage of pregnancy. The belly grows and changes over the course of the pregnancy. |
Consistency | Firmness is caused by fat and sometimes bloating rather than a growing uterus or fluid accumulation associated with pregnancy. | The belly is firm because of the growing fetus, uterus, and amniotic fluid. |
PCOS-related weight gain:

If there are any concerns regarding unusual weight gain or changes in body shape, it is essential to consult with a doctor for accurate diagnosis and appropriate treatment.
Since PCOS-related weight gain is triggered by male hormones, fat is usually concentrated on the belly. That is where men traditionally tend to gain weight. So, instead of having more pear shape, women with PCOS usually have a so-called “apple” body shape.
Key changes in the body shape experienced by women with PCOS are:

Medical treatments should only be prescribed by a healthcare professional; the information below is only for educational purposes. Here are some of the treatments that doctors may consider:
The short answer is “no.” While belly fat is a common symptom of PCOS, not all women with the disease will have significant abdominal fat.
Ozempic is not specifically approved for PCOS. However, healthcare professionals sometimes consider this drug because of its positive effects on weight loss and insulin resistance.
Surgery might be an option, but it is often considered only after dietary management, lifestyle changes, and medications. If these don’t work, consult healthcare professionals for more options, including surgery.
Recognizing a PCOS belly is crucial for effective management of the condition. Hormonal imbalances and insulin resistance are primary reasons for abdominal fat accumulation in women with PCOS.
Treatment and symptom management involve a combination of lifestyle modifications, including a balanced diet, regular exercise, and medical interventions prescribed by healthcare providers. Consulting with healthcare professionals is essential to get a personalized treatment plan.
