Most women at some point have to contend with weight gain. But for women with polycystic ovary syndrome (PCOS), losing weight can become a constant struggle.
PCOS is the most common hormonal disorder in women of childbearing age and can lead to issues with fertility. Women who have PCOS have higher levels of male hormones and are also less sensitive to insulin or are "insulin-resistant." Many are overweight or obese. As a result, these women can be at a higher risk of diabetes, heart disease, sleep apnea, and uterine cancer.
If you have PCOS, certain lifestyle changes can help you shed pounds and reduce the disease's severity.
Why does polycystic ovary syndrome cause weight gain?
PCOS makes it more difficult for the body to use the hormone insulin, which normally helps convert sugars and starches from foods into energy. This condition -- called insulin resistance -- can cause insulin and sugar -- glucose -- to build up in the bloodstream.
High insulin levels increase the production of male hormones called androgens. High androgen levels lead to symptoms such as body hair growth, acne, irregular periods -- and weight gain. Because the weight gain is triggered by male hormones, it is typically in the abdomen. That is where men tend to carry weight. So, instead of having a pear shape, women with PCOS have more of an apple shape.
Abdominal fat is the most dangerous kind of fat. That’s because it is associated with an increased risk of heart disease and other health conditions.
What are the risks associated with PCOS-related weight gain?
No matter what the cause, weight gain can be detrimental to your health. Women with PCOS are more likely to develop many of the problems associated with weight gain and insulin resistance, including:
- Type 2 diabetes
- High cholesterol
- High blood pressure
- Sleep apnea
- Endometrial cancer
Many of these conditions can lead to heart disease.
Experts think weight gain also helps trigger PCOS symptoms, such as menstrual abnormalities and acne.
What can I do to lose weight if I have polycystic ovary syndrome?
Losing weight not only cuts your risk for many diseases, it can also make you feel better. When you have PCOS, shedding just 10% of your body weight can bring your periods back to normal. It can also help relieve some of the symptoms of polycystic ovary syndrome.
Weight loss can improve insulin sensitivity. That will reduce your risk of diabetes, heart disease, and other PCOS complications.
To lose weight, start with a visit to your doctor. The doctor will weigh you and check your waist size and body mass index. Body mass index is also called BMI, and it is the ratio of your height to your weight.
Your doctor may also prescribe medication. Several medications are approved for PCOS, including birth control pills, anti-androgen medications and Metformin (Glucophage). The anti-androgen medications block the effects of male hormones. Metformin is a diabetes drug that helps the body use insulin more efficiently. It also reduces testosterone production. Some research has found that it can help obese women with PCOS lose weight.
In addition to taking medication, adding healthy habits into your lifestyle can help you keep your weight under control:
- Eat a high-fiber, low-sugar diet. Load up on fruits, vegetables, and whole grains. Avoid processed and fatty foods to keep your blood sugar levels in check. If you’re having trouble eating healthy on your own, talk to your doctor or a dietitian.
- Eat four to six small meals throughout the day, rather than three large meals. This will help control your blood sugar levels.
- Exercise for at least 30 minutes a day on most, if not all, days of the week.
- Work with your doctor to track your cholesterol and blood pressure levels.
- If you smoke, get involved in a program that can help you quit.
