PCOS symptoms diet considerations

Overview

Polycystic ovary syndrome (PCOS) is a common hormone problem that affects how a woman's ovaries work. It can disrupt monthly periods, cause extra male-type hormones, and lead to small fluid-filled sacs (cysts) on the ovaries.

Yes, PCOS affects about 1 in every 10 women of childbearing age.

PCOS usually begins during the teenage years or early twenties. It can affect anyone with ovaries, regardless of weight or background.

Symptoms

Common symptoms

• Irregular, infrequent, or very heavy periods
• Excess hair growth on the face, chest, or back (hirsutism)
• Acne or oily skin
• Weight gain, especially around the belly
• Thinning hair on the scalp
• Trouble getting pregnant

Symptoms in children

• Irregular periods after puberty
• Acne or unwanted hair growth that seems more than usual
• Periods that remain irregular for several years after they start

Symptoms in older adults

• Symptoms may change near menopause; cycles might become more regular, but extra hair growth and insulin resistance can continue.
• Older adults with PCOS have a higher risk of type 2 diabetes and heart disease, so periodic check-ups matter.

Causes

Main causes

• The exact cause isn't known, but PCOS involves a hormonal imbalance, including higher levels of androgens (hormones like testosterone).
• Many women with PCOS have insulin resistance, meaning the body's cells don't respond well to insulin. This can raise insulin and androgen levels.
• Genes can play a role, since PCOS often runs in families.

Risk factors

• A parent or sibling with PCOS
• Being overweight or having obesity
• Having type 2 diabetes in the family
• Being physically inactive

When to see a doctor

See a doctor urgently if:

• Sudden, severe pelvic pain
• Very heavy bleeding with dizziness
• Signs of a blood clot in your leg

Book a routine appointment if:

• If your periods are irregular for several months, or you have acne or extra hair growth that bothers you.
• If you are under 35 and have been trying to get pregnant for 12 months without success (or 6 months if you are 35 or older).
• If you are planning to become pregnant and have PCOS symptoms.

Diagnosis

Doctors often diagnose PCOS after asking about your symptoms, doing a physical exam, and checking blood tests and an ultrasound (a scan of the ovaries).

Tests that may be done

• Blood tests to check hormone levels (such as testosterone) and blood sugar
• Blood tests to check cholesterol and blood pressure
• An ultrasound of your pelvis to look for cysts or thickening in the ovaries
• A pelvic exam to check your reproductive organs

What to expect at your appointment

Your doctor may send you to a specialist called an endocrinologist (hormone doctor) or a gynecologist. The process usually isn't painful, but the ultrasound may feel a little uncomfortable. You may need to come back for follow-up blood tests.

Treatment

There is no cure for PCOS, but it can be managed well. Treatment aims to relieve symptoms, improve ovulation if you want to get pregnant, and lower the risk of long-term health problems like diabetes and heart disease.

Self-care at home

• Follow a balanced diet with whole grains, vegetables, fruits, and lean protein.
• Move your body most days — aim for 150 minutes of moderate activity each week.
• Work toward a healthy weight; losing even 5–10% of your body weight can improve symptoms.
• Get enough sleep and find healthy ways to manage stress.

Medical treatments

Medicines can help in different ways. Hormonal birth control (pill, patch, or vaginal ring) can make periods regular and reduce acne and extra hair. Other medicines can help with insulin resistance or encourage ovulation, especially if you want to become pregnant. Your doctor will choose a treatment plan based on your symptoms and goals.

When is surgery considered?

Surgery is not a first treatment for PCOS. In a few cases, a small procedure called ovarian drilling (using a laparoscope) can improve ovulation when medicines haven't worked, but it's not common.

Living with this condition

Living well with PCOS means keeping a regular schedule for meals, exercise, and sleep. Track your periods and note any changes in symptoms to help you and your doctor make care decisions.

Lifestyle tips

• Eat regular meals and avoid long gaps that cause blood sugar dips.
• Choose high-fiber snacks like fruit, nuts, or hummus.
• Limit sugary drinks, white bread, and processed snacks.
• Include strength training at least twice a week.
• Avoid smoking and limit alcohol.

Diet and exercise

A low-glycemic-index (GI) diet can help. Low-GI foods — like oats, quinoa, lentils, berries, and leafy greens — release energy slowly and keep blood sugar balanced. Pair carbs with protein or healthy fat, like apple slices with peanut butter. Regular exercise, including brisk walking or cycling, helps your body use insulin better.

Mental health and emotional wellbeing

Living with PCOS can be stressful. Unwanted hair growth, weight gain, or difficulty getting pregnant can affect self-esteem and mood. Many people feel anxious or depressed. These feelings are valid, and support from a counselor or support group can make a real difference.

Prevention

You can't prevent PCOS itself, because it's linked to genes and hormones. But you can reduce the impact of symptoms and lower your risk of long-term problems by keeping a healthy weight, eating well, staying active, and not smoking.

Screening programmes

Screening for type 2 diabetes and high cholesterol is recommended for women with PCOS, especially if you are overweight. If you become pregnant, you may be screened earlier for gestational diabetes.

Complications

If left untreated

• Higher risk of type 2 diabetes, high blood pressure, and heart disease
• Difficulty getting pregnant and higher chance of pregnancy complications
• Increased risk of uterine lining (endometrial) cancer because of missed periods
• Sleep apnea and non-alcoholic fatty liver disease

Long-term outlook

The outlook is often positive. Many women with PCOS manage their symptoms with a healthy lifestyle and medical guidance. If you want to become pregnant, treatments can improve your chances. Staying connected to your healthcare team and making small, consistent changes can help you live well for many years.
