PCOS symptoms that comes and goes

Overview

PCOS (polycystic ovary syndrome) is a common hormonal condition that affects how the ovaries work. It can cause irregular periods, extra body hair, acne, and weight gain. Symptoms can vary over time — they may come and go based on weight, stress, age, and other factors.

Yes, PCOS is one of the most common hormonal conditions worldwide.

PCOS usually starts during the teenage years or early twenties. It affects people with ovaries — including women, trans men, and non-binary individuals — and can continue into middle age and beyond.

Symptoms

Common symptoms

• Irregular, infrequent, or heavy periods
• Acne on the face, chest, or back
• Excess hair growth on the face, chest, or back (hirsutism)
• Thinning hair on the scalp
• Weight gain or difficulty losing weight
• Darkened skin patches in the neck or armpits
• Mood changes, anxiety, or low mood

Causes

Main causes

• The exact cause of PCOS isn't fully known, but it involves imbalanced hormones, especially higher levels of androgens (male-type hormones).
• Insulin resistance — when cells in the body don't respond properly to insulin — is common in PCOS and can make symptoms worse.
• There is a strong genetic link, as PCOS often runs in families.

Risk factors

• Family history of PCOS
• Obesity or being above a healthy weight
• Insulin resistance or type 2 diabetes
• Lack of regular physical activity

When to see a doctor

See a doctor urgently if:

• If you have very heavy bleeding, severe pelvic pain, fainting, or chest pain, call your local emergency number immediately.
• If you have thoughts of harming yourself, get help right away — call your local emergency number or a crisis line.

Book a routine appointment if:

• If you have irregular periods, persistent acne, excess hair growth, or trouble getting pregnant.
• If your symptoms are affecting your mood, confidence, or quality of life.
• If you notice your symptoms are coming and going more intensely and you want to understand why.

Diagnosis

There is no single test. A doctor will take your medical history, ask about symptoms, and may do a physical exam. A PCOS diagnosis is usually made when you have at least two of these three signs: irregular periods, signs of high androgens (from blood tests or symptoms), and polycystic ovaries on an ultrasound.

Tests that may be done

• Blood tests to check hormone levels (such as testosterone) and blood sugar/insulin status
• An ultrasound scan of the ovaries to look for cysts and check their size
• A physical exam to notice signs like acne, extra hair growth, or scalp hair thinning

What to expect at your appointment

The process can happen over multiple visits. You may be referred to a gynecologist, an endocrinologist, or both. Be prepared to talk in detail about your periods and symptoms — this helps get the right care.

Treatment

PCOS cannot be cured, but it can be managed. Treatment depends on your symptoms and whether you want to get pregnant. Lifestyle changes are the foundation of care, and medications are available for period irregularity, androgen excess, insulin resistance, and fertility support.

Self-care at home

• Work toward a healthy weight — losing even 5–10% of your body weight can improve periods and hormone levels.
• Stay active on most days — aim for 30 minutes of activity you enjoy.
• Follow a balanced diet with whole foods, lean protein, and lots of vegetables.
• Practice stress relief, such as deep breathing, yoga, or journaling.
• Prioritise sleep — 7–9 hours a night helps hormone balance.

Medical treatments

Medical approaches may include hormonal contraceptives to regulate cycles and lower androgen symptoms, medicines to lower blood glucose and insulin levels, and specific treatments for acne or excess hair growth. There are also fertility treatments for those trying to conceive. Always make decisions about medications with your doctor or specialist, as benefits and side effects vary from person to person.

When is surgery considered?

Surgery is rarely used for PCOS. A minor keyhole procedure called laparoscopic ovarian drilling may be considered for certain situations, such as persistent anovulation (not releasing eggs) when medicines haven't worked, especially if fertility is a goal.

Living with this condition

Living with PCOS is a daily journey. Some weeks you may hardly notice it; other weeks symptoms may flare up. Tracking your cycle and symptoms in a journal can help you and your doctor see patterns and adjust your plan.

Lifestyle tips

• Find an exercise you love — whether that's walking, swimming, dance, or cycling.
• Set small, realistic health goals instead of aiming for perfection.
• Join an online or in-person PCOS community for shared experiences and tips.
• Give yourself permission to rest and ask for help when you need it.
• Avoid smoking and limit alcohol, as both affect hormones.

Diet and exercise

Eat regular meals that combine lean protein, fibre, healthy fats, and slowly digested carbohydrates (like oats or pulses). Limit sugary drinks and refined snacks. Combine cardio (walking, cycling) with strength training (weights, resistance bands) — this works well for improving insulin sensitivity.

Mental health and emotional wellbeing

PCOS can take a toll on emotional health. Anxiety, depression, body image concerns, and frustration are common. If you're struggling, please talk to your doctor or a counsellor. And if you ever have suicidal thoughts, call your local emergency number or a suicide hotline immediately.

Prevention

There is no known way to prevent PCOS itself, because it is largely hormonal and genetic. However, a healthy lifestyle can reduce the severity of symptoms and lower the risk of long-term complications such as diabetes and heart disease.

Complications

If left untreated

• Type 2 diabetes and insulin resistance
• High blood pressure and high cholesterol
• Sleep apnoea (interrupted breathing during sleep)
• Endometrial cancer (thickening of the womb lining due to missing periods)
• Symptoms such as acne and hair growth that may be more difficult to reverse over time

Long-term outlook

The outlook for PCOS is generally positive with good support. Most people can manage their symptoms, protect their heart and metabolic health, and many find that their periods become more regular with age. If fertility matters to you, there are effective treatments to help. A patient, structured approach works best.
