PCOS Long-Term: Managing Metabolic Risk and Protecting the Endometrium
The short answer: PCOS (often called PCOD in India) is a long-term hormone condition. Over the years, the two things that matter most are keeping the womb lining (endometrium) healthy and keeping weight and blood sugar in check. When periods are very infrequent, the lining is not shed regularly and can slowly build up. A simple plan protects it: a period (natural or brought on by treatment) at least about 4 times a year, using tablets, the pill or a hormone-releasing coil if needed; healthy weight and regular activity; and a check-up if bleeding becomes very heavy or irregular, or if there is any bleeding after menopause. Most women with PCOS never develop womb cancer. In Hindi people often search PCOS ke nuksan (पीसीओएस के नुकसान).
PCOS is a lifelong condition whose manifestations evolve with age. The acne and irregular periods that dominate in the teenage years give way to fertility concerns in the twenties and thirties, and then to metabolic and endometrial cancer risk in the forties and beyond. Effective long-term management requires a proactive, multi-system approach rather than treating each symptom in isolation. For the basics of symptoms, tests and treatment, see our page on understanding PCOS.
Protecting the Endometrium
The most important gynaecological priority for women with PCOS is ensuring that the endometrium (womb lining) sheds regularly. The target is at least 4 bleeds per year (natural or brought on by treatment) in women not using hormonal contraception. Options include:
- Combined oral contraceptive pill — regulates cycles, reduces androgens, and provides reliable endometrial protection; first-line in women not trying to conceive
- Cyclical progestogen (progesterone tablets) — medroxyprogesterone acetate or norethisterone given for 12–14 days every 1–3 months to induce a withdrawal bleed; useful for women who cannot use oestrogen-containing contraception
- Levonorgestrel IUS (a hormone-releasing coil placed in the womb) — provides continuous endometrial protection; suitable for women with PCOS who also have heavy bleeding
Managing Insulin Resistance
Insulin resistance underlies a significant proportion of PCOS pathophysiology. Elevated insulin drives androgen production from the ovaries and promotes endometrial proliferation. Addressing insulin resistance:
- Weight loss of 5–10% of body weight in overweight women significantly improves ovulation and metabolic markers
- Regular aerobic exercise (150 min/week) improves insulin sensitivity independently of weight loss
- Metformin reduces insulin resistance and modestly improves ovulation; used particularly when lifestyle measures are insufficient or when fertility treatment is planned
When to Seek Oncological Assessment
See your gynaecologist, and if needed a gynaecological oncologist, if you have any of the following: periods that stay absent for more than 3–4 months without treatment; very heavy, prolonged or irregular bleeding, especially in your 40s or around menopause; a thick or unusual-looking womb lining on an ultrasound scan; endometrial hyperplasia (an overgrown womb lining) found on a biopsy, particularly atypical hyperplasia; or any bleeding after menopause, even once (see bleeding after menopause). Routine biopsies are not needed for women with PCOS who have none of these.
Atypical endometrial hyperplasia needs specialist care because in some women a small cancer is already present alongside it. It is usually treated with a hysterectomy. Women who still hope to become pregnant may, in selected cases, have hormone treatment instead, with a repeat biopsy about every 3 months. Before such an appointment, our checklist on preparing for a specialist appointment lists the reports worth bringing. Our page on endometrial hyperplasia explains the difference between hyperplasia with and without atypia.
