Irregular Periods Treatment — Causes, PCOS and Treatment Pakistan

What Is a Normal Menstrual Cycle?

A normal menstrual cycle is 21 to 35 days (average 28 days). Bleeding lasts 3–7 days with a total blood loss of 30–80 ml. Periods are considered "irregular" if they vary by more than 7 days from month to month.

Common Causes of Irregular Periods

1. PCOS (Polycystic Ovary Syndrome)

Extremely common in Pakistan — affecting approximately 1 in 5 women. Key symptoms:

• Late or skipped periods
• Facial hair (chin, upper lip)
• Acne
• Weight gain, especially around the abdomen
• Hair loss on the scalp
• Difficulty conceiving

2. Thyroid Disorders

Hypothyroidism (underactive thyroid) makes periods heavier and more frequent. Hyperthyroidism (overactive thyroid) makes them lighter and irregular. A TSH blood test is essential.

3. Body Weight

• Excess weight — periods may be skipped or very heavy
• Very low weight or crash dieting — periods can stop entirely
• Healthy BMI is 18.5–25

4. Stress

High cortisol levels suppress GnRH (the hormone that triggers the menstrual cycle). Academic stress, family problems, and work pressure all have an impact.

5. Pregnancy

A pregnancy test is always the first step when a period is missed — even if you believe it is unlikely.

6. Breastfeeding

It is normal for periods to be absent or infrequent for up to 6 months postpartum (lactational amenorrhoea).

7. Perimenopause

Irregular periods can begin in the 40s — this marks the beginning of the transition to menopause.

8. Medications

• Starting or stopping contraceptive pills
• Corticosteroids
• Antipsychotic medications
• Chemotherapy

9. Uterine Fibroids or Polyps

A common cause of heavy and prolonged bleeding.

Natural Ways to Regularise Periods

1. Healthy Body Weight

The single most important factor. A 5–10% reduction in body weight significantly improves PCOS-related irregular periods.

2. Anti-Inflammatory Diet

• Whole grains (wholemeal flour, oats)
• Fruits and vegetables
• Lentils, eggs, fish
• Avoid: refined sugar, white bread, fast food

3. Regular Exercise

30 minutes of walking or yoga daily. Note: excessively intense exercise can cause periods to stop (athlete amenorrhoea).

4. Stress Management

Prayer, meditation, deep breathing exercises, hobbies. Aim for 7–8 hours of sleep per night.

5. Iron-Rich Foods

Anaemia is common from menstrual blood loss — eat spinach, meat, dates, and figs. Consuming vitamin C alongside iron-rich foods increases absorption.

6. Specific Foods

• Cinnamon (dalchini): Studies suggest it helps with cycle regularity in PCOS
• Ginger tea: Helps with cramps and regularity
• Fenugreek (methi): Improves insulin sensitivity, beneficial in PCOS
• Spearmint tea: May reduce hirsutism in PCOS
• Pineapple, papaya: Traditional belief that they induce periods — actually contain mild bromelain

Medical Treatments

1. Combined Oral Contraceptive Pills

The most common treatment. They regulate the cycle and also reduce acne and facial hair growth. Common brands in Pakistan include Yasmin, Diane-35, and Nordette.

2. Metformin (for PCOS)

Addresses insulin resistance in PCOS and helps regularise the cycle. Also assists with weight loss. Available on doctor's prescription.

3. Progesterone

Norethisterone (Primolut N) — used to induce a period or regulate the cycle. Typically prescribed as a 5–10 day course.

4. Thyroid Medication

If the TSH is abnormal — Eltroxin (thyroxine) will normalise periods once thyroid levels are corrected.

5. Fertility Treatments

For women trying to conceive: Letrozole or Clomiphene, prescribed by a fertility specialist.

Treatment for Heavy Periods

If you need to change a pad or cloth every 1–2 hours or bleeding lasts 7+ days:

• Iron supplements (to prevent anaemia)
• Tranexamic acid (Cyklokapron) — reduces blood loss
• Combined oral contraceptive pills
• Mirena IUD — very effective for heavy bleeding
• Surgical options if fibroids are present

Painful Periods (Dysmenorrhoea)

• Ibuprofen (Brufen) 400 mg or Mefenamic acid (Ponstan) 250 mg — start one day before the period is expected
• Heat pad on the lower abdomen
• Warm bath
• Combined oral contraceptive pills for severe cases
• Rule out endometriosis in cases of severe pain

Delaying a Period (for Travel or Weddings)

Norethisterone (Primolut N) — start 3 days before the expected period and continue as needed, then stop. A period will arrive within 2–3 days. Only use after doctor consultation — not appropriate in all situations.

Important Tests

A gynaecologist will typically arrange:

• Pregnancy test
• Pelvic ultrasound (to check for cysts, fibroids)
• TSH (thyroid)
• FSH, LH, prolactin
• Testosterone, DHEA-S (for PCOS)
• HbA1c (insulin resistance in PCOS)
• CBC (to check for anaemia)

When to See a Doctor Urgently

• 3+ missed periods
• Soaking a pad in less than 2 hours
• Large blood clots
• Bleeding for 7+ days
• Cycle shorter than 21 days
• Bleeding between periods
• Bleeding after intercourse
• Severe pelvic pain
• Bleeding during pregnancy
• Fainting during periods

Conclusion

Irregular periods are not merely a cosmetic issue — they signal hormonal and health imbalances. Untreated PCOS carries long-term risks of diabetes and heart disease. In Pakistan, the topic is often considered taboo, but consulting a gynaecologist is essential. Female doctors are available on Ilaaj AI — private consultations in English, from home.
