Irregular Periods: Causes, When to Worry, and Who to See

Most women know their cycle isn't always perfectly predictable. But when periods become consistently irregular - too early, too late, too heavy, or missing altogether - it's your body signalling that something needs attention.

What Are Irregular Periods?

A normal menstrual cycle ranges from 21 to 35 days. Periods are considered irregular when:

• The cycle length varies by more than 7–9 days each month
• Periods are consistently absent for 3 or more months (amenorrhoea)
• Bleeding is excessively heavy or extremely light
• Periods last longer than 7 days

Common Causes of Irregular Periods

Hormonal Causes

• PCOS/PCOD - the most common hormonal cause in Indian women
• Thyroid disorders - both hypothyroidism and hyperthyroidism affect the cycle
• Hyperprolactinaemia - elevated prolactin levels disrupt ovulation
• Perimenopause - hormonal fluctuations in women approaching 40s–50s

Lifestyle Causes

• Extreme weight loss or gain
• Over-exercising or under-eating
• High levels of stress
• Irregular sleep patterns

Medical Causes

• Endometriosis
• Uterine fibroids or polyps
• Pelvic inflammatory disease (PID)
• Certain medications (antipsychotics, steroids)

When Should You Be Concerned?

Consult a doctor if:

• Your periods have been irregular for 3 or more consecutive months
• You have severe pain alongside irregular bleeding
• You're trying to conceive and periods are unpredictable
• You notice unusual discharge, fever, or pelvic pain
• Your periods have stopped before age 45

What Will the Doctor Do?

A menstrual disorder specialist will typically:

1. Take a detailed menstrual and medical history
2. Order blood tests (thyroid, prolactin, FSH, LH, AMH)
3. Recommend a pelvic ultrasound
4. Diagnose the underlying cause and recommend treatment

Treatment may include lifestyle changes, hormonal therapy, or medication depending on the diagnosis.

FAQs

Q1. Is it normal to have irregular periods occasionally? Occasional variation (a few days) is normal. Consistent irregularity over 3+ months warrants medical evaluation.

Q2. Can stress cause irregular periods? Yes. High stress raises cortisol levels, which can interfere with the hormones that regulate your cycle.

Q3. Do irregular periods mean I can't get pregnant? Not necessarily. However, irregular periods can indicate irregular ovulation, which may make conception harder. Consult a specialist.

Q4. Can irregular periods be treated without medication? In many cases — especially lifestyle-related irregularity - diet, exercise, and stress management can restore a regular cycle. Medical treatment is needed for hormonal disorders.

Q5. At what age do periods naturally become irregular? Perimenopause, typically starting in the mid-40s, causes natural cycle irregularity. If irregularity starts before 40, consult a gynaecologist.
