What counts as a menstrual disorder?
A "normal" cycle varies from woman to woman, but it usually falls between 21 and 35 days, with bleeding lasting up to about 7 days (per ACOG/FIGO). A menstrual disorder is a persistent departure from your usual pattern. The common types include:
| Type | What it looks like |
|---|---|
| Irregular periods (oligomenorrhoea) | Cycles that are unpredictable, shorter than 21 or longer than 35 days, or that vary a lot month to month |
| Absent periods (amenorrhoea) | Periods that stop or never start |
| Heavy periods (menorrhagia) | Soaking through pads or tampons quickly, passing large clots, or bleeding longer than 7 days |
| Painful periods (dysmenorrhoea) | Cramps severe enough to disrupt work, study, or daily life |
| Frequent or infrequent periods | Cycles too close together or far apart |
| Intermenstrual bleeding | Spotting or bleeding between periods |
Occasional variation is normal. It is a persistent or sudden change that is worth evaluating. In Marathi and Hindi, these concerns are described as मासिक पाळीच्या समस्या (menstrual problems) or अनियमित मासिक पाळी (irregular periods) — terms your doctor may use in consultation.
What causes menstrual disorders?
Menstrual problems are usually a symptom of something else, and the underlying cause guides treatment. Common causes include:
- PCOS: A leading cause of irregular or absent periods, often with weight changes, acne, or excess hair. See our PCOS page.
- Thyroid disorders: Both an underactive and an overactive thyroid can disrupt cycles.
- Fibroids and polyps: Benign (non-cancerous) growths in or on the uterus can cause heavy or prolonged bleeding.
- Endometriosis: Tissue similar to the uterine lining growing outside the uterus, a common cause of painful periods. See our endometriosis page.
- Hormonal imbalance: Including the natural fluctuations of puberty, or imbalances affecting ovulation.
- Weight and stress: Being significantly underweight or overweight, intense exercise, or high stress can all alter cycles.
- Perimenopause: As menopause approaches, cycles naturally become less predictable in length and flow.
Often more than one factor is involved, which is why an evaluation looks at the whole picture rather than a single test.
When do irregular periods affect fertility?
Periods are the visible sign of the menstrual cycle, and a regular cycle usually reflects regular ovulation (the monthly release of an egg). When periods are irregular or absent, ovulation may be irregular or not happening — and without ovulation, natural conception cannot occur in a predictable cycle.
This is why menstrual irregularity is often the first clue in a fertility evaluation. The encouraging news is that, when irregular ovulation is the issue, it is frequently treatable — and many women with irregular cycles go on to conceive, sometimes with simple measures and sometimes with assisted treatment. If you are trying to conceive and your cycles are irregular, an evaluation can identify the cause and the right next step.
How are menstrual disorders evaluated?
The aim is to find the cause, not just to control the symptom. Dr. Shweta Agarwal tailors the assessment to your pattern. It typically includes:
History and examination
A detailed look at your cycle pattern, flow, pain, weight history, and any other symptoms.
Pelvic ultrasound
A transvaginal ultrasound examines the uterus and ovaries — identifying fibroids, polyps, ovarian cysts, or the appearance of polycystic ovaries.
Hormonal and thyroid tests
Blood tests for thyroid function, prolactin, and reproductive hormones help pinpoint hormonal causes. See our fertility diagnostics page for the full panel.
Hysteroscopy (when indicated)
Where heavy or abnormal bleeding suggests a polyp or fibroid inside the uterine cavity, a hysteroscopy allows the doctor to look inside the uterus directly and treat some problems in the same procedure.
Not every woman needs every test — the workup is matched to your symptoms.
How are menstrual disorders managed?
Treatment is directed at the underlying cause, and most often begins with the least invasive effective option.
Lifestyle measures
For cycles affected by weight, stress, or exercise, addressing these can restore regularity — sometimes without medication.
Medical management
Depending on the cause, options may include hormonal treatments to regulate cycles, medication to reduce heavy bleeding, or treatment of an underlying condition such as a thyroid disorder or PCOS.
Procedural management
Where a structural cause such as a polyp or fibroid is found, a hysteroscopy or other minimally invasive procedure may be used to treat it.
When fertility is the goal
If irregular cycles are linked to difficulty conceiving, treatment focuses on restoring or assisting ovulation, with options that may include IVF where appropriate. Cost details, including 0% EMI options, are on our IVF cost & EMI page.
When should I see a doctor?
Most menstrual changes are not an emergency, but some warrant prompt attention. Please see a doctor if you have:
- Very heavy bleeding — soaking through a pad or tampon every hour for several hours, or passing large clots.
- Severe period pain that disrupts daily life or is not relieved by usual painkillers.
- A sudden change in your usual pattern, or bleeding between periods.
- Periods that have stopped (when not pregnant) or never started.
- Any bleeding after menopause — this should always be checked promptly.
