Menstrual cycles vary among women, but standards exist for what's normal — helping you know when a disturbance needs medical attention. The ClinicsJo Editorial Team reviews the types, causes, and treatments.
Normal Menstrual Cycle
- Cycle length: 21–35 days (average 28).
- Bleeding duration: 3–7 days.
- Volume: 30–80 ml (5–16 teaspoons).
- Color: red to brown.
- Regularity: consistent timing month to month.
Types of Menstrual Disorders
1. Dysmenorrhea — Painful Periods
Affects 50–90% of women to some degree. Types:
- Primary: no underlying disease, starts in adolescence.
- Secondary: due to a disease (endometriosis, fibroids, pelvic inflammation).
2. Menorrhagia — Heavy Bleeding
Bleeding >80 ml or >7 days, requiring pad changes every hour. Causes:
- Uterine fibroids.
- Hormonal disorders (PCOS, thyroid).
- Clotting disorders.
- Copper IUD use.
- Endometrial cancer (rare).
3. Hypomenorrhea — Light Bleeding
Very light flow. Causes:
- Birth control pills.
- Stress.
- Thyroid disorders.
- Asherman's syndrome (uterine scarring).
4. Oligomenorrhea — Irregular Periods
Cycles >35 days apart. Very common in PCOS, thyroid disorders, and rapid weight loss.
5. Amenorrhea — Absent Periods
- Primary: no period by age 16.
- Secondary: absence for 3 months after previously regular cycles.
Causes: pregnancy (most common), PCOS, severe weight loss, excessive exercise, stress, pituitary tumors, early menopause.
6. Bleeding Between Periods
Causes: birth control pills, IUD, infection, polyps, cervical cancer, ovulation.
When to See a Doctor
- Cycles shorter than 21 days or longer than 35.
- Bleeding >7 days.
- Pad changes every hour for hours.
- Blood clots >2.5 cm.
- Pain unresponsive to painkillers.
- Bleeding between periods.
- Bleeding after intercourse.
- Absent periods for 3 months (with pregnancy excluded).
- Very painful periods disrupting work and study.
- Anemia symptoms (fatigue, pallor, rapid pulse).
Tests
- Pregnancy test (to exclude).
- Hormone tests: FSH, LH, prolactin, TSH, estrogen, progesterone.
- Pelvic ultrasound (transvaginal).
- CBC (for anemia).
- Coagulation studies.
- Hysteroscopy in select cases.
- Endometrial biopsy when cancer is suspected.
Treatment
Primary Dysmenorrhea
- Painkillers: ibuprofen, naproxen, mefenamic acid — start the day before the period.
- Warm compresses on the abdomen.
- Regular exercise.
- Reduce caffeine and salt.
- Yoga and meditation.
- Combined oral contraceptives (reduce pain by 70%).
- Magnesium and vitamin B1.
Menorrhagia
- Iron for anemia.
- Tranexamic acid during the period.
- NSAIDs.
- Combined oral contraceptives.
- Hormonal IUD (Mirena) — reduces bleeding by 90%.
- Endometrial ablation for resistant cases.
- Surgery to remove fibroids.
Irregular Periods
- Treat the underlying cause (PCOS, thyroid disorder).
- Lifestyle modification (healthy weight, exercise, stress reduction).
- Birth control pills to regulate.
Secondary Amenorrhea
- Address the cause: weight control, reducing excessive exercise, stress management.
- Progesterone to induce a period.
- Treat pituitary disorders.
Medical tip: Don't ignore severe pain with every period. Secondary dysmenorrhea can be the first sign of endometriosis, which needs early treatment before it affects fertility.
Endometriosis
Growth of endometrium-like tissue outside the uterus. Symptoms:
- Severe pain with periods, less responsive to painkillers.
- Pain during intercourse.
- Painful urination or bowel movements during periods.
- Delayed pregnancy.
Diagnosis: ultrasound, laparoscopy. Treatment: hormones, laparoscopic surgery.
Natural Tips to Ease Period Symptoms
- Drink ginger or chamomile tea.
- Eat dark chocolate (>70%) in moderation.
- Warm compresses on the lower abdomen and back.
- Light 30-minute daily walks.
- Consistent 7–8 hours of sleep.
- Reduce caffeine and sodium.
- Increase potassium (bananas, dates).
- Warm baths.
- Meditation and breathing exercises.
