Amenorrhea
Absence of menstrual periods outside of pregnancy, breastfeeding or menopause — a condition that needs evaluation to protect long-term reproductive and hormonal health.
What is Amenorrhea?
Amenorrhea is the absence of menstrual periods in a woman during her reproductive years, apart from natural causes such as pregnancy, breastfeeding and menopause.
Menstruation is a natural monthly cycle that usually starts around the age of 12 and continues until about 50–51 years. During each cycle, the uterine lining builds up and is shed as menstrual bleeding if pregnancy does not occur.
Women normally do not get their periods during pregnancy, breastfeeding (lactational amenorrhoea) and after menopause. When periods are absent outside of these natural causes, the condition is known as amenorrhea.
Types of Amenorrhea
- Primary Amenorrhea: When a girl does not get her first period by the age of 16 years and has poorly developed secondary sexual characteristics (such as lack of breast development).
- Secondary Amenorrhea: When a woman who previously had regular cycles stops menstruating for about 6 months, without being pregnant, breastfeeding or post-menopausal.
Symptoms of Amenorrhea
Common symptoms and associated signs may include:
- Absence of menstrual periods
- Lack of breast development (in young girls with primary amenorrhea)
- Excess facial or body hair
- Vaginal dryness
- Milky discharge from nipples (galactorrhoea)
Causes of Amenorrhea
The causes differ for primary and secondary amenorrhea and may be physiological (natural) or pathological (disease-related).
Causes of Primary Amenorrhea
- Hereditary: family history of delayed menstruation
- Genetic disorders: such as Turner’s syndrome (girl born with only one X chromosome)
- Congenital abnormalities: such as Müllerian defects (abnormal development of the uterus or reproductive tract)
Causes of Secondary Amenorrhea
Physiological (Natural) causes:
- Pregnancy
- Breastfeeding (lactational amenorrhoea)
- Menopause
Pathological causes:
- Use of some birth control methods (e.g. Depo-Provera injections)
- Stopping oral contraceptive pills
- Stress and depression
- Low body mass index (very low weight or eating disorders)
- Heavy exercise or competitive sports
- Certain psychiatric medications
- Chronic long-term illnesses
- Underactive thyroid (hypothyroidism)
- Scar tissue in the uterus (Asherman’s syndrome)
- Pituitary tumours, especially prolactin-secreting tumours
How is Amenorrhea Diagnosed?
At Maa Nursing Home and NetraJyoti Eyecare Centre, diagnosis of amenorrhea is done through a combination of:
- Physical examination to assess secondary sexual characteristics and any obvious abnormalities
- Detailed medical history, including menstrual pattern, weight changes, medications and stress levels
- Blood tests to check hormone levels (thyroid, prolactin, FSH, LH, oestrogen, etc.)
- Pelvic ultrasound (sonography) to look for structural or anatomical issues in the uterus and ovaries
- X-ray or other imaging if needed to evaluate bone development or related issues
Treatment Options for Amenorrhea
Treatment depends on the underlying cause. Once investigations are complete and an anatomical or hormonal reason is identified, an individualised plan is made.
If no structural abnormality is found, treatment may include:
- Hormone replacement therapy to correct hormonal imbalances
- Medications to treat thyroid, prolactin or other endocrine disorders
- Lifestyle changes such as stress management, adequate rest and reducing excessive exercise
- Proper diet to correct undernutrition, extreme dieting or low BMI
- Moderate exercise regime in case of obesity or sedentary lifestyle
When structural abnormalities (like Müllerian defects or Asherman’s syndrome) are present, surgical correction may be advised to restore normal menstrual function where possible.
Early diagnosis and treatment of amenorrhea helps protect bone health, hormonal balance, fertility and overall wellbeing.
