Menstrual Disorders

Menstrual disorders are among the commonest gynecological complaints. Normal menstruation occurs at the age of 11-13 yrs. The menstrual cycle is 25–35 days in duration and bleeding lasts an average of 5 days. Total blood flow in a normal cycle is between 25 and 80 ml. Any deviation from the normal cycle is a disorder.

Menstrual disorders type

These are classified here on clinical grounds—

  • Precocious menstruation — menstruation starts before age of 10 yrs
  • Amenorrhoea — the absence of menstruation
  • Oligomenorrhoea — scanty menstruation
  • Dysmenorrhoea — painful menstruation
  • Menorrhagia — Heavy menstruation

Amenorrhoea — menstrual disorders where there is no bleeding. It is of two types.

  1. Physiological.
    During pregnancy and lactation, there is the suppression of menstruation due to hormonal changes leading to physiological amenorrhoea. Then in pre-puberty age, there is no menstruation. Similarly in post-menopausal age, there is amenorrhoea due to reduced hormones.
  2. Pathological.
    It is two types-Primary and Secondary.

Primary amenorrhoea

  • Menstruation does not begin by age of 14
  • Menstruation does not begin by age of 16 in spite of well developed secondary sex characters.

Secondary amenorrhoea

Amenorrhoea of at least 6 months in a previously normally menstruating woman. 


Primary Amenorrhoea

  1. Congenital obstructive defects in the lower genital tract — Non-canalization of cervix, vagina, or Imperforate hymen
  2. Rohitansky-Hauser-Kuster syndrome(congenital absence or gross hypoplasia of uterus)
  3. Congenital aplasia of ovaries(turner’s syndrome)
  4. Intersexual (pseudohermaphroditism)
  5. Hypopituitary dwarfism (empty sella)
  6. Hypothyroid cretinism 
  7. Delayed puberty
  8. Hypothalamic deficiency of GnRH
  9. Organic brain lesions (tumors, infections)
  10. Kallman syndrome

Secondary Amenorrhoea

  • Acquired obstruction in the lower genital tract
  1. Amputation of cervix
  2. Cone biopsy
  3. Trachelorrhaphy
  4. Cauterization
  5. Radiotherapy
  • Uterine factors
  1. Hysterectomy
  2. Destruction of the endometrium (genital tuberculosis, Asherman’s syndrome, intracavity radiotherapy)
  • Ovarian factors
  1. Destruction of ovaries(disease, radiation, oophorectomy)
  2. Ovarian failure (Hypohormonal amenorrhoea)
  3. Hyperhormonal amenorrhoea
  4. PCOD
  5. Premature menopause       
  6. Masculinizing tumours (Arrhenoblastoma, hilus cell tumour, masculinizing luteoma, adrenal-like tumours)
  • Pituitary factors
  1. Psychogenic (anorexia nervosa, pituitary shock, stress, vigorous exercise, pseudocyesis)
  2. Basophil adenoma (Cushing disease)
  3. Acidophil tumors (Gigantism, Acromegaly)
  4. Pituitary failure (Chromophobe adenoma, cysts, Simmonds disease, Sheehan’s syndrome)
  5. Chiari-Frommel syndrome

    • Pituitary fossa
  4. Hysterosalpingography
  5. Vaginal smears

  • Assurance
  • Balanced diet
  • Calm mind
  • Moderate exercise
  • Rest
  • Like all menstrual disorders, here also treating the causative disease cures the amenorrhoea (medically/surgically)
  • Ovulation inducing medicines stimulate ovaries; hence menstruation


Menstrual disorders where menstruation is less. Menstrual periods occur at intervals of greater than 35 days, with only four to nine periods in a year.


Symptoms and Signs

The treatment likewise all menstrual disorders should be done according to the main cause of oligomenorrhea.


  1. Cardiovascular diseases
  2.  Infertility
  3. Osteoporosis
  4. Uterine cancer


It means painful menstruation. This is of two types.

Primary dysmenorrhoea – Pain isn’t caused by a specific condition

Secondary dysmenorrhea – Pain caused by a specific condition, such as endometriosis or fibroids.


Primary dysmenorrhoea — An increase in the amount of prostaglandins (chemicals that contract the muscles of the uterus) in the body.

Secondary dysmenorrhoea –

  1. Endometriosis  
  2. Fibroids or endometrial polyps  
  3. Pelvic inflammatory disease     
  4. Adenomyosis
  5. Early menarche    
  6. Smoking

Symptoms and Signs

  1. Clots are passed in the menstrual blood
  2. Diarrhoea /constipation
  3. Fainting
  4. Gripping pain, constant ache

  • Medicines
  • Surgery, as and when required


Menorrhagia; menstrual disorders with an abnormally heavy and prolonged menstrual period at regular intervals. It is possible to estimate the amount of bleeding by the number of tampons or pads a woman uses during her period.

  • Adenomyosis
  • Intrauterine device (IUD)

Menstrual disorders need great care.
