Abnormal Vaginal Bleeding

Abnormal vaginal bleeding occurs at the wrong time of the month when the women is not supposed to be menstruating. This is the most common cause of abnormal vaginal bleeding during child bearing years.

b) Abnormal menstrual bleeding patterns

The duration, interval and quantity of menstrual discharge may be indicative of the abnormality that is causing the bleeding.

• Hypomenorrhea- when menstrual bleeding is for short duration. A hyperactive thyroid (hyperthyroidsm), certain kidney diseases or oral contraceptives can cause hypomenorrhea Hypermenorrhea-when menstrual bleeding is for long duration
• Polymenorrhea - when the periods occur too frequently. This can be due to pelvic inflammatory disease, endometriosis or sexually transmitted diseases,.Sometimes, the cause is unclear, especially in the case of dysfunctional uterine bleeding.
• Oligomenorrhea - when the menstrual periods are seldom. This can occur when a women is suffering from anorexia, physical and medical stress or when she suffers from Poly Cystsic Ovarian Syndrome (PCOS)
• Metrorrhagia -Is more common in perimenopausal women( on the verge of a menopause) when the duration of the period varies from one cycle to another. This can be due to benign growths in the cervix like polyps or due to uterine infections or birth control pills. Sometimes an identifiable cause will be absent.

• Menorrhagia - When the menstrual bleeding is heavy (> 5 tablespoon blood loss per month)
• Hypomenorrhea - Menstrual bleeding in low volumes
• Spotting especially in between periods. It can be due to:-
• Hormonal birth control pills or patches
• Use of intrauterine devices(IUD)
• Stress
• Medications such as anticoagulant drugs can also cause this condition.

c) Anovulation (lack of ovulation) in a woman is signaled by -

• prolonged bleeding at irregular intervals,
• absence of periods for a long duration
• high estrogen and low progesterone levels in the blood.

This combination places a women at a high risk for developing uterine cancer.
