Irregular Periods: Clinical Meaning

Endometriosis

Endometriosis is a condition where tissue similar to the uterine lining grows outside the uterus. It causes chronic pelvic pain, especially during menstruation, and can lead to infertility. It affects approximately 10% of reproductive-age women.

PCOS (Polycystic Ovary Syndrome)

Polycystic ovary syndrome (PCOS) is a hormonal disorder common among women of reproductive age, causing irregular periods, excess androgen levels, and polycystic ovaries. It is associated with insulin resistance and increased risk of diabetes and heart disease.

Pituitary Adenoma

Pituitary adenomas are benign tumors of the pituitary gland that can cause hormonal excess (functioning) or compressive symptoms (headache, visual field defects). Prolactinomas are the most common type; treatment includes medication, surgery, or radiation.

Ovarian Cysts

Ovarian cysts are fluid-filled sacs on or in the ovary, most of which are benign and resolve spontaneously. Symptomatic cysts cause pelvic pain, bloating, and pressure; large or persistent cysts may require surgical evaluation.

Premature Ovarian Insufficiency

Premature ovarian insufficiency (POI) is loss of normal ovarian function before age 40, causing infertility, irregular or absent periods, hot flashes, and accelerated bone loss. Hormone replacement therapy is recommended until the natural age of menopause.

Cervical Dysplasia

Cervical dysplasia refers to precancerous changes in cervical cells detected on Pap smear, classified as CIN 1, 2, or 3 based on severity. HPV vaccination prevents most cases; LLETZ (loop excision) treats high-grade lesions.
