What causes irregular periods?

Irregular ovulation: Ovulation is necessary to have normal spontaneous menstrual periods. After ovulation the hormone Progesterone rises; if no pregnancy occurs, Progesterone falls and a period begins. In anovulation there is no Progesterone rise: menstruation cannot occur, so periods are irregular or absent altogether.

Hormonal imbalance: Irregular periods are caused when your body's signals for ovulation and menstruation get confused by hormonal imbalances that can be related to your thyroid (TSH), pituitary (LH/FSH/prolactin), ovaries (estrogen/progesterone). Many external factors can affect the hormones: malnutrition, stress, obesity, for example. Hormonal contraception can help to regulate your periods, which is healthier.

Thyroid problem: Pt with thyroid problem may have irregular periods. You need to seee a doctor to get evaluate the problem for proper treatment.
