Welcome to HealthcareMagic. It is very rare for menstrual cycles to become irregular even 1 year after the cesarean section. Usually after lactational amenorrhea
, it comes back to normal and regularized after the first two cycles. The cause of irregular periods
could be due to hormonal imbalance, stress, chronic illness, polycystic ovarian disease
, breast feeding, thyroid gland disorders or diseases, pituitary gland
tumors or cyst, galactorrhea, prolactinomas etc. You should consult a gynecologist and get examined and investigated as soon as possible to know the exact cause of all these episodes.
Hope it helps you. Regards.
