Hi Priya, Welcome to HealthcareMagic Forum.
If your Periods are Irregular it may be due to Hormonal
Imbalance, secondary to PCOS or Hypothyroidism
. Kindly get yourself examined by a Gynecologist to rule out the exact cause. You may want to get a Ultrasound
scan to confirm it.
You are overweight
, you need to exercise regularly and avoid high calorie foods. Go for Brisk walks for 30 to 40 Minutes daily for 5 days a week. Once you start reducing your weight, your Periods may become regular.
Wish you Good Health.
