Hi,
Welcome to ehealthforum,
Missing periods for more than 6 months could indicate menopausal onset in your age group (absence of periods for more than 6 months with previous history of regular periods). Other possibilities include: obesity, increased body fat percentage, brain or pituitary tumors, PCOS, premature ovarian failure, thyroid dysfunction, use of certain medications, previous D&C, hormonal imbalances, genetic problems, etc. You should consider visiting your doctor/gynecologist for further evaluation to look for the underlying cause for your absent periods. Treatment as appropriate (based on examination findings and investigations results) would be started to help you. Be in regular monitoring and follow-up with your treating doctor/gynecologist and report any new/abnormal symptoms immediately. Take adequate rest. Drink plenty of water. Maintain healthy diet and lifestyle.
Take care.
