Sudden Weight Gain With Irregular Period And Extended Belly. Is This A Serious Problem?
Thanks for posting your query.
The kind of sudden weight gain at belly with menstruation abnormality is alarming development.
It can be just out of change in feeding behaviour, particularly if you are not keeping a watch on intake and choosing healthy food intake.
Another important possibility at your age is climacteric and impending menopause and hormonal changes which also cause drastic changes in the body homeostasis leading to weight gain.
Third possibility is of some cause within the abdomen eg. some tumor that can make excess fluid in abdomen.
The most important suggestion is to get yourself assessed and a physical examination by a physician of your locality.
Prior to consult please get an ultrasound of abdomen and Complete blood counts, ESR, serum FSH levels and a Pap smear if you did not have had it earlier and review with these reports.
The cause of weight gain needs to be ascertained as soon as possible.
