gaining weight and eating very little

for the last month and a half I have been gaining a lot of weight and eating very litte. I weight only 120 and now I am up to 132. I am only 5 feet tall. this is really starting to bother me. I just wanted to know why this is happening. I am 51 years old and have never weight this much. I have only weight between 115-120 and never apast 120. please let me know what you think I should to.

Try excercising and eat more but helthier. Eat fish and vegetables. Read what we have written i web4health.info about dieting.
