Do not come to conclusions before medical examination....I would suggest you to consult nearest physician and get it examined clinically based on findings they will guide you further...try to reduce your weight as it is too high...Weight gain happens either due to addition of extra calories or due to failure to spend calories consumed...these extra calories deposited in our body as fat..for weight reduction you have to consume less calories and spend more...avoid junk foods,carbohydrates like rice etc,avoid oily foods...add proteins and fibre rich foods to your diet with green tea,green leafy vegetables, fruits...do regular exercise at least 2 hours a day...good luck.
