I am 48 years old male. For last few years I had been getting over weight. I am 173 cms tall and weigh 101kg. The weight is mainly on stomach. Now the stomach is so big that size 46 shirts will only fir for me. My chest hands etc are normal. Inspite of no regular drinking for past 2 years the stomach is not reducing. As I have some arthritis heavy joint pains prevent me from normal exercise like walking running etc. I am taking medicine to reduce uric acid. Which little bit over the allowable limit. Now for last 2 years I am not getting proper erection during sexual activity. Kindly help me to attain normalcy. I do not smoke. I have 2 0r 3 peg brandy once or twice a month at weekends. I am a non-veg. I have a borderline bp and cholesterol. Please advise me of how to come out of this situation and lead normal life.
