I had problem of piles from last 2 years and since then I have been losing weight continuously. Though I have gone through the treatment and got rid of the problem, but still I am losing weight. I had thought that after the treatment I would be able to gain weight again but instead I am constantly losing it. I was around 62 kgs and now my weight has come down to 53 kgs. Can there be any other reason behind this? Should I go for a full body check up and see what's wrong? Or just consult a GP?
