Hello doctor, I am 35 years old and my weight is 75 kg, my height is 175cms. One and half year back I have taken my master health checkup and the result shows normal for all test. Many of my friends and relatives who see me after a long time and ask me" you become very lean. Why like this! are you in diet doing any exercises. I don't know why, I am maintaining the same weight since 10 years. My doubt with me is, I smoke 4-6 cigarette one day. Also I use tobacco pouch not continuously. I stop for 2-3 weeks sometimes and again I use for 1-2 months. I like to know is this the side effect of such usage? I want to stop this habits completely. I have this habit nearly 9-10 years, but I use as I said above, I don't use liquor. I like to know my health condition and I need to stop all completely, please give me some permanent solution for this. Thank you.
