Talk to Dietitian/Nutritionist on Sweating Problem

Hello Doctor. I have a problem from last 4 years my body below head till toe do not sweat in all four seasons. First I did not take it serious but now it is becoming problem for me. My body fats are growing very fast. Due to this I am feeling hungry every time even if I take some food. This issue was started in March 2014 I took bath with water mixed with ALUM. Kindly if any doctor understand this issue and he/she has solution please let me know. Thanks
