i m a 23 yr old male from tamilnadu,india. height 175 cms ,weight 67 kilogram.for the last 2 yrs i am having constant diarhea once a day,and lost more than 4 kgs of weight..i have no stomach pain and blood in stool but so much of mucus,gas and pain due to gas if i dont eat for longtime. i feel very tired and it looks like my intestines are not taking any energy from food.

i am able to eat any spicyfood ,meat,egg and fish without any discomfort or pain or gas formation..but in the end i have diarhea and no energy taken.

the only time i get pain and excessive gas in my intestine is when i dont eat while i was so hungry. what should i do?
