Summer triggered post sweating symptoms.

My poop is non consistent, disintegrates into tiny pieces just after hitting water. It doesnt have any shape. I poop just after drinking water ,two times daily.. *If i sweat more,i slightly urge to poop,if i ignored then I feel water gurgling in my stomach if i move,even if i drink more water i feel pressured stomach ,some pain and heavy headed ness,palpitations, and i feel food in my throat always,i feel left abdomen irritation,tightness in left back , Even if drink more water my left upper back feel pressurised, Low amount of urine everytime (had all tests of kidneys from blood ,urine,to Ct scan, no problem of kidneys and its system said by kidney specialist) All these things will only resolve untill i poop Iam having this problem since 5 years Please diagnose me.
