My age is 28+, I am staying away from home due to job, I am suffering from too much gas, i am taking histac 300 on regular basis because otherwise I will get too much acidity, i have 2 times bowel excretion on regular basis, rarely after bowel excretion it feels like not passed fully, bowel colour is dark brown not black but very dark brown, the main problem is i am passing too much of gas....
