Hello Doctors, I'm a gastric patient and I'm suffering from it from past 6-7 months now, i was on prescription last month. Though after medications i got better, but from last 3-4 days I'm feeling extremely weak. Like while eating or completing bowel movement i feel extremely weak. The weakness feels as if I'm on drugs. The bloating and burping have again increased, the acid comes out in mouth during night time and have to puke to get better sleep. What could be the reasons for all of this. I'm afraid of colon cancer.
