I usually suffers from constipation and gas. I took more than 20 minutes to release morning stool. The behavior of my digestive system is very erratic. It becomes unstable with a little heavy food and sometimes it doesn't get disturb even when I consume heavy diet in continuations. But most of the time, I suffer from stomach disorder. My stool test found ok but vitamin B12 found a bit less than specification for which I used vitamin tablets for three months. It was good for sometimes after taking medicines but again I am suffering. I do not have any issue with my hunger and diet. Please advice me.
