Hello, thanks for the query to H.C.M.
Mebeverine the drug which you are taking is just for symptomatic relief.
i
Its side effects are dryness of mouth,
dizziness , some anxiety.
You can take it till improvement.
As far as concerned about the 2 nd query that I B S is a good sign of health.
You are in dilemma , mind it this is a disease and not a good sign , please remove any misconception from your brain.
I B S is characterized by
chronic abdominal pain, uneasiness,bloating and alteration of bowel habits (
diarrhea or
constipation may predominate or they may alternate.)
I don't know, why are you talking that it is a good sign of health.
So consult a doctor and now a days a intestine antibiotic is available so please have it for permanent cure. Get in U/S Abdomen and blood examination, stool.
Regards.
Dr. HET
