My digestive system has become very weak. I was hospitalized for food poisoning for two days. Even before that I used to have frequent gas problems. After getting discharge it has been almost 15 days. Now if I take tea then I get gas even having any kind of outside food I starts feeling un easy. I take lan 30 tablet for gas which gives lot of relief.Please tell me a solution so that I can make my digestive system strong and avoid gas problems.
