Hi and welcome to HCM. There are many various reasons that can cause morning diarrhea, but the most common factor that attributes to it is irritable bowel syndrome (IBS). Other simple problems such as stress can also soften the stools in this manner I think you have completed 5 day course of antibiotics and its not necessary to repeat the same. The most accurate, and safe, way to find the cause of morning diarrhea is to schedule a visit with a licensed medical provider and have some tests completed, which will usually consist of lab work and various other tests, including a colonoscopy if needed. Some basic tests will be done first to rule out some of the most common factors, and then more involved ones will be done until the cause of the diarrhea is found. Changes in basic eating patterns will usually effectively solve this IBS problem, whether it is simply eating earlier in the evening or eating healthier. Allergic reactions to specific foods can also cause IBS, so these daily patterns will have to be analyzed until the problem is found, and then changes to remove those problems will have to be implemented. It could also be a simple case of food poisoning not treated fully with antibiotics, anyway its better if u consult a local gastroenterologist if problem persists. In mean time take Tab Oflox OZ 1-0-1 after food for 5 days, continue becelac forte for 5 more days. drink lot of water, avoid spicy food Regards Dr Santosh
