Hi, There can be several reasons for your recurrent episodes of diarrhea. Definitely, in your case the most common may be because of the outside food you are consuming( commonly called as traveller s diarrhea). It can be due to infections in the intestine (enteritis- bacterial, viral or protozoal) or sometimes stress, hormonal disturbances (esp thyroid) or even diabetes (increased sugar levels). Diarrhea is also common after gastric sleeve surgery. I feel first of all focus on your diet. Take bland diet with lots of fruits and vegetables and plenty of fluids (ORS). Avoid taking spicy or oily food. Take small frequent meals. If still the symptoms persist then go for some investigations like complete blood count, sugar levels, sodium potassium, TSH and stool examination and ultrasound abdomen. This will help us to reach a proper diagnosis and plan further treatment. Take care. Hope I have answered your question. Let me know if I can assist you further.
