Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. Diarrhea usually caused by acute viral/ bacterial gastroenteritis or irritable bowel syndrome or food poisoning or infections or lactose intolerance or malobsorption syndromes etc Until examination is done it is difficult to say what it is. Avoid spicy food and alcohol avoid smoking and caffeine drinks. Use tablet Pantoprazole before breakfast for one week. Use probiotic tablet twice a day for five days. Drink plenty of liquids and ORS solution. If symptoms not improved please consult your doctor he will examine and treat you accordingly. Hope I have answered your query. Let me know if I can assist you further.
