Hello Doctor, I have been having stomach problems for the last 3 days. Symptoms: - On the first night, I had one episode of completely watery diarrhea. - The next day, I had loose stools twice. - Today, since morning, I have already passed stool 3 times. - I still feel the urge to pass stool even after going. - I have abdominal cramps/stomach pain and acidity. - Yesterday, my stool was slightly greenish, and today it is loose/soft. - I do not have fever, vomiting, or blood in the stool. Food history: - I ate tamarind pickle, spicy food, and food prepared with old refrigerated thecha. - Last night I ate masala brinjal-potato curry, tomato curry, and chapati. Other history: - This type of stomach upset happens about 2 times a month. - If I delay my meals and become very hungry, my acidity becomes worse. - I took Nomepra-D for acidity and one medicine from a local medical store for diarrhea. My questions: 1. Is this likely to be food poisoning, gastroenteritis, IBS, or something
