Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. I feel you have gastroenteritis. Most cases of gastroenteritis are caused by viruses and requires only symptomatic treatment. Consuming contaminated foods or drinks is another common cause. You do not need antibiotic and also not anti diarrhoeal agent. I would suggest you to drink plenty of water or electrolyte solutions to prevent dehydration. Add bland foods to your diet such as bananas, toast, oatmeal and rice in small amounts every couple of hours. Avoid spicy food. Restrict meat for few days. You can take curd which will be beneficial. You can take capsule omeprazole 20 mg before breakfast once daily for a week. Probiotics like sporolac or ecobion will be beneficial. In case if your symptoms persist, I would have asked for stool routine examination and based on the report I would have decided on the next line of management (requirement of antibiotic). Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Harish Naik
