Hi.. Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand your concerns.. As per your complain it seems that diarrhea and fever are due to infection in stomach and can be due to Viral Gastroenteritis, Food poisoning, parasitic infestation etc.. I would suggest you to consult a Gastroenterologist and get evaluated and a thorough clinical evaluation and investigations like blood tests, stool tests can help in diagnosis and treatment can be advised accordingly.. As of now you can take Loperamide to reduce diarrhea and Tylenol to reduce fever.. Take Fluid Replacement Therapy, drink plenty of water by dissolving oral rehydration salts in it.. Take a semi solid diet and eat more of probiotics like Yoghurt and also add rice, bananas and cereals in diet.. Take home cooked foods and always wash your hands and utensils properly.. In case of bacterial infection antibiotics can be advised.. In case of parasitic infestation anti parasitic drugs like Albendazole can be advised.. Hope this information helps.. Thanks and regards. Dr.Honey Nandwani Arora.
