Treating food poisoning involves resting and avoiding the intake of food and drink for several hours and then taking sips of water or sucking on ice chips, advises Mayo Clinic. As the patient feels better, he can consume bland, low-fat, easily digested foods.
In most cases, food poisoning symptoms alleviate within 48 hours, according to Mayo Clinic. In the meantime, the goal is to keep the individual comfortable and hydrated. Clear sodas and broth, as well as noncaffeinated sports drinks, are good choices for such a person, along with water. Bananas, rice, toast, gelatin and crackers are bland foods that the individual can eat when he feels ready.
A person with food poisoning requires immediate medical attention if symptoms do not improve within three days; if he has severe abdominal pain, prolonged or bloody vomiting, bloody diarrhea or dark stools; or if fever or signs of dehydration are present, states WebMD. A person who becomes dehydrated due to excessive vomiting and diarrhea may require hospitalization, where he can receive intravenous fluids, explains Mayo Clinic. Certain types of bacterial food poisoning and severe symptoms require treatment with intravenous antibiotics. An individual who does not have a fever and who suffers from diarrhea that does not contain blood may benefit from taking medications such as loperamide, which is sold as Imodium A-D, or bismuth subsalicylate, which is Pepto-Bismol. A doctor can approve this treatment option.
