Waiting for their condition to get worse is what most people do before going to a doctor. For food poisoning cases, this may prove to be very life threatening. Food poisoning like that of salmonella infection does not really require any specific salmonella treatment. However, if left untreated it may cause serious complications that may become fatal. Emergency management for severe dehydration will probably be done in a hospital. This will include infusion of intravenous fluids. These fluids are directly introduced to your veins. It has a faster absorption rate as compared to taking it in orally. It can also encourage fluids in other parts of your body to temporarily shift to parts that need it the most. Doctors may also recommend using antibiotics, especially if you have compromised immune systems or if the bacteria have migrated into your bloodstream. Anti-diarrheals will also be given to temporarily stop your electrolyte and fluid loss caused by diarrhea.
