How to diagnose Food poisoning

For diagnosis, the doctor reviews the symptoms, examines the patient and suggests laboratory testing of a sample of stools and the suspected food if available. A very important symptom for diagnosing it is that all the people who ate the same food get infected. In such cases, a careful analysis of food, to correlate symptoms to the food items consumed by those affected and those unaffected helps to pinpoint the most likely item which might have been infected.

What is the treatment of Food poisoning?

One usually recovers from the most common types of food poisoning within a couple of days. The goal is to feel better and avoid dehydration. The treatment is mostly supportive i.e. treatment of dehydration and replacing salts. Some patients may need treatment of symptoms like drugs to treat vomiting. Occasionally antibiotics may be required if the organisms are demonstrated on laboratory examination; however most of the time these are not required because patients improve soon after initiation of supportive measures.Self-care measures include drinking clean or boiled water with some salt and sugar at frequent intervals. It is important to drink water often to prevent the patient from getting dehydrated because of diarrhoea and vomiting. If there is diarrhoea and the patient is unable to drink fluids (for example, due to nausea or vomiting), he may need medical attention and intravenous fluids. This is especially true for young children.

What are the prevention?

The following points should be considered to prevent food poisoning: Drinking water should be clean and safe. Food should be kept covered while stored to avoid flies and insects from sitting on it. Buying food from roadside vendors should be avoided. Fruits and vegetables should be washed properly before eating. Food should be cooked properly. Do not use outdated foods, packaged food with a broken seal, or cans that are bulging or have a dent. Do not use foods that have an unusual odor or a spoiled taste.

What are the complications?

While most foodborne illnesses can be cured with medicines prescribed or plenty of rest combined with proper hydration, complications can occur during the healing process. A person suffering from foodborne illness is likely to experience some serious health complications. Some of the most common complications are kidney failure, arthrities, nerve damage, anemia, IBS and lactose intolerance. 

What are the dietary and lifestyle advice?

A person suffering from food poisoning needs to take extra care of the diet. Since it is a foodborne disease, one needs to be very mindful of what one eats as it has a deep impact on the effect of medical treatment. Food poisoning patients need to drink lots of fluids to avoid dehydration. Besides this, the patient needs to eat bland foods like honey, bananas, egg whites, oatmeal, rice, peanut butter, mashed potatoes, etc.
