Treatment of Food poisoning

Before undergoing treatment for food poisoning, proper diagnosis is carried out to confirm if the person has food poisoning or not. The doctor at first looks at the illness history of a person, types of food consumed in the last few days, and also a physical examination is done to check if there are signs of dehydration or not.

A couple of tests are also done like a blood test, stool culture to observe and examine for the presence of the parasite. For a few people, the condition may improve within a few days while others may take time.

Some of the treatment methods of food poisoning are-

  • Antibiotics

At times doctor prescribes antibiotics to prevent further damage to the system due to food poisoning. For pregnant women, antibiotics are not recommended as they can affect the baby.

  • Replacement of lost fluids

Minerals like sodium, calcium, and potassium are fed to a food poisoned patient in fluid form and electrolytes. These minerals help to maintain the balance of the fluids in the body and also treat dehydration.

Elderly people may switch to drink oral rehydration solutions like infalyte, naturalyte, ceralyte and pedialyte that contain glucose and electrolytes that will help to provide relief from the complications such as excess vomiting, severe dehydration etc.

For infants and children below the age of 5 years should be given to drink breast milk. Discuss with your doctor before offering any form of electrolyte to your child/infant.

Home remedies for Food poisoning

There are a handful of home remedies that can effectively provide relief from a food poisoning or in some condition it can get cure too with a day. Try to keep yourself dehydrated as much as possible and follow a very mild diet so that your stomach system settles down fast from the already infected food.
