Food Allergies and Sensitivities

A food allergy is when the body’s immune system reacts to a food. It can cause hives, itching, and problems breathing. It can also be deadly for some. You will need an emergency epinephrine shot if you have a severe food allergy. You may also be given medicine to ease swelling and itching.

A food sensitivity is when the body has a hard time digesting certain foods. It can cause symptoms such as heartburn or diarrhea. They may make day to day life difficult but are not as serious as allergies. It can be treated by finding what food is causing the problem and avoiding it.

There isn’t strong evidence for natural treatments for this health problem. The best treatment is to remove trigger foods from your diet. Track symptoms and work with a medical team to help find your trigger foods.
