The most important treatment is to stop eating the food that triggers your allergy. Medical treatment can ease symptoms but will not cure the disease. Typically, antihistamines will relieve the itching, but they are unlikely to prevent allergic symptoms.
What complications can food allergy cause?
Most people with food allergy are able to live a normal life with only a few restrictions in their diet. Complications are rare and include the following:
It becomes harder to get all the nutrients you need, which can lead to associated problems of malnutrition such as anaemia.
The mucous membranes in your mouth and throat may swell and cause difficulty in breathing.
