Symptoms of food allergies, treatments for food allergies

Food allergies are very common in life. Many people with allergies are prone to allergic reactions when they eat irritating foods. So, what are the symptoms of food allergies?

Symptoms of food allergies:

Without knowing the exact allergen, patients often develop rashes, swelling, throat tightness, and even fainting for “no reason”.

After ingesting allergens, patients feel numbness in the mouth and itching in the throat, which is the mildest symptom; severe cases will develop rashes and swollen skin all over the body; the most serious cases can cause anaphylactic shock, acute asthma, laryngeal edema and other reactions that can be fatal.

Ways to treat food allergies:

Food allergies cannot currently be treated with desensitization. The purpose of checking allergens is first to let patients know which foods they should avoid, which is the most important way to prevent anaphylactic shock. In addition, it has been found that there is a cross-over phenomenon between pollen and fruit allergies. For example, people who are allergic to birch pollen may be allergic to apples, and people who are allergic to wormwood may be allergic to peaches or other fruits. Finding an allergen can help patients avoid related dangers. In addition, there is cross-allergy between food allergens. For example, people who are allergic to food A will be allergic to food B after a period of time. Some food allergies can get better after a period of time. Therefore, not only should allergens be checked at the time of diagnosis, but they should also be rechecked every 1 to 2 years after diagnosis to understand whether the allergens have changed, so as to better avoid risks.
