Top 3 Signs of An Allergy

People who have a food allergy need always be aware of what they are putting into their bodies. Even the slightest exposure can cause a reaction, so people who are allergic to certain foods need to know all about how common allergens may affect them. They should also know the signs of an allergy to act first if something does go wrong. Richard L. Nass, M.D. , an experienced allergist, can help you with a food allergy.

The first step for people with an allergy is to know the food that they are allergic to. Different foods can cause different reactions, so some may find themselves itching after eating some berries, while others react badly only after consuming shellfish. The second part of knowing what causes an allergic reaction is avoiding exposure as much as possible. To help you identify a food allergy, we have put together some of the vital signs you need to look out for. Read more below.

• Tingling or Itching In the Mouth

One of the most common signs that a person has an allergy to a particular food is if they experience itching or tingling sensations in their mouth. The food is causing swelling on the tongue and within the throat, making it feel like insects are crawling around. It's also possible for this sensation to spread beyond the tongue and throat, leading to itching on the lips, face, or other parts of the body.

People also commonly report tingling sensations in their mouths when they first wake up in the morning. It is usually due to mucus that has built up overnight; it can be caused by food allergies but may occur without any external cause.

• Swollen Lips, Face, or Mouth

Eating food that you are allergic to can lead to your lips, face, or mouth becoming swollen. It may also be accompanied by swelling around the eyes and on other parts of the body. Around 1 in 30 people who have a food allergy will develop anaphylaxis; these severe reactions can lead to trouble breathing or collapse, so it's essential to act quickly.

People sometimes mistake allergic reactions for mild skin irritations or infections, so if you do notice swelling of your face or mouth, then it's worthwhile giving your doctor a call just in case. People prone to allergies may find that their symptoms start mild before progressing to more severe stages.

• Dizziness or Lightheadedness

People with a food allergy often report feeling faint or dizzy after eating certain foods. These symptoms are accompanied by nausea and cramps and a general sense of sickness that leads people to stay in bed for hours at a time. This is one of the most intense signs of an allergic reaction because it can lead to loss of consciousness and even death if it goes untreated.

In summary, you should have the ability to identify a food allergy based on the signs and symptoms you experience. Some of the most common symptoms experienced by people with food allergies include dizziness and lightheadedness, swollen lips, face or mouth, and tingling or itching in the mouth. You should see an allergist as soon as you notice any symptoms before they become more severe.
