Food Allergy Symptoms | Causes & Treatment

Food allergy is a problem that can be quite dangerous for many people. Various types of allergies exist among people. The majority of food allergy problems uncover some simple symptoms. Knowing these can be beneficial for you to take accurate health measures. Food allergy occurs when your immune system reacts after consuming a product.

Food Allergy Symptoms – Overview

Small amounts of food can trigger extreme allergic reactions in your body. It all boils down to the severity of your condition. Some people can also face life-threatening scenarios due to their food allergy. Young children have the maximum risk of suffering food allergy, whereas 3% of adults have developed chronic allergies. Many toddlers end up outgrowing their allergies with age. It is crucial to identify food allergies quickly. Here is how you can look out for the problem. 

Symptoms of Allergies:

Many people suffer from food allergies. These are, however, limited to only a few food items. 

These can be quite terrifying at times. Some of the most common allergies include nut allergies. The majority of people see only mild allergic reactions upon being exposed to these food items. However, a small part of the population can develop life-threatening allergies. The symptoms are visible within a few minutes to 1 hour of consuming the food items. 

There are, namely, two types of allergies. IgE mediated allergies and non-IgE allergies. Some of the most common reactions to IgE allergies are as follows. 

1. Tingling or Itching

Certain food items can result in minor symptoms like tingling or itches. It is a typical immune system response to the food that makes you allergic. If you start having a craving in your hands after eating, the food could stress your immune system. When the entire body starts tingling or itching, then there is certainly something wrong. It would be a good idea to take note of everything you ate. 

2. Rashes

Many people develop random rashes out of the blue. Some have a tough time remembering if they scratched themselves somewhere. The rashes are light to dark red when it comes to food allergies. In some cases, the skin can feel extremely itchy without a rash. Some people even report experiencing eczema. Eczema makes your skin dry, patchy, red, and very sensitive.

3. Swelling

A swollen face, lips, or tongue are other common symptoms of a food allergy. We recommend that you immediately contact your physician to know about your reaction. Swellings showcase that the internal machinery is causing inflammation. The response can be quite harmful in the long run. You can also observe swelling in your throat after eating. The condition is known as angioedema. It is overall helpful in identifying if you have an allergy or not.

4. Shortness of breath

Many people tend to face shortness of breath after eating food they are allergic to in the first place. It can also lead to dizziness and an overall worse off mood. Shortness of breath is a common characteristic of mild food allergies, which are getting worse. It is a good idea to get checked up and know more about your allergic reactions. You might experience wheezing, cough, nasal congestion, among other symptoms.

5. Stomach Problems

Most food items use this option to display their discomfort. Abdominal pain is quite joint for people having a food allergy. You can also experience diarrhea or vomiting in some cases. 

Dehydration can also be a huge problem due to this issue. Many people get it confused with food poisoning. If you are facing stomach problems after eating an individual food item, then visit the doctor. 

What is Anaphylaxis?

Food allergies can lead to life-threatening symptoms. The condition is known as anaphylaxis. When the human body overreacts to a portion of food, it can cause this problem. It is a severe condition and is quite dangerous. People who have severe food allergies can go into an anaphylactic shock. It can be a situation of life and death if they consume even a small amount of food. Many people who have severe peanut allergies can face this problem. In such a situation, it is crucial to have epinephrine or adrenaline to revive the person. Here are the symptoms of anaphylaxis. 

  • The airways can get tight and constricted. It becomes complicated to take a breath. 
  • The throat swells, which makes it feel like there is a lump. Yet again, the breathing is tremendously affected. 
  • Anaphylaxis can lead to a shock with a rapid drop in blood pressure. It can be severely harmful to the heart. 
  • There is a rapid increase in your pulse, which will make the situation worse. 
  • In extreme cases, the person can suffer from a loss in consciousness. 

People who face anaphylaxis need treatment immediately. If it is left as is, then the person can go into a coma or even die. It is crucial to be extremely safe in such situations. 

Non-IgE Allergies:

Non-IgE allergies are different from immune system responses. These are not autoimmune and hence less harmful to the body. The symptoms of this problem can take a lot of time to develop. The immune system makes an immediate impact on the body. Non-IgE allergies will take days or even weeks to show the symptoms. Some common food allergy symptoms in this category are as follows. 

  • Redness or itchiness

It can lead to a minor rash but doesn’t raise the skin. You might end up feeling itchy throughout the day. Overall it is not that severe. In extreme cases, you can face atopic eczema. It is a situation when your skin becomes cracked alongside being itchy and red. 

  • Stomach problems

These connect to other issues instead of food allergies. Stomach problems like diarrhea, vomiting, constipation, abdominal cramps can all occur. These are very random and cover a broad spectrum of other diseases. Thus, it often gets overlooked as a symptom.

Allergy and Intolerance:

Many people confuse allergies with intolerance. Food intolerance is an entirely different subject. It is not at all deadly but can have troublingly similar symptoms. One of the most common prejudices is that of lactose. A minor population of children is allergic to milk, but many kids are lactose intolerant. It can hence be quite tricky to know the difference. An immune response causes one. Whereas the other is due to the absence of helpful bacteria in the body. 

Practise induces Allergies:

Some people might have a destructive lifestyle practice. These can put a strain on the cellular machinery. It can lead to the development of a previously nonexistent allergy. Certain food items can cause severe food allergy symptoms if you consume them and then exercise. Drinking alcohol regularly or taking anti-inflammatory drugs can cause allergic reactions as well.
