What You Need to Know About Food Allergies

May 01, 2021

Food allergies are common among many people. Sometimes the effects of consuming such foods can be severe and can land you in an emergency room. However, you don’t have to suffer the agony of such health problems. With home-based or in-office treatments, you can enjoy all your favorite foods without the fear of developing complications.

What Are the Causes of Food Allergies?

People with food allergies have immune systems that treat some proteins as harmful. Your body’s immune system produces an antibody to attack the protein. When you consume food with such a protein, the body’s immune system reacts by producing histamine.

Histamine causes the blood vessels to expand, leading to inflammation and swelling on your skin. Sometimes, histamine might affect the nerves and cause itchiness on your skin.
Some of the common triggers for allergic reactions include:

  • Eggs
  • Fish
  • Milk
  • Groundnuts and peanuts
  • Soybeans
  • Wheat
  • Mutton

Food Allergies Symptoms

When you have been diagnosed with food allergies, you might experience the following symptoms:

  • Rapid fall in blood pressure
  • Itchy and tickly throat
  • Respiratory issues such as shortness of breath and wheezing, which worsen with the progress of the allergic reaction
  • Nausea
  • A feeling of itchiness and rashes on your skin
  • Streaming eyes and nose
  • Vomiting
  • Swelling on the throat, face, and lips
  • Rapid heartbeat
  • A feeling of apprehension
  • Loss of consciousness

When you experience such symptoms, you should consider visiting the physician or emergency room near you.

Diagnosing Food Allergies

When you have an allergic reaction, your doctor at Medical Aesthetics in Menlo Park will carry out a diagnosis to determine the type and source of the allergy. During the diagnosis, the doctor can ask you about your reactions to the food.

The doctor would want to know about the following:

  • Symptoms that occur when you consume the food
  • How long it takes for the onset of your allergic reaction
  • The food that causes the allergic reaction
  • Where you eat the food
  • If the food is cooked or eaten raw

Your doctor might also be interested in other existing allergies such as seasonal ones, family history of allergies, and asthma.

To diagnose food allergies, Dr. Joelle Osias might recommend the following tests:

Skin Prick Test

During the skin prick test, your specialist places diluted foods on your arm and uses a sterile needle to prick the skin. If you have any reactions such as itching, redness, or swelling, you might be allergic to the food. However, the specialist might have to repeat such a test several times to confirm the diagnosis.

Food Diary

Your doctor might recommend you write down every food you eat and the reactions you experience. The doctor will then review your food diary as part of your food allergy diagnosis.

Blood Test

During the test, your doctor will take a sample of your blood and check for antibodies that are specific to certain foods. The presence of such antibodies can indicate a food allergy.

Physician-Supervised Blind Food Challenge

The blinded food challenge is known to be among the most accurate ways of diagnosing food allergies. During the procedure, the doctor will give you a suspected food allergen and monitor you closely for reactions. Such a procedure eliminates the chances of psychological reactions.

Treatment Options

When you visit Foreviva Medical Clinique for food allergies treatment, our doctor will recommend some treatments such as:

Avoiding Causative Foods

The traditional and effective way of treating such health issues is by avoiding the triggering foods to avoid allergies. However, you might also need to avoid inhaling or touching such foods to prevent allergic reactions depending on the nature of your allergic reactions

Oral Immunotherapy

Oral immunotherapy is a new way of preventing food allergies. The treatment option involves administering increased amounts of allergens to increase the threshold of allergic reactions.


For emergency care of allergic reactions, your specialist might recommend medications. In such cases, below are some of the medications that can treat allergic reactions:

  • Antihistamines. Such medications come in the forms of tablets, gels, and liquids. Therefore, when you use such medications, they block the effects of histamine, reducing its effects.
  • Epinephrine. Adrenaline treatments are suitable for people who are at risk of developing anaphylaxis. The epinephrine treatments keep your blood pressure constant by constricting your blood vessels.
