Nausea after eating eggs
Eggs are a rich source of nutrients, making them a popular meal choice and ingredient. However, some people may experience nausea after eating eggs.
If you feel nauseous after eating eggs, you may have an intolerance or allergy to egg yolks, egg whites, or both.
Signs of nausea after eating eggs
Signs of nausea after eating eggs include:
If you have an egg allergy, other symptoms may include:
Causes of nausea after eating eggs
Not all foods agree with everyone. You may find that eggs also cause physical symptoms that make you uncomfortable. These can happen for several reasons, including:
If eating eggs makes you feel nauseous, you may have an egg allergy.
Allergies involve the immune system. With an egg allergy, your body recognizes the proteins as foreign, overreacts and produces antibodies. These create egg allergy symptoms include itching, hives, swelling, wheezing, and difficulty breathing. Sometimes even a small amount can cause a serious reaction.
An intolerance is different from an allergy. Where an allergy is immune-related, an intolerance is digestive-related. This occurs because your body is unable to break down the food. This may be caused by a lack of enzymes, or sensitivity to ingredients like additives or naturally existing chemicals.
An egg intolerance won’t produce antibodies, but it may create digestive symptoms like nausea, vomiting, cramping, pain, and diarrhea. Some people with an egg intolerance may be able to eat small amounts of eggs without experiencing any nausea or other symptoms.
Sensitivity to texture and smell
Some people have highly reactive senses. You may experience nausea or gagging from the smell, texture, or taste of an egg. This may not be related to any allergy, intolerance, or other health condition. You may just not like eggs.
Some conditions, like pregnancy, are naturally prone to nausea. You may be encouraged to eat foods rich in protein to help, but you may find certain foods like eggs can aggravate your nausea.
Nausea can be a side effect of some treatments like chemotherapy. While bland, soft foods like hard-boiled eggs may improve nausea, they also might make it worse for some people.
Tests for nausea after eating eggs
If you experience nausea after eating eggs, your doctor may test for an allergy or intolerance. These tests include:
Your doctor will place a small amount of liquid containing egg onto your forearm. This liquid is then poked into the skin with a probe. If your skin develops raised red bumps within 15 to 20 minutes, you may have an egg allergy.
Your doctor may test your blood for immunoglobulin E (IgE) antibodies to egg protein.
Your doctor may ask you to remove eggs from your diet and then reintroduce them after a time. If you experience nausea or other symptoms after eating eggs again, you may have an allergy or intolerance.
Food sensitivity tests
Sometimes complementary and alternative health practitioners may request food sensitivity tests, but these tests are controversial and not always reliable.
Treatment for nausea after eating eggs
If you have an intolerance, your doctor may suggest eliminating eggs from your diet. If you haven’t seen a doctor and are eliminating eggs on your own, it’s best to speak to an allergist to rule out an egg allergy.
If you have an egg allergy, the best treatment is to avoid all eggs. Inhaling, touching, or eating even a small amount of egg may cause allergic reaction. If you are only allergic to egg whites or yolks, you should avoid eggs all together as there may still be protein present.
There is no cure for a food allergy, but your doctor may recommend treatments to manage symptoms or treat your immune system. These may include:
- Antihistamine medication to reduce mild symptoms, like itching
- Adrenaline medication for emergency anaphylaxis treatment
- Oral immunotherapy, or eating the allergen
- Sublingual immunotherapy, or placing the allergen under the tongue
- Epicutaneous immunotherapy, or placing the allergen on the skin
- Other immunotherapy medications
In immunotherapies, small amounts of egg are given in increasing amounts until you don’t have a reaction. This must be done under the specialized care of an allergist doctor to avoid harm.
A serious reaction to eggs can be life-threatening. Seek medical attention.

Allergies QuizWhat are the causes of allergies? This online quiz challenges your knowledge of common food and household allergens, environmental triggers, allergic diseases and conditions, and allergy symptoms and treatments.
Allergy (Allergies)An allergy refers to a misguided reaction by our immune system in response to bodily contact with certain foreign substances. When these allergens come in contact with the body, it causes the immune system to develop an allergic reaction in people who are allergic to it. It is estimated that 50 million North Americans are affected by allergic conditions. The parts of the body that are prone to react to allergies include the eyes, nose, lungs, skin, and stomach. Common allergic disorders include hay fever, asthma, allergic eyes, allergic eczema, hives, and allergic shock.
Allergy Treatment Begins at HomeAvoiding allergy triggers at home is one of the best ways to prevent allergy symptoms. Controlling temperature, humidity, and ventilation are a few ways to allergy-proof the home. Cleaning, vacuuming, and using HEPA air filters also helps control allergies.

Symptoms and signs of a food allergy reaction include nausea, vomiting, diarrhea, abdominal pain, itching, hives, eczema, asthma, lightheadedness, and anaphylaxis. Allergy skin tests, RAST, and ELISA tests may be used to diagnose a food allergy. Though dietary avoidance may be sufficient treatment for mild allergies, the use of an Epipen may be necessary for severe food allergies.
Hay Fever (Allergic Rhinitis)Hay fever (allergic rhinitis) is an irritation of the nose caused by pollen and is associated with the following allergic symptoms: nasal congestion, runny nose, sneezing, eye and nose itching, and tearing eyes. Avoidance of known allergens is the recommended treatment, but if this is not possible, antihistamines, decongestants, and nasal sprays may help alleviate symptoms.
