If you develop intestinal gas and other digestive symptoms after you eat boiled eggs, you may have a dietary intolerance to eggs.

Egg intolerance is a condition that causes digestive complications when you ingest eggs. It’s different from an egg allergy.

Egg intolerance occurs due to issues in your digestive system. An egg allergy is an overreaction of the immune system to the proteins in eggs.

Egg allergies also cause more severe symptoms to develop aside from digestive complications.

Egg Intolerance Can Make You Gassy

Egg intolerance occurs if your body can’t digest the proteins found in the yolk of the egg, the white of the egg, or both.

Egg isn’t one of the common intolerances. Common ones involve intolerances to lactose, a sugar in milk; gluten, a protein in wheat; or histamine, a chemical in foods such as cheese, pineapples, and bananas.

After you ingest a food, your small intestine creates enzymes to break down the sugars and proteins in the food. If your body doesn’t produce enough of the right enzyme to digest the proteins in an egg, they remain in your gut.

Alternatively, your gut might be sensitive to certain foods, which can cause uncomfortable digestive symptoms a few hours after eating them.

Other Symptoms of Food Intolerance

The most common symptoms of any food intolerance, including egg, occur within a few hours of consuming the trigger ingredient.

Alongside gas and bloating, symptoms might include:

  • Diarrhea
  • Nausea
  • Heartburn
  • Upset stomach
  • Abdominal pain
  • Headaches or migraine attacks
If you develop severe abdominal pain, unexplained weight loss, or a severe reaction to food, call your doctor right away.

Can You Treat Egg Intolerance?

Egg intolerance doesn’t have a cure, but you can manage it by avoiding egg products as much as you can.

Talk with your doctor, an allergist, or a gastroenterologist about getting a clinical diagnosis. An allergy expert may have you complete a food diary describing your food intake and subsequent symptoms to support diagnosis.

Once you have a diagnosis, you will need to avoid eating eggs and egg by-products. On food labels, eggs may have a different name. For example, the following ingredients all involve egg proteins:

  • Albumin
  • Globulin
  • Lecithin
  • Livetin
  • Lysozyme, which is mostly used in Europe

  • Ovalbumin, ovovitellin, and other words starting with “ovo”
  • Powdered egg
  • Vitellin
Egg is one of nine major food allergens that the U.S. Food and Drug Administration (FDA) requires food producers to clearly disclose on the product label.

Aside from boiled eggs and other forms of directly cooked eggs, they often crop up in the following foods and drinks:

  • Caesar salad dressing
  • Custard
  • French toast
  • Frosting
  • Home-baked goods, especially those with more than two eggs in a recipe
  • Ice cream
  • Mayonnaise
  • Meringue
  • Pancakes
  • Quiche

Read labels carefully before you ingest any food product if eggs make you severely gassy.

Is It an Egg Allergy?

Because many people confuse egg intolerance and egg allergy, it’s best to talk with your doctor about your symptoms.

Severe egg allergies can cause life-threatening reactions. If you develop hives, skin rashes, nasal congestion, or asthma symptoms, like breathlessness and wheezing, along with digestive symptoms after you consume eggs, you most likely have an allergy, not an intolerance.

For people with an egg allergy, even touching or inhaling a minuscule amount of a trigger allergen can cause a severe reaction. For people with an egg intolerance, they would need to eat eggs to experience symptoms.

The Takeaway

  • If you experience gas and bloating after consuming boiled eggs, you might have an egg intolerance.
  • While an egg intolerance doesn’t have a cure, you can manage your symptoms by avoiding eggs and monitoring how they affect your digestion, ideally with guidance from a healthcare provider.
  • Pay attention to food labels for hidden egg ingredients, like lecithin or albumin, if eggs seem to aggravate your symptoms.
  • If severe abdominal pain, unexplained weight loss, or a severe allergic reaction occurs after eating eggs, seek prompt medical attention. You may have an egg allergy rather than intolerance.
