Gastrointestinal problems from whey are the result of an allergic reaction to whey protein. Whey protein makes up about 20 percent of cow's milk and is commonly used in protein shakes and other weight-gaining products. A person with a whey allergy may also be allergic to casein, the other 80 percent of milk proteins. If you suspect that you're allergic to whey, make an appointment with an allergist for a proper diagnosis and treatment options.
Whey Allergy
If you're allergic to whey, whenever you consume diary products, your immune system overreacts to the protein as if it was a harmful substance. The immune system fails to recognize the whey as a safe protein and begins to defend the body by creating IgE antibodies to fight off the whey. During this process, various chemicals are produced throughout the body, causing common food allergy symptoms. A whey allergy is mostly common in young children under the age of three years but can affect anyone.
Gastrointestinal Problems
The most common gastrointestinal problems from a whey allergy are nausea, vomiting, diarrhea, gas, bloating, cramping and abdominal pain. You may lose your appetite and feel sick to your stomach until the whey protein is removed from your body. Gastrointestinal problems can lead to excessive weight-loss from vomiting and diarrhea. If you notice blood in your vomit or stools, call your doctor right away.
Other Whey Allergy Symptoms
Gastrointestinal problems from a whey allergy will cause other symptoms to develop alongside digestive complications. Other whey allergy symptoms include skin reactions, asthma and rhinitis. Common skin reactions include hives, general skin irritation and eczema. Skin reactions develop within minutes after ingesting whey and cause the skin to become inflamed and itchy. You may develop wheezing, difficulty breathing and chest tightness. Rhinitis symptoms include nasal congestion, eye irritation, throat itchiness and sneezing.
Treatment
The most effective treatment for a whey allergy is to avoid consuming products that contain whey. Whey may be found in unlikely food products, such as hot dogs, breads and some beverages. Digestive complications from a whey allergy can only be treated by drinking water and waiting for the body to rid itself of the protein. Other whey allergy symptoms may be treated with antihistamines.
Anaphylaxis Consideration
Gastrointestinal problems accompanied with shortness of breath, pale skin, chest pain and dizziness may be a sign of anaphylaxis, a life-threatening allergic reaction. Call 911 if these symptoms develop.
