Allergic symptoms from soy and whey proteins are similar, but can range in severity depending on the individual. Allergic symptoms will develop in the digestive system, the respiratory system, the skin and the cardiovascular system and need to be evaluated and monitored by a medical doctor. Soy and whey are common food allergens, according to MedlinePlus. Whey is one of the proteins that is found in diary products and is commonly used in protein shakes and bars. Discuss your symptoms with your physician before treating them.
Soy and Whey Allergy
Soy and whey allergies are caused by a hypersensitivity of the immune system. When you ingest soy or milk, your immune system reacts to the proteins found in the foods or beverages as if they are dangerous. The body begins to defend itself by creating immunoglobulin E, or IgE, antibodies that attempt to fight off the proteins, according to MayoClinic.com. During this reaction, the body produces other chemicals to help fight off the substances, which leads to common allergic symptoms of soy and whey.
Digestive System Symptoms
Your digestive system will become inflamed and irritated within a few minutes of eating soy or whey, which will cause common symptoms. These symptoms are the same for both allergic conditions and include: nausea, diarrhea, vomiting, stomach pain and cramping. Vomiting and diarrhea can cause you to loose excessive amounts of water and salts that can cause dehydration. If you develop these symptoms, drink more fluids and inform your doctor of your reaction.
Respiratory System Symptoms
Symptoms related to the respiratory system are typically obvious. You may develop nasal congestion and asthma-like symptoms, according to Kids Health. Nasal congestion will cause your sinus cavity to become inflamed, cutting off your normal ability to breathe and drain mucus from your nose. This can lead to sinus pressure and headaches. Asthma-like symptoms include chest tightness, difficulty breathing, wheezing, coughing and shortness of breath.
Skin and Cardiovascular Symptoms
The skin can react to soy and whey by becoming inflamed and itchy. Common skin rashes associated with these allergies are eczema and hives, although you can develop a general itching or tingling anywhere on your body. If you cardiovascular system is affected, you may feel dizzy or lightheaded, which may be a sign of anaphylactic shock, according to MayoClinic.com. Anaphylactic shock is a rare, but deadly severe allergic reaction that will require emergency medical attention.
