Is This an Emergency?

If you are experiencing serious medical symptoms, seek emergency treatment immediately.

Dairy Allergy

A dairy allergy is considered one of the most common food-related allergies, according to Kids Health 4. A dairy allergy occurs when the immune system fails to recognize the proteins in milk as safe 24. The immune system quickly begins to defend the body by producing antibodies and histamine. Many chemical reactions then cascade, leading to common food-related allergy symptoms. Chest congestion is a common symptom related to a milk allergy 24.

If you experience significant chest congestion after consuming dairy products, you are most likely experiencing an allergic asthma attack 1. Allergy-induced asthma is very common among people who suffer from asthma. About 50 percent of asthma sufferers experience allergic asthma, according to the Asthma and Allergy Foundation of America 3. During an allergic asthma attack, increased levels of histamine cause lung tissue to swell and become inflamed 3. The airways become restricted and the ability to breathe normally is reduced.


Wheezing is a high-pitched sound caused by air being forced through the small opening of the swollen top of the airway. Allergic asthma attacks after consuming dairy products can lead to more serious complications, and suffers need to be evaluated by a medical doctor as soon as possible.
