Symptom 2. Swelling of the Lips, Tongue, and Throat
Swelling, also known as angioedema, is another common symptom of dairy allergies. This can manifest as swelling of the lips, tongue, or throat, causing discomfort and, in severe cases, difficulty breathing.
The cause of angioedema is similar to that of hives, with the immune system releasing histamine in response to allergens. This chemical can cause blood vessels to dilate, leading to increased fluid accumulation and swelling in affected areas.
Swelling can be alarming, especially when it affects the face and airways. In some cases, the swelling may be severe enough to cause difficulty breathing, a potentially life-threatening condition known as anaphylaxis.
To manage swelling caused by a dairy allergy, avoiding the allergen is crucial. Over-the-counter antihistamines may help reduce swelling, but in severe cases, immediate medical attention is required. If you experience difficulty breathing, seek emergency care as soon as possible. (2)
