What allergy can cause swollen lips

There are several diverse types of angioedema, each of which has a diverse cause.

It can be caused by:

  1. an allergic reaction, such as a food allergy – this is known as allergic angioedema
  2. a medicine, such as angiotensin-converting enzyme (ACE) inhibitors for high blood pressure – this is known as drug-induced angioedema
  3. a genetic fault that you inherit from your parents – this is a rare, lifelong condition that usually starts in childhood called hereditary angioedema

But in numerous cases, it’s not clear what causes angioedema.

Cat allergens

Eight cat allergens own been recognized by the World Health Organization/International Union of Immunological Societies (WHO/IUIS) Allergen Nomenclature Sub‐Committee. Fel d 1 is the most prominent cat allergen, accounting for 96% of human cat allergies.[2] The remaining cat allergens are Fel d 2-8, with Fel d 4, an urinary protein, occurring the most in humans among the other seven allergens.

What allergy can cause swollen lips

Every cats produce Fel d 1 including hypoallergenic cats. The main way these allergens are spread is through a cat’s saliva or dander, which gets stuck on clothing. A study found that 63% of people allergic to cats own antibodies against Fel d 4.[3]

Fel d 1

Fel d 1 is the most dominant cat allergen. It is part of the secretoglobulin family, which are proteins found only in mammals. Fel d 1 is primarily secreted through the sebaceous glands and can be found on the skin and fur of a cat.

What allergy can cause swollen lips

It is less commonly secreted through the salivary gland, lacrimal glands, skin and anal glands.[4]

Fel d 4 and Fel d 7

Fel d 4 and Fel d 7 are cat lipocalins. Fel d 4 and Fel d 7 are one of the most common cat allergens after Fel d 1. Fel d 4 is primarily found in cats’ saliva and is associated with atopic dermatitis in children with cat allergies.[4]


4 Causes for Swollen Lips

Allergy

Swollen lipsthat are the result of allergies is a condition known as allergic angiodema.

When your body comes in contact with allergens, it causes a histamine result in your body that causes fluid to build up underneath skin layers.

For mild allergic reactions, an over-the-counter medicine, such as Benadryl, can assist reduce your body’s response to antihistamines.

If skin is only red and swollen, apply a freezing compress. If skin breaks or develops blisters, however, seek medical attention. This is a sign of a third-degree burn and requires medical attention and often antibiotic ointment to heal.

Swollen lip causes aren’t always as cut-and-dried as they appear. Because lip skin is so thin and sensitive, any number of issues could result in that telltale puffy, uncomfortable feeling. Still, as endless as you care for the cause properly, swelling in the lips should be a short-term issue.

Allergies to cats are one of the most common allergies among individuals. Among the eight known cat allergens, the most prominent allergen is secretoglobinFel d 1, and it is produced in the anal glands, salivary glands, and, mainly, in sebaceous glands of cats, and is ubiquitous in the United States, even in households without cats.[1] Allergic symptoms associated with cats include coughing, wheezing, chest tightening, itching, nasal congestion, rash, watering eyes, sneezing, chapped lips, and similar symptoms.

In worst case scenarios, allergies to cats can develop into more life-threatening conditions such as rhinitis and mild to severe forms of asthma.[1] Despite these symptoms, there are numerous types of solutions to mitigate the allergic effects of cats, including medications, vaccines, and home remedies. Hypoallergenic cats are another solution for individuals who desire to pets without the allergic consequences. Furthermore, prospective pet owners can reduce allergic reactions by selecting cats of a specific gender or color, which are associated with a lower production of allergens.
