How does your body tell you you’ve been allergic to cats?

How To Know If You are Allergic To Cats? I will point out a few signs that people, who are allergic to cats, often experience. If you have the following symptoms, you may suspect that you are allergic to cats. Symptoms of a cat allergy include:

  • Sneezing
  • Runny, itchy, stuffy nose
  • Itching, red skin
  • Itchy, red eyes
  • Cough
  • Hives or rash on chest and face

And severe symptoms you may experience include:

  • Shortness of breath
  • Chest tightness
  • Wheezing

These symptoms can appear within minutes or hours after contacting cat fur, saliva, or urine.

Symptoms of cat allergy are different from person to person. It depends on the allergen as well as the level of exposure to that type of allergen. For example, you will experience itchy or red eyes if small allergens from cats can get into your eyes. Or when allergens enter your lungs, you may experience shortness of breath, cough, or wheezing because the allergens combine with antibodies and cause these symptoms. A rash on the face, neck, or chest can occur in some people as the body reacts to an allergen. In some cases, allergies to cats can trigger asthma attacks or even chronic asthma.

However, you need to understand that the above symptoms can be manifestations of many other allergies that cats do not cause. So, if you have the above symptoms, it would be best to make an appointment to get checked at an allergist clinic. Doctors will perform tests to determine for sure if you are allergic to cats and give appropriate advice.

Reasons You Can Suddenly Become Allergic to Cats

An allergic reaction is a normal reaction of the body. Allergies occur when the body’s immune system overreacts to harmless substances. In other words, your immune system mistakes a substance as harmful to your body while it is harmless to most people. Allergic reactions begin when our bodies contact a substance through inhalation, ingestion, or direct skin contact. Then, as a normal mechanism, your body will react to destroy what it considers harmful (allergens) by producing immunoglobulin E (IgE) antibodies. These IgE antibodies appear and simultaneously trigger the release of leukotrienes, histamine, and other chemicals that are responsible for allergy symptoms.

Factors that influence the development of allergies can include hormones, family, and environmental factors. Genetics seems to play a role in developing allergies, which means you’re more likely to develop an allergy if your family members also have allergies. In addition, if you are a hypersensitive person or have ever had other allergies, your risk of developing a cat allergy is higher.

Anyone can experience cat allergy symptoms at any time in life. You can develop a cat allergy after spending a long time living with cats. Because in this case, the body has been repeatedly exposed to the allergen. Another reason is that cat allergies take a while to develop from initial exposure.

You suddenly develop a cat allergy due to allergens present in the cat’s fur, saliva, and even urine. These substances contain certain proteins that are responsible for allergic reactions. Many people are sensitive to them. If you are one of those people, you should pay attention because you are also allergic to other cats. If you notice that only your cat is causing your allergy symptoms, you are probably allergic to something else that accidentally got on your cat’s body. Your cat may run around and carry in her fur substances that are likely to cause you allergies.

How to deal with a sudden cat allergy?

How to get rid of cat allergy symptoms naturally? I offer some remedies you can try to ease your symptoms.

  • Medication: In most cases, you’ll be able to control your symptoms with over-the-counter or prescription drugs or to get allergy shots. You can also use saline (which you can make at home) to relieve nasal symptoms such as congestion, runny nose, and sneezing.
