Understanding Allergies & Itchy Skin

Allergies are a common problem, affecting up to 30% of the population worldwide. Allergies occur when the body's immune system overreacts to a foreign substance, known as an allergen. Allergens can be found in a variety of sources, including food, pollen, dust, and pet dander.

Itchy skin, also known as pruritus, is a common symptom of allergies. Itching can be mild or severe, and it can occur anywhere on the body. In some cases, itching can be so severe that it can lead to skin irritation, infection, and even scarring.

Causes of Allergies & Itchy Skin

There are a number of different things that can cause allergies and itchy skin. Some of the most common causes include:

• Food allergies are caused by a reaction to a specific food. The most common food allergies are to milk, eggs, peanuts, tree nuts, fish, and shellfish.
• Pollen allergies are caused by a reaction to pollen from trees, grasses, and weeds. Pollen allergies are most common during the spring and summer months.
• Dust allergies are caused by a reaction to dust mites, which are microscopic creatures that live in dust. Dust allergies are most common in homes that are not well-ventilated.
• Pet dander allergies are caused by a reaction to the dander of pets, such as dogs and cats. Pet dander allergies are most common in people who are allergic to cats.

Diagnosis of Allergies & Itchy Skin

If you are experiencing symptoms of allergies or itchy skin, your doctor will likely perform a physical exam and ask you about your medical history. Your doctor may also order one or more of the following tests to help diagnose your condition:

• Skin prick test
• Blood test
• Patch test

A skin prick test involves pricking the skin with a needle that has been coated with a small amount of allergen. If you are allergic to the allergen, you will develop a small, itchy bump at the site of the prick.

A blood test can measure the levels of antibodies in your blood that are specific to certain allergens. If you are allergic to an allergen, your blood test will show elevated levels of antibodies to that allergen.

A patch test involves applying small patches of different allergens to the skin. The patches are left on for 48 hours, and then the skin is examined for any signs of an allergic reaction.

The treatment for allergies and itchy skin will vary depending on the type of allergy and the severity of the reaction. Some of the most common treatments include:
