Why is my skin itchy?

For some people, itchy skin is a constant battle. It can be hard to understand exactly what is causing the skin to itch.

Itchy skin can be the result of a rash or another skin condition. It can also be a symptom of a more serious situation such as liver disease or kidney failure. To get relief, it is significant to identify the problem and treat the underlying reason.


Skin serves a vital purpose as a barrier, protecting the inside of the body. The skin is filled with special cells of the immune system that protect the body and skin from viruses, bacteria, and other hidden threats. Once the skin cells detect any type of suspicious substance, they trigger a reaction that reasons the area to become inflamed. This inflammation is referred to as a rash or dermatitis. This can lead to itching.

The immune cells can act in response to something that touches the skin, a whole-body infection, or an illness. Some rashes are red, painful, and irritated while others can lead to blisters or patches of raw skin. Itching is a symptom that is general to many skin complaints. Skin can itch all over the body or only in specific areas.

Dry skin

Dry skin is one of the most common causes of itchy skin. If people do not see any bright red bumps or notice a sudden change to their skin, dry skin is a likely reason.

Environmental factors that can lead to dry skin contain excessively hot or cold weather with low humidity, as well as washing too much. Dry skin can affect any age group, but, as people age, their skin becomes thinner and drier.

A good moisturizer can generally help to repair dry skin. Extremely dry skin can be a warning sign of dermatitis. People may need to see a dermatologist to help get relief and to keep their situation from getting worse.

Common signs and symptoms of dry skin include:

  • cracks in the skin that are prone to bleeding
  • chapped or cracked skin or lips
  • rough, scaly, or flaking skin throughout the body
  • excessive itching
  • gray, or ashy-looking skin in people with darker skin

It is significant to seek help to treat dry skin because cracks in the skin can allow germs to enter. Once inside the skin, these germs can cause an infection. Red, sore spots on the skin are often an early sign of a potential infection.
