What are the common causes of skin inflammation?

There are many potential causes of skin inflammation. Among the most common are allergies, eczema and contact dermatitis. A person can also develop swelling of the skin due to a bacterial infection called cellulitis. In many cases, the swelling of the skin is not dangerous. However, severe skin swelling and swelling caused by a serious infection can be life-threatening.

Allergies are among the common causes of skin inflammation. When a person has an allergy, their immune system responds to the allergen as if it were a foreign invader. The immune system causes the release of certain chemicals in the body, including one called histamine. When histamine is released under the skin, it causes the skin to swell and can lead to redness and itching. In some cases, this can be deadly.

Another common cause of skin inflammation is eczema, also known as atopic dermatitis. This chronic condition is marked by inflammation of the skin that is accompanied by itching. It is more common in children, but some people experience it later in life as well. Eczema is often seen in people who have allergies, such as hay fever, or who suffer from asthma. Although it can appear anywhere on the skin, the skin on a patient's arms and behind the knees is most affected.

Contact dermatitis, which develops when something that touches the skin causes it to become inflamed, is another common condition that can cause skin swelling. There are numerous substances that can cause this reaction. For example, a person may develop contact dermatitis due to soap, detergent, or perfume. Some people also develop it after their skin has come in contact with certain types of jewelry or poisonous weeds like poison oak. The red, itchy rash and swelling caused by contact dermatitis are not dangerous and cannot be spread to others.

An individual may also suffer from swelling of the skin as a result of a condition called cellulitis, which is caused by bacteria. It is marked by swollen, reddened areas of skin that feel warm and sore when touched. This skin infection can start with just one area and then quickly spread to other parts of the skin. Cellulite can affect any part of a person's body, but the skin on the legs is the most affected. If cellulite is not successfully treated in a timely manner, it can be life-threatening.
