Rashes

Rashes

Rashes (/ˈræʃɪz/; from Old French rasche, "to scratch") are changes in the skin's color, appearance, or texture. They may be localized in one part of the body, or affect all the skin. Rashes may cause the skin to itch, scale, swell or blister.

Types of Rashes

There are several types of rashes, including:

• Eczema: Also known as atopic dermatitis, it causes the skin to become red, itchy, and inflamed.
• Psoriasis: This is a chronic autoimmune condition that results in the overproduction of skin cells.
• Rosacea: This is a chronic skin condition that causes redness and visible blood vessels in your face.
• Hives: Also known as urticaria, these are raised, itchy bumps that appear suddenly.
• Heat rash: This rash appears as a result of sweat trapped in clogged pores and looks like small blisters or red lumps.

Causes

Rashes can be caused by a wide range of factors, including:

• Infections: This can be from bacteria, viruses, or fungi.
• Allergies: Certain foods, medications, or substances can lead to a rash.
• Autoimmune diseases: Conditions such as lupus or rheumatoid arthritis can cause rashes.
• Heat and sweat: These can lead to heat rash or sweat rash.

Treatment

Treatment for rashes depends on the cause. It may include:

• Topical creams: These are applied directly to the skin to reduce symptoms.
• Oral medications: These are taken by mouth.
• Light therapy: This involves exposing the skin to certain types of light.
