Disease 10. Contact Dermatitis: When Skin Meets Irritant
Contact dermatitis is a type of skin inflammation that occurs when the skin comes into contact with an irritating substance or allergen. There are two main types: irritant contact dermatitis and allergic contact dermatitis. Irritant contact dermatitis is more common and results from direct skin contact with substances such as detergents, solvents, or harsh chemicals. Allergic contact dermatitis occurs when the skin comes into contact with a substance that triggers an immune response, such as poison ivy, nickel, or certain fragrances.
Symptoms of contact dermatitis include redness, itching, swelling, and blistering. The best treatment for contact dermatitis is to identify and avoid the offending substance. Over-the-counter creams containing hydrocortisone can help alleviate itching and inflammation, while oral antihistamines may provide relief for more severe symptoms.
If symptoms persist or worsen, it’s essential to consult a healthcare provider, as a prescription-strength topical corticosteroid or oral medication may be necessary. Patch testing can also be helpful in identifying the specific allergen causing allergic contact dermatitis. (10)
