Dermatitis is a general term for skin inflammation. The skin will typically appear dry, swollen, and red. The condition can have many causes, but it’s not contagious.
Dermatitis can be uncomfortable for some. How itchy your skin may feel can range from mild to severe. Certain types of dermatitis can last a long time, while others may flare up, depending on the season, exposures, or stress. Some types are more common in children, and others are more common in adults. You may find relief from dermatitis with medications and topical creams.
Contact your doctor for an appointment if your skin is infected, painful, or uncomfortable, or if your dermatitis is widespread or isn’t getting better.
The symptoms of dermatitis range from mild to severe and will look different depending on what part of the body is affected. Not all people with dermatitis experience all symptoms.
In general, the symptoms of dermatitis may include:
Here are the most common types of dermatitis:
Other types of dermatitis include the following:
The causes of dermatitis vary depending on the type of dermatitis:
Certain things can trigger dermatitis and cause symptoms to flare, such as
Some types, such as dyshidrotic eczema, neurodermatitis, and nummular dermatitis may have unknown causes.
Factors that increase your chances of getting dermatitis include:
Some factors increase your risk for certain types of dermatitis more than others. For example, frequent washing and drying of hands will strip your skin’s protective oils and change its pH balance. This is why healthcare workers typically have hand dermatitis.
Your doctor will perform a physical exam and discuss your medical history before making a diagnosis. In some cases, a dermatologist can diagnose the type of dermatitis just by looking at the skin.
If there’s reason to suspect you might have an allergic reaction to something, your doctor might do a skin patch test. You can also ask for one yourself. In a skin patch test, your doctor will put small amounts of different substances on your skin. After a few days, they’ll check for reactions and determine what you may or may not be allergic to.
In some cases, your dermatologist may perform a skin biopsy to help determine the cause. A skin biopsy involves your doctor removing a small sample of the skin which is then looked at under a microscope. They can perform other tests on the sample to help determine the cause of your eczema.
Treatments for dermatitis depend on the type, severity of symptoms, and the cause. Your skin may clear up on its own after one to three weeks. If it doesn’t, your doctor or dermatologist may recommend:
Antibiotics or antifungal medications are usually given only if an infection has developed. Infections can occur when the skin is broken due to intense scratching.
Home care for dermatitis may include applying cool, wet cloths to the skin to reduce itching and discomfort. You can try adding baking soda to a cool bath to help reduce symptoms. If your skin is broken, you can cover the wound with a dressing or bandage to prevent irritation or infection.
Dermatitis can sometimes flare up when you’re stressed. You may want to look into alternative therapies like acupuncture, massage, and yoga to reduce stress.
Taking dietary supplements, such as vitamin D and probiotics, may help you manage the symptoms of eczema, according to the Mayo Clinic.
While dermatitis isn’t considered a serious medical condition, excessive scratching can lead to open sores and infections. These can spread, but they rarely become life-threatening.
You can prevent or control potential flare-ups with treatment. You may find the most relief in sticking to the treatments your doctor has prescribed.
Awareness is the first step in avoiding dermatitis. You’ll want to avoid contact with allergens or substances that cause rashes, such as poison ivy. But if you have eczema, which isn’t always preventable, your best option is to prevent a flare-up of symptoms. You’ll want to avoid scratching the affected area. Scratching can open or reopen wounds and spread the bacteria to another part of your body.
Another way to prevent excess dry skin is by taking shorter baths, using mild soaps, and using warm instead of hot water. Most people also find relief by moisturizing frequently. The Washington Department of Labor and Industries recommends using water-based moisturizers after washing hands and oil-based moisturizers for extremely dry skin.
