Itching, redness or peeling are common symptoms that can often appear on our skin, and we do not know what they are. However, they can mean one of several types of dermatitis in existence, requiring a lot of attention.
At first, the tendency is to ignore the problem or even learn to live with irritation. However, this practice is likely to be dangerous, as the inflammation can become chronic. So, the best thing to do is to see a dermatologist as soon as the first symptoms start.
But how and when do you need to seek medical help? In this post, we explain the causes and symptoms of seven types of dermatitis. Read on to find out the difference between them and how you can treat the problem!
What is dermatitis?
It is a skin irritation, characterized by redness, flaking, itching and the formation of small bubbles. These symptoms can arise in different ways, depending on the type of dermatitis and the area of the body affected.
It usually has an allergic origin, due to different factors, as we will talk about later. This is a problem that can appear in anyone, of all ages and for different reasons.
Either way, dermatitis can be cured. Just perform a treatment appropriate to your type and the symptoms that manifest themselves. For this, it is important to consult a dermatologist, who can prescribe medications and all necessary measures, including to prevent the problem from returning.
What are the types of dermatitis?
The types of dermatitis can be classified by their characteristics, causes and even the place where they appear. It is essential to identify them correctly, as the treatment varies from one to another. Next, see what they are, the causes and symptoms!
1. Atopic dermatitis
It is one of the most common types of dermatitis, being characterized by a chronic irritation of the skin, which becomes drier, with the formation of rashes and scabs that itch a lot. They tend to appear more frequently behind the knees and in the folds of the arms. It can also be accompanied by asthma attacks or rhinitis.
The causes for atopic dermatitis are quite diverse, such as genetic factors or response to allergic reactions due to environmental (dust, smoke, etc.) or immunological stimuli.
2. Contact dermatitis
It is an irritation of allergic origin, which generates rashes, redness, itching and flaking. In the acute phase, bubbles may appear. It is not contagious and, much less, it offers risk to the patient. However, it is quite uncomfortable and can spread quickly.
The most common places where contact dermatitis occurs are the hands and face, because they are more subject to exposure to irritating agents. They can be either cosmetics or jewelry, even some chemicals and cleaning products.
3. Seborrheic dermatitis
It is a chronic disease, which affects the person frequently, with flaking and formation of red and yellowish plaques. It happens more in regions of the body with many sebaceous glands, such as the scalp and face. It is more common in babies and young adults, especially men.
Seborrheic dermatitis is not contagious, but its causes are unknown. It is believed to be linked to genetic factors, which cause changes in the activity of the sebaceous glands and the immune system. However, some factors, such as the lack of proper hygiene and the presence of bacteria, could worsen the condition.
4. Stasis dermatitis
This is one of the rarest types of dermatitis. It results from the lack of circulation of blood and other fluids in the lower legs. Dermatitis stasis occurs more in people with varicose veins, and may develop chronic venous insufficiency.
5. Exfoliative dermatitis
Exfoliative is a more severe inflammation, which affects the entire surface of the skin, causing cracks, scales and redness. The upper cutaneous layer comes to loosen, that is, exfoliate – hence the name of the disease. It occurs as a side effect of some medications, such as barbiturates and antibiotics, or as a complication of another type of dermatitis.
6. Herpetiform dermatitis
The herpetiformis is manifested due to gluten intolerance (celiac disease), with the appearance of itching, small bubbles and an intense burning sensation. Therefore, there is no cure, being associated with eating foods that contain the substance.
7. Nummular dermatitis
Nummular dermatitis is an irritation in which crusts, scales, coin-shaped spots and some bubbles are formed. It also has unknown causes, affecting mainly elderly people . It is more frequent in winter, with the skin becoming dry with cold.
How are diagnosis and treatment made?
The diagnosis of all types of dermatitis is usually clinical, with the identification of causes and symptoms. Thus, it depends on a good conversation with the doctor, who will also assess the appearance of the inflammation. An allergic contact test can also be carried out to determine the substances that cause irritation in the patient.
Treatment can vary a lot, depending on the dermatitis. The first thing to do is to suspend the source of the problem, whenever possible. In the case of contact, it is necessary to suspend the use or avoid proximity to the causative agents.
In the case of atopic and seborrheic, because they are chronic, in addition to good hygiene, it is necessary to maintain control, treating irritation as soon as it arises. Those with celiac disease should not eat foods that contain gluten.
Along with these measures, the doctor may prescribe topical corticosteroid anti-inflammatory drugs and even immunomodulatory drugs , which help to increase immunity.
In addition, especially in the case of nummular dermatitis, it is essential to provide good hydration of the affected area, avoiding dry skin and flaking. The dermatologist can recommend special products for those who are allergic or more sensitive to any substance.
Anyway, the best way to treat any type of dermatitis is to make an early diagnosis. Only after the correct identification of the problem by a doctor will it be possible to adopt the necessary measures.
