Unfortunately modern science has not yet determined the actual causes of dermatitis it is currently thought that it is caused by the interaction between our genetic make up, immune system and the environment. It is recognised that the immune system of dermatitis sufferers is very fragile and sensitive and prone to adverse reactions from irritants and allergens. In many cases a family history of allergic conditions is also a major determinant for those who suffer from dermatitis..

A genetic predisposition may be aggravated by factors such as infections, food allergies, temperature, irritating chemicals, stress and humidity. In response to extreme temperature and humidity, dermatitis tends to flare-up. Sweating and psychological stress are other causes of dermatitis flare-ups.

Other forms of skin irritation seem to change the immunoglobulin E activity to increase. This seems to have the capacity to change the epidermal structure even as treatment is applied and after the exposure to the allegen is past, the condition reappears.

The Causes of Dermatitis Are Still Unknown

The pathogenesis of dermatitis is still unknown, however, several theories attempt to explain its cause which probably represent more than one condition. One of the current theories is that the underlying metabolical or biochemical conditions seem to indicate that induced skin disorder is genetically linked which elevates serum immunoglobulin E levels, The second theory for the causes of dermatitis is the defective T-cell function.

As we have seen the causes of dermatitis include a number of health conditions, genetic factors, allergies, and irritants, mental and physical stresses. We also need to point out that working in the wet is a main cause of dermatitis. Another form of dermatitis is Contact Dermatitis which is caused by direct contact with one of many irritants or allergens.

Different people react differently to different substances and allergic reactions are genetically determined. Skin burns and sunburn will increase the risk of dermatitis. It can be seen that the process and causes of contact dermatitis are much clearer, although little is known about what makes people susceptible to allergic dermatitis.

What Are The Main Types of Dermatitis

The three main types of dermatitis are atopic, contact allergy and contact irritant. They each have different triggers, although some are similar. Atopic dermatitis is a genetic disorder that is influenced by environmental factors when a highly reactive chemical substance comes into direct contact with the skin, However, little is known what characteristics make people susceptible to allergic dermatitis. Nummular dermatitis usually occurs when the weather is cold, this is common amongst people who have dry skin.

As modern science continues in its research, sufferers can avail of the various medications currently available both over the counter and through prescriptions . It is also a good idea to take a close look at what actually causes or irritates your dermatitis and stay clear of it thus reducing the likelihood of flare ups etc.
