Know that there are many factors that can contribute to trigger psoriasis or even contribute to its aggravation?

Psoriasis is a chronic disease* characterized by a development of skin cells faster than normal, eventually crowding at its surface, forming lesions covered by dead cells of white or silver.

*The psoriasis was approved as a chronic disease by the Portuguese Parliament in January 2010.

The incidence of psoriasis is low (according to some studies affects 1% of the population), which is why there is still a great ignorance of this pathology, even on the part of those who suffer.

Although not being contagious, is a disease that is uncomfortable and sometimes very painful, encompassing in its symptomatological sensations of itching and burning.

Its causes are still unknown, suspecting that it is an immune reaction of the body against his own skin. Perhaps a proof of this is the deterioration in situations of emotional stress.

Although the main cause of the disease is still not fully known, it is appropriate to identify some factors that may trigger and/or worsen:

Excessive alcohol consumption

Since that began research on this theme, we found that the excessive consumption of alcohol can have a direct influence on the onset and/or exacerbation of psoriasis.

In fact, alcohol does not act only as a trigger, but can also delay the treatment of the disease. People who suffer from psoriasis should limit the intake of alcohol.


Many believe that genes are the main cause of psoriasis. However, it is thought that the disease is triggered by some other factor parallel to the genetics. Indeed, it should be taken into account that there are people without a family history of the disease and that, in any moment of your life, to develop.


Stress is one of the main causes of hundreds of diseases. In fact, stress can not only be the origin of the disease, as well, many times, to worsen. Daily is not easy to deal with the stress. However, there are many techniques that can help minimize this question. Must always bear in mind that your health is in the first place.


It is known that tobacco consumption worsens the symptoms of psoriasis. On the other hand, tobacco consumption increases the likelihood of a person to develop the disease. It is not easy to stop smoking, but keep in mind that it is an excellent decision, especially for those who suffer from psoriasis.


So far there is no correlation between food and psoriasis. However, if you have developed psoriasis, should avoid certain foods:

  • Gluten
  • Fatty foods
  • Refined Sugar
  • Citrus fruits
  • Processed Food

You can always try an elimination diet to see which foods that can trigger and/or worsen your psoriasis.

Skin lesions

Any trauma to the skin may be a trigger for an outbreak of psoriasis. The most common trauma on the skin are: tattoos, scrapes, insect bites, cuts, sunburn, etc..

Steroids and Other Medicines

There are some medicines that can interfere with the immune system of your body and lead to psoriasis. Some of the medications that can cause psoriasis: steroids, beta-blockers, non-steroid, indomethacin lithium and even pills for treatment of malaria.


Some types of infections, such as the streptococcal pharyngitis - infection of the throat - or Candida Albicans - thrush or infection by fungi - can also lead to the spread of psoriasis. These infections should be treated as soon as possible.

Hormonal Changes

Hormones play a very important role in maintaining the natural balance of the body.

The hormonal imbalances, especially during the phase of puberty or menopause, may trigger a condition of psoriasis.

Weather Conditions

When subjected to extreme weather conditions, many people see your psoriasis stiffer. The rigorous cold can cause skin dryness, itching and redness. In the same way, the sunburn can also lead to skin damage and, consequently, to psoriasis.

The best will be to avoid outdoor activities with adverse weather conditions.

Final Notes:

As other diseases of the skin, depending on the symptoms, psoriasis may be considered moderate or severe.

In any case, the treatment of psoriasis always need for medical intervention.

However, we can also say that prevention is the best cure, by which prevent the triggering factors will always be a good option.
