Psoriasis is a non-contagious skin disorder that most commonly appears as inflamed swollen skin lesions covered with silvery white scale. Among several types of Psoriasis, there is Plaque Psoriasis, which is characterized by raised, inflamed (red) lesions covered with a silvery white scale. The scale is actually a buildup of dead skin cells. There is also Guttate Psoriasis characterized by small red dots of psoriasis, which may have some scales.
Psoriasis may cause stiffness, pain, and joint damage. Scalp Psoriasis affects half the people who suffer from Psoriasis and is characterized by inflamed lesions covered by silver scaling in the scalp.
So what is the real deal behind psoriasis? Why is it so hard to treat?
Unfortunately psoriasis origins are not in your skin. Almost all researchers will agree that psoriasis is caused by your immune system.
Here is how it goes:
Your immune system in your skin is designed to protect you from cuts and bruises. If a bacteria happens to enter your skin, your immune system (the T cells) will send a signal to other T cells to start a ferocious attack on the foreign invaders. If the bacteria happens to cause some damage to your skin, the T cells will also send a chemical signal (called Cytokines) to your skin cells letting them know that some damage has happened and they need to regenerate and heal.

So how does psoriasis start?
In psoriatic patients, the immune system has become off balance. Something (a trigger) has caused the immune system of the patient to start sending false signals (Cytokines) to the skin. The skin then believes that it has been under attack and needs to rapidly regenerate in order to heal faster. A regular skin cycle, from the time that a new cell is born, grows, matures, reproduces and finally dies takes about 28 days.

A regular skin cycle, from the time that a new cell is born, grows, matures, reproduces and finally dies takes about 28 days.
In psoriatic skin, the cells are reproducing in such a hurry, that their complete cycle takes merely 5 days rising up to the surface faster than the neighboring unaffected skin. So this is where the plaques come from! This is the real reason behind the swelling, the scaling and the plaques. One of the messengers often used by T cells is TNF (a kind of Cytokine). Excess TNF is well known to cause inflammation, swelling and redness in the skin. These are other common symptoms in psoriatic skin and is again caused by the off-balanced T Cells. Even more unfortunate is the fact that T Cells usually call more T Cells (to help them control the false attack), causing the snow ball effect, spreading the psoriasis to other parts of your skin in your body.
What about the triggers?
Triggers are the onset of situations that lead to the immune system imbalance. Most often the main trigger is stress or a stressful event. It is strongly suggested that to prevent another psoriasis onset, you should try to avoid any triggers (such as excesive stress) that may have caused your psoriasis in the first place. No one really knows the reason why the immune system goes off balance all of a sudden, but one thing is for sure, the only way to treat psoriasis is at its origin, by regulating the immune system back to its normal function again, and the only way to prevent any recurrence may be avoiding these triggers.
So, is my diet has nothing to do with it?
Not really. As mentioned before, no one knows the real reason that lead to the immune system imbalance in the first place. No scientific correlation between specific diets and psoriasis has ever been found. So your diet may very well have little or nothing to do with your psoriasis itself. There are no "miracle diets" that can "heal your immune system". There is a catch though. We mentioned triggers before; and remember that most research will agree that triggers may be stress related. So anything that causes stress to your body may become a trigger. Sometimes people do not follow well balanced diets. Sometimes these diets lead to overweight and constipation. These two reasons alone may cause a lot of stress over your digestive system, and any stress on your digestive system may cause stress over your body as a whole.
