There are four types of psoriasis mentioned below:
1) Postular psoriasis which can be life threatening and can lead to kidney failure, dehydration and severe infections;
2) Guttate psoriasis can occur after a bacterial throat infection;
3) Inverse psoriasis which can resolve without treatment and usually occurs in elderly patients;
4) Plaque psoriasis which can be seen as thickened scaly skin on either elbows, legs or back of the head, with soreness and itching.
Normal skin cells proliferate every 28-30 days. In psoriasis, there is an activation of the immune system reproducing skin every 3-4 days. This causes the epidermis to thicken and redden, as immature keratinocyte cells are pushed up to the outer layer.
Streptococcal bacteria may be negatively impacting on the immune system.
Psoriasis occurring in teenage years can be due to Streptococcal infection.
Psoriasis is viewed as an autoimmune disease, ie., when the body’s own systems are attacking itself .
Plaque psoriasis can be linked to stress, vaccinations.
In Traditional Chinese Medicine (TCM) treating psoriasis is by ‘cooling’ the blood, and so advisable to avoid ‘hot’ meat such as lamb/beef and spicy foods.
Blood tests and mineral tests are important as hypocalcaemia can be implicated in psoriasis.
