Psoriasis is a chronic disease with rapid flare-ups and remissions. The disease occurs due to many causes, of which 2 main causes are due to the immune system and genetic factors. The main treatment goal of the disease is to stop skin cells from growing too quickly.
1. Causes of Psoriasis
The cause of psoriasis is still unknown. However, over decades of research, scientists have come to the same conclusion about two main factors: genetics and the immune system.
Trắc nghiệm: Bận rộn có ảnh hưởng đến sức khỏe của bạn không?
Cuộc sống hiện đại khiến chúng ta vì quá bận rộn mà quên chăm sóc sức khỏe cho chính mình. Ai cũng biết rằng lịch trình làm việc cả ngày có thể khiến bạn kiệt sức, nhưng cụ thể bận rộn ảnh hưởng thế nào tới sức khỏe? Hãy cùng làm thử bài trắc nghiệm dưới đây.
1.1 Immune system Psoriasis is an autoimmune disease. In a normal body, white blood cells are deployed to attack and destroy invading bacteria and fight infections. In psoriasis, T-lymphocytes mistakenly attack skin cells.
This false attack triggers new skin cells to form too quickly. Normally, skin cells are replaced every 10 - 30 days. With psoriasis, new cells grow every 3 - 4 days. The accumulation of old cells is replaced by new cells that produce silvery scales.
The attack by T lymphocytes on skin cells also causes areas of the skin to become inflamed and red.
1.2 Genetics Psoriasis is hereditary, but only a small percentage. The disease tends to be inherited by skipping a generation. For example, if a grandfather is sick, his grandson is at high risk of getting sick. In general, you have a higher risk of developing psoriasis if a family member has it.
2. Risk factors for disease

The most common triggers for psoriasis include:
2.1 Hormonal changes Diseases often appear or flare up during puberty or menopause. During pregnancy, the symptoms of the disease gradually decrease or even disappear. But after childbirth, the disease can flare up again.
2.2 Alcohol Heavy drinkers are at higher risk, especially younger men. Alcohol can make treatments less effective.
2.3 Smoking Smoking can double your risk of psoriasis. If you have another family member with the disease, your risk is 9 times higher. Smoking makes it harder to get rid of disease symptoms. It can be more severe with pustular psoriasis, which affects the palms of your hands and soles of your feet.
2.4 Stress Scientists think that the immune system can be messed up by emotional and mental stress in the same way it responds to physical problems like trauma and infection.
2.5 Medications Some medications can make the condition worse, including:
Lithium: Treats bipolar disorder and other mental illnesses Other high blood pressure and heart medications: Propranolol ( Inderal) and other beta-blockers, ACE inhibitors, and quinidine Antimalarials: Chloroquine, hydroxychloroquine (Plaquenil), and quinacrine Anti-inflammatory drugs: Indomethacin (Indocin) 2.6 HIV Psoriasis is often worse in the early stages of HIV disease. After applying HIV treatment, the symptoms of eczema also gradually decreased.
2.7 Other infections Strep infections, in particular, increase the risk of guttate psoriasis. Children will often get strep throat before their first flare-up. In addition, the disease can also flare up after other health problems such as earaches, bronchitis, tonsillitis, or respiratory infections such as colds, flu, or skin problems.
2.8 Sunlight Exposure to natural sunlight is fine for most people with psoriasis. However, in rare cases, sunlight can make the condition worse. Therefore, you should protect your skin if you go out.
2.9 Skin Injury An excessive cut, scraping, biting, infection or scratching can also cause psoriasis
2.10 Weight Obese people tend to have psoriasis and wrinkles.
2.11 Weather Psoriasis can be more severe in winter. Dry air, less natural sunlight, and cold temperatures can make symptoms worse. Therefore, you should remember to keep your skin moist in winter.
