Why does my skin turn purple when touched?

Some people have particularly fragile skin, and they will find that their skin turns purple at the slightest touch. This situation may be that some part of the body has a lesion, which then manifests itself on the skin. Of course, some people cannot rule out the possibility that their skin’s stratum corneum is too thin. However, if your skin turns purple when touched, you must pay attention, as this may be a precursor to certain serious illnesses. Let's find out what is going on.

Your skin turns purple when you press it. Be careful of these diseases.

Sometimes I feel like I have no bumps or scratches and no pain or itching, but there are always bruises here and there, which are very obvious. Why do bruises and purples appear on the skin?

Why do people get bruises?

The bruises we see on the skin are actually blood from ruptured capillaries beneath the skin, which are the corpses of red blood cells that died heroically.

Depending on the size of the bruises, they will have different names - petechiae or hemorrhages (diameter <2 mm), purpura (diameter 3~5 mm) and ecchymosis (>5 mm). If the area is large, protrudes from the skin surface and has fluctuations, it is a hematoma.

There are always unexplained bruises, which may be due to these reasons

To understand the causes of bruises, let us first learn about the normal bleeding process of the human body.

When the human body is injured and bleeding, the blood vessels in the injured area contract first, reducing the local blood flow to reduce bleeding; then, the body's coagulation process is activated, and the blood clots formed by the aggregation of platelets and coagulation factors block the damaged blood vessels to achieve the purpose of stopping bleeding.

Blood vessels, platelets and coagulation factors are all involved in the hemostasis process, and problems with any of these factors may cause bleeding.

Thrombocytopenia

Hurry up and find the cause of the disease, it can be fatal in severe cases

Everyone knows that platelets are the main force responsible for blood coagulation. If they become less, the skin and internal organs will easily bleed. This type of bruising caused by thrombocytopenia is called thrombocytopenic purpura.

Thrombocytopenia is very harmful and can easily lead to repeated bleeding from the mouth and nose, heavy menstrual flow, dizziness and headaches. In severe cases, it can even cause life-threatening conditions such as bloody stools and massive gastrointestinal bleeding, so it must not be taken lightly.

Thrombocytopenic purpura can be caused by many reasons. The most common reason is autoimmune problems, which produce antibodies and cause thrombocytopenia (that is, the patient fights himself). In addition, other possible causes include thyroid disease, hypersplenism, etc.

The treatment of this type of purpura mainly relies on hormones, immunosuppressants and splenectomy, and it is prone to relapse after a severe cold or infection.

Capillaries are inherently fragile

Although there is no way, it won't be a big deal.

The reason why most people get bruises is related to family heredity. It is just because the capillaries under the skin are relatively fragile, and bruises will appear on the body with a slight impact, but it will not have any effect on your health.
