What is capillary bleeding? The reason is actually like this

Capillary bleeding is caused by many reasons. Although it does not look scary, you should never ignore it, because capillary bleeding may cause many diseases. If it is not discovered and treated in time, the consequences will be serious. Let’s first understand what capillary bleeding is!

Causes of capillary bleeding

Climatic and environmental factors, long-term living in a relatively harsh living environment such as thin air on the plateau and skin hypoxia, lead to an increase in the number of red blood cells and compensatory dilation of blood vessels. Over time, vasoconstriction dysfunction causes permanent capillary dilation. or sailors, cooks, farmers and athletes who are exposed to wind, cold and heat for a long time.

Stimulation by physical factors, such as temperature changes, causes the tolerance of capillaries to exceed the normal range, causing capillaries to dilate and rupture. Excessive sun exposure can cause chronic photodermatitis, dry skin, etc.

Abuse of cosmetics or long-term "monthly skin care" and improper skin peeling can cause sequelae. The acidic components of skin peeling products destroy the protective effect of the skin's stratum corneum and the elasticity of capillaries, causing capillaries to dilate or rupture.

Complications of certain local or systemic diseases.

Several common capillary bleeding diseases:

Henoch-Schonlein purpura is a common allergic hemorrhagic disease. Mainly affects capillaries. There was no thrombocytopenia and coagulopathy. In addition to skin purpura, the abdomen, joints and kidneys may also be affected.

Telangiectasia

In daily life, we often see some people with red facial skin, and we can see dilated capillaries with naked eyes, some of which are red or purple spots, dots, lines or star-shaped damages. This is telangiectasia, commonly known as hemoglobin.

The most common fundus hemorrhage is retinal capillary disease, which is mainly caused by damage to the capillary endothelium and increased permeability, resulting in blood seepage.

Differential diagnosis of capillary bleeding:

1. Venous bleeding: Dark red blood flows out of the wound rapidly and continuously. The method of stopping bleeding is roughly the same as that for capillary bleeding, but a little pressure should be applied with a bandage; if the bleeding is not from a large vein, the above method can generally achieve the purpose of stopping bleeding.

2. Arterial bleeding: It is violent and bright red in color, and gushes out in jets with the beating of the heart. Bleeding from the large arteries can cause death within minutes and the patient needs to be rushed to the hospital for emergency treatment.

External bleeding is usually treated by disinfecting the skin around the wound with iodine and alcohol, then covering the wound with sterile gauze and cotton pads and wrapping it with a bandage.
