There are red blood spots under the skin on the child's face

Generally, only adults are more likely to have red blood streaks, while children will not have them. However, this is not actually the case. Many parents now find that babies are also prone to red blood streaks, and they are all in the subcutaneous tissue on the face. Whether it is red or red blood streaks, it should be noted that the types depend on the red dots that appear and the approximate diameter of how many millimeters. Professional examination and diagnosis are required.

Main types

1. Bleeding points with a diameter less than 2 mm are called bleeding points;

2. Bleeding with a diameter of 2 to 5 mm is purpura;

3. Bleeding with a diameter greater than 5 mm is called ecchymosis; patchy bleeding with obvious protrusions is called hematoma.

main reason

Vascular factors

Bleeding of the skin and mucous membranes caused by congenital or acquired defects in the blood vessel walls. For example, hereditary hemorrhagic telangiectasia, due to increased local fragility of blood vessels, often causes repeated bleeding in the same area; Henoch-Schonlein purpura is a capillary allergic disease, due to the deposition of antigen-antibody complexes on the blood vessel walls, causing capillary dilation and increased permeability, leading to purpura or bleeding; the elderly are prone to senile purpura due to loose tissues and increased fragility of blood vessel walls.

Platelet factors

Platelets play an important and complex role in hemostasis. When the number or quality of platelets is abnormal, it often leads to bleeding of the skin and mucous membranes. In severe cases, there may be internal bleeding, such as bleeding in the digestive tract, urinary tract, respiratory tract, uterus, and even brain.

Coagulation and anticoagulation factors

Lack of coagulation factors or excess of anticoagulation factors in the blood can also cause large bruises on the skin, but deep hematomas or joint bleeding are generally more common.

Frequent subcutaneous bleeding often indicates a bleeding disease. Patients should go to the hospital in time to further find out the cause and receive treatment accordingly.

Subcutaneous bleeding can also occur during diving. Some divers inhale more oxygen due to high pressure when working in deep water. The oxygen liquefies in the blood and the oxygen content in the body increases. When a diver ascends, the pressure decreases due to his rapid ascending speed, and the oxygen inhaled vaporizes instantly, causing excessive pressure on the inner walls of the capillaries, bursting the blood vessels and causing internal bleeding. This was often the case with early diving accidents.
