Hello, you can check the liver function, which is related to capillaries. If the liver function is normal, it generally has little effect on the body!

There are red spots on the skin, which are often obvious. These red dots are different in nature, so we should pay attention to distinguish them.

The most common red spot is nevus, as small as a needle tip and as big as sesame, slightly higher than the skin surface. In fact, red moles, like moles, have no effect on health. Except for obvious changes in the near future, treatment is generally not needed.

There is a spider nevus, the center of which is slightly higher than the skin surface, and there are many capillaries extending outward around it. It is mainly seen in patients with liver cirrhosis and should be treated according to the cause.

Another kind of red spot on the skin is the manifestation of subcutaneous bleeding. They are bright red at first, then gradually turn purple after two or three days, then yellow-brown, and finally disappear without leaving a trace.

Subcutaneous hemorrhage as thin as a needle tip is called petechiae. The older one is called purpura. More than 0.5 cm in diameter is called ecchymosis, which is also commonly known as Qing Wu block. Congestion is sometimes found in some acute infectious diseases, such as epidemic cerebrospinal meningitis and some serious bacterial infections, such as sepsis and subacute bacterial endocarditis. In addition, the etiology of subcutaneous hemorrhage can be attributed to vascular factors and platelet factors.

Subcutaneous hemorrhage caused by vascular factors, in addition to vascular injury, is mainly caused by allergies, medically known as allergic purpura. Some people are allergic to protein in fish, shrimp, milk, eggs and other foods; Bacterial, viral and parasitic infections can also cause allergies; Some drugs, pollen and even cold stimulation can also cause subcutaneous capillary dilation, increase the permeability of blood vessel wall, and some blood components ooze out to cause subcutaneous bleeding. Henoch-Schonlein purpura is mainly found in limbs and buttocks, and it is often symmetrically distributed on the left and right sides of the body, and appears repeatedly in batches. The parts where purpura appears may have itching sensation. Henoch-Schonlein purpura can also cause intra-articular bleeding and gastrointestinal bleeding. Occasionally accompanied by nephritis. Patients with henoch-schonlein purpura should find out what substances they are allergic to and get rid of contact with these substances. Drugs such as phenanthrene, vitamin C and calcium gluconate have therapeutic effects on this kind of purpura. Severe cases can be treated with adrenocortical hormone.

Because of the relaxation of subcutaneous tissue and the increase of capillary permeability, purpura can also occur in the elderly, which is called senile purpura. Some young women are prone to ecchymosis, which is called simple purpura. At present, the cause is not very clear, and this situation can be treated with vitamin C.

Purpura caused by platelet factor naturally manifests as thrombocytopenia. Thrombocytopenia can be seen in aplastic anemia, leukemia, hypersplenism, uremia and other diseases, and its treatment should of course focus on these diseases.

Idiopathic thrombocytopenic purpura (ITP) is currently considered as an autoimmune disease, because these patients often have anti-platelet antibodies, which will destroy their own platelets and lead to bleeding. This disease is very common among young women, and it tends to recur. Mild manifestations are subcutaneous bleeding, and severe cases may have visceral bleeding. Idiopathic thrombocytopenic purpura can also be treated with antiallergic drugs. Other Chinese and western medicines such as coenzyme A and buffalo horn powder also have certain curative effects. Severe cases can be treated with adrenocortical hormone. Massive bleeding may require platelet transfusion.

The bleeding caused by thrombocytopenia should be carefully diagnosed. Because platelet counts are often inaccurate. Therefore, it is necessary to repeatedly check and do bone marrow examination if necessary.
