What are these little dots on the body?
01
A small red dot on the body
It may be a vascular nevus
If you're on it
There are also small red particles that are raised
Shape: 清晰,不pain不痒
Then don't worry too much
This thing is actually called a "vascular nevus"
Nothing is wrong
Essentially
It is the surface of the skin
Red dots produced by telangiectasia and hyperplasia
Inside the red dot is flowing blood
However, it is more common in the elderly population
But the statistics found
5%~41% of people in their twenties
Vascular nevi will appear
Most vascular nevi will go away on their own
Just leave it alone
There are also a small number of "nail households" who rely on it
It's up to you to care
If you really care
Go to the dermatology department of a regular hospital
Just find a doctor and use a laser "biu" to drop it

Some "little red dots"
It could be a disease
There are also some diseases
It can also appear as a "red dot"
It is easy to be confused with vascular nevi
It's important to remember:
01
Spider angiomas
This kind of middle point
Branches of blood vessels radiate to the periphery
A red dot that resembles a spider
叫蜘蛛痣
Press firmly on the center point
The surroundings will fade
Spider angiomatas are caused by dilation of the terminal arterioles of the skin
It tends to grow on the face, neck, arms and upper body
It is associated with increased estrogen levels
Estrogen has a dilating effect on blood vessels
As soon as the blood vessels dilate, the skin is stretched out with red spots
Spider angiomas can appear in normal people
For example, children and pregnant women
May also appear in:
in patients with liver disease
Spider angiomatas in children are usually present all the time
Individuals will subside on their own
Spider angiomatas during pregnancy in pregnant women
Most of them disappear about 3 months after giving birth
But if there are spider angiomas on the body
In the short term, there will be a large increase
I have to go to the hospital for a check-up
Assess whether there is a problem with the liver
According to the information
Boys have spider angiomas on their bodies
Eighty-five percent of liver tissue is diseased
30% of them are:
This is because
Estrogen metabolism takes place in the liver
The liver is pulling the crotch
Estrogen is not controlled
It is easy to have a lot of spider moles on the body
02
Henoch-Schonlein purpura
Henoch-Schonlein purpura (IgA-associated vasculitis)
It is an allergic inflammation
The autoimmune response is often abnormal
It causes inflammation of many small blood vessels throughout the body
In addition to the rash on the extremities
It can also cause:
Abdominal pain: mostly in the lower abdomen
Joint swelling and pain: mainly in the knees and ankles
Nephritis: such as hematuria, foamy urine
This disease poses a certain threat to health
Normative treatment is required
Once the problem is suspected
