First, long-term exposure
If a person is exposed to the sun for a long time, he may suddenly grow moles. This is because the ultraviolet rays in the sun's rays can make the human body produce a lot of melanin. If melanin accumulates to a certain amount, it may suddenly grow moles. Therefore, if you are a person who often works in the sun for a long time, it is not a big problem to suddenly grow a mole. Of course, ultraviolet rays do great harm to the skin, so try not to expose yourself to the sun.
Second, endocrine disorders.
For example, if a woman is pregnant or in a physiological period, endocrine disorders may occur. In this way, the metabolism of melanin in the body will be abnormal, and moles may suddenly grow. Therefore, if you feel that your endocrine system is out of balance, or you are in a special period, then you don't have to worry too much about moles.
Third, liver disease.
Severe liver disease can lead to telangiectasia of skin. Under such conditions, the body will suddenly grow a red mole and grow a lot, not one or two. If this happens, we should be alert to whether there is something wrong with the liver.
Therefore, through the above analysis, we can know that the sudden growth of moles is not necessarily a liver problem, so we don't have to panic too much.
