The whole body veins are obvious, if the whole body veins are obvious, it means the patient’s skin is thin, and the body is thin, the subcutaneous fat is very little, the subcutaneous veins are very close to the skin, so you can see the veins under the skin through the skin, and you can see the veins under the skin very obvious to the naked eye. In addition, there is another situation where the veins are closer to the skin because of the dilated veins, so you can also see the bruises under the skin, and this time you need some tests, such as ultrasound or phlebography, to find out the specific reason for the obvious bruises. If the cause is thinness, in this case, you can increase your diet and metabolism to increase the subcutaneous fat, and the visible bruises will improve. If it is a vascular malformation, this is the time to target the treatment for the specific condition.
