After 48 hours, the hematomas generally become red-black. At the end of the first week, they turn purple and then change to green and finally to yellow, until disappearing after several weeks. The causes of the appearance of a bruise or hematoma are usually not the same. Do not hesitate to consult especially when they are spontaneous, when it continues to swell or when they are on the skull.
What are the most common causes of bruising?
With age, the skin changes. The superficial layer is less elastic and has less collagen. The skin will therefore recover less quickly. There will also be less superficial fat, the skin will shrink and be thinner. Conclusion, the subcutaneous vessels will be less resistant to shocks.
Vitamin C participates in the formation of collagen. Several American studies put the frequent appearance of bruises plus the lack of vitamin in correlation. Vitamin C is present in large quantities in fruits and vegetables. Some people find it difficult to buy fresh fruits and vegetables. In this case, it is better to buy a vegetable and freeze it to keep the vitamins to a minimum. Also, if you bruise, do not hesitate to take a little zinc.
Some people need to take blood thinners to treat certain illnesses. These drugs are essential and life-saving. Others must take aspirin chronically for cardiovascular prevention. These drugs can cause weakening of the vessels and therefore the appearance of bruising.
We are talking about venous return to refer to the stage of blood circulation where oxygen-depleted blood. PFor example, with age, venous return will be less effective. The venules on the surface will have to support the column of blood, will expand and be much more sensitive to the slightest shock. It’s the same phenomenon that happens when you expose yourself to the sun for too long.
