What is the reason for protruding blood vessels in hands and feet

Generally, if we come into contact with cold water immediately after strenuous exercise, the blood vessels in our hands and feet will become very thick, which is the phenomenon of protruding blood vessels in our hands and feet. Of course, there are many other reasons that can cause protruding blood vessels in the hands and feet, but we don’t know much about them. So, what are the reasons for protruding blood vessels in the hands and feet? Let us give you some basic knowledge below!

1. Drug addicts: People who use syringes to take drugs are prone to damage to the valves of the deep veins, which is a common cause of varicose veins.

2. The key cause of varicose veins is perforator failure: The perforator veins connecting the superficial veins and the deep veins also have valves to prevent blood from flowing from the deep veins to the superficial veins. However, when the perforator vein valve function fails, blood flows freely, which puts pressure on the superficial veins and causes the veins to dilate.

3. Congenital causes: The patient may have some minor problems with his valves, which, combined with acquired pressure, lead to varicose veins. This is the most critical cause of varicose veins.

4. Pregnant women: Female hormones will cause the veins to dilate, and the valves cannot cover the veins and prevent blood from flowing back.

5. Varicose veins can cause bleeding: The skin at the site of varicose veins is very fragile due to insufficient nutrition, and a slight trauma can easily cause the skin of the varicose veins to rupture and cause heavy bleeding. Because the cross sensory nerves at the lesion site are damaged, no pain is felt when bleeding occurs. If it is not discovered in time when sleeping at night, serious consequences may occur.

6. Varicose veins can cause edema in the lower limbs: due to blood blockage, blood reflux occurs in the veins, and the patient will experience edema during the day, which will be reduced after resting at night.

7. Varicose veins can cause ulcers: The most common consequence of varicose veins is that varicose veins cause ulcers to form after the skin is traumatized due to insufficient nutrition supply. This type of ulcer can be long-lasting and cause local foul smell and pus, which can have a serious impact on daily life.

8. Varicose veins can cause thrombosis: Some patients may develop thrombosis in the varicose superficial veins, which manifests as local redness, swelling and pain, lump formation, and pain that affects walking. If not treated promptly, the thrombus may spread upward or through the communicating veins to the deep veins, causing deep vein thrombosis and the risk of life-threatening pulmonary embolism.

If the blood vessels in the hands and feet are always in a state of expansion, then there is a high possibility that some disease has occurred. At this time, the patient needs to go to the hospital for examination in time to see if there are other reasons, because different symptoms may also cause different diseases. Early treatment can effectively prevent the aggravation of the disease.
