Veins are present in almost every part of the human body, and they must function properly for us to be fit and healthy.
There are valves in veins to make sure that the blood goes in one direction only. These valves are present at a distance of one inch each, making sure the blood doesn’t change its direction.
The circulatory system is made up of veins, arteries, capillaries and of course the heart. Veins are responsible for transporting deoxygenated blood back to the heart while arteries circulate oxygenated blood from the heart to different parts of the body.
It is important for the veins to work properly as their failure can lead to vein diseases. You must learn what causes vein disease and how to treat such conditions if you wish to lead a healthy and happy life.
Before we learn the causes of vein diseases, let’s get to know the types of veins in our body first:
Types Of Veins In The Body
There are 3 types of veins in our body.
Superficial Veins: They lie close to the skin.
Deep Veins: They are beneath the muscles.
Perforating Veins: They connect deep veins and superficial veins together.
Now that we know the functionality of veins, let’s get know how these veins can malfunction and cause vein diseases
It should also be mentioned that there are several kind of vein diseases, but the causes are usually same. Now let’s have a look at the causes of vein diseases:
Causes Of Vein Diseases
There are one-way valves in veins that make sure that blood flows in one direction only. However, these valves may fail and cause blood to pool in the veins inside the legs, causing many health problems.
When the valves in the veins stop working, following diseases can occur:
- Blood clots
- Spider veins
- Varicose veins
- Leg pain
These are some of the most common vein diseases but there are many more.
- Another common cause of vein disease is age. People who are 50 or above are more likely to suffer from vein diseases like varicose veins and spider vein. An aged person has low elasticity in the veins due to which the valves are affected and weakened. Such people need to be very careful about their lifestyle and must be active so that blood flows smoothly and without any trouble.
- Other than that, vein diseases can also be caused when a person sits or stands for too long in the same posture. This blocks the veins and causes the blood to pool. Basically, we need to be active so that the blood flows in the required manner and being in one position for too long can cause problems.
- Vascular malformations and pelvic tumors are another reason to cause vein disease called CVI. This happens because of the formations of blood clots in the veins that block the flow of blood. This results in swollen legs and also causes mobility issues for some people.
- Pregnant women are also prone to vein diseases because during this phase, the volume of blood in their bodies increases while the blood flow decreases from legs to the pelvis. This change in the female body happens to support the growing fetus but can also cause the veins to enlarge and cause vein diseases like varicose veins or spider veins.
- Obesity is another reason to get vein diseases. Overweight people have to bear an added pressure on the veins when they perform any physical activity. Hence, the valves in the veins get damaged and it disrupts the blood flow, causing the legs to swell and cause pain. So make sure to maintain a healthy weight.
- This disease is also hereditary and people with a family history of vein diseases are at a higher risk.
Vein diseases are of many types but the cause is almost the same for all, damaged valves in the veins that causes the blood to flow backward.
