The degeneration of valves can occur anywhere on the leg. Certain risk factors accelerate this process:

Weak connective tissue

Weak connective tissue is a major factor in the development of varicose veins. This is a hereditary predisposition to loose connective tissue, which gives way more quickly under strain. Women are increasingly affected by this, as their hormones have an additional effect on the connective tissue and reduce its firmness. In many young girls, the weakness of the connective tissue is exacerbated by the use of hormone-containing contraceptives.

Pregnancy

However, women are also increasingly affected by varicose veins for another reason, namely their pregnancies. Around 30% of all pregnant women suffer from vein problems with their first child and around 50% with their second child, although these often disappear again after the birth. The reason for this is the high pressure exerted by the uterus on the large blood vessels, which makes venous drainage from the leg more difficult.

Overweight & constipation

However, not only pregnancies, but also other factors that increase the pressure in the abdominal cavity can promote the formation of varicose veins. Obesity and chronic constipation can also prevent regular blood drainage.

Lack of physical activity

The amount of exercise plays an important role. A vein needs to be exercised daily, as this is the only way to keep its walls supple and elastic. If the amount of daily exercise decreases, the muscle fibers of the veins atrophy. This is the reason why standing or sedentary occupational groups such as hairdressers, cooks, secretaries, sales assistants etc. often complain of vein problems.

Age

Of course, age also favors the development of varicose veins, as the elasticity of the veins decreases in older people.

Toxins

Toxins such as alcohol can exacerbate leg problems by having an additional dilating effect on the vein walls.
