Varicose veins are enlarged veins near the surface of the skin in the legs and ankles. Associate Professor Tan Seck Guan from the Singapore General Hospital clears some misconceptions on the causes.
Symptoms and risk factors for varicose veins
Varicose veins typically affect the legs and thighs. These enlarged veins may cause mild swelling of the ankles, especially after long hours of standing or walking. Other symptoms can include the following:
- throbbing in the legs,
- aches and pain,
- darkening of the skin,
- rashes and
- ulcers on the ankles.
Not all patients with varicose veins suffer from these symptoms. Some have no medical complaints even after decades of having them.
Contributing factors for varicose veins
If your family members have varicose veins, you are more likely to develop them. Standing for long periods can worsen the condition.
Varicose veins usually become more obvious during middle age.
Women prone to the condition may develop varicose veins during pregnancy because of hormonal changes and increased pressure in the veins as the uterus grows.
Weight gain during pregnancy also puts more pressure on leg veins. After delivery, varicose veins may improve or subside, but in some women, the symptoms may persist.
Varicose veins are more common in women due to hormonal changes, especially during puberty, pregnancy and menopause. Birth control pills are also believed to increase a woman’s risk of developing varicose veins.

If the walls of your veins are weak, you are more likely to develop varicose veins whatever your lifestyle habits.
Weight gain causes varicose veins.
Obesity is associated with the presence of varicose veins and worsening venous disease, but losing weight does not necessarily “cure” varicose veins.
Certain exercises and stockings can prevent varicose veins.
There is no non-surgical method to prevent varicose veins or shrink them once they have formed, although a recent study suggests that wearing regular stockings may help slow the progression of venous disease.
