Varicose veins: Causes, Symptoms, Prevention.

Varicose veins, also known as varicoses or varicosities, occur when your veins become enlarged, dilated, and overfilled with blood. Varicose veins typically appear swollen and raised, and have a bluish-purple or dark purple colour.

Symptoms of varicose vein

In the majority of cases, there is no pain, but signs and symptoms of varicose veins may include:

  • aching and uncomfortable legs
  • swollen feet and ankles
  • burning or throbbing sensation 
  • muscle cramps, particularly at night
  • itchy skin over the affected area 
  • skin discolouration
  • heaviness or fatigue in the legs

Causes of varicose veins

Weak or damaged valves can lead to varicose veins. Arteries carry blood from your heart to the rest of your tissues, and veins return blood from the rest of your body to your heart, so the blood can be recirculated. To return blood to your heart, the veins in your legs must work against gravity.
Muscle contractions in your lower legs act as pumps, and elastic vein walls help blood return to your heart. Tiny valves in your veins open as blood flows toward your heart then close to stop blood from flowing backward. If these valves are weak or damaged, blood can flow backward and pool in the vein, causing the veins to stretch or twist.

What are the risk factors

Experts are not sure why the walls of veins stretch or why the valves become faulty. In many cases, it occurs for no clear reason. However, some potential risk factors include:

  • Menopause
  • Pregnancy
  • Being aged over 50
  • Standing for long periods
  • Family history of vericose veins
  • Obesity

The following risk factors are linked to a higher risk of having varicose veins:

  • Gender: Varicose veins affect women more often than males. It may be that female hormones relax veins. If so, taking birth control pills or hormone therapy (HT) might contribute.
  • Genetics: Varicose veins often run in families.
  • Obesity: Being overweight or obese increases the risk of varicose veins.
  • Age: The risk increases with age, due to wear and tear on vein valves.
  • Some jobs: An individual who has to spend a long time standing at work may have a higher chance of varicose veins.

How do you prevent varicose veins

There's no way to completely prevent varicose veins. But improving your circulation and muscle tone may reduce your risk of developing varicose veins or getting additional ones. The same measures you can take to treat the discomfort from vericose veins at home can help prevent varicose veins, including:

  • Exercising
  • Watching your weight
  • Eating a high-fiber, low-salt diet
  • Avoiding high heels and tight hosiery
  • Elevating your legs
  • Changing your sitting or standing position regularly.

Treatment of varicose veins 

Treatment may not be medically necessary unless symptoms are causing problems. However, some people may want treatment for cosmetic reasons, because they are unhappy with the appearance of varicose veins.
If varicose veins are small and not too uncomfortable, elastic compression stockings may be recommended. These are worn during daily activities and help to compress the veins, keeping them from stretching and limiting any discomfort or pain.
For more problematic cases a range of procedures – surgical and non-surgical – are available to seal or remove varicose veins. A combination of treatment techniques may sometimes be used. Treatment options for vericose veins have changed significantly in the past 25 years and continue to evolve, especially the development of less invasive procedures that don’t require having to stay in hospital.
