Do you notice blue or purple swollen and protruding veins in your legs? Do you feel heaviness or pain in your legs after prolonged standing? These symptoms may be a sign of varicose veins, a very common condition that affects about 30% of adults at some point in their lives. In this comprehensive guide, we provide you with everything you need to know about varicose veins, from symptoms and causes to the latest treatment and prevention methods, based on information from Mayo Clinic, NHS, WebMD, and the Saudi Ministry of Health.
What are varicose veins?
Varicose veins are enlarged, swollen, and twisted superficial veins under the skin, often appearing dark blue or purple. They occur when the valves in the leg veins weaken and lose their ability to efficiently pump blood back to the heart, causing blood to pool in the veins and making them swell. Varicose veins often appear in the legs and feet because standing and walking increase pressure on the veins in the lower part of the body.
It is important to distinguish between varicose veins and spider veins — the latter are smaller and less dangerous, appearing as a network of fine red or blue lines under the skin without swelling or protrusion.
Causes and risk factors
The main cause of varicose veins is the weakening or damage to vein valves. In healthy veins, valves work in one direction to prevent blood from flowing backward. When these valves weaken, blood pools in the veins instead of flowing to the heart, causing them to dilate and swell.
Factors that increase the risk of varicose veins:
- Age: Risk increases with age as veins lose their elasticity and valves weaken
- Gender: Women are more prone to varicose veins due to hormonal changes during pregnancy, menstruation, and menopause
- Pregnancy: Pressure on the pelvic and leg veins increases with the increase in blood volume in the body
- Heredity: If one of the parents has varicose veins, your likelihood of developing them is higher
- Excess weight: Obesity puts additional pressure on the veins
- Prolonged standing: Occupations that require standing for long hours (such as teaching and nursing) increase pressure on the veins
- Lack of movement: Prolonged sitting without movement weakens blood circulation in the legs
Symptoms — when should you worry?
Varicose veins do not always cause symptoms in all sufferers, but common symptoms include:
- Appearance of blue or purple swollen and twisted veins under the skin
- Pain, heaviness, or discomfort in the legs, especially after prolonged standing
- Swelling in the ankles and feet that worsens in the evening
- Itching, dryness, or discoloration of the skin around the affected vein
- Muscle cramps in the legs, especially at night
- Sensation of burning or throbbing in the legs
According to the NHS, if a leg ulcer appears and does not heal after two weeks, or if varicose veins bleed, you should seek immediate medical help.
Latest available treatment methods
1. Sclerotherapy
Chemical solution is injected into the affected vein, causing scarring and closure of the vein. Blood reroutes through healthier veins nearby, and the treated vein gradually fades. This procedure is non-surgical and does not require general anesthesia, making it the ideal choice for small to medium varicose veins.
2. Endothermal Ablation
Radiofrequency (Radiofrequency Ablation) or laser energy (Endovenous Laser) is delivered through a catheter inserted into the vein via a very small incision. Heat seals the treated vein. This minimally invasive procedure is performed under local anesthesia and is currently the first-line treatment for large varicose veins in the legs.
3. Vein Stripping
In severe cases, a doctor may perform surgery to tie off and remove the affected vein through small incisions. This surgery has become less common due to modern, less invasive treatments.
4. Compression Stockings
Compression stockings are the first and simplest line of treatment. They apply pressure to the legs to improve blood flow, reduce pain, and alleviate swelling. They are prescribed because they come in different pressure levels to suit each condition.
5 Practical Tips for Managing Varicose Veins
- Elevate your legs: Sit or lie down and elevate your legs above heart level for 15-20 minutes several times a day — this helps blood flow back to the heart and reduces pressure on the veins.
- Walk daily: Regular walking (at least 30 minutes a day) activates blood circulation in the legs and strengthens calf muscles that help pump blood.
- Maintain a healthy weight: Losing excess weight significantly reduces pressure on leg veins.
- Avoid prolonged standing or sitting: If your job requires standing or sitting for hours, take a break every 30-60 minutes to move your legs or walk for a few minutes.
- Wear compression stockings: Consult your doctor about the appropriate pressure level for your condition, and wear them especially during long periods of standing or air travel.
Myth vs. Fact
Myth: Sitting in a squatting position causes varicose veins.
Fact: There is no scientific evidence linking sitting in a squatting position to varicose veins. The real causes are weak venous valves, genetic factors, and hormonal influences.
Myth: Varicose veins are just a cosmetic issue.
Fact: Varicose veins are not just a cosmetic problem. In advanced cases, they can lead to complications such as skin ulcers, phlebitis (vein inflammation), superficial blood clots, and bleeding upon injury.
Myth: Exercise worsens varicose veins.
Fact: The opposite is true — regular exercise such as walking, swimming, and cycling improves blood circulation, strengthens muscles, and helps relieve symptoms. However, heavy weightlifting is not recommended as it may increase pressure on the veins.
Frequently Asked Questions (FAQ)
Q: Can varicose veins disappear without treatment?
A: Varicose veins rarely disappear on their own. In most cases, they worsen over time without treatment. However, symptoms can be relieved and managed through lifestyle changes and the use of compression stockings.
Q: Are varicose veins dangerous to health?
A: In most cases, varicose veins are not dangerous or life-threatening. However, they can cause complications such as skin ulcers, superficial vein inflammation, and bleeding. In rare cases, they may be associated with deep vein thrombosis (DVT). Consult your doctor if you are concerned.
Q: Is treatment available in the Kingdom of Saudi Arabia?
A: Yes, all modern treatments for varicose veins are available in Saudi Arabia, including sclerotherapy and thermal laser ablation. You can consult vascular doctors in public and private hospitals. The Saudi Ministry of Health provides information about varicose vein treatment centers through the “Seha” platform.
