What are varicose veins?

Varicose Veins Meaning

Veins are tubular channels which carry blood back from the body to the heart. When these veins become swollen (greater than 3 mm) and twisted, they are called varicose veins. Although they can occur anywhere in the body, they are more common in the legs. 

The word "varicose" comes from the Latin, resembling the word "twisted". These veins may occur in clusters that look like spider webs. A single large vein can also be readily visible, especially when standing. 

Up to 20% of the adult population has some form of varicose veins. They appear between the ages of 30 and 70 and usually get worse with age. Unlike in western countries, varicose veins are more common in males in India. 

Types of Visible Veins

There are various kinds of visible veins apart from varicose veins.

• Telengiectasias: These are also called spider or thread veins which are smaller (less than 1 mm) and closer to the skin. These are red or blue in colour and are commonly seen in legs or face. 
• Corona phlebectatica: These are also smaller veins distributed in a fan shaped pattern. These are commonly seen around foot and ankle.
• Reticular veins: These are larger than the previously described veins (1-3 mm) and closer to the skin. These are usually blue in colour. Reticular veins spread in a mesh pattern and cover a larger skin area. 

Difference between Varicose Veins and other Visible Veins

The other visible veins are primarily a cosmetic problem. Most are painless and generally do not cause other health problems. In contrast, varicose veins are not always just a cosmetic problem. It may affect your life and can lead to serious health problems.

Causes of Varicose Veins

Varicose veins develop due to increased pressure in the veins that damages the venous wall or valves (cup shaped membranes which prevent blood from sliding back). These faulty valves make veins more prone to pooling of blood, a condition where pumping of blood back to the heart is ineffective and collects in the legs, ankles, and feet. Some of the risk factors that contribute to increased venous pressure or valve damage are as follows:

Medical history of blood clotting: Clotting of blood can damage vein walls or valves leading to the development of varicose veins.

Prolonged standing or cross-legged sitting: Sitting cross-legged or standing for long periods continuously can increase venous pressure, thus causing varicose veins.

Obesity: Being overweight or a person with a BMI (body mass index) of more than 26 can put more pressure on your veins and can cause varicose veins.

Pregnancy: Changes during the pregnancy can increase the risk of varicose veins. The weight of the growing baby puts pressure on the large blood vessels in the pelvis, altering blood flow and the raised blood volume can also enlarge the veins making pumping of blood back to the heart inefficient.

Prolonged exposure to sunlight: Excessive sun exposure can break down the collagen in your skin and weaken your blood vessels, resulting in varicose veins.

Ageing: Most people who develop varicose veins are between 40 and 80.

Medicines: Taking prolonged hormonal replacement therapy or oral contraceptive usage may also increase the risk of varicose veins.



Family history: If there is a family history of varicose veins, then the possibility of developing varicose veins will be very high.

Symptoms of varicose Veins

Usually, people don't show symptoms from varicose veins, except that they are conspicuous and embarrassing to look at. Varicose veins can worsen over the years, but this often progresses very slowly.

In addition to cosmetic embarrassment, the most common symptoms of varicose veins are:



• Pain in the affected area, especially after sitting or standing for long periods
• Dry, cracking, itchy skin around affected veins
• Throbbing or cramping in legs during rest
• Discolouration of the skin around the ankle
• Heaviness in legs, muscle fatigue
• Bulging of affected veins
• Leg swelling
• Varicose Eczema: Eczema may be familiar, but varicose Eczema would not be a popular term around us. It is a kind of Eczema that causes the skin on your legs to become itchy, red, and scaly and is at risk of peeling off, especially after contact.
• Lipodermatosclerosis: It is the medical name for skin scarring caused by varicose veins. It develops gradually over the years and can lead to venous ulcers if left untreated.

Complications of Varicose Veins

Many people who suffer from varicose veins never experience any problems and do not need treatment. They can manage their symptoms daily without needing treatment. However, if complications do occur, they should be treated as soon as possible. It may take years for these complications to develop.

Complications that can occur with the progression of varicose veins symptoms are as follows:

Bleeding: In the case of varicose veins in the legs, these delicate veins can bleed easily if facing circumstances like hitting the leg against a surface, bruising, or being cut from participating in sports. If untreated in these patients, bleeding can be challenging to stop.

Thrombophlebitis: Thrombophlebitis is medical terminology for venous inflammation due to blockages or blood clots. This inflammation causes swelling and pain in the affected area. The affected leg will have a reddish appearance and feels warm to the touch.

Pulmonary Thromboembolism: When the blood clot in the varicose vein breaks and migrates in to the lung veins it is called pulmonary thromboembolism. This can lead to breathlessness and decreased oxygen in the blood. If severe, this can be life-threatening.

Venous Ulcer: These are ulcers that occur on the lower part of the leg. It happens because of the increased pressure and swelling of damaged veins that release fluid into the skin. This fluid collects under the skin, making it thick, rough, and inflamed. This skin breaks down and forms ulcers. These ulcers usually occur around the ankle.

Prevention of varicose veins

Varicose veins do not get cured on their own. To some extent, it could be helpful to adopt a few lifestyle habits to increase blood flow from legs. As a result, you can keep your varicose veins under control, so they don't get worse.

Some of the lifestyle changes for the prevention of varicose veins are as follows:

• Do not stand for long periods.
• Take care of BMI (body weight) to lessen the pressure on the leg veins.
• Indulging in regular exercise to strengthen the veins, circulation and leg strength. 
• Avoid cross legging while sitting, and make a habit of raising your legs when resting.
• Wear compression stockings to improve circulation

Diagnosis of Varicose Veins

Diagnoses of varicose veins is based on it's appearance that the diagnostic process basically include physically examination by primary care physician followed by few diagnostic tests to assess the complications developed due to severity of varicose veins.

Some of the physical examination done are:

• Examining the veins and its surrounding areas 
• Checking for the symptoms like swelling, heat, or redness 
• Checking the pulse close to varicose veins to confirm the proper blood flow

Some of the diagnostics test done to diagnose the severity of varicose veins are: 

• Ultrasound scan (Doppler or Duplex scan): To check the structure and functionality of vein walls and valves.
• Complete Blood Count (CBC): This test is done on the blood taken from the veins to understand the infection caused due to varicose veins.

Varicose Veins Treatment

When it comes to varicose veins treatment, there are many treatment options available based on the condition of the patients and the severity of the disease. If the patient medical condition is not fit for the definitive treatment, few conservative treatment options are recommended to manage and relieve the symptoms. 

Some of the conservative treatment options are:

• Compression stockings 
• Lifestyle changes 
• Medicines

Based on the diagnosis and severity, definitive treatment options are recommended. Traditional surgeries and minimally invasive techniques/procedures are available to treat varicose veins.

Some of the minimally invasive procedures to treat varicose veins are:

• Endovenous Laser Ablation Therapy
• Radiofrequency Ablation 
• Microwave Ablation 
• Sclerotherapy
• Superglue
• MOCA
• Varithena 
• Steam 
• The V-Block
• LAFOS

Hormonal factors play a major role rather than the pressure of a growing uterus as these are more commonly seen during the first three months of pregnancy. Varicose veins during pregnancy can be prevented by some measures like avoiding prolonged sitting or standing, avoiding cross-legging, sleeping towards the left side (to decrease pressure on veins), avoiding tight clothes, and wearing compression stockings.

Are varicose veins a sign of heart disease?

Varicose veins are not directly a sign of heart disease. Artrerial disease is commonly associated with heart disease rather than venous disease. If untreated varicose veins are complicated by the formation of clots in the veins and if these clots migrate to lung veins, this can indirectly increase the workload of the heart and can cause heart problems.
