Varicose veins are enlarged, twisted veins that can appear blue or purple. They are most common in the legs, but can also occur in other parts of the body, such as the rectum (haemorrhoids).
Veins and Blood Flow
Veins are blood vessels that return deoxygenated blood to the heart. This is in contrast to arteries, which carry oxygenated blood away from the heart to the body.
There are three types of veins:
- Superficial veins: Located close to the surface of the skin, transport blood from the outer extremities like arms and legs back to the heart. Examples are the great and small saphenous veins.
- Deep veins: Located deeper inside muscles and surrounding bones. Transport blood from limbs and organs back to the heart. Examples are femoral and popliteal veins.
- Perforator veins: Connect the superficial and deep veins, allowing blood to flow between them.
Veins contain one-way valves that prevent the backflow of blood and rely on muscle contractions and breathing to pump blood back to the heart.
The superior and inferior vena cava are the major veins bringing deoxygenated blood back into the heart. From there, it goes to the lungs to pick up oxygen again before being pumped back out to the body.
Problems with veins include blood clots (deep vein thrombosis), varicose veins, chronic venous insufficiency and phlebitis. These can obstruct normal blood return from the periphery back to the heart and lungs.
Maintaining activity, ideal weight and proper compression stockings promotes healthy vein and blood flow.
What are varicose veins?
Varicose veins are enlarged, twisted veins that can appear blue or purple. They are most common in the legs, but can also occur in other parts of the body. There are many causes of varicose veins, including weak or damaged valves in the veins, increased pressure in the veins, standing or sitting for long periods, obesity, pregnancy, and family history. Varicose veins can cause pain, swelling, and itching. In some cases, varicose veins can lead to more serious complications, such as blood clots. There are several treatments available for varicose veins, including compression stockings, sclerotherapy, endovascular laser treatment, and surgery.
Varicose Veins Causes and Symptoms
Symptoms of varicose veins may include:
- Twisted, bulging veins that are dark purple or blue
- Swollen, achy legs
- Leg muscle cramping or throbbing
- Itchy or burning skin around the affected veins
- Pain that worsens after sitting or standing for long periods
- Skin discolouration or inflammation
- Hardened skin around the affected veins
- Leg fatigue or heaviness
If you're experiencing any of these symptoms, it's important to speak with your healthcare provider to determine the best course of treatment.
What causes varicose veins?
Varicose veins can be caused by many factors, including:
- Genetics: If your parents or other family members have varicose veins, you may be more likely to develop them as well.
- Age: As you get older, your veins can weaken and lose elasticity, making them more prone to bulging and twisting.
- Gender: Women are more likely than men to develop varicose veins, likely due to hormonal changes during pregnancy and menopause.
- Pregnancy: The increased blood volume and pressure on your veins during pregnancy can cause varicose veins to develop or worsen.
- Obesity: Excess weight puts added pressure on your veins, making it more difficult for blood to flow properly.
- Sitting or standing for long periods: When you sit or stand for long periods, blood can pool in your legs, increasing the likelihood of varicose veins.
- Injury: If you've had a leg injury, your veins may be damaged and more likely to develop varicose veins.
How can I tell if I have varicose veins?
If you have any of the following symptoms, you may have varicose veins:
- Visible bulges in the skin
- Pain, swelling, or itching in the legs
- Cramping in the legs
- Restless legs
- Dusky skin colour on the legs
What should I do if I think I have varicose veins?
If you think you have varicose veins, it is important to see a doctor. A doctor can diagnose varicose veins and recommend the best treatment for you.
How are varicose veins diagnosed?
A doctor can usually diagnose varicose veins by simply looking at them. In some cases, a doctor may order an ultrasound to confirm the diagnosis.
How can varicose veins be treated?
Fortunately, there are several effective treatments for varicose veins. Your healthcare provider may recommend one or more of the following:
- Compression stockings: These tight-fitting stockings can help improve blood flow and reduce swelling and discomfort.
- Sclerotherapy: This involves injecting a solution into the affected vein, causing it to collapse and fade over time.
- Endovenous laser treatment: This minimally invasive procedure uses laser energy to heat and seal off the affected vein.
- Vein stripping: This involves removing the affected vein through a small incision.
- Ambulatory phlebectomy: This minimally invasive procedure involves removing smaller varicose veins through tiny incisions.
In some cases, lifestyle changes such as exercising regularly, maintaining a healthy weight, and avoiding sitting or standing for long periods can also help reduce the appearance and discomfort of varicose veins.
How to Prevent Varicose Veins?
While some risk factors for varicose veins, such as age and gender, cannot be controlled, there are steps you can take to reduce your risk of developing varicose veins. These include:
- Maintaining a healthy weight: Excess weight puts pressure on the veins, which can lead to varicose veins.
- Staying active: Regular exercise, such as walking or swimming, can help improve circulation and reduce the risk of varicose veins.
- Elevating your legs: Elevating your legs above heart level for short periods throughout the day can help improve circulation and reduce swelling.
- Avoid prolonged sitting or standing: If your job requires you to sit or stand for long periods, try to take frequent breaks and move around when possible.
- Wearing compression stockings: If you have a family
What are the risks of varicose veins?
In most cases, varicose veins are not serious. However, in some cases, varicose veins can lead to more serious complications, such as blood clots.
Blood tests for varicose veins
There are no specific blood tests for varicose veins. However, your doctor may order some blood tests to rule out other conditions that can cause similar symptoms, such as deep vein thrombosis (DVT) or peripheral artery disease (PAD).
Some of the blood tests that your doctor may order include:
- Complete blood count (CBC): This test checks the number of red blood cells, white blood cells, and platelets in your blood.
- Sedimentation rate (ESR): This test measures the speed at which red blood cells settle to the bottom of a test tube. A high ESR can be a sign of inflammation.
- C-reactive protein (CRP): This protein is produced by the liver in response to inflammation. A high CRP level can be a sign of inflammation.
- D-dimer: This protein is produced when blood clots break down. A high D-dimer level can be a sign of a blood clot.
- Ankle-brachial index (ABI): This test measures the blood pressure in your ankles and arms. A low ABI can be a sign of PAD.
If your doctor suspects that you have varicose veins, they will likely perform a physical exam. During the exam, your doctor will look for enlarged, twisted veins in your legs. They may also ask you about your medical history and family history of varicose veins.
If your doctor diagnoses you with varicose veins, they may recommend lifestyle changes or treatments to help relieve your symptoms.
Varicose veins are a common condition that affects many people, particularly as they get older. While they can be unsightly and uncomfortable, there are many effective treatments available. If you're experiencing symptoms of varicose veins, speak with your healthcare provider to determine the best course of action for your individual needs. By taking steps to manage your varicose veins, you can improve your overall health and quality of life.
