What Causes Varicose Veins?

Varicose veins occur due to the malfunction of vein valves, resulting in backward blood flow (venous insufficiency).

  • Genetic predisposition
  • Prolonged standing or sitting
  • Sedentary lifestyle
  • Obesity (excess weight puts pressure on veins)
  • Pregnancy (increased pressure on veins)
  • Hormonal changes (more common in women)

What Are the Symptoms of Varicose Veins?

  • Visible blue-purple veins on the legs
  • Pain, burning, and heaviness
  • Swelling (edema)
  • Night cramps and restless legs
  • Itching and skin discoloration

If untreated, varicose veins can cause serious problems like bleeding, vein blockages, and leg ulcers.

What Are the Types of Varicose Veins?

1. Spider Veins (Telangiectasia)
  • Thin, red-purple dilated veins
  • Usually a cosmetic concern, but may cause discomfort
2. Reticular Varicose Veins
  • Moderately thick, blue-purple veins close to the skin
3. Large Varicose Veins (Enlarged Main Veins)
  • Bulging, prominent, twisted veins
  • If venous insufficiency progresses, leg ulcers and skin changes may occur

How Is Varicose Vein Treatment Done?

1. Non-Surgical (Minimally Invasive) Treatments

Most preferred methods for mild to moderate varicose veins:

1. Sclerotherapy
  • A special solution is injected into the vein to close it
  • Effective for spider and medium-sized veins
2. Laser or Radiofrequency Ablation (EVLA / RF)
  • Laser or RF energy is delivered to the vein to close it
  • Effective in large varicose veins and venous insufficiency
3. Foam Sclerotherapy

Uses a more concentrated foam version of sclerotherapy, effective for closing larger veins.

4. Medical Compression Stockings
  • Supports circulation, reduces swelling and pain
  • Does not cure varicose veins, only relieves symptoms

2. Surgical Treatments (For Advanced Varicose Veins)

  • Stripping Surgery: Surgical removal of large varicose veins. Not commonly used anymore.
  • Microphlebectomy: Removal of varicose veins through small incisions.

Tips for Preventing and Controlling Varicose Veins

  • Avoid standing or sitting for long periods
  • Do regular walking and leg exercises
  • Rest your legs elevated
  • Avoid tight clothes and high heels
  • Maintain a healthy weight
