Studies have shown that about 1% of children under 10 years old and 10 to 15% of children especially in high school have varicose veins.
The fact that children can develop varicose veins adds a new worry for parents striving to protect their children's physical and mental health in today's complex world. Contrary to common belief that varicose veins only affect adults this condition can impact children too. Fortunately the likelihood increases with age so only a small percentage of children are at risk. Studies show about 1% of children under 10 and 10-15% of teens especially in high school have varicose veins. Recognizing risk factors, early diagnosis and proper treatment help parents take the best action if faced with this concern.
You might think varicose veins in children stem from playfulness or excessive jumping but the condition has more serious causes:
Genetic and Congenital Factors: Abnormalities or defects in the vascular system or venous valves which prevent blood backflow in the legs can be genetic or developmental during fetal growth. Congenital varicose veins or abnormal blood vessel development put children at risk.
Specific Diseases: Conditions like blood clotting disorders, Klippel-Trénaunay syndrome (affecting blood vessels), venous tumors or vein inflammation make children more susceptible.
Lifestyle and Nutrition: Insufficient activity, tight clothing (especially shoes or stockings), poor diet with processed foods, sweets, fast food, low fiber, fruits and vegetables contribute. Though children often prefer unhealthy foods, creative cooking can encourage healthier eating.
Injury or Trauma: Falls, accidents or sports injuries like soccer kicks can cause venous trauma. If you notice pain, heaviness, fatigue, inflammation or bulging veins after injury consult a doctor.
Obesity: Modern diets and screen time have increased obesity in children and teens. Excess weight pressures veins leading to spider veins or reticular varicose veins due to inflammation.
Hormonal Changes: Hormonal shifts especially in teen girls during puberty affect vein function or valve performance. Fluctuations in estrogen and progesterone weaken vein walls and reduce elasticity.
Prolonged Standing or Sitting: Children or teens in activities requiring long standing or sitting risk vein health. Teach them to change positions every 30 minutes for prevention.
Describing pain or symptoms to parents or doctors can be challenging for children especially since symptoms may be milder and swelling or bulging can change with growth. Symptoms may include:
Leg pain or discomfort
Burning or itching
Muscle cramping or tightness
Fatigue and heaviness
Swelling and inflammation
Bulging, twisted veins
Skin discoloration
Despite symptoms, precise diagnosis is needed:
Clinical Exam: A doctor can detect varicose veins through physical examination of the child or teen.
Doppler Ultrasound: This non-invasive imaging, performed on the skin, assesses blood flow, vein structure and valves. It’s one of the most accurate methods for diagnosing varicose veins in children and teens.
Blood Tests: A varicose vein specialist may order blood tests to check clotting issues or other underlying conditions.
Fortunately severe varicose veins requiring treatment are rare in children. However treatment must be cautious and by an experienced specialist as children's vascular and venous systems are still developing. Focus on prevention first.
Prevent varicose veins in children with:
Healthy diet
Regular exercise and activity

Weight control
Regular check-ups especially for those at higher risk due to factors mentioned.
Avoiding pressure on leg veins like prolonged standing or sitting or high-impact sports.
Elevating legs above heart level several times daily
Appropriate clothing and shoes
Sunscreen and avoiding prolonged sun exposure especially for infants under 6 months
If prevention fails, medical intervention is needed:
Compression stockings
Nonsteroidal anti-inflammatory drugs
Lifestyle modifications
Beneficial activities like walking, swimming or light cycling
Based on varicose vein type, severity, child's overall condition and age:
Sclerotherapy: A common treatment injecting a chemical into varicose veins to close and eliminate them.
Laser Therapy: Uses laser beams to block and remove varicose veins.
Phlebectomy: Small incisions remove varicose veins. Most surgeons believe removing varicose veins is not ideal for children or young adults.
Varicose veins in children can affect mental health and social life just as in adults. Visible leg veins may reduce confidence or lead to social withdrawal due to embarrassment. If severe symptoms like pain, inflammation or ulcers can limit play or activity, impacting emotional well-being over time.
While varicose veins in children are rare, take risk factors and symptoms seriously. For diagnosis and treatment, act promptly and consult an experienced varicose vein specialist.
Genetics, tight clothing (especially on thighs and calves) and obesity are key causes of spider veins in children.
Surface laser therapy applied through the skin can treat spider veins. For children's sensitive skin use a specialist and appropriate device to avoid burns or spots.
Yes, as noted in the article, genetics is a major cause.
Yes, untreated severe cases can lead to venous ulcers, bleeding or rarely, blood clots.
Varicose veins typically become more common after age 30 but can start earlier due to genetics, congenital defects, hormonal changes, disease, injury or unhealthy lifestyle.
