Varicose veins, a common yet often overlooked condition, afflict many individuals across the UK. The National Institute for Health and Care Excellence (NICE) reveals that nearly one-third of the population will develop visible varicose veins in their lower limbs. While the majority are benign, some can lead to discomfort or potential health risks. The NHS offers varying levels of treatment, which we delve into below.
Defining Varicose Veins
As the NHS describes, varicose veins are enlarged, swollen veins often seen on the lower limbs. Characteristically blue or purplish, these veins protrude from the skin, presenting a bumpy texture. Though similar in appearance to spider veins, varicose veins are distinct, usually being more significant and occasionally causing pain or discomfort.
These veins arise due to dysfunctional valves within our circulatory system. These valves, which ensure unidirectional blood flow towards the heart, may falter, causing blood to pool and leading to vein enlargement.
Risk Factors for Varicose Veins
- Gender Predilection: Women are more susceptible, with hormonal influences believed to weaken vein walls, further exacerbated during pregnancy.
- Genetics: A family history increases one’s risk.
- Obesity: Excessive weight can exert added pressure on veins.
- Ageing: Vein elasticity diminishes over time.
- Prolonged Standing: Occupational hazards or habits can hinder optimal blood circulation.
- Medical History: Individuals with blood vessel abnormalities or prior blood clots have heightened susceptibility.
Implications of Varicose Veins
Varicose veins are graded based on severity:
- Grade 1: Cosmetic concern only.
- Grade 2: Mild swelling.
- Grade 3: Increased discomfort, especially when standing.
- Grade 4: Potential for inflammation, or venous eczema.
- Grade 5: Severe skin changes.
- Grade 6: Possibility of venous ulcers, which can be painful.
Though a minority, up to 6% of varicose vein sufferers might develop venous ulcers, as per NICE’s estimation.
NHS’s Stance on Treatment
Varicose veins can be indicative of underlying circulatory issues. Hence, it’s prudent to consult a physician. However, NHS’s treatment criteria, especially for Grade 1 and 2 varicose veins deemed cosmetic, have become stringent.
Historically, in 2009-2010, NICE reports that the NHS conducted 35,659 varicose vein procedures. However, to curtail “unnecessary procedures,” NHS revised its treatment guidelines. This translates to fewer individuals receiving varicose vein treatments on the NHS.
NHS’s Approach to Treatment
The NHS’s primary recommendation for Grade 3 varicose veins includes wearing compression stockings, elevating the affected limbs, and regular exercise. Following six months of consistent stocking usage, if discomfort persists, more extensive treatments might be considered:
- Endothermal Ablation: Seals off varicose veins using energy.
- Sclerotherapy: Foam injections cause scarring, sealing the veins.
- Ligation and Stripping: A surgical procedure where problematic veins are tied off and removed.
In conclusion, while varicose veins are widespread, the degree of medical intervention varies based on severity. With the NHS continually updating its treatment criteria, being informed of the available options is crucial for those affected.
