Varicose Veins
Swollen, twisted veins, usually in the legs, that look blue or dark purple and may bulge under the skin. They occur when the small valves inside the veins weaken, allowing blood to pool.
⚠ Seek medical attention if:
A leg that suddenly becomes painful, swollen, warm, or red (possible blood clot); skin ulcers or open sores near the ankle; bleeding from a varicose vein; or hard, tender, discoloured skin around a vein. Seek prompt medical care for these.
Lifestyle factors
Prolonged standing or sitting, lack of movement, carrying excess weight, pregnancy, and a family history; risk also rises with age
Nutritional factors
Low-fibre diets that lead to constipation and straining, inadequate hydration, and diets low in flavonoid-rich fruits and vegetables that support vein health
Possible medical causes
Weakened or damaged vein valves (venous insufficiency), pregnancy, previous blood clots (deep vein thrombosis), and pelvic vein problems
Next steps
See a GP if varicose veins are painful, if the skin around them changes, or if they affect daily life, as treatments are available. Seek urgent care for bleeding or signs of a clot.

Cautions: Increase dose gradually and drink plenty of water to avoid worsening constipation or blockage risk
May support circulation and healthy blood flow
