Varicose veins: everything you didn’t know

Swollen and enlarged veins are common in the population, and they can be painful and uncomfortable for some people. Varicose veins affect up to 20% of individuals, and they don’t just affect the elderly; younger people and animals can also have them. The issue that troubles women the most is varicose or expanded veins. Even if they frequently merely indicate aesthetic issues and don’t interfere with anybody else, some people can nevertheless experience pain and discomfort, which can eventually result in major complications. Perhaps you have experienced heaviness, swelling, and occasionally pain in your legs in the past, and the explanation may simply be dilated veins.

Varicose veins, which are defined as stretched surface veins, are most frequently found on the foot. Most frequently blue or purple in appearance, they are typically big, bloated, and winding. Their appearance varies depending on the severity of the disease and can range from microscopic arachnoid veins to a sickly, clearly pronounced hump with the appearance of open wounds (ulcers), which represents the most challenging stage of the disease.

The 7 stages of illness are often distinguished by clinical examination:
  • Stage 0: There are no apparent characters or varicose veins at all.
  • Stage 1 – telangiectasias (tiny, arachnoid) are observed, measuring up to 1 millimeter wide, venules (up to 2 millimeters wide), or reticular veins (up to 4 millimeters wide), or redness/swelling of the eye or ankle.
  • Stage 2 – Varicose veins (saccular), which measure more than 4 mm broad.
  • Stage 3 – Edema is visible (swollen leg), but the skin has not changed.
  • Stage 4 – Venous disease-related skin abnormalities such as pigmentation, venous eczema, lipodermatosclerosis, or induration and blackened skin, are visible.
  • Stage 5 – skin changes are visible, and the wound (ulcer) has healed.
  • Stage 6: Skin alterations with open ulcers are present (wounds).


Clinical symptoms and indicators that indicate a patient are typically caused by reflux, vein blockages, or a combination of these. Reflux (return blood) in the veins is caused by damaged venous valves, and healthy people’s roles are to promote blood flow in the direction of the heart and stop recurring blood flow.

Expanded veins, however, have broken valves, which results in blood retention or when blood otherwise direction, which deteriorates clinical pictures and introduces subjectivity. The most frequent venous thrombus, which might be new or old, is what causes the obstruction (blockage) in the veins themselves.

All veins’ function is to return blood to the heart. Their one-way sideburns are essential to preventing blood divination because they “work” against gravity with their feet as it withers on. Muscles in the foot also assist because of their own movement, such as walking, which acts as a pump to push veins and send blood upwards or back toward the heart. The valves cannot function as needed if the vein wall loses its flexibility. Their blood spreads and swells because it is delayed in them.
