The legs are one of the most important parts of the human body. They help us perform daily tasks such as walking, running, and jumping. However, many people suffer from various health issues that affect their legs.

Here are seven common health issues visible in legs:.

1. Varicose Veins

Varicose veins are blue or purple swollen veins that are visible on the surface of the skin. They occur when the veins are not functioning properly and blood flow becomes restricted or reversed. This causes the veins to become enlarged and twisted.

When blood flow is restricted, it can cause a buildup of pressure in the veins. This leads to the veins becoming swollen and painful. In severe cases, the veins can rupture, leading to bleeding.

Varicose veins are most common in women and can be caused by obesity, pregnancy, or genetics.

2. Deep Vein Thrombosis (DVT)

Deep vein thrombosis (DVT) is a condition in which blood clots form in the deep veins of the legs. This can cause pain, swelling, and warmth in the affected leg.

In some cases, the blood clots can break off and travel to the lungs, causing a pulmonary embolism.

DVT is most commonly caused by immobility, such as during long flights or bed rest. Other risk factors include obesity, smoking, and hormonal birth control.

3. Peripheral Artery Disease (PAD)

Peripheral artery disease (PAD) is a condition in which the arteries in the legs become narrowed or blocked. This can cause leg pain, cramping, and fatigue. PAD can also increase the risk of heart attack and stroke.

PAD is most commonly caused by a buildup of plaque in the arteries. This can occur due to smoking, high blood pressure, high cholesterol, or diabetes.

4. Osteoarthritis

Osteoarthritis is a type of arthritis that affects the joints. It occurs when the cartilage that cushions the joints begins to break down. Osteoarthritis can cause pain, stiffness, and limited range of motion in the affected joint.

It is most commonly found in the knees, hips, and ankles.

Osteoarthritis is most commonly caused by wear and tear on the joints over time. Other risk factors include obesity, injuries, and genetics.

5. Rheumatoid Arthritis

Rheumatoid arthritis (RA) is a chronic autoimmune disorder that affects the joints. It causes inflammation and damage to the joints, which can cause pain, swelling, and stiffness. RA can also cause fatigue, fever, and weight loss.

While RA can affect any joint in the body, it is most commonly found in the hands, wrists, and feet. RA is most commonly caused by a combination of genetic and environmental factors.

6. Shin Splints

Shin splints are a common overuse injury that affects the lower legs. They are most commonly found in people who participate in activities that involve repetitive impact, such as running or jumping.

Shin splints cause pain and tenderness along the shin bone.

Shin splints are most commonly caused by overuse or improper technique during physical activity.

7. Stress Fractures

Stress fractures are small cracks in the bones that are most commonly found in the feet and lower legs. They are most commonly found in people who participate in high-impact activities, such as running or gymnastics.

Stress fractures cause pain and swelling in the affected area.

Stress fractures are most commonly caused by overuse or improper technique during physical activity.
