What Is Claudication?
Claudication is muscle pain that happens during physical activity, most often while walking. The discomfort usually affects the calves, thighs, or buttocks and improves with rest.
This condition is commonly caused by peripheral artery disease (PAD), which happens when narrowed arteries reduce blood flow to the legs. Over time, symptoms may become more noticeable and limit daily activities.
Several factors can increase the risk of developing claudication, including:
- Smoking
- Diabetes
- High blood pressure
- High cholesterol
- Obesity
- Limited physical activity
- Older age
- Family history of vascular disease
Because PAD affects blood vessels throughout the body, claudication may also increase the risk of heart attack or stroke.
Symptoms
Claudication symptoms are caused by muscles not getting enough oxygen-rich blood during movement.
Common symptoms include:
- Cramping or aching in the legs when walking
- Muscle heaviness or fatigue with activity
- Pain that improves after resting
- Limping or difficulty walking long distances
- Cold feet or legs
- Slow-healing sores or skin changes
In more advanced cases, pain may continue even while resting.
How Is It Diagnosed?
Healthcare providers diagnose claudication by reviewing symptoms, checking circulation, and evaluating blood flow in the legs.
One common test is the ankle-brachial index (ABI), which compares blood pressure in the arms and ankles. Ultrasound and imaging studies such as angiography may also help locate narrowed or blocked arteries.
How Is It Treated?
Treatment for claudication usually begins with lifestyle changes aimed at improving circulation and lowering cardiovascular risk.
Conservative treatment may include:
- A structured walking or exercise program
- Quitting smoking
- Healthy eating habits
- Managing blood pressure, cholesterol, and diabetes
- Weight management
Medications may be prescribed to improve blood flow or reduce the risk of blood clots.
If symptoms become severe or circulation is significantly reduced, procedures may be needed to restore blood flow. These treatments can include angioplasty, stent placement, or bypass surgery. With ongoing care and healthy lifestyle changes, many people are able to improve their symptoms and stay active.
