What are the symptoms of thromboangiitis obliterans?

Thromboangiitis obliterans is a disease that affects the blood vessels of the lower extremities. If you experience symptoms, please seek medical attention immediately. It usually manifests as leg pain, limping, and localized skin pallor or purpleness. These symptoms are caused by a lack of blood flow, which results in insufficient blood supply. This disease is more common in long-term smokers, so quitting smoking is the key to prevention.

The basis of this disease is that the inner wall of the blood vessels is irritated for a long time, forming blood clots, which are like blockages in the pipes, restricting blood flow. In the long run, this may lead to tissue hypoxia and necrosis, just like a clogged water pipe will cause plants to wither due to lack of water. Therefore, early identification is crucial, especially when you feel unexplained pain while walking, you need to be vigilant.

In addition to leg symptoms, patients sometimes experience tingling or numbness, and if the local temperature drops, it may mean that circulation is further obstructed. Pain increases after activity, which is often relieved by rest, because rest reduces the muscle's demand for blood oxygen, but rest alone cannot cure the cause.

A reasonable lifestyle is extremely important for the management of this disease. Keep your lower limbs warm, avoid standing for long periods of time, and exercise moderately to promote blood circulation. The doctor may recommend medication or surgical intervention based on the condition. Regular physical examinations, careful diet, and control of blood sugar and blood lipid levels are all effective measures. If symptoms persist or worsen, be sure to seek medical help immediately.
