Circulation problems refer to conditions that impair the normal flow of blood through the arteries and veins, reducing the delivery of oxygen and nutrients to tissues. These issues commonly result from narrowed or blocked blood vessels due to atherosclerosis, blood clots, peripheral artery disease, diabetes, or heart disorders. Symptoms may include cold hands or feet, numbness, tingling, swelling, leg cramps during walking, fatigue, slow-healing wounds, or changes in skin color. Poor circulation can increase the risk of serious complications such as tissue damage, infections, heart attack, or stroke if left untreated. Management typically involves addressing underlying risk factors through lifestyle changes, medications, improved physical activity, and, in some cases, medical procedures to restore healthy blood flow.
