What causes poor blood circulation?

As a medical professional with expertise in cardiovascular health, I can explain that there are several factors that can contribute to poor blood circulation. Here are some of the primary causes: 1. Peripheral Artery Disease (PAD): This is a common cause of poor circulation in the legs. PAD occurs when the peripheral arteries become narrowed due to atherosclerosis, which is the buildup of plaque in the arterial walls. 2. Atherosclerosis: As mentioned, this condition involves the hardening and narrowing of the arteries due to plaque buildup. This can restrict blood flow to various parts of the body, including the limbs. 3. Diabetes: High blood sugar levels can damage the blood vessels and nerves, leading to a reduced ability of the blood to flow properly. 4. Obesity: Excess weight can put strain on the circulatory system, making it harder for the heart to pump blood throughout the body. 5. Smoking: Smoking can damage the inner lining of the blood vessels, making them less flexible and more likely to become blocked. 6. Inactivity: A sedentary lifestyle can contribute to poor circulation as the muscles in the body do not pump blood as effectively. 7. Certain Medications: Some medications, particularly those that affect blood pressure or heart function, can also impact circulation. 8. Medical Conditions: Conditions such as Raynaud's disease, deep vein thrombosis (DVT), and blood clotting disorders can also lead to poor blood circulation. It's important to note that these are just a few potential causes. Proper diagnosis and treatment by a healthcare professional are essential for addressing poor blood circulation effectively.

Peripheral artery disease (PAD) can lead to poor circulation in your legs. ... In an associated condition called atherosclerosis, arteries stiffen due to plaque buildup in the arteries and blood vessels. Both conditions decrease blood flow to your extremities and can result in pain.
