When your circulatory system is working as it should, your organs and body parts get the needed amount of oxygen and nutrients from your blood. But if there’s a problem in the circulatory system, the blood flow can become reduced and cause a whole host of various symptoms throughout your body. Although it’s possible to have poor blood circulation and not even know there’s a problem, some symptoms are usually present, but many people simply don’t pay attention to them. This is why it’s vitally important to know the symptoms that poor blood circulation can produce in order to avoid serious complications, such as a heart attack or stroke.
Below, we list a few possible causes of poor circulation and the symptoms it may cause.
Possible causes of poor blood circulation
One of the most common causes of poor circulation is atherosclerosis, in which the arteries become narrowed and stiff due to plaque buildup. The plaque can accumulate in any artery in your body. Common conditions caused by atherosclerosis include peripheral artery disease (affecting the limbs, usually the legs) and coronary artery disease (plaque buildup in heart arteries).
Other causes of poor blood circulation include the following:
- poorly controlled diabetes;
- Raynaud’s disease;
- varicose veins;
- heart failure.
8 signs and symptoms of poor circulation
Reduced circulation can manifest in the following signs and symptoms:
1. Problems with thinking and memory
If the blood flow to the brain is inadequate, you may notice symptoms such as lowered ability to pay attention, problems with memory, and inability to gather your thoughts. Over time, poor blood circulation in the brain may even lead to vascular dementia.
2. Unpleasant sensations in your limbs, especially legs
If blood circulation in your limbs is impaired, you will likely get symptoms such as tingling, numbness, pain, and cramps. Also, your limbs may feel colder than the rest of the body. These symptoms tend to get more severe and frequent over time.
3. Leg ulcers and poor healing of small wounds and bruises
Poor blood circulation in your limbs (especially the legs) can lead to slow healing of bruises and small wounds. If blood flow is seriously reduced, it may even lead to ulcers.
4. Weakness and tiredness
Reduced blood circulation can cause you to feel generally weak and tired, even if you haven’t been doing anything.
5. Dark circles
