Good blood circulation is essential for good health. Your blood helps transport nutrients and oxygen to every part of your body. Any problem with your circulatory system can lead to a variety of other health issues. If left untreated, it can cause serious damage to your brain, heart, liver, kidneys and limbs. You can have poor blood circulation for several reasons, with the most common being atherosclerosis, or “hardening of the arteries”, and peripheral artery disease (PAD). It can also be a result of other health problems like diabetes, heart disease, obesity or blood clots. Smoking, excess drinking, pregnancy and eating disorders can also make you more vulnerable to this condition. By knowing the symptoms of poor circulation, you can target the root cause and get it treated timely. It is important to consult a doctor when experiencing symptoms of circulation problems, as it can lead to a heart attack, a stroke and even death. Here are the top 10 warning signs of poor blood circulation 1. Swelling of Lower Extremities Mild cases of swelling in your feet can be due to sitting or standing in one position for long periods of time, high salt intake, malnutrition, obesity, aging, a sedentary lifestyle, premenstrual syndrome (PMS) and pregnancy. However, if you suffer from edema or swelling in your feet for quite some time, it may be because of poor blood circulation. Due to a lack of blood flow, the kidneys become unable to carry out the process of keeping fluid in the blood vessels where it belongs. This causes the fluid to leech out and settle into surrounding tissues, which leads to swelling. In extreme cases, poor circulation can also cause leg ulcers. When you notice any form of swelling in your feet, raise your legs above your heart level. The swelling will subside once the circulation improves. Consult your doctor if you have persistent or extreme swelling. 2. Numbness in Hands and Feet Feeling numb in certain body parts, especially in the extremities (hands and feet) can also be a sign of poor blood circulation. You can also have numbness due to constant pressure on your hands or feet, exposure to cold, temporary nerve compression, a sedentary lifestyle and a nutritional deficiency of vitamin B12 or magnesium. It can also be a symptom of carpal tunnel syndrome, diabetes, multiple sclerosis and an underactive thyroid. 3. Cold Hands and Feet Proper blood flow helps maintain a healthy body temperature. When blood flow is interrupted, the body cannot maintain its normal temperature, resulting in cold hands and feet. Due to poor circulation, blood is not able to travel easily to the furthest parts of your body, such as your fingers and toes. Reduced oxygen levels in the body’s cells can lead to cold extremities. Rubbing the affected area is a natural response to encourage blood to flow more quickly to those areas. Other common causes of cold hands and feet are an underactive thyroid, Raynaud’s syndrome and peripheral neuropathy. If you have cold extremities without any known reason, consult your doctor to find out the exact cause.
