The blood circulatory system, also called the cardiovascular system, is an organ system that permits blood to circulate and transport nutrients (such as amino acids and electrolytes), oxygen, carbon dioxide, hormones, and blood cells to and from cells in the body to nourish it and help to fight diseases, stabilize body temperature and pH, and to maintain homeostasis. The study of blood flow is called hemodynamics.

Symptoms of Poor Blood Circulation

Bad circulation is not common especially in young persons. It often targets the elderly, middle aged, and those suffering from different conditions including diabetes and atherosclerosis. Bad circulation is known as a silent killer, and it presents itself with different symptoms.


Signs and symptoms of bad circulation develop over time. This is why you should learn how to listen to your body and seek early diagnosis.

1.Swollen Feet. This is a common sign of bad circulation, and it occurs because normal functioning of the kidneys is interrupted. When poor blood circulation occurs, renal arteries tend to accumulate fats causing a pool of blood in the legs. Therefore, when you notice any form of feet swelling, it is important that you raise the legs above the heart level. The swelling will subside. If it doesn’t, it is critical that you seek medical advice.

2.Cold Feet and Hands. Proper blood flow helps in regulating body temperature. However, when blood flow is interrupted, the body cannot maintain its normal temperature and in most cases, cold extremities will be experienced in the legs and feet. Heat extremities can also occur in some individuals.

3.Skin Discoloration or Cyanosis. Cyanosis occurs when there is an inadequate amount of oxygen in the blood. Bluish discoloration will occur in the toes and fingers, and they will appear with bluish tints. In babies, the condition is always the first sign of congenital heart diseases and needs urgent medical attention.

4.Fatigue. When poor blood circulation occurs, different body organs will struggle to carry out their normal duties. Less oxygen as well as essential nutrients that the body needs will not reach the muscles causing fatigue. This is often accompanied by muscle cramps and pain in the legs. Some people will suffer from breathlessness and lack of stamina.

5.Poor and Slow Healing. With proper blood flow, the immune system will always enhance fast healing of wounds. However, when blood flow is interrupted, the immune system is weakened. The injured part of the body will not receive sufficient blood. This means that even small and minor injuries will take a long time to heal.

6.Loss of Appetite. Sufficient blood in the liver boosts your appetite. With bad circulation, you won’t feel like eating and with time, you start losing weight. Therefore, when you lose appetite, it is important that you seek proper diagnosis because you could be suffering from bad circulation.

7.Constipation. This is also one of the first signs of poor blood circulation. The body system slows down when its normal functioning is interfered with due to bad circulation. Your digestive system will gradually slow down causing constipation. In severe cases, you will suffer from other gastrointestinal disorders.

8.Varicose Veins. Varicose veins will appear in the legs when bad circulation occurs. They are often itchy and cause irritability. In extreme cases, varicose veins will be very painful. It is, therefore, important that you wear compression stockings to enhance proper blood flow.

9.Numbness. When you stand or sit for a long time, blood circulation is interrupted. You will experience a tingling sensation and numbness in different parts of the body. When numbness occurs, it is essential that you seek medical assistance because it could lead to heart disease.

10.Dry Skin. Bad circulation also causes dry skin, hair loss and brittle nails. This is because these parts no longer receive essential nutrients in the rightful amounts for them to function normally.

11.Dizziness and Memory Loss. In extreme cases, bad circulation causes dizziness as well as memory loss. This is based on the fact that it bad circulation prevents supply of oxygen and nutrients to the brain.
