Your body is a complex network of nerves, tissues and other structures that relies on countless chemical reactions to function normally. It needs a constant supply of heat, nutrients and oxygen to carry out the necessary chemical reactions for healthy functioning. The blood is responsible for transporting these ingredients to each part of the body. While blood fulfills many other functions, the task of supplying organs with the nutrients and oxygen is definitely the most important.
Poor blood circulation is bad for you because it forcefully shuts down your body—by shutting down the supply of oxygen and nutrients to your organs. The symptoms of poor circulation depend on which part suffers from it the most. Some people have poor circulation in their legs, others have it in the lungs or the brain—each condition has its unique symptoms.
There are, however, precursors to poor blood circulations which are observed across all patients that worsen to fall under the conditions mentioned above if left untreated.
1. Cold Hands and Feet
Blood is responsible for maintaining a constant body temperature— cutting off blood circulation to any of your hands or feet will automatically make them colder. Since there isn’t any blood in the region to warm it up, it becomes uncomfortably cold. People who often complain of cold hands and feet are likely suffering from a blood circulation problem that they should get checked.
2. Shortness of Breath
Shortness of breath indicates oxygen deprivation which is forcing your lungs to pull in more air for more oxygen. If you find yourself catching your breath even though you haven’t exercised or engaged in any physically strenuous exercise, it might indicate a circulation problem from pulmonary hypertension (PH). PH is caused by poor circulation into the left side of your heart and the body, which lowers blood oxygen levels and makes you short of breath.
3. Fatigue and Lethargy
Fatigue and lethargy is caused by circulation problems in your muscles and the brain. Oxygen deprivation from circulation problems in the brain makes it difficult to concentrate and makes you sleepy. Similarly, circulation problems in the muscles reduce glucose oxidation rates necessary for muscle movement.
4. Muscle and Tissue Atrophy
The chemical composition of the blood also includes many nutrients responsible for muscle formation and maintenance of muscle mass and tissue health. Diabetic Macular Edema is one example of poor circulation affects the tissues of the human eye and causes vision loss or blindness in diabetic patients.
