9. Heart palpitations
Increased heartbeats will also be experienced due to insufficient amounts of oxygen to the heart. The increased pounding is due to the fact that the heart is being overworked as it is forced to make do with the small amounts of oxygen present in the body. An overworked heart can lead to irregular heartbeats, enlargement, heart murmurs, and in worst cases heart failure which normally happens if you have been battling anemia for a very long time.
Iron in the red blood cells helps in the circulation of oxygen to all the body parts and helps regulate cell growth. The center of a red blood cell is made up of hemoglobin, which is an iron-rich protein. As the blood moves through the lungs, oxygen molecules normally attach themselves to the iron component of hemoglobin. When the blood leaves the lungs, it then releases oxygen to all the body cells and tissues and removes any carbon dioxide. If the blood does not have enough iron to create hemoglobin, the new red blood cells produced will be unhealthy and unable to pick up and deliver oxygen properly.
When the red blood cells are unhealthy and cannot adequately bind oxygen, the body cells and tissues become starved of oxygen. This results in the heart pumping much harder than normal to send out more red blood cells for oxygen transport, to make up for the missing oxygen in the cells and tissues. This pressure and stress on the heart result in heart palpitations and abnormal heartbeats. However, no matter how hard the heart beats, without enough healthy red blood cells, the body tissues will still lack oxygen.
Anyone that usually has heart problems and experiences heart palpitations and irregular heartbeats should have their iron levels checked since iron deficiency can worsen the existing heart problems.
