What would be the consequences of a deficiency of haemoglobin in our bodies?

Hemoglobin deficiency, also known as anemia, is characterized by a decrease in the number of red blood cells or a lower concentration of hemoglobin in the blood. Hemoglobin deficiency can have serious consequences for our bodies, some of which are listed below:

1. Hemoglobin deficiency deprives the body of the oxygen it needs, leading to persistent fatigue, weakness and shortness of breath.
2. Due to inadequate oxygen supply to the brain we may may experience difficulty concentrating, memory problems, and decreased mental alertness.
