How do you account the lack of energy people who are anaemic?

Anemia often leads to a lack of energy due to reduced levels of hemoglobin, which decreases the blood's ability to carry oxygen to tissues and organs. This oxygen deficiency can result in fatigue, weakness, and diminished physical performance. Additionally, the body may divert energy resources to compensate for the lack of oxygen, further contributing to feelings of lethargy. Addressing the underlying causes of anemia, such as iron deficiency or vitamin B12 deficiency, is essential for restoring energy levels.
