10. Iron-Deficiency Anemia
Anemia is a condition resulting from not having enough iron in your blood. Your body requires iron to create hemoglobin, a protein in red blood cells that allows it to carry oxygen to the blood vessels. Less iron means less opportunity for this oxygen-carrying purpose, so a person with anemia will feel fatigued. Unusual tiredness is usually the first symptom of anemia, and it’s also a common symptom in those who don’t have enough iron in their blood without actually being anemic.
Without this hemoglobin, your heart has to work overtime to provide enough oxygen to the rest of the blood, further increasing fatigue. A reduction of hemoglobin also means that there is not enough oxygen getting to the brain, impacting memory, mood, and concentration. You could detect anemia at home if you look at the inside of your bottom eyelid or gums; if they appear paler than usual, you could have anemia. You should seek the advice of a doctor immediately.
