Unusual Fatigue
Unusual fatigue is one of the most common signs of anemia. It is also prevalent in those who simply do not have sufficient iron in the body, even when they have not received an official diagnosis. This symptom occurs when there is a deficiency of iron, which is necessary to produce haemoglobin. This protein is important for the transport of oxygen around the body. Without sufficient haemoglobin, muscles and tissues will get less oxygen, thus lacking energy to function. The heart also needs to work much harder to pump oxygen-rich blood. This makes you feel tired more than usual. Because fatigue is a very common health issue, it can be challenging to diagnose anemia just based on this sign. However, if it occurs with other symptoms mentioned in this post, anemia may be the possible cause. [1]
