Iron is needed to produce haemoglobin, which is the part of the blood that carries oxygen throughout the body. A lack of haemoglobin means less oxygen available to be utilised by cells for energy
Anemia, meaning lack of blood, causes a person to have a fewer amount of blood cells. The few amount of blood cells means less oxygen and every part of your body needs oxygen in order to move or survive.
Anemia is either caused by lack of red blood cells for various reasons, or due to iron deficiency. Iron allows red blood cells to carry oxygen to your body. If you don't have as many red blood cells to carry the oxygen, you will feel more tired due to less oxygen to your brain and muscles. If you don't have enough iron to attach oxygen to the red blood cells, same result. Less oxygen, less energy.
Because there is lack of oxygen in the red blood cells.
Lack of Iron can cause a deficiency known as anaemia.
With each bout of fever the patient have a batch of red blood cells destructed. He gets hemolytic anaemia. That makes him to have less oxygenation of tissue and so he feels tired and weak.
Sufferers have less haemoglobin in the blood which means their blood carries less oxygen than normal. If your organs and brain in particular don't get much oxygen then they cannot create energy causing a perceived fatigue.
In my case it is "chronic anaemia" where "chronic" means "lasting for a long time". It can also be called "pernicious anaemia". The problem occurs when the body cannot make the B12 vitamin from the food which has been digested, so the alternative is to have a B12 injection every 3 months. One effect of lack of B12 is that you become very tired much more easily.
He gets tired veru easily
If they're stupid , self-centered or mean, I get tired of them in 10 min.
Morpheus was able to bring sleep to the tired, the suffering, and to those in pain.
It is generally not normal to always feel tired, especially if you are a teenager. You should consult a doctor.
You can't run and get tired easily or have a huge Belly
Sun makes people more tired . ^^
as people run they tend to carry their whole weight along with them and so this makes it harder on fat people to run as they have to carry their weight with them which makes them get tired easily and so they cannot run.
because if they have fewer red blood cells then they will not be able to absorb as much oxygen (what with haemoglobin and all) this means they must breath more and this, well, is tiring. also respiration requires more oxygen than anaemic people can supply
