Answer:
Anaemia is the major blood related disease whose symptoms can include the following.
1- weakness
2- tiredness
3- pale coloured skin
4- cold extremities
5- irritation
Step-by-step explanation:
Anaemia is defined as the condition which arises due to lack of red blood cells. Red blood cells contain protein, haemoglobin, whose major constituent is iron. Human body uses iron to produce red blood cells in the bone marrow.
This haemoglobin helps red blood cells to transport oxygen to all the parts of human body. Oxygen gets attached to the haemoglobin and is carried all over the body. This oxygen is necessary for the cells of human body to function properly and survive.
Anaemia can be said to occur due to the lack of iron in human body. Lack of iron results in lack of red blood cells which results in decrease in oxygen supply to all the parts of the body.
Lack of oxygen hampers the normal functioning of human body as described below.
1- Capacity to work reduces and causes easy tiredness.
2- Weakness increases due to lack of iron.
3- The skin changes its colour, loses its shine and becomes yellowish showing lack of red blood cells.
4- The body temperature is also affected due to lack of oxygen. Hands and legs become cold.
5- Irritation increases. The patient becomes irritated easily due to weakness and fatigue.
Reasons for risk of anaemia
1- Disorder of intestine affects intake of nutrients by the small intestine. This increases chances of anaemia.
2- Menstrual cycle results in loss of blood. This also increases the chances of getting anaemia.
3- Anaemia can be hereditary. It can be genetically acquired.
4- Improper diet including heavy intake of coffee and tea also leads to Anaemia.
The severity of anaemia can vary from mild to severe. Treatment can be in the form of supplements for mild anaemia to medical procedures in case of severe anaemia.
