Top Causes, Symptoms And Types Of Anemia

Anemia Causes, Symptoms And Types

Anemia is a condition in which the blood of a human does not have adequate quantities of red blood cells. The red blood cells have an active component called as haemoglobin, which helps to bind oxygen and helps to transport it successfully to the various organs and tissues of the body. In the absence of haemoglobin, oxygen is not able to reach the various organ systems. Absence of red blood cells and low haemoglobin counts lead to anemia.

Anemia Caused Due to Blood Loss

Anemia of this kind develops gradually and is difficult to detect in its initial stages. For example, scores of menstruating women suffer from anemia. This happens due to the blood loss every month. Moreover, the women rarely compensate for it in the form of a nourishing diet. Certain types of stomach cancers and stomach ailments like gastritis, haemorrhoids and ulcers lead to a slow blood loss. The loss of blood then manifests itself in the form of anemia.

Excessive drug use like the consumption of NSAIDS (Non steroidal and anti-inflammatory drugs) like aspirin and brufen act as blood thinners which leads to a depletion in the red blood cells. This eventually causes anemia. Childbirth and multiple pregnancies can give rise to temporary anemia. However, this normalizes itself after some time.

Anemia Caused by Faulty Red Blood Cell Production

Sickle cell anemia is an inherited disorder that occurs due to the presence of an abnormal gene. In this, the red blood cells are sickle shaped. Because of their shape, they break down rapidly and oxygen does not get to the body’s organs.

Top Causes, Symptoms And Types Of Anemia

Deficiency of certain minerals like iron can also lead to anemia. Iron is an important constituent of haemoglobin, which helps to transport oxygen to the other cells. A deficiency of iron can lead to anemia. In a country like India, women are more prone to getting iron deficiency anemia because of depleted diets that do not contain enough iron.

Certain vitamins are required by the body to help absorb the iron better into the blood stream. Two of the most critical vitamins are folate and Vitamin B12.  Certain diseases like Crohn’s disease cause mal-absorption or absence of these crucial vitamins. Similarly, the deficiency can occur when the intake of fruits, vegetables and meat is too little.

Stem Cell Problems

Stem cell problems where there are too few stem cells, which do not develop into red blood cells can, also lead to anemia.  Some of these stem cells are also replaced by metastatic cancer cells, which then develop into anemia. Exposure to toxic chemicals like benzene and lead can also lead to depletion in the red blood cells.

Hormonal Malfunctioning

Certain types of anemia are caused due to the absence or insufficiency of crucial hormones in the body. Some of the typical conditions are hypothyroidism. This affects the production of the red blood cells.


Symptoms of Anemia

Top Causes, Symptoms And Types Of Anemia

anemia symptoms

While the symptoms of anemia differ from person to person, there are some common symptoms associated with the condition.

Pale Skin

Pale skin and lips are some of the first signs of anemia. The eyes of an individual appear to be yellow. This happens due to lack of haemoglobin in the body. The skin lacks the rosy glow, which is commonly associated with high levels of red blood cells.

Breathlessness and Fatigue

Individuals suffering from anemia are known to tire easily and become breathless. The person may start panting with very mild physical exertion. This occurs due to the lack of oxygen to body tissues.

Dizziness

When the brain detects a fall in the oxygen supply, this manifests itself in the form of vertigo and dizziness especially when the person stands up.

Menstrual Problems

Menstrual problems like absent menstruation or missed periods are common among anaemic women. This occurs due to malnutrition and insufficient iron in their diets.

Slow Wound Healing

Another characteristic symptom of anemia is slow healing and difficulties in recovering. When the red blood cells are not enough, the body’s infection and disease fighting ability is reduced.


Types of Anemia

There are several different kinds of anemia.

Iron deficiency Anemia

Anemia Causes, Symptoms And Types

Iron deficiency anemia

Iron deficiency anemia occurs when the red blood cells are low due to the lack of iron in the body. It is one of the most common forms of anemia and is also easily treated. Iron deficiency anemia is detected through a routine blood test in which the levels of haemoglobin are dangerously low. It can be reversed by taking adequate iron and iron rich foods.

Megaloblastic and Pernicious Anemia

This is a kind of anemia, which is characterized by very large red blood cells. There is some abnormality in their internal development, which causes them to die out much before their 120-day expectancy. The malformation within the cells causes the bone marrow to produce fewer cells.

Haemolytic Anemia

Haemolytic anemia is rare and occurs when the red blood cells in the body are destroyed faster than the bone marrow can make them. This type of anemia can be intrinsic and caused due to defective or faulty genes or it can be extrinsic, caused due to some diseases and environmental factors. Haemolytic anemia can be treated with the help of steroid drug therapy.

Sickle Cell Anemia

Anemia Causes, Symptoms And Types

sickle cell anemia

This anemia occurs when the red blood cells are abnormally shaped and are shaped in the form of a half moon. Because of the defect in the shape, it affects the production of haemoglobin, the compound that helps to transport oxygen to the various tissues and organs of the body. This anemia is aggressive and needs a vigorous treatment approach.

Thalassemia

Thalassemia is an inherited disorder, which occurs when the presence of a defective gene causes a complete breakdown or halts the production of haemoglobin. With no haemoglobin, the patient requires regular blood transfusions on a weekly basis. There is no complete cure for it as it is passed on from the parents to the children.
