What is anemia?

Anemia is due to lack of haemoglobin in the blood which is below the normal level or due to less than normal levels of red blood cells in blood.

The haemoglobin helps carry oxygen in blood. Lack of haemoglobin thus causes deficiency of life giving oxygen to vital organs. (1-4)

Types of anemia

There are various causes of anemia. It could be due to:

Decreased production of RBCs in blood
Increased blood loss OR
Excessive destruction of RBCs
Causes of anemia
Anemia most commonly occurs due to nutritional problems. This includes lack of iron in the diet.
Iron deficiency is the commonest form of anemia.
In the United States 7% of toddlers ages 1 to 2 years old and 9-16% of menstruating women suffer from iron deficiency.
The poorer nations 30-70% of the people have iron deficiency anemia.
Iron and anemia

Since iron is needed for the manufacture of haemoglobin in the body its deficiency can lead to anemia.
Iron is found in meat, dried fruit and some vegetables.
Lack of iron may be caused due to bleeding especially in stomach ulcers or within the intestines.
Women before menopause commonly suffer from iron deficiency anemia due to heavy periods and increased demands during pregnancy.
Vitamins and anemia

Certain vitamins like vitamin B12 and folic acid or folate are also essential in the normal production of RBCs in blood. Their lack in diet may lead to anemia.
Both vitamin B12 deficiency and folate deficiency are more common in older people, affecting around 1 in 10 people above the age of 75.
There is an inherited condition called Pernicious anemia where patients find it difficult to use the vitamin B 12 in diet for production of healthy RBCs. This is a rare condition and affects 1 in 10,000 people in northern Europe.
Other causes of anemia

Increased blood loss due to surgery or major trauma may lead to anemia.
Excessive destruction of RBCs may occur due to certain conditions called haemolytic anemias. These are often inherited and include Sickle cell anemia, Thalassemia etc. Anemia can also occur in severe infections, cancers and due to exposure to a drug or toxin.
For example, the RBCs are made in bone marrow. If there is cancer in the marrows a shortage of good red blood cells results. This is called aplastic anaemia and may also occur with blood cancers like leukaemia.
Symptoms

Anemia signs and symptoms vary depending on the cause of your anemia. They may include:

Fatigue
Weakness
Pale or yellowish skin
Irregular heartbeats
Shortness of breath
Dizziness or lightheadedness
Chest pain
Cold hands and feet
Headache
At first anemia can be so mild that it goes unnoticed. But symptoms worsen as anemia worsens.

Treatment of anemia

Treatment depends on the cause of the anaemia. If the anaemia is due to a lack of iron, eating iron-rich food or iron supplements may be given. If, however, the cause of anemia is deeper like internal bleeding or cancers, the cause should be explored before treatment. When the anaemia is more severe, a blood transfusion may be prescribed.

Anemia - Causes, Symptoms & Treatment Of It!

Anemia (or anaemia) is a medical condition which generally occurs in a human body because of the lack of required healthy red blood cells (RBCs) or hemoglobin in the blood. Diagnosis of anemia is done through a blood test, a man is anemic when his hemoglobin level is less than 13.5 gram/100 ml and a woman is anemic when her hemoglobin level is less than 12.0 gram/100 ml.

Risk factors: People suffering from long-term or chronic diseases such as cancer are more susceptible of developing anemia. Hemoglobin is the salient constituent of red blood cells and is an iron rich protein. It provides the red color to the blood and binds oxygen. Red blood cells carry this oxygen to all the vital tissues and organs of the body. Due to lack of appropriate amount of red blood cells, the amount of blood required in a body to function normally is also low. One of the most prominent causes of occurrence of anemia is the deficiency of required amount of nutritional iron, vitamin B-12, and folate in the body. This iron is needed for the formation of hemoglobin. Apart from these causes, the other causes of anemia comprise of the following:

Loss of blood
Insufficient production of red blood cells (inadequate intake of iron, vitamin B-12)
Fast rate of destruction of red blood cells (disorders of liver and hemorrhage)
Diagnosis: It is relatively easy to detect an anemic person. The symptoms of anemia include pale appearance, complaint of cold, giddiness, unsteadiness, laziness, particularly when the person is in action or is standing up. Sometimes people suffering from anemia crave for eating clay, ice, or even dirt. Also, there are complains of exhaustion along with issues of constipation and concentration. Other indications of anemia are brittle nails, gasps for breath even in mild activities, and pain in the chest. Since the level of oxygen in the blood is low, there could be even scope of a heart attack.

A person suffering from anemia is usually diagnosed on the basis of a complete blood count. The blood test brings out if serum folate levels are quite low. In case the anemia is severe, sometimes doctors take the help of erythropoietin injections so as to foster the production of red blood cells in the bone marrow. In case there is bleeding or if the level of hemoglobin is low, it might become essential to carry out blood transfusion.

Treatment: Anemia is straightforward to diagnose and treat, but at the same time could prove to be deadly if it is left undiagnosed. Proper heed should be paid to the intake of adequate and required food which is rich in vitamins and minerals, dietary iron, folic acid, including other vitamins and minerals.

Anemia- How Does It Affect a Person's Health?

Anemia is a medical condition in which the red blood cell count or hemoglobin is less than normal. Haemoglobin is the main part of red blood cells and it binds oxygen. If you have few or abnormal red blood cells, or your hemoglobin is low, the cells in your body will not get enough oxygen. Anemia can last temporarily or for a long-term, and it can range from mild to severe. If you suspect you have anemia, see your doctor immediately because it can be a warning sign of a serious illness. A person who has anemia is called anemic.

Sign and symptoms of anemia: Because a low blood cell count decreases oxygen delivery to every tissue in the body, anemia can cause a variety of signs and symptoms. It can also worsen the state of any other underlying medical condition. If anemia is mild, it may not cause any symptoms. If anemia is chronic, the body may adapt and compensate for the change. In this case, there may not be any symptoms until anemia becomes more severe. Anemia signs and symptoms may vary depending on the cause of the condition. These may include fatigue, weakness, pale or yellowish skin, irregular heartbeats, breathlessness, dizziness, chest pain, cold hands and feet, and headache.

Causes of anemia: Anemia occurs when your body doesn t have enough red blood cells. This can happen if: 

Your body doesn t make enough red blood cells: The bone marrow is essential for the creation of red blood cells. A number of diseases can affect the bone marrow, including leukemia, where too many abnormal white blood cells are produced. This disrupts normal production of red blood cells.
Bleeding causes you to lose red blood cells more quickly than they can be replaced: Iron deficient anemia is the most common type of anemia which often falls into this category. It is caused by a shortage of iron, which most often results due to blood loss. Blood loss can be acute and rapid or chronic. Rapid blood loss can happen at the time of surgery, childbirth, trauma, or a ruptured blood vessel. 
Your body destroys red blood cells: Red blood cells have a lifespan of 120 days in the bloodstream but they can be destroyed or removed beforehand. In one type of anemia, the body s immune system mistakenly identifies its own red blood cells as a foreign substance and attacks them. Excessive red blood cell breakdown can also occur due to infections, the use of certain drugs, snake or spider venom, severe hypertension, and in the case of clotting disorders.
Treatment of anemia: The treatment of anemia varies greatly. First, the underlying cause of anemia needs to be identified and corrected. Most of the times, iron supplements will be needed to correct iron deficiency. In severe anemia, blood transfusions may be necessary. Vitamin B12 injections are necessary in some cases who are suffering from a specific type of anemia.

Prevention of anemia: Many types of anemia can t be prevented. But iron deficient anemia and vitamin deficient anemia can be avoided by having a diet that includes a variety of vitamins and nutrients, including iron, folate, vitamin B12, and vitamin C.

Anemia - What Causes It?

Thalassemia is a genetic (which is passed from parents to children through genes) blood disorder. People with Thalassemia disease are not able to make enough hemoglobin, which causes severe anemia. Hemoglobin is found in red blood cells and carries oxygen to all parts of the body. When there is not enough hemoglobin in the red blood cells, oxygen cannot get to all parts of the body. Organs then become starved for oxygen and are unable to function properly.

Symptoms

The symptoms depend on the type of thalassemia:

Thalassemia Minor: Thalassemia minor usually doesn t cause any symptoms. If it does, it causes minor anemia.
Beta-thalassemia: Beta-thalassemia comes in two serious types, which are thalassemia major, or Cooley s anemia, and thalassemia intermedia. The symptoms of thalassemia major generally appear before a child s second birthday. The severe anemia related to this condition can be life-threatening. Other signs and symptoms include:
fussiness
paleness
frequent infections
a poor appetite
failure to thrive
jaundice, which is a yellowing of the skin or the whites of the eyes
enlarged organs
This form of thalassemia is usually so severe that it requires regular blood transfusions.

Alpha-thalassemia: Alpha-thalassemia also has two serious types, which are hemoglobin H disease and hydrops fetalis. Hemoglobin H disease can cause bone issues. The cheeks, forehead, and jaw may all overgrow. Hemoglobin H disease can cause:
jaundice, which is a yellowing of the skin or the whites of the eyes
an extremely enlarged spleen
malnourishment
Hydrops fetalis is an extremely severe form of thalassemia. It occurs before birth. Most individuals with this condition are either stillborn or die shortly after being born.

Thalassemia - Symptoms Based on Types of Thalassemia 

Anemia is a condition where the red blood cell count is reduced due to deficiencies within the system. This is usually caused by a lack of iron, folate and other related nutrients in the diet. Anemia is a major public health concern in India as over 50 percent of women are known to be anemic. This pushes up the mortality rate of young mothers and even children.

Some symptoms of Iron deficiency anemia
Anemia has a wide range of symptoms which varies from person to person. However there are some generic symptoms which can be noticed in most people. Some of these are
1. Pale appearance of skin - Many people exhibit this symptom where their skin appears to be pale as there is a reduced amount of oxy - hemoglobin in the skin.
2. Physical weakness, light headedness and fatigue - This is a general symptom, which many tend to suffer from and complain about. Fatigue and weakness may come in very quickly even with the slightest effort.
3. Hair loss - Many women may complain about hair loss due to Iron deficiency  anemia.

Some other symptoms are -
a. Breathlessness
b. Constipation
c. Missed or irregular periods
d. Numbness or burning sensations
e. Depression
f. Tinnitus among others

Causes of Iron deficiency anemia
The primary cause of Iron deficiency anemia is the lack of iron in the diet which causes the hemoglobin in the blood to be reduced. Some of the patients may still have Iron deficiencyanemia as they have developed gastrointestinal disorders which prevents the absorption of nutrients like iron within the body.

How to treat Iron deficiency anemia
Diet related anemia can be easily cured or controlled with changing diets. Inclusion of certain foods within the diet can easily reverse the Iron deficiencies. Some of the food items that help with deficiencies are:
1. Fortified cereals
2. Green dark leafy vegetables
3. Poultry items
4. Eggs
5. Meat
You may also require certain iron supplements if you have certain underlying conditions which is causing issues with iron absorption.

How to prevent Iron deficiency anemia
It is important, especially for women to go for regular checkups to your doctor and also a hemoglobin check up. Your doctor or dietician can tell you to include certain foods in your diet that include folate, iron and vitamin B 12 so that the level of hemoglobin in your blood can be maintained at healthy levels.

All About Iron Deficiency - Anemia

The lack of red blood cells or hemoglobin in the blood is termed as anemia. You may also be diagnosed as anemic is your red blood cells do not have a high enough hemoglobin count. Since hemoglobin is responsible for the amount of oxygen in our blood, being anemic results in a decreased flow of oxygen in the blood. 

There are 5 different types of anemia. These are:
1. Iron deficiency anemia: when the iron levels of the blood are lower than normal. 
2. Sickle cell anemia: when the red blood cells are shaped like a'sickle' and hence more fragile. This is an inherited condition. 
3. Thalassemia - when the body does not produce enough red blood cells or hemoglobin. This is also an inherited condition.
4. Megaloblastic anemia - when the blood does not have enough vitamin b12 and hence cannot transport hemoglobin through the body. 
5. Hemolytic anemia - when the red blood cells are rapidly removed from the blood due to an infection, medication or disease. 

Lack of oxygen can have a serious effect on the organs of the body. Hence the symptoms of anemia are also the effects of the disease. 
Some of these are: 
Lack of energy
Fatigue
Dizziness
Chest pain
Difficulty breathing
Abnormal heartbeat
Reduced attention span
Numbness of the hands and feet. 

Anemia can also lead to a number of major health problems such as:
1. Heart disease: anemia is directly linked to heart disease. When the blood carries less oxygen, the heart needs to work harder to pump it to the rest of the body. Thus, people who are anemic are at a higher risk of having a heart attack than a non anemic person. Anemia can also lead to arrhythmia or a condition where the person suffers from an irregular heartbeat. 

2. Pregnancy complications: one of the first and most vital supplements prescribed to a pregnant woman is iron. Iron is essential not only for a healthy baby, but also for your own body. Anemia caused by a lack of iron can result in premature birth and a number of other complications at the time of pregnancy. 

3. Increased risk of infections: lack of oxygen in the blood can affect your immune system by lowering its ability to fight infections. This makes the body vulnerable to diseases. 

4. Cognitive damage: anemia in children can result in a greatly reduced attention span and weaken their memory. Sometimes, even when treated, this can result in permanent scarring and reduced iq levels. 

Fighting anemia is not hard. Consult your doctor instantly if you recognize any of its symptoms and start eating food rich in iron to fight this disease.
