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!

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.

Anaemia and How It Can Affect Your Health

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

Did you know that Thalassemia is a common blood disorder in India, that?s passed through families (just the way it was passed to Abhishek Bachchan because megastar Amitabh Bachchan is a carrier). It is characterized by excessive destruction of red blood cells or genetic mutation, leading to anaemia. Today is World Thalassemia Day, lets understand about the disease.

Thalassemia can be classified into alpha and beta, depending on the globin genes that are affected.

1. Thalassemia Minor - Usually doesn?t have any symptoms, except for minor anaemia.

2. Beta Thalassemia - Has two serious types.

2.A) Thalassemia Major: This type usually happens before a child?s second birthday and requires regular blood transfusions. The condition is life-threatening. Symptoms include anaemia, fussiness, frequent infections, paleness of the skin, poor appetite, enlarged organs and jaundice.

2.B) Thalassemia Intermedia: It is a less severe form and doesn?t require blood transfusions. The symptoms include anemia, jaundice, extremely large spleen and malnourishment.

3. Alpha Thalassemia: Only in rare cases this severe form of Thalassemia may be present. Known as Hydrops Fetalis, this condition usually occurs before birth and children are either stillborn or die soon afterwards.

How to live with Thalassemia:

Take steps to be as healthy as possible. Follow a balanced diet eating plan as per the recommendation of your doctor. Take iron supplement only if prescribed. It is recommended that patients get themselves vaccinated whenever needed, especially if their spleen has been removed. Meanwhile, always be on a lookout for the signs of infections (such as fever) and lower your risk of infections. Thalassemia can spark fear, anxiety, depression and stress. That?s why, doctors recommend that patients receive adequate emotional support.

Treatment:

The treatments depend on the kind of Thalassemia an individual has. Usually, treatment procedures include blood transfusions, bone marrow transplants, removal of spleen or gallbladder specific medications and supplements.

What are the Signs and Symptoms of Iron Deficiency Anemia?

Signs and symptoms appear when anemia is moderate to severe. In the mild stage, iron deficiency anemia often goes unnoticed. The signs and symptoms of iron deficiency anemia are:

Extreme fatigue (weakness)
Pale skin and brittle nails
Reduced  appetite
Headache, dizziness, or lightheadedness
Cold hands and feet with tingling numbness
Chest pain, palpitations, or shortness of breath
Inflammation or soreness of the tongue
Unusual cravings for indigestible substances, such as ice, dirt, or starch. 
What are the Causes of Iron Deficiency Anemia? 

Inadequate iron intake: Your body gets iron from the food you eat. If you consume too little iron, then your body may become iron deficient. Hence, resulting in anemia.
Inability to absorb iron: Iron is absorbed into your bloodstream from the food in your small intestine. In conditions like an intestinal disorder, this absorption of iron is hampered which results in iron deficiency anemia. Also, when your small intestine is bypassed or removed surgically, absorption of iron is hampered.
Blood loss: Red blood cells in your blood contain iron, and if the blood loss is severe, you can end up having iron deficiency. Conditions, such as bleeding hemorrhoids, colorectal cancer, and heavy menstruation can result in iron deficiency anemia.
Pregnancy and lactation: During pregnancy and lactation period, the iron requirement of the mother is more, and when it is unfulfilled, she may end up having iron deficiency anemia. 
Which Group is at Risk? 

Vegetarians
Women
Infants and children 
Frequent blood donors
How is it Diagnosed?

Diagnosis is made with the help of: 

Patient s history  
Blood tests, such as CBC and serum ferritin
Some additional tests, such as colonoscopy, endoscopy, and sonography to diagnose the underlying cause
Treatment

Treating the underlying cause is the primary step. 

Severe cases: When the iron level is too low, blood transfusion and even intravenous iron is given
Mild to Moderate Cases: Iron and vitamin C supplements are given in mild and moderate cases of iron deficiency anemia.
Can you Prevent Iron Deficiency Anemia?

Yes. You can prevent iron deficiency anemia by including iron-rich foods in your diet, such as:

Dark green leafy vegetables, such as spinach, peas, and beans
Dry fruits, such as raisins and apricots
Red meat, pork and poultry, and seafoodIron-fortified cereals, bread, and pasta
Include vitamin C-rich foods in your diet to enhance iron absorption. Vitamin C is found in Grapefruit, oranges, strawberries, lemons, and melonsLeafy greens, broccoli, peppers, and tomatoes
