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!

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.

Your body goes through drastic changes when you are pregnant. Your body makes more blood during pregnancy; for instance, prior to pregnancy, your body made approximately 5 litres of blood, but now it produces 7 to 8 litres of it.
Producing excess red blood cells requires haemoglobin, which in turn requires plenty of folate, iron and vitamin B12. If there is a deficiency in any of these requirements, you might develop anaemia.
Anaemia is a condition, which is characterized by a lack of red blood cells in the body. The risks of becoming anaemic during pregnancy include:
1. Being extremely fatigued
2. Miscarriages, premature birth, or low birth-weight
3. The baby can inherit anaemia from the mother
4. The child can have certain developmental delays
5. Postpartum depression (post-childbirth depression)

How it can be prevented?
To prevent such risks, it is important to implement the proper diet. Here are some dietary tips to prevent anaemia during pregnancy: 
1. Consume iron-rich foods: Foods that provide you with the best source of iron are 
i. Poultry and eggs
ii. Dark green and leafy vegetables (for example: spinach, broccoli and kale)
iii. Seeds and nuts
iv. Beans and lentils
v. Tofu
vi. Beetroot
vii. Ripe bananas

2. Don't forget the supplements: Foods are great sources of the nutrients you require, but they may be lacking at times. Ask your doctor for supplements like vitamin, folic acid and iron supplements mostly. Consuming supplements before pregnancy can go a long way in preventing anaemia.

3. Folic acid is important: Folic acid is very important for pregnant women. You must consume 400 milligrams of it to prevent anaemia and birth defects in babies. Foods that are rich in folic acid include:
i. Beans
ii. Muesli
iii. Broccoli
iv. Brussel sprouts
v. Asparagus

4. Vitamins are crucial: Vitamin C helps in iron absorption which boosts haemoglobin production. Some foods rich in vitamin C include
i. Citrus fruits
ii. Strawberries
iii. Kiwis
iv. Tomatoes
v. Bell peppers

5. Be vigilant while cooking: Sometimes while cooking foods, the wrong method can strip them of their iron content. So be careful not to fry, boil or stew such foods too much. Certain foods are best consumed raw; read the labels properly if in doubt.

6. Abstain from certain habits: Alcohol, tea, cigarette and coffee hinder iron absorption. So stop consuming them if you are trying to conceive or have conceived.

Dietary Tips to Prevent Anaemia in Pregnant Women

Iron is an essential nutrient and mineral that is required by adults and children alike. Iron helps move oxygen from the lungs to the rest of the body and helps muscles store and use oxygen. It is especially important for children because it aids development and prevents anaemia. Untreated iron deficiency in children can cause physical and mental delays. It can lead to less healthy red blood cells in the child's blood stream which will cause a delay in the growth of physical and mental faculties.

Risk factors for iron deficiency in children

Infants and children at highest risk of iron deficiency include:

Babies who are born prematurely or have a low birth weight
Babies who drink cow's milk before age 1
Breast-fed babies who aren't given complementary foods containing iron after age 6 months
Babies who drink formula that isn't fortified with iron
Children ages 1 to 5 who drink more than 24 ounces (710 milliliters) of cow's milk, goat's milk or soy milk a day
Children who have certain health conditions, such as chronic infections or restricted diets
Children ages 1 to 5 who have been exposed to lead
Adolescent girls also are at higher risk of iron deficiency because their bodies lose iron during menstruation.
Symptoms of iron deficiency anaemia

The signs and symptoms of iron deficiency anaemia in children may include:

Pale skin
Fatigue or weakness
Slow cognitive and social development
Inflammation of the tongue
Difficulty maintaining body temperature
Increased likelihood of infections
Unusual cravings for non-nutritive substances, such as ice, dirt or pure starch
Prevent iron deficiency in children

Take steps to prevent iron deficiency in your child by paying attention to his or her diet. For example:

Breast-feed or use iron-fortified formula. Breast-feeding until your child is age 1 is recommended. If you don't breast-feed, use iron-fortified infant formula.
Encourage a balanced diet. When you begin serving your baby solids, typically between ages 4 months and 6 months, feed him or her foods with added iron, such as iron-fortified baby cereal. For older children, good sources of iron include red meat, chicken, fish, beans and dark green leafy vegetables. Between ages 1 and 5, don't allow your child to drink more than 24 ounces (710 milliliters) of milk a day.
Enhance absorption. Vitamin C helps promote the absorption of dietary iron. You can help your child absorb iron by offering foods rich in vitamin C, such as melon, strawberries, kiwi, broccoli, tomatoes and potatoes.
Consider iron supplements. If your baby was born prematurely or with a low birth weight or you're breast-feeding a baby older than 4 months and he or she isn't eating two or more servings a day of iron-rich foods, talk to your child's doctor about oral iron supplements.
Make sure that you watch out for the tell tale signs of iron deficiency and take the necessary precautions to avoid the same. If you wish to discuss about any specific child related problem, you can consult a specilized pediatrician and ask a free question.

Iron Deficiency In Children

Iron deficiency is most common among people of all age groups. The nutrient is critical, because it not just produces haemoglobin, it also protects red cells by providing them enough oxygen. Check out these symptoms to know if you are iron deficient.

1) Exhaustion- Do you feel tired, exhausted all the time? Most women think that it?s because of their frantic life. But it could actually be because your tissues don?t get enough oxygen.

2) Heavy Periods- Heavier blood flow is one of the reasons behind iron deficiency. Women may loose too much of blood and might not be able to replace it faster. Periods should only fill two to three tablespoons each month.

3) Paleness- Have people been telling you that you look pale or sickly. Low levels of protein and iron can suck away colour from your skin. 

4) Shortness of Breath- A flight of stairs seem like a mammoth of a task when you have less iron. If you easily get short of breath, it?s time you consult your doctor.

What do we mean by the term Anemia?

It is described as a decrease in the total number of red blood cells, or hemoglobin in the blood, or a decreased oxygen-carrying capacity of blood.

How to know if an individual has Anemia?

An individual with anemia may show one or more of the following signs or symptoms:
Shortness of breath, chest pain, and headache are especially seen with exercise as the oxygen supply decreases
Difficulty in concentration which is mostly seen in children
