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

World Sickle Cell Day is observed each year on June 19th to raise the public awareness regarding this disease and its treatment methods. Sickle Cell disease is an inherited transmitted deformity/abnormality of haemoglobin. It is an inherited form of anaemia. This abnormality generates changes in the shape of red blood cells from round to crescent, which reduces the oxygen carrying capacity and slows down the flow of blood to various parts of the body. 

Generally, red blood vessels are round and flexible, passing easily through the blood vessels. The red blood cells become sticky and rigid in sickle cell anaemia. Sickle cells last 10 to 20 days, which causes anaemia because of the disorder of red blood cells, while healthy red blood cells could live up to 120 days.

Millions of people around the world are affected by Sickle Cell Anemia. There is no specific cure for this disease as Sickle cell anaemia is not contagious, it is hereditary. Sickle cell anaemia is named so for the reason that red blood cells are crescent-shaped or sickle-shaped, and anaemia signifies lack of blood. There is a difference between iron-deficiency anaemia and sickle cell anaemia.

Symptoms

Sickle Cell Disease (SCD) has many symptoms which includes: serious anemia, episodes of suffering, additionally a range of complications, heart failure, dizziness, chronic kidney disease (CKD), acute chest syndrome (ACS), chest pain, gallstones, pulmonary hypertension, immune deficiency, paralysis or stroke, splenomegaly, joint damage mainly in the hip joint, foot ulcers, delayed puberty, retinopathy, and endocrine disorders.

Diagnosis

Sickle Cell Disease is diagnosed by blood tests.

Treatment

Bone marrow transplant or stem cell transplant in patients usually below the age of sixteen is the only available cure for the disease.

Aim of the World Sickle Cell Day

The aim of the World Sickle Cell Day is to support and promote research for the patients in order to help them upgrade their overall quality of life to the maximum possible extent. It also aspires to increase awareness for sickle cell disease disorder in the general public so that they know how to deal with patients suffering from the disease. Moreover, the World Sickle Cell Day has the objective of raising awareness of the importance among generations of pre-marital screening to lessen the transmission of Sickle Cell Disease.

Target Groups for Awareness Programs

Though it is desirable that everybody knows about Sickle Cell Disease, the target groups for the awareness programs include health decision-makers, sickle cell anaemia sufferers and their families, health organizations and associations, people who are planning to get married, and the health workers including health educators, physicians, and nurses.

On the World Sickle Cell Day, different societies provide advocacy, information, and advice for raising awareness. They also provide educational and welfare grants, support services, annual children s holiday, home help, hospital visits, mentoring and befriending through holding talks, assisting into research and training, lobbying for better service provision, patient education seminars, and campaigning.

World Sickle Cell Day - What Should You Know?

Anemia refers to a condition wherein the body possesses fewer red blood cells than what it contains under normal circumstances. Oxygen gets carried by the red blood cells to tissues and organs all over the body, thereby enabling them to use the necessary energy from food. A person suffering from anemia, will have his red blood cells carrying less amount of oxygen to organs like heart and brain, thus interrupt smooth functioning of the organs. Kidney disease leads to the problem of anemia. In fact, it is a very common side effect of kidney disease, wherein the body fails to produce the required amount of red blood cells.

What results in anemia?
A person can suffer from the problem of Anemia, when sufficient amount of red blood cells are not there in the body. Oxygen is carried through a person s bloodstream by the Red blood cells, providing him energy and also ensure that the bones, muscles and organs function properly. Anemia can make a person feel weak and very tired as he or she is unable to receive the required amount of energy.

How can chronic kidney disease lead to anemia?
Anemia is common among people, who suffer from chronic kidney disease, though the problem can occur to anyone. People suffering from chronic kidney disease may have anemia during the early stages of their kidney disease and as the kidney problem gets worse, so does anemia. Improper functioning of kidneys generally link towards the problem of anemia. People, who suffer from complete loss of kidney function, tend to develop the problem of anemia. Kidney failure leads to a person, requiring dialysis or kidney transplant, for ensuring longevity.

Anemia becomes even more common in chronic kidney disease, if a person:

Has high diabetes.
Is suffering from heart problems.
Has a high level of blood pressure.
Some of the other causes of anemia in people, suffering from kidney disease include loss of blood from hemodialysis and lower levels of some of the nutrients like iron, folic acid and vitamin B12, found in food.
These three nutrients are essential for the red blood cells to make haemoglobin, which is the main carrier of protein through oxygen in red blood cells.

Signs and symptoms of anemia with chronic kidney disease
The signs and symptoms of anemia in someone, suffering from chronic kidney disease are:

He might have terrible weakness.
A person might suffer from headaches on a frequent basis.
There would be problems with regard to concentration.
The color of the skin would become pale.
Treatment
A doctor would try and increase the levels of iron in a person s body, as the first step of treatment. Iron pills would help in improving the levels of iron and haemoglobin. Red Blood Cell transfusion is another way to treat this problem. Transfusion would be done inside the patient s vein by raising the level of the patient s blood consisting of red blood cells, thereby also increasing the amount of oxygen. Vitamin B12 and Folic Acid supplements are also suggested by healthcare providers, to help treat anemia.

Anemia - How Chronic Kidney Disease Can Lead To It?

Iron deficiency anemia is a type of anemia, which occurs due to deficiency of iron. Iron is the main component of hemoglobin. So, a decrease in the hemoglobin level results in iron deficiency anemia.

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

Iron Deficiency - What Are The Possible Signs And Symptoms?

Anemia is a disease which occurs due to the lack of red blood cells or hemoglobin in your body. The body transports oxygen and the nutrition you get from food, to various body parts through hemoglobin, and a deficiency can cause lower supply of these important elements to the body. Which is why, the patient may feel a lack of energy, dizziness and even exhaustion. Most people don't realize its existence, so it's important that you know the symptoms, causes and cures of this blood disease. And, the foods one should eat to avoid anemia.

Lack of iron: There are various forms of this illness, and one of it is iron deficiency anemia. The red blood cells in the blood contain hemoglobin, which requires iron for formation. If the diet is not adequately loaded with iron, the person can have iron deficiency anemia. This is the most ordinary one that occurs to people, but with adequate care through food, exercise, and medicines, you can tackle it.
The root cause: Faulty production of red cells (hereditary conditions like sickle cell anemia, bone marrow disorders, etc. is the common cause of anemia. Excessive destruction of red blood cells, which is not compensated by normal production (spleen disorders, thalassemia, etc.) can be another reason. People with blood loss conditions (ulcers, gastritis, internal bleeding, excessive menstruation, childbirth, etc. and the ones who consume a poor diet can also get this blood disease.
Know the symptoms: There are essentially nonspecific symptoms of anemia, but overall fatigue with very low energy levels as the body does not receive enough nutrition to perform various functions can be one of them. Reduced heart rate, fainting, and pallor of skin and whites of the eye are common indicators of this illness. Check with your doctor if you face any of these issues.
Foods for prevention: If you follow a healthy diet that is full of nutrients like iron, you can keep anemia at bay. Remember, weight is not an issue here. If you have a good diet intake, you need not worry about being slim. Often, women who are thin get labeled as anemic, which is far from truth. When it comes to nutrients, iron-rich foods should be eaten along with vitamin C to improve its absorption. Vitamin B12 also plays a significant role in absorption. Meat including red meat, lamb, pork, chicken, beet, ham, turkey, and seafood including salmon or tuna can be included in your diet. Other foods like legumes, soybeans, veggies (dark green leafy vegetables, spinach, peas, broccoli), dried fruits and nuts, tofu, pumpkin and eggs are rich sources of iron that can be consumed by vegetarians. Cereals like red rice, brown rice or fortified cereals with a good source of iron can also be included in the diet.
Don't miss out on iron, ladies! Women are likely to be anemic (with symptoms like fatigue and paleness) and hence they should constantly monitor for iron levels and shift to a diet rich in iron. Furthermore, iron supplements can be consumed in the form of tablets, syrup, or tablets with the guidance of a doctor. In severe cases, where there is a significant blood loss, especially with childbirth or internal bleeding, the sufferer may require transfusion. All in all, anemia is definitely manageable with planning of diet, especially during times the like menstruation and pregnancy. So, taking care on time is a vital step.
