Anaemia

What Is Anemia?

Anemia is defined as a low number of red blood cells. In a routine blood test, anemia is reported as a low hemoglobin or hematocrit. Hemoglobin is the main protein in your red blood cells. It carries oxygen, and delivers it throughout your body. If you have anemia, your hemoglobin level will be low too. If it is low enough, your tissues or organs may not get enough oxygen. Symptoms of anemia -- like fatigue or shortness of breath -- happen because your organs aren't getting what they need to work the way they should.

Anemia is the most common blood condition in the U.S. It affects almost 6% of the population. Women, young children, and people with long-term diseases are more likely to have anemia. Important things to remember are:

• Certain forms of anemia are passed down through your genes, and infants may have it from birth.
• Women are at risk of iron-deficiency anemia because of blood loss from their periods and higher blood supply demands during pregnancy.
• Older adults have a greater risk of anemia because they are more likely to have kidney disease or other chronic medical conditions.

There are many types of anemia. All have different causes and treatments. Some forms -- like the mild anemia that happens during pregnancy -- aren’t a major concern. But some types of anemia maymay reflect a serious underlying medical condition.click here : Ferox XT Suspension

Anemia Symptoms
The signs of anemia can be so mild that you might not even notice them. At a certain point, as your blood cells decrease, symptoms often develop. Depending on the cause of the anemia, symptoms may include:

• Dizziness, lightheadness, or feeling like you are about to pass out
• Fast or unusual heartbeat
• Headache
• Pain, including in your bones, chest, belly, and joints
• Problems with growth, for children and teens
• Shortness of breath
• Skin that’s pale or yellow
• Cold hands and feet
• Tiredness or weakness

Anemia Types and Causes

There are more than 400 types of anemia, and they’re divided into three groups:

• Anemia caused by blood loss
• Anemia caused by decreased or faulty red blood cell production
• Anemia caused by destruction of red blood cells

Anemia Caused by Blood Loss

You can lose red blood cells through bleeding. This can happen slowly over a long period of time, and you might not notice. Causes can include:

• Gastrointestinal conditions such as ulcers, hemorrhoids, gastritis (inflammation of your stomach), and cancer
• Non-steroidal anti-inflammatory drugs (NSAIDs) such as aspirin or ibuprofen, which can cause ulcers and gastritis
• A woman’s period, especially if you have a heavy menstruation (or heavy period). This can be associated with fibroids.
• Post-trauma or post-surgery as well.

Anemia Caused by Decreased or Faulty Red Blood Cell Production

With this type of anemia, your body may not create enough blood cells, or they may not work the way they should. This can happen because there’s something wrong with your red blood cells or because you don’t have enough minerals and vitamins for your red blood cells to form normally. Conditions associated with these causes of anemia include:

• Bone marrow and stem cell problems
• Iron-deficiency anemia
• Sickle cell anemia
• Vitamin-deficiency anemia, specifically b12 or folate

Bone marrow and stem cell problems may keep your body from producing enough red blood cells. Some of the stem cells in the marrow that’s in the center of your bones will develop into red blood cells. If there aren’t enough stem cells, if they don’t work right, or if they’re replaced by other cells such as cancer cells, you might get anemia. Anemia caused by bone marrow or stem cell problems includes:

• Aplastic anemia happens when you don’t have enough stem cells or have none at all. You might get aplastic anemia because of your genes or because your bone marrow was injured by medications, radiation, chemotherapy, or infection. Other malignancies that commonly effect the bone marrow include multiple myeloma or leukemia. Sometimes, there’s no clear cause of aplastic anemia.
• Lead poisoning. Lead is toxic to your bone marrow, causing you to have fewer red blood cells. Lead poisoning can happen when adults come into contact with lead at work, for example, or if children eat chips of lead paint. You can also get it if your food comes into contact with some types of pottery that aren’t glazed right.
• Thalassemia happens with a problem with hemoglobin formation (4 chains aren't correctly formed). You make really small red blood cells-though you can make enough of them to be asymptomatic, or it can be severe.It’s passed down in your genes and usually affects people of Mediterranean, African, Middle Eastern, and Southeast Asian descent. This condition can range from mild to life-threatening; the most severe form is called Cooley's anemia. click here : Richar CR Syrup

Iron-deficiency anemia happens because you don’t have enough of the mineral iron in your body. Your bone marrow needs iron to make hemoglobin, the part of the red blood cell that takes oxygen to your organs. Iron-deficiency anemia can be caused by:

• A diet without enough iron, especially in infants, children, teens, vegans, and vegetarians
• Certain drugs, foods, and caffeinated drinks
• Digestive conditions such as Crohn's disease, or if you’ve had part of your stomach or small intestine removed
• Donating blood often
• Endurance training
• Pregnancy and breastfeeding using up iron in your body
• Your period
• A common cause is chronic slow bleed, usually from a Gastrointestinal source.

Sickle cell anemia is a disorder that, in the U.S., affects mainly African Americans and Hispanic Americans. Your red blood cells, which are usually round, become crescent-shaped because of a problem in your genes. Anemia results when the red blood cells break down quickly, so oxygen doesn’t get to your organs. The crescent-shaped red blood cells can also get stuck in tiny blood vessels and cause pain.

Vitamin-deficiency anemia can happen when you aren’t getting enough vitamin B12 and folate. You need these two vitamins to make red blood cells. This kind of anemia can be caused by:

• Dietary deficiency: If you eat little or no meat, you might not get enough vitamin B12. If you overcook vegetables or don’t eat enough of them, you might not get enough folate.
• Megaloblastic anemia: When you don’t get enough vitamin B12, folate, or both
• Pernicious anemia: When your body doesn’t absorb enough vitamin B12
• Other causes of vitamin deficiency include medications, alcohol abuse, and intestinal diseases such as tropical sprue.

Anemia associated with other chronic conditions usually occurs in the setting of long-standing inflammation. Inflammatory proteins slow the bone marrow's production of young red blood cells in a variety of ways. Conditions that cause this type of anemia include:

• Advanced kidney disease
• Hypothyroidism
• Old age
• Long-term diseases, such as cancer, infection, lupus, diabetes, and rheumatoid arthritis

Anemia Caused by Destruction of Red Blood Cells

When red blood cells are fragile and can’t handle the stress of traveling through your body, they may burst, causing what’s called hemolytic anemia. You might have this condition at birth, or it could come later. Sometimes, the causes of hemolytic anemia are unclear, but they can include:

• An attack by your immune system, as with lupus. This can happen to anyone, even a baby still in the womb or a newborn. That’s called hemolytic disease of the newborn.
• Conditions that can be passed down through your genes, such as sickle cell anemia, thalassemia, and thrombotic thrombocytopenic purpura (TTP)
• Enlarged spleen. This can, in rare cases, trap red blood cells and destroy them too early.
• Something that puts strain on your body, such as infections, drugs, snake or spider venom, or certain foods
• Toxins from advanced liver or kidney disease
• Vascular grafts, prosthetic heart valves, tumors, severe burns, being around certain chemicals, severe hypertension, and clotting disorders

Anemia Diagnosis
A complete blood count (CBC) test will measure your red blood cells, hemoglobin, and other parts of your blood. Your doctor will ask about your family history and your medical history after the CBC. They’ll probably do some tests, including:

• Blood smear or differential to count your white blood cells, check the shape of your red blood cells, and look for unusual cells
• Reticulocyte count to check for immature red blood cells

Anemia Treatment
Your treatment will depend on your type of anemia. There are lot of causes, so there are also many treatments available.

• If you have aplastic anemia, you might need medication, blood transfusions (in which you get blood from another person), or a bone marrow transplant (in which you get a donor’s stem cells).
• If you have hemolytic anemia, you might need medication that will hold back your immune system. Your primary care doctor may refer you to a doctor who specializes in vascular problems.
• If it’s caused by blood loss, you might have surgery to find and fix the bleeding. If you have iron-deficiency anemia, you’ll probably need to take iron supplements and change your diet.
• Sickle cell anemia treatment includes painkillers, folic acid supplements, intermittent antibiotics or oxygen therapy. A drug. called hydroxyurea (Droxia, Hydrea, Siklos) is often prescribed to decrease sickle cell pain crises (complicated mechanism). The medication called voxelator (Oxbryta) whichcan help your red blood cells keep their proper shape. Crizanlizumab-tmca (Adakveo) can keep the blood cells from sticking together and blocking vessels. L-glutamine oral powder (Endari) can cut down on your trips to the hospital for pain and also guard against a condition called acute chest syndrome.
• If you have a vitamin B12 or folate deficiency, you will be prescribed supplements..
• Thalassemia doesn’t usually need treatment, but if your case is severe, you might have blood transfusions, a bone marrow transplant, or surgery.
