It is when you have low levels of healthy red blood cells to carry oxygen throughout your body. Symptoms include fatigue, weakness and feeling short of breath. They can be mild or severe. it may be life-threatening. Many things may cause it and there are different types of the condition. Treatment varies depending on why you have it. It is a blood disorder that happens when you don’t have enough red blood cells or your red blood cells don’t work as they should. Some types of anemia are inherited, but people may also acquire or develop the condition during their lifetimes.
Anemia can affect your life in different ways. Some types of this condition have mild symptoms that ease with treatment. Other types are more serious, like some that people inherit that cause lifelong medical issues. Severe it can be life-threatening. This condition may also be a symptom of serious conditions like cancer.
Is anemia a common disease?
Yes, it is. Experts estimate that 3 million people in the U.S. have it. They also estimate the condition affects 1 in 3 people in the global population.
Symptoms and Causes of Anemia
What are the symptoms?
Fatigue — feeling too tired to manage your activities — is the most noticeable symptom. Other symptoms may include:
Chest pain.
Dizziness.
Frequent infections.
Heart palpitations.
Headache.
Pallor (skin color that’s paler than usual).
Pulsatile tinnitus.
Shortness of breath (dyspnea).
What causes it?
Many things can cause it. For example, iron-deficiency anemia is the most common type of anemia. You can develop this type if you don’t get enough iron from the food you eat, or if you lose blood from an injury or illness. Healthcare providers classify it as being acquired or inherited.
Acquired anemia
You develop or acquire anemia from something that happens during your lifetime, like a condition that causes it. Acquired anemias include:
Anemia of chronic disease: You can develop this condition if you have an illness that causes chronic inflammation, making it hard for your body to use the iron it needs to make red blood cells.
Autoimmune hemolytic anemia: In this case, your immune system attacks your red blood cells.
Macrocytic anemia and megaloblastic anemia: These are types of ane-mia that develop when your bone marrow makes unusually large red blood cells. Certain medical conditions and vitamin deficiencies may cause these types of anemia. Healthcare providers may call these conditions vitamin deficiency ane-mia.
Normocytic anemia: In this type, you have fewer red blood cells than usual. There are many causes of normocytic anemia.
Pernicious an-emia: This condition, which is one of the causes of vitamin B12 deficiency, is an autoimmune condition that prevents your body from absorbing vitamin B12.
You can also develop an-emia if you have certain chronic diseases.
Anemia may be a symptom or complication of the following:
Autoimmune diseases.
Cancer.
Inflammatory bowel disease (IBD).
Kidney disease.
Liver disease.
Thyroid disease.
Inherited ane-mias
An inherited an-emia is when you’re born with the condition. Inherited anem-ias include:
Diamond-Blackfan anemia: This inherited disorder keeps your bone marrow from making enough red blood cells.
Fanconi anemia: This is a rare blood disorder. People with Fanconi anem-ia have an increased risk of blood disorders, including anemia.
Sickle cell anemia: This condition changes your red blood cells’ shape, turning round, flexible discs into stiff and sticky sickle cells that block blood flow.
Thalassemia: In this condition, your body produces less hemoglobin, resulting in small red blood cells and anemi-a.
Other anemia types
Some types of anemia may be inherited but can also be acquired:
Aplastic anemia: This anemia happens when stem cells in your bone marrow don’t make enough blood cells.
Hemolytic anemia: In this anemia, your red blood cells break down or die faster than usual.
Microcytic anemia: This anemia happens when your red blood cells don’t have enough hemoglobin so they’re smaller than usual. Microcytic anemia occurs with iron deficiency, thalassemia, and sideroblastic anemia. It also occurs in some people who have it of chronic disease.
Sideroblastic anemia: Sideroblastic anemia results from abnormal iron use during red blood cell development.
Diagnosis and Tests
How is ane-mia diagnosed?
Your healthcare provider will ask questions about your symptoms. As it happens when you don’t have enough healthy red blood cells, they’ll do blood tests, including:
Complete blood count (CBC): Healthcare providers use this test to check on all of your blood cells, with a focus on your red blood cells. Medical pathologists examine blood samples to count your red blood cells. They also examine your red blood cells’ size and shape. Healthcare providers may use this test to check on your vitamin B12 or B9 levels.
Hemoglobin test: Hemoglobin is the main component of red blood cells. The test is often used to detect it.
Hematocrit test: This test measures the percentage of red blood cells in your blood.
Peripheral blood smear: Healthcare providers examine your red blood cells under a microscope to assess blood cell size and shape.
Reticulocyte count: Reticulocytes are immature red blood cells. This test checks if your bone marrow is producing enough healthy red blood cells.
What are the complications of it?
Chronic anemia can cause serious medical issues like heart attack, heart failure and organ damage. Chronic anem-ia is it that healthcare providers don’t diagnose and treat or that continues despite treatment.
Management and Treatment
How is ane-mia treated?
Your treatment will vary depending on the cause. If you have it because you have an underlying condition, your provider will treat that condition. But they may also do the following treatments specifically for it. Treatments may include dietary supplements or medications.
Dietary supplements
Your provider may recommend the following supplements for ane-mia:
Iron supplements: This supplement comes in capsules or tablets that you can take by mouth with a glass of water.
Folic acid supplements: Vitamin B9 (folate) is an essential vitamin that helps your body form red blood cells and DNA, which are the building blocks of your body.
Vitamin B12 supplements: Vitamin B12 supplements support the production of healthy red blood cells.
Medications
Providers may prescribe medications for it, including:
Erythropoietin: This medication helps your bone marrow to produce more blood stem cells.
Immunosuppressants: If you have it because of an autoimmune disorder, your provider may prescribe medication that keeps your immune system from attacking your red blood cells.
Procedures
In some cases, your provider may recommend:
Blood transfusion to replace red blood cells.
Stem cell (bone marrow) transplant to replace unhealthy blood stem cells with healthy ones.
Surgery to treat internal bleeding that’s causing it.
Can I fix it by myself?
Most of the time, an-emia causes mild symptoms and is a short-term issue that you may be able to manage by changing your diet or taking supplements once a healthcare provider concludes that it is the reason why you have certain symptoms.
But it may cause symptoms of other diseases. For example, something other than it may be why you feel exhausted no matter how much rest you get.
Talk to your healthcare provider if you have fatigue or other changes in your body that don’t go away within two weeks. They’ll find out what’s causing your symptoms and treat the condition.
Prevention
Can it be prevented?
You may be able to prevent the most common type of anemia, iron-deficiency anemia, by including iron-rich foods in your everyday meals and snacks. But there are other types of it you can’t prevent, including inherited disorders.
Outlook / Prognosis
Can you live a normal life with it?
That depends on your situation. Treatment may manage it symptoms. But many things can cause it, like incurable inherited disorders and chronic diseases. Chronic anemia, like it that goes without treatment, can cause serious complications, including organ damage. If you have it, ask your healthcare provider what you can expect.
Living With
How do I take care of myself?
While some types of anemia are short-term and mild, others can last a lifetime. Regardless, there are several things you can do to help manage symptoms. Here are some suggestions:
Follow a healthy eating plan: Poor eating habits are the primary reason why people develop it. Ask your healthcare provider about iron-rich foods and other foods you should eat to meet your body’s nutritional needs.
Take your supplements as directed.
Drink up: Drink lots of water so you stay hydrated.
Keep moving: Regular exercise is part of a healthy lifestyle. But be sure to check with your healthcare provider about ways to exercise safely.
Protect against infection: Wash your hands often. Ask your provider about vaccinations that help prevent viral and bacterial infections.
When should I seek medical care?
If you have it, you should check with your provider if your symptoms get worse despite treatment or if you notice changes in your body that may be new symptoms.
When should I go to the emergency room?
It may increase your risk of a heart attack. Call 911 if you have the following symptoms:
Chest pain.
Shortness of breath or trouble breathing.
Fatigue.
Trouble sleeping (insomnia).
Nausea or stomach discomfort. Heart attacks can often be mistaken for indigestion or heartburn.
Heart palpitations.
Anxiety or a feeling of “impending doom.”
Sweating.
Feeling lightheaded, dizzy or passing out.
