Anemia is a condition where the body does not have enough healthy red blood cells or hemoglobin to carry oxygen effectively to the body's tissues. Hemoglobin is a protein found in red blood cells that is responsible for transporting oxygen from the lungs to all other organs in the body. Anemia can lead to symptoms like fatigue, weakness, and shortness of breath as reported by Mayor Clinic.
There are many different forms of anemia, each with its own unique cause. Anemia can be a short-term or long-term condition, ranging from mild to severe. It can also be an indicator of an underlying serious illness.
Treatments for anemia may involve taking supplements or undergoing medical procedures. In some cases, eating a healthy diet can help prevent certain types of anemia.
The symptoms of anemia depend on the underlying cause and the severity of the condition. Mild anemia may not cause any noticeable symptoms at first, but as the anemia worsens, symptoms typically appear and worsen as well. If another underlying disease is causing the anemia, the symptoms of that disease may initially mask the anemia. Certain types of anemia have symptoms that point to the specific cause.
Common symptoms of anemia include fatigue, weakness, shortness of breath, pale skin, rapid or irregular heartbeat, chest pain, dizziness, and headaches. If you are experiencing persistent fatigue or shortness of breath without a known cause, it is recommended to make an appointment with your healthcare provider.
Low hemoglobin levels are the primary indicator of anemia. Some people discover they have low hemoglobin when they attempt to donate blood and are deferred due to the low levels.
Anemia occurs when the blood does not have enough hemoglobin or red blood cells. This can happen for several reasons:
- The body is not producing enough red blood cells or hemoglobin
- Red blood cells are being destroyed faster than they can be replaced
- There is blood loss leading to a shortage of red blood cells
Red blood cells contain hemoglobin, an iron-rich protein that gives blood its red color and allows the cells to carry oxygen from the lungs to all parts of the body, as well as carry carbon dioxide back to the lungs. Red blood cells are produced in the bone marrow, which requires iron, vitamin B-12, folate, and other nutrients from the diet to create them.
The main causes of anemia include:
- Iron deficiency anemia - This is the most common type of anemia, caused by too little iron in the body, which is needed to make hemoglobin. Pregnant women, those with heavy menstrual bleeding, and those with internal bleeding are at higher risk.
- Vitamin deficiency anemia - A lack of folate or vitamin B-12 in the diet can prevent the body from producing enough healthy red blood cells.
- Anemia of inflammation - Chronic diseases that cause inflammation, like cancer, HIV/AIDS, rheumatoid arthritis, kidney disease, and Crohn's disease, can impair the body's ability to produce red blood cells.
- Aplastic anemia - A rare, life-threatening condition where the body does not produce enough new blood cells.
- Anemia related to bone marrow disease - Conditions that affect the bone marrow's ability to produce blood cells, like leukemia and myelofibrosis.
- Hemolytic anemias - Red blood cells are destroyed faster than the body can replace them, often due to blood cell diseases.
- Sickle cell anemia - An inherited form of hemolytic anemia where red blood cells become crescent-shaped and die prematurely.
Risk factors for anemia include a poor diet lacking in key nutrients, digestive issues that affect nutrient absorption, heavy menstrual periods, pregnancy, chronic conditions, family history of inherited anemias, infections, use of certain medications, and being over age 65.
Left untreated, anemia can lead to serious complications like severe fatigue, pregnancy problems, heart issues, and even death in severe cases. Preventing iron deficiency and vitamin deficiency anemias through a healthy, balanced diet is important.
Diagnosing anemia typically involves blood tests to measure hemoglobin and hematocrit levels, as well as tests to determine the size and shape of red blood cells. Additional tests may be needed to identify the underlying cause.
Treatment for anemia depends on the specific type. Iron deficiency anemia is usually treated with iron supplements and dietary changes. Vitamin deficiency anemias require supplementation of the missing nutrients. Anemia related to chronic diseases is managed by treating the underlying condition. Other types of anemia may require blood transfusions, bone marrow transplants, or medications.
In general, making an appointment with a healthcare provider is recommended if you are experiencing persistent fatigue, shortness of breath, or other unexplained symptoms that could be related to anemia. Prompt diagnosis and treatment are important to prevent complications.
