Anemia can come on quickly or gradually, depending on the underlying cause. Symptoms of anemia include feeling tired, weak, short of breath, and pale. If you think you may have anemia, it's important to see your doctor for diagnosis and treatment.
Causes of Quick-Onset Anemia
Anemia can be caused by a number of different factors, including blood loss, a lack of red blood cell production, or an inability of red blood cells to carry oxygen properly. Some of the more common causes of anemia with rapid onset include:
Blood Loss: Blood loss due to injury or surgery can result in anemia very quickly.
Infection: Certain infections, such as malaria, can cause anemia in a matter of days or weeks.
Cancer: Cancers of the blood, such as leukemia and multiple myeloma, can result in anemia very quickly.
Medications: Certain medications, such as those used to treat rheumatoid arthritis, can cause a decrease in red blood cell production, leading to anemia.
Diagnosis and Treatment
If you think you may have anemia, it's important to see your doctor as soon as possible. Your doctor will take a medical history, do a physical exam, and order tests to diagnose the cause of your anemia. Treatment will depend on the underlying cause. For example, if an infection is causing the anemia, treatment may involve antibiotics. If blood loss is the cause, a blood transfusion may be needed. In some cases, iron supplements may be prescribed to help your body produce more red blood cells.
