Anemia arises when your body produces fewer healthy red blood cells than normal, resulting in insufficient oxygen-rich blood circulation. This oxygen deficit can lead to feelings of fatigue or weakness, along with symptoms like breathlessness, dizziness, headaches, or irregular heartbeat. Approximately 3 million individuals in the United States are affected by anemia, according to data from the Centers for Disease Control and Prevention. There are many types of anemia, including:

• Iron-deficiency anemia

• Vitamin B12-deficiency anemia

• Hemolytic anemia

Mild anemia is a prevalent and manageable ailment that can manifest in individuals regardless of age. Its onset can be gradual or sudden, triggered by factors such as dietary habits, medication usage, or underlying medical issues. Anemia can persist over an extended period, constituting a chronic condition that might not completely resolve. Certain forms of anemia are hereditary, with iron-deficiency anemia being the most widespread variant.

Symptoms

If you have mild anemia, you may not have any symptoms. Symptoms of anemia may develop quickly or slowly, depending on the cause of your anemia. General symptoms that are the same for many types of anemia include:

• Weakness

• Paleness

• Tiredness

• Chills

• Shortness of breath

• Headache

• Dizziness and fainting

• Bleeding

Treatment and Management

The treatment for anemia varies based on its underlying cause and severity. Individuals with mild anemia may not require treatment. However, if anemia is induced by medication or another medical condition, your healthcare provider might adjust your treatment regimen to control or alleviate the anemia.

Blood transfusion

A blood transfusion is a common, safe medical procedure in which healthy blood is given to you through an intravenous (IV) line that has been inserted in one of your blood vessels. Blood transfusions replace blood that is lost through surgery or injury, or they provide blood it if your body is not making it properly.

Most of the blood used for transfusions comes from whole blood donations given by volunteer blood donors. A person can also have their own blood collected and stored a few weeks before surgery in case it is needed.
