What is anemia?

Anemia happens when your body does not have enough healthy red blood cells to carry oxygen where it is needed. Without enough oxygen, you may feel tired, weak, or short of breath during everyday activities.

There are many types of anemia. Some develop from low iron or vitamin levels, while others are linked to medical conditions, blood loss, or inherited disorders such as sickle cell disease.

Anemia can develop for several reasons. Some people lose blood through injury, surgery, heavy menstrual bleeding, or digestive conditions. Others may not get enough iron, vitamin B12, or folate from their diet. Certain chronic illnesses can also affect how the body makes red blood cells.

Some forms of anemia are inherited. Conditions such as sickle cell disease and G6PD deficiency are passed down through families and can affect how red blood cells function.

Symptoms

Anemia symptoms can range from mild to severe depending on the cause and how low the red blood cell count becomes.

Common symptoms may include:

• Ongoing tiredness or low energy
• Weakness
• Pale or yellow-looking skin
• Shortness of breath
• Dizziness or lightheadedness
• Cold hands and feet
• Fast or irregular heartbeat
• Headaches

How is it diagnosed?

Your healthcare provider will begin with a physical exam and questions about your symptoms, medical history, and family history. Blood tests are commonly used to measure red blood cell levels and look for possible causes.

Testing may include a complete blood count (CBC), iron studies, and vitamin level testing. In some cases, additional testing such as bone marrow evaluation or genetic testing may be recommended to better understand the type of anemia.

How is it treated?

Treatment depends on the type of anemia and what is causing it. Many mild cases improve with nutrition changes, iron supplements, or vitamin B12 and folate replacement.

If anemia is linked to another medical condition, treating the underlying problem is also important. Some people may need medications to help the body produce healthy blood cells or prevent red blood cell destruction.

More severe cases may require blood transfusions or specialized treatments. People with inherited or chronic forms of anemia often benefit from long-term care and regular monitoring.

Recovery varies from person to person. Some patients improve within weeks after starting treatment, while others may need ongoing care to manage a lifelong condition.
