Anemia is one of the most misunderstood diagnoses, affecting people of all backgrounds. Misconceptions about anemia can delay diagnosis and treatment. Early diagnosis and proper treatment can restore energy levels and significantly improve overall health.
What is anemia?
Red blood cells contain hemoglobin, an iron-rich protein that binds to oxygen in the lungs and delivers it throughout the body. Anemia occurs when your body does not have enough hemoglobin to carry adequate oxygen to tissues. Without enough oxygen circulating through the body, you may feel tired, weak or short of breath.
When hemoglobin levels are low, organs and tissues also don’t receive the oxygen they need to function properly. Low levels can affect cognitive function, heart health, pregnancy outcomes and overall quality of life. The key is identifying the underlying cause and treating it appropriately.
Surprising facts
It’s not a disease
Anemia is an abnormal lab finding that is a result of a greater issue, such as iron deficiency, a chronic disease, internal bleeding or a genetic disorder like Sickle Cell Disease. If you have anemia, the most important question is why?
You may not feel tired
Fatigue is common, but not everyone with anemia feels exhausted. Mild anemia can quietly affect concentration and mood before obvious physical symptoms appear. Some people only notice:
- Craving for ice
- Irritability
- Hair thinning
- Brittle nails
- Feeling cold all the time
Iron supplements aren’t always the answer
People often assume anemia equals low iron. But that’s not always true. Anemia can also be caused by low vitamin B12, folate deficiency, kidney or liver disease, autoimmune conditions or bone marrow problems. Taking iron when you don’t need it can cause:
- Constipation
- Nausea
- Stomach pain
- Iron overload (in rare cases)
Heavy periods are a major cause
Many women normalize heavy menstrual bleeding and don’t realize it can lead to chronic iron deficiency anemia. Discuss with your provider if you soak through protection every 1-2 hours, pass large clots or feel exhausted during or after a period.
Anemia can affect the heart
When oxygen levels are low, the heart works harder to compensate. Over time, untreated anemia can contribute to a rapid heartbeat, shortness of breath or a worsening heart condition. It can also negatively impact major organs.
Symptoms can mimic other conditions
Especially in older adults, anemia may be mistaken for part of the aging process and can result in falls, confusion, decreased independence and depression-like symptoms.
Diet alone can fix anemia
Even with a healthy diet, some people are unable to fully absorb iron due to other factors, including digestive conditions affecting nutrient absorption or ongoing blood loss.
It’s extremely common, especially in women
Globally, anemia affects a significant percentage of women of reproductive age. It’s often underdiagnosed because symptoms develop slowly and become normal to the person experiencing them.
The bottom line
A simple blood test, often called a complete blood count (CBC), can diagnose anemia. Treatment depends on the underlying cause but could include:
- Iron, vitamin B12 or folate supplements
- Dietary changes to include iron-rich foods, such as lean meats, beans, leafy greens and fortified cereals
- Medications to stimulate red blood cell production
- Treatment for an underlying condition
- In severe cases, blood transfusions
If you are experiencing symptoms of anemia, talk with your healthcare provider or schedule a visit with one of our primary care providers.
