Anemia is a condition in which the blood does not have enough healthy red blood cells or enough hemoglobin, the protein that carries oxygen through the body. When oxygen delivery drops, you can feel tired, weak, cold, dizzy, or short of breath. Iron deficiency is the most common cause, and anemia can also stem from blood loss, vitamin deficiencies, chronic disease, or inherited conditions. Avita MD primary care providers diagnose and treat anemia for adults in Los Altos, Mountain View, and Los Gatos, finding the cause and matching treatment to it.
What are the symptoms of anemia?
Mild anemia may cause no symptoms at all. As it progresses, the most common signs reflect the body working harder to move oxygen:
- Fatigue and weakness
- Pale skin
- Shortness of breath
- Dizziness or lightheadedness
- Cold hands and feet
- Headache or trouble concentrating
Because these symptoms are easy to dismiss as everyday tiredness, a simple blood test is the way to know for sure.
How does Avita MD diagnose and treat anemia?
At Avita MD, diagnosis starts with a complete blood count to confirm anemia, often followed by iron studies and vitamin levels to find the cause. Our on-site phlebotomy means blood can be drawn during your visit instead of at a separate lab, and same-day and next-day appointments let us act quickly when you feel unwell. We review your results with you and look for the source, whether that is low iron, a vitamin deficiency, blood loss, or a chronic condition.
Treatment depends on the cause. Iron-deficiency anemia is often treated with dietary changes and iron supplements, while B12 or folate deficiency is treated by replacing those vitamins. The table below lists everyday iron-rich foods:
| Food group | Iron-rich examples |
|---|---|
| Animal sources | Lean red meat, salmon, eggs |
| Plant proteins | Beans, peas, tofu |
| Vegetables | Dark green leafy vegetables |
| Fortified foods | Iron-fortified breads and cereals |
| Fruits | Dried fruits such as raisins and apricots |
When anemia points to blood loss or a more complex cause, Avita MD coordinates referrals to gastroenterology, hematology, or women’s health and follows up to confirm your levels recover. We track hemoglobin over time through longitudinal records so we can confirm treatment is working and catch any recurrence.
When should you see a doctor about anemia?
Make an appointment if you have ongoing fatigue, pale skin, shortness of breath with normal activity, dizziness, or an unusually fast heartbeat. Anemia found on a routine blood test also deserves a follow-up to find the cause. Seek urgent or emergency care for chest pain, severe shortness of breath, fainting, or signs of significant bleeding such as black or bloody stools alongside weakness. Because anemia can be the first clue to another condition, getting evaluated protects both your energy and your overall health.

Anemia: Frequently Asked Questions
What causes anemia?
The most common cause is iron deficiency, since the body needs iron to make hemoglobin. Anemia can also result from blood loss, vitamin B12 or folate deficiency, chronic disease, or inherited conditions such as sickle cell disease or thalassemia.
How is anemia diagnosed?
Anemia is diagnosed with a blood test called a complete blood count, which measures hemoglobin and red blood cells. Your provider may add iron studies, vitamin levels, and other tests to find the cause. Avita MD offers on-site phlebotomy so blood can be drawn at your visit.
Can diet treat anemia?
Iron-rich foods such as lean red meat, beans, eggs, tofu, dark leafy greens, and iron-fortified cereals support red blood cell production. Diet alone may not correct a significant deficiency, so your provider may also recommend supplements and will treat any underlying cause.
Is anemia serious?
Mild anemia is often easily treated, and severe or untreated anemia can strain the heart and signal a serious underlying problem. Because anemia can be a sign of another condition, it should always be evaluated by a provider.
When should I worry about anemia symptoms?
Seek prompt care for chest pain, a rapid or irregular heartbeat, severe shortness of breath, or fainting, as these can mean the anemia is severe. Black or bloody stools with fatigue also need urgent evaluation.
