Understanding high hemoglobin: Causes and risks
Hemoglobin is an iron-rich protein in red blood cells that transports oxygen throughout the body. An above-normal count can be caused by various factors, from lifestyle choices to underlying medical conditions. Smoking is a common culprit, as the body produces more red blood cells to compensate for lower oxygen levels. Living at high altitudes can also naturally increase hemoglobin. Dehydration can lead to a temporarily concentrated blood sample, giving a false reading.
Medical conditions such as chronic obstructive pulmonary disease (COPD), congenital heart disease, sleep apnea, and certain cancers (like kidney or liver cancer) can also elevate hemoglobin levels. The most significant risk comes from polycythemia vera (PV), a rare blood cancer that causes the bone marrow to produce too many red blood cells. Left unmanaged, high hemoglobin can cause the blood to thicken, leading to severe and life-threatening complications.
Lifestyle and dietary strategies to lower hemoglobin
While consulting a healthcare provider is crucial, certain lifestyle and dietary changes can help manage and reduce high hemoglobin levels.
Lifestyle adjustments
- Stay Hydrated: Dehydration can make your blood more concentrated, temporarily raising hemoglobin levels. Drinking plenty of water helps dilute the blood and normalize readings.
- Quit Smoking: Smoking reduces the oxygen available in your blood, which signals your body to produce more red blood cells and, consequently, hemoglobin. Quitting is one of the most effective steps to lower levels.
- Exercise Moderately: Regular, moderate exercise can improve circulation and overall heart and lung health, indirectly supporting healthier red blood cell production. Avoiding extreme endurance training, which can increase red blood cell counts, is also advised.
- Manage Stress: Some studies indicate that severe stress can be associated with increased hemoglobin levels. Regular exercise and stress-reduction techniques can help.
Dietary recommendations
Managing your diet, particularly your iron intake, is key. While many of these foods are healthy, they may need to be limited with high hemoglobin.
- Avoid Iron-Rich Foods: This includes red and organ meats, iron-fortified cereals, and some seafood.
- Limit Iron Absorption Boosters: Foods high in Vitamin C, like citrus fruits, increase iron absorption and should be consumed in moderation or separately from meals.
- Increase Calcium Intake: Dairy products like milk and cheese can inhibit iron absorption.
- Incorporate Water-Rich Foods: Watermelon, oranges, and cucumbers contribute to hydration.
- Avoid Alcohol: Excessive alcohol can impact liver health, and the high purine content in some alcoholic beverages is also a concern.

Medical interventions for reducing hemoglobin
If lifestyle changes are not sufficient or if a serious underlying condition is present, medical treatment may be necessary. Always consult with a healthcare professional to determine the right course of action.
Therapeutic phlebotomy
This is the most common treatment for high hemoglobin, especially in cases of polycythemia vera. The procedure is similar to a blood donation, where a healthcare professional removes a unit of blood from a vein. This reduces blood volume and decreases the red blood cell count. The frequency of phlebotomy depends on the individual's condition and hemoglobin levels.
Medications
For those with polycythemia vera or other chronic conditions causing high hemoglobin, a doctor may prescribe medication:
- Hydroxyurea: This drug is used to reduce the production of red blood cells in the bone marrow.
- Ruxolitinib (Jakafi): This medication is another option, particularly for patients intolerant to hydroxyurea or those with specific genetic mutations.
- Low-dose Aspirin: Taking a low dose of aspirin can help prevent blood clots, a serious risk associated with high hemoglobin.
- Interferon-alfa: This treatment can help slow the production of red blood cells.
Treating the underlying cause
In many cases, elevated hemoglobin is a symptom of another condition. Addressing the root cause is often the most effective treatment. For example, if sleep apnea is the cause, using a continuous positive airway pressure (CPAP) machine can improve oxygenation and help normalize red blood cell production. Treating conditions like heart or lung disease is also critical.
Conclusion
High hemoglobin levels require attention and, in most cases, medical consultation. Simple lifestyle changes like staying hydrated and quitting smoking can be effective, while reducing iron-rich foods in your diet can also make a difference. For persistent or severe cases, therapeutic phlebotomy or medication may be required under a doctor's supervision. By identifying and treating the underlying cause, whether it is a lifestyle factor or a medical condition like polycythemia vera, individuals can effectively manage their hemoglobin levels and reduce their risk of serious health complications. For more in-depth information and personalized guidance, consider consulting a medical professional who can evaluate your specific situation and provide a tailored treatment plan.
