Hello,
A hemoglobin level of 18 g/dL is considered high and can be linked to conditions such as polycythemia, dehydration, lung diseases, heart conditions, or even living at high altitudes. Your symptoms of lightheadedness may be related to increased blood viscosity, which can lead to poor circulation, dizziness, headaches, and a higher risk of blood clots.
Possible Causes of High Hemoglobin:
1. Dehydration – Reduced plasma volume can falsely elevate hemoglobin levels.
2. Lung Diseases (COPD, Sleep Apnea) – Chronic low oxygen levels can stimulate excess RBC production.
3. Heart Disease – Congenital heart defects or other issues may contribute.
4. Polycythemia Vera (a bone marrow disorder) – This condition causes excessive RBC production and requires medical attention.
5. Excessive Smoking or Anabolic Steroid Use – These can lead to high hemoglobin levels.
What You Can Do:
Stay Well Hydrated – Dehydration can falsely raise hemoglobin levels.
Avoid Smoking & Alcohol – These can contribute to elevated RBC production.
Monitor Oxygen Levels – If you experience breathlessness, check for any underlying lung issues.
Regular Exercise – Helps maintain circulation and prevent blood thickening.
Medical Evaluation – Further tests like JAK2 mutation analysis may be needed to rule out polycythemia vera.
Since high hemoglobin levels can have serious implications, I strongly recommend an immediate consultation to assess your case and prevent complications.
