A very high hemoglobin count can lead to symptoms. Talk with your healthcare professional if you have symptoms such as:
- Trouble with vision.
- Dizziness.
- Headache.
- Slurred speech.
Keep in mind that these symptoms can happen for many different reasons. It's more common to find a high hemoglobin count during a routine blood test or a test checking for another condition. Your healthcare professional likely will do more tests to help figure out the cause of the high hemoglobin count.
