Brief Answer:

Detailed Answer:
Hello and thank you for sending the question.

I am glad the doctors found the source of his bleeding. Since the bleeding is stopped his hemoglobin level will gradually rising overtime. It will probably take several weeks to get back closer to normal.

Glycemic level does not correlate with actual hemoglobin level so checking hemoglobin A1C well actually not be helpful.

The only way to actually monitor the hemoglobin level would be to have a laboratory blood draw to specifically check this level.

As long as he is feeling well and progressively better but hemoglobin level can be monitored periodically with his primary care physician.

Thank you again for sending the question.
