Brief Answer: does not seem to be of concern Detailed Answer: Hi Thanks for your query. This level of hemoglobin is normal for your age. It is a bit on the higher side but ok. The white cell and platelet counts are ok which is good. Does not require further investigations. Do you smoke? Because smoking can also cause this. You don't need to do anything right now. We can monitor the hemoglobin time to time and if it goes above 18 we can do other investigation. Hope I have answered your query. I will be available to answer further followup queries, if any.

Brief Answer: please refer below Detailed Answer: There are several causes like, smoking, high altitude, kidney disease, heart disease, lung disease, sleep apnea, some tumors, etc. Sometimes no cause is found. there is a rare group of disorders called bone marrow proliferative diseases, which can also cause this. Symptoms, usually above 18-20 g/dl, may be easy bruising, easy bleeding, blood clot formation (potentially leading to heart attacks, strokes, blood clots in the lungs), bone and joint pain, headache, itching, itching after taking a shower or bath, fatigue, dizziness, etc. Currently you need only followup. if it is above 18 or there are symptoms,then investigations will be required.
