[/INST] Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. After going through your medical query I understand your concern and I would like to tell you that High blood pressure is commonly age related health issue or can be genetics also. Other factors high salt diet, fried and junk food or being over weight are acquired causes of High Blood Pressure. As you mentioned you have OSA that means you can be overwieght (this is what I am guessing that you are overweight as you don't have mentioned here). So, age factor and obesity can be your culprit factors of High Blood Pressure. Kindly start with dietary modifications to low your blood pressure or personally consult your Physician for further management. Hope I have answered your query. Let me know if I can assist you further. </s>
