My husband has sleep apnea. He apniated 43 times in one hour in the sleep lab! With a C-PAP machine it came down to 4 per hour. Last night was the first night with the C-PAP. No snoring and the machine is pretty quiet! I would lose weight and do C-PAP before the surgery! There are risks from the surgery and it can become complicated if they have to realign bones! There is probably another cause for your high blood pressure. Get a complete physical and eliminate diabetes and heart disease. Good Luck!
