"I'm looking for a connection between weight LOSS and sleep apnea or my CPAP machine. I'm losing a lb a week, thru no changes in diet, exercise, etc, but I think my CPAP is running higher than it used to."
People’s weight responds differently once they start using CPAP regularly to treat their obstructive sleep apnea. Some lose weight, perhaps because the hormones which govern the sensations of hunger satiety (feeling full) are more in balance, resulting in better eating habits. Others gain weight, possibly because they burn off fewer calories now that they have to work less hard at breathing during sleep.
Many people with obstructive sleep apnea see an improvement or even full resolution of their symptoms with weight loss. Therefore, if you’ve lost a significant amount of weight, and feel that your CPAP is now running high, you might need to have its settings adjusted.
One small word of caution: unexplained weight loss can also be a sign of an underlying disease that is totally unrelated to obstructive sleep apnea or CPAP. If you’re not sure what’s going on, please consult your doctor.
