Hi and thanks for the query, management of sleep apnoea required both medical and lifestyle changes depending on the case. I very fat people, loosing weight on its own could be very helpful in reducing sleep apnoea. Other ear. nose and throat conditions could also cause sleep apnoea. Steroid use demands careful medical supervision and monitoring. Its important for your physician to know whether its an idiopathic lip swelling, a reaction form a drug or from another cause. I suggest you visit your primary care physician for a proper medical evaluation and advice. Thanks and best regards, Luchuo, MD.
