I have observed that my mother snores loudly and she feels sleepy during day, she has a medical history of palpitations, high Hp, diabetes etc, I have come across sleep apnea from my other relatives and feel she should also consult as she has also gained weight in last year or so. Please let me know what is the prerequisite for this and is there something we should do before visiting dr Atreja in karnal, I have been asked to call people who test OSA, let me know if that is something which you also ask your patients to do.
