I am sorry that you have been experiencing these episodes during your sleep. It must be frightening for your girlfriend. It is likely that you have sleep apnea and you should follow up with your primary care physician
to discuss your symptoms and possible management.
Obstructive sleep apnea (OSA) is a sleep disorder that involves the pause or decrease in airflow despite persistent breathing effort. This can be associated with excessive daytime sleepiness and other signs of poor sleeping like snoring and restlessness. The prevalence of OSA is about 20% in the general population, so it is a fairly common diagnosis. This usually occurs because of a decrease in airway size while sleeping. So, while your brain is telling your body to take a breath, your airway has partial or complete collapse and does not allow air to pass. Snoring is an attempt your body makes to keep your airway open. There are various different treatments for OSA ranging from machines that give you positive pressure while sleeping to surgery
. Since there can be various components to the cause of OSA, you should follow up with your primary care physician for a full discussion of your symptoms, physical exam specifically looking at your tonsils and airway anatomy, and possible referral to either an ear-nose-throat or sleep specialist
for possible sleep study.
