So I want to help or give you something helpful as before becoming paralyzed I worked in healthcare and public safety but I am a wee bit confused here, under your profile you described yourself as Incont but in your story you mentioned your friends found out about your diaper kink from an ex! There are Incont people that are ab's & dl's just little confused because if you have been diagnosed by a doc with being incont some of the other symptoms could potentially help with a diagnosis or your docs to diagnose you. And your wife joking or asking.you to wear diapers at certain periods of time seem more lifestyle choice vs Medical, which honestly you do you but kind of confused
Also the another part I am super confused with you said by the time the flight attendant came back you were covered in sweat & passed out and was Incont of urine(peed yourself, that in itself could be something that's alarming unless you were under the influence of say alcohol because many people pee themselves and at one time I actually read a medical journal think was UK they had an huge issue with teens and alcohol some local hospital would put nappies on the teens to prevent falls but also because alot peed themselves when intoxicated but even in the US I have seen ER's put diapers on drunk people in the ER because it's noninvasive also some had issues with drunk ripping out Foley's-ouch) if your friend told them your blood sugar was low and she came back and you were altered and or unconscious they would of diverted to the closest airport due to medical on board unless you were evaluated by someone on the plane such as EMT,Doc, Nurse and they felt you were stable they would continue to destination but you would of been greated by fire & ems(in the US police as well as they go to all medicals in the airport) you could of refused care. I would be quite alarmed if your friends and them had to shake you awake and the flight attendants not do anything and as in have seen some call it for intoxicated people that passed out.
Also I take it you aren't diagnosed as diabetic (most diabetics are assigned to an endocrinologist) if you have feeling like you suger is low it could that it could be other things as well. Have you ever had your BGL tested when you were having one of these episodes. You mentioned they told you that your were hypoglycemic was that after bloodwork because hypoglycemic is a clinical term for low blood sugar but if after fasting blood work it could in a different range where it's not really low but for fasting labs it is. But honestly doesn't really matter as it's a number and everyone is different or can act differently it's like low HR or Bradycardia is anything below 60bpm but many athletes live everyday bradycardic! but clinically and could of changed below 60-70 is hypoglycemic usually it's not until someone or something is off that people treat it like I have known diabetics that had full conversations at 35mg/dl and we or they can use Gel tube but at 34 be loopy unable to to protect airway so no gel or juice and anything at/below 34 for that guy we were dropping multiple lines and usually he is taking a ride but had times he awoke a s refused care, but I had another in another she was a poor diabetic in sense she didn't take care of herself so she was routinely clinically Hyperglycemic like 240-60mg/dl but 290 be DKA or in crisis same if she was 200 even though clinical hyperglycemic she acted like she was hypo and was unconscious. So diabetes isn't something to mess with but if your a diabetic, incont and having other symptoms it could potentially lead to something else or like incont can be Neuro related if you have nerve issues depending where on the spine it could cause heart rate to go up or down as well as sweats so like I can't feel anything below the waist but because I have a neurological injury if I don't manage pain well I will sweat but sweating for me is also a warning sign for other things.
I think if you seriously are having to certain symptoms that occur enough times all the symptoms need to present to your doc because it's like there are people who have seizure but they don't always present like TV show seizures and some don't even shake some pass out, some are incont of one or both. But like a cardiac dysrhythmia can cause weird crap. I personally wouldn't diagnosis you as I don't know you and also I no longer maintain my license but what you described sounds like it could be a serious issue
