Hi
@HarrogateDave . How are you and your good lady this morning? I've a fair idea of how you must feel when your wife goes hypo, my wife is a nurse and she has experienced some quite scary hypos I've had and it has upset her.
Fundamentally a hypo caught early is relatively easy to treat and with a strong positive ally by your side most diabetics should be okay in time. Being prepared for a hypo is essential, know what method of treatment works best, have that treatment to hand at all times and especially for yourself stay calm and positive. ( difficult where loved ones are concerned).
If a hypo progresses to far, all hope isn't lost, but a different treatment may be required. Knowing how to treat a severe hypo may well benefit you and your wife. Failing that, as in your case, be prepared, know how to contact the emergency services, learn how to communicate that your wife is diabetic in the country you're visiting.
Excuse me if I'm wrong but your post suggests that hypos are a common occurrence, if this is true then you maybe fire fighting the problem as opposed to actually stopping the fire in the first place.
Diabetes is about confidence and control. A lot of people on the forum maybe able to help along with DSN and GP services back home.
@catapillar as already given some great advice.
Try to determine the cause of hypos and things should be easier.
Apologies if I'm telling you stuff you already now.
Hope the rest of your holiday is hypo free and totally enjoyable.
