Hi and welcome.
Sorry to dear your chap is struggling with his diabetes management..... particularly nocturnal hypos.... but great that you want to learn so that you can better support him. Also great that he has Dexcom although it sounds like he is self funding which is a bit financial outlay
😱 but worth it for peace of mind if you can afford it. From what I have read he may find the Libre a bit of a second class alternative, but as someone who has only ever had Libre, I absolutely love it. I don't think it has the facility to link to other mobiles though like Dexcom does.
You seem to realise that it can be a bit of a tetchy situation offering support without being intrusive. Unfortunately the nature of hypos can sometimes mean that we can become difficult and resistant as our brains get a bit short on glucose. It sounds like you have a pretty good approach to it from what you describe. I believe
@everydayupsanddowns has an etiquette protocol for managing such situations which might be useful to you so hopefully he will be along when next online to post a link to it.
I am sure we are more than happy to fill you in with any information and support we can, but would your partner consider joining the forum too. It can really be helpful to compare notes with other diabetics as we can learn so much more from each others' practical experiences. Just the fact that we understand the frustrations and challenges it brings on an daily basis and share them with each other can ease some of the mental strain of it all, but we can also offer suggestions and practical tips for fixing particular management problems..... or suggest what to try or check in order to try to improve things. For instance nocturnal hypos would suggest a basal (long acting insulin) check would be appropriate assuming they happen after his bolus (meal time) insulin has finished working. Sometimes a change of dose is all that is needed, other times a change of basal insulin to one with a different profile might suit him better. Sometimes just the timing of when he takes it can fix things, so lots of options and suggestions if we have more info about specific problems.
Anyway, I am so pleased to hear that you are already finding reading other posts helpful and if there are any specific issues or questions that you have, feel free to ask them. Do remember that the forum is a mixture of members with different types of diabetes and some information is more relevant to Type 2 than Type 1 say, so keep an eye out for Type 1 members which shows in the username box at the left of the post, as that will hopefully provide you with more appropriate information to your partner's situation.
