AndBreathe, I haven't checked my weight month by month. I've just hopped on the scales when I've dared because it seems to be running away with me. I'm only 5ft 2lbs so I was way overweight before and that was put down to the underactive thyroid. Yes I'm drinking but not excessively. I'm sure I'm not dehydrated, just exhausted.
OK. So, you have 3 weeks to go before your scheduled appointment, which you can't change. So, it seems to me like you have to make an interim plan for that period. None of what I am going to write is well formed. I'm sort of shooting from the hip, so anybody please feel free to comment or challenge as you see fit.
So, firstly a comment: If you say you have changed nothing from the period you were bringing your bloods into range, you may simply not be eating enough (and if that was the case, you would continue to lose weight). Have you increased your calorie intake along the way to stem the weight loss? Whilst the blood scores you quote (10+) would freak me out too, I can also state categorically that if I don't eat enough my bloods get worse, not better. It seems my body goes into starvation mode and my bloods go up. Could this be happening at all?
So, what would I do?
If I were continuing to lose weight, I would eat more, but clearly trying to avoid increasing the carbs too much a long the way. So, that really means increasing fats. Could you add butter to your veg at mealtimes, or add lashings of butter when you eat bread? Add the odd snack of raspberries with full double cream? Add some cheese regularly? When I wanted to stop losing weight I had to add some cheese to my lunchtime meal, and also a small portion of peanuts. I chose those particular foods as they are high calorie, but and don't add massive amounts to the volume I was consuming. I would also suggest you consciously try adding at least one extra glass of water a day, just to see if that makes a difference. Not being thirsty isn't a sign you are hydrated.
If your bloods continue to be high, I think, bearing in mind it's 3 more weeks, you have two choices. Either accept it, on the basis you will see someone in 3 weeks, or speak with your GP. I can always talk to someone on the same day of calling, if I am unwell (as opposed to wanting to see someone for a routine consultation). If you can talk to your GP, you could ask if he could influence anything with your specialist, as you are feeling so unwell. He may want to see you before he contacts your clinic, but that shouldn't be any hardship?
And thirdly, you could consider asking if there is a community diabetic nurse you could talk to? Even if she doesn't know your whole history, if she is a specialist diabetic nurse, as I understand they usually are, then she should have a view on the best way forward over these few weeks.
But, as sure as eggs are eggs, becoming more and more stressed about things is going to be counter-productive and is likely to add to your feelings of exhaustion.
None of what I say is in any way having a go, or challenging the validity or voracity of what you are doing. I'm just emptying my mind, and sort of overlaying some of the challenges I had myself when I needed to stop losing weight. I lost 3kg after I wanted to stop. I haven't gained it again. For now, I have accepted I run at just under 50kg.
And finally, record everything you eat and drink, along with your bloods and weight. Not weighing yourself isn't helping matters now. You have no way of actually knowing if or what you are losing. When you get to the clinic (whenever that is), you need to have your records with you, as your evidence of what you say. If things are going a bit weird, having the daily documented evidence will help you get the attention you feel you really need.
Keep us in the loop.
