Extremely High After Being Low

The last two evenings I have been low just prior to having my evening meal.

Monday evening I was 3.4 which I treated in the normal way. Last night I was 4.1 so just went on and had my evening meal as normal and had my insulin after my meal. Last night I did go on to feel like I was hypo when I was eating. I didn't treat it but maybe I should have stopped my meal to treat it.

At bedtime after these incidents I have gone very high and was wondering if anybody else ever has this? I've never seen huge rebounds after hypos but the last two nights have bounced really high.

Monday night I was 16.6 before bed and 15.6 the next morning on waking. Made sure I had no ketones as well and kept hydrated.

Last night I was 18.3 and again luckily had no ketones. I took a bit of a correction last night as I didn't want to be too high again this morning. When I got up this morning I was 6.9 which I was happy with.

Just wondered if anyone else had seen this happening?
 
Yes - more vividly on cgm - no expert, just my experiences but the pattern I tend to see in me is that if I have a low where I drop really quite low even just briefly (so treating the hypos the minute you notice is important with cgm I can start treating before they happen as I can see a downward trend and what my sugar level is) or one of those persistent lows that you eat, then eat again, then eat again - I can have rebounds. Bizarrely they don't necessarily happen right at the time, but can start an hour or so later - so ironically less hypos means less rebounds and less high sugars :D I'd just try and adjust your doses to get rid of the hypos and then hopefully you'll be fine. But completely normal in my book. Also someone I was talking to about hypos was saying that Drs are looking into whether hypos in the previous day can lead to dawn phenomenon where you sugar rises in the morning - but I haven't seen anything conclusive on this at all I think it is all research.

I saw someone post that you shouldn't treat the rebounds with insulin - though I always have, so if anyone knows why you shouldn't then let me know…I have to say that if it is a rebound then I do always tend to be more conservative with my insulin mainly because I don't want to go hypo again so I wouldn't give as much as if it was a high from eating to much food or something like that.

Hope that helps :)

Hi

It looks as though a pattern is starting here where youve had the same bg levels for 2 days in a row.

Sometimes insulin does this type of thing even though we try our best to get carb ratios correct and the basal ok.

This is what I would do...........If you are going low just before your eve meal, then the easiest way to way lay the hypo feeling is to eat about 2 jellybabies about 30-45mins before the low feeling starts or drink a small amount of lucozade or have some glucose tabs. That will halt the hypo feeling...... If you dont already do it, do a bg test about 2.5hrs after your lunch meal just to see if the bg level has changed to what you thought it should be. Obviously, if your bg level has changed, then you can eat a small snack or alter the lunch carb ratio. The choice is yours :)

Where the high is coming later in the evening, the way to deal with that is probably by altering the evening meal carb ratio so that more insulin is delivered and then by trial and error with the adjusting, you'll be able to go to bed with bg levels that are ok again.

Hope this helps you
 
Thanks for your replies.

Another reason for some of last nights high was I had homemade falafel last night and went by the reading for the chickpeas from the tin. I think I might have misinterpretted it as when I looked them up in carbs and cals the value is much higher. I may have been confused by the weights at the time.

I'll keep an eye on it this evening, although I always end up being a bit lower later on a Wednesday as I am much more active.
 
Maybe try to test an 1/2 hour or so before you have been having the hypos and see if you can catch it with a small snack. I hadn't thought about you might just be a post food rise too - but I guess if you can eliminate the hypo then you will know whether it was the hypo or just a change in your insulin requirements. (there are just so many things to take into consideration - I guess the only other one being making sure you don't over treat the hypo which could also give you highs too) Good luck I hope you get to the bottom of it :)

My doctors have always told me that if you have a hypo, you're more prone to them for the rest of the day, but they don't know why. Is this familiar to anyone, and does anyone have any thoughts on it?

I've always been told this by the nurses at the hospital as well. Very rarely had it happen but they've always mentioned it.

I've had a hypo every Wednesday evening this year due to having Cub Scouts so I've had a snack with no insulin this week and fingers crossed it'll stop it happening this time. Not so bothered if its higher tonight.

This is definitely familiar to me. If I have a hypo I'm very likely to have at least another one that day. Haven't got a clue as to why though

sounds a bit like the somogyi effect, i used have these a lot during my teenage years. my specialist used to tell me to run a little higher after a hypo because the body needs to recharge and there was a chance of another hypo if the cells haven't recharged enough so as soon as you exert yourself it is quickly burnt off.
