What Is Happening To Me - Please Help

Are you Type 1 or Type 2 ? Readings between 13 to 18 are high, whereas readings 4 to 6 are on the lower side but in range; however if you are used to being high, your body thinks it's too low when it drops but is still in range. An overly high carb fix (like the coke, candy and toast) will rapidly raise your blood sugar and then it will rapidly fall. When I fall too low I will have only one teaspoon of sugar in a tea or maximum 2 carrots, or half banana or apple and that will raise my sugar without sending it too high. It takes about 20 minutes to feel the effect but it's better to sit quietly and wait than to go too high and find yourself then falling too low again. I'm not an expert so hopefully others will be along soon who have more knowledge than I do.

When it is hot your insulin will work faster so that could be why things have changed.
Agree with the others here that 13-18 is hyper and will be damaging in the long term whether you are type 1 or 2!

It woukd be helpful to know if you are prescribed insulin injections or not.
As @Jaylee has mentioned heat can make us more insulin sensitive particularly to injected insulin which may be absorbed better from increased blood running through tissues under your skin to radiate heat outward. More blood through = more insulimn absorbed.
A tepid shower may cool you down better than a cold one but the insulin absorption may still be higher than usual.so speaking with your doctor/nurse or emergency line to adjust insulin doses or doses of tablets that might affect bsls and check on how your fluid intake was goingmay be required.
Jusy a nagging thought: depending on things like how long you have had diabetes, how well controlled, in the heat you can become dehydrated, which can cause the kidneys to come under stress and then start to not work well including not releasing out through the urine the insulin once it has done its work. Build up of insulin can mean more insulin in your blood stream to cause lower BSLs.
So not passing urine in more than 10 hours, or only passing small amounts in 16 hours were signs i was taught to report to my doctor, nurse or hospital. Things would be worse quicker if i was vomiting, had diahhorea or unable to drink water.
So lots of water regularly, to keep oassing urine every few hours and even some fluids like Gastrolyte or similar used for children was suggested. Best Wishes on things getting better soon.

Hi. I’m sorry i’ve not had chance to post in any introduction posts yet but i really need help & advice

Ok so today the weather has been unbearable. I did some housework & had a shower this afternoon and since dinner my blood sugars have dropped ridiculously.

I have tried 2 tiny can of regular coke, a candy cane & toast but its only raising my sugars before plummeting them again.

I usually run between 13 - 18 but the sugars right now are hovering between 4 - 6 which is unusual for me

I’m starting to panic so if anyone can help it would be much appreciated

Hi there, your readings are quite high, so dropping in the heat often happens, sounds like you had a 'false hypo' because of the continuous high readings.
Are you on any diabetes medication and can you tell us what type you are please ?

I’m on the following:

Insulin: Tresiba (long acting) & apidra (fast acting)

Tablets: sukkato (metformin equivalent)

Bs reader system: Libra (sensor & scanner)

Hi @KateBaggins81 , and welcome to the forum. As above there are a number of reasons; yesterday was very hot and I found that my insulin was absorbed very quickly and sent me hypo, followed be high reading (may have over-corrected), overall yesterday was quite difficult to manage. Its cooler today and much easier. Usually I aim for around 5-8, 4 is ok, but above 10 and I would be correcting. 18 for me is really quite high.
