Default Dipping blood sugars cause surprisingly irregular heart rhythms in diabetics

Dipping blood sugars cause surprisingly irregular heart rhythms in diabetics - News releases - News - The University of Sheffield


• Research unveils clues to ‘Dead in Bed’ cases where young people without any history of long-term complications die suddenly from diabetes.

• Low blood sugar levels lead to heart rhythm disturbances and even life-threatening heart attacks.

Dangerous overnight blood sugar levels often go undetected and cause prolonged periods of heart rhythm disturbances in older patients with Type 2 diabetes and associated heart problems, new research reveals.

The findings from the research – led by Professor Simon Heller of the University of Sheffield’s Department of Human Metabolism and Sheffield Teaching Hospitals NHS Foundation Trust - could offer vital clues to the mechanism by which low blood sugar levels could contribute to life-threatening changes in heart rhythm, a major risk for patients with diabetes.

They also shed important new light on the ‘Dead in Bed’ syndrome – where young people without any history of long-term complications die suddenly from the disease.

Previous studies have apparently ruled out a direct effect of hypoglycaemia (very low levels of sugar in the blood) as a cause of death in patients with Type 2 diabetes.

Few of the patients taking part in the present study reported symptoms of low blood sugar levels or irregular heartbeats – and they were only detected through continuous glucose monitoring and electrocardiograms used by Sheffield researchers which tracked blood glucose levels and heart rates over a week in a group of older patients with Type 2 diabetes and a history of cardiovascular disease.

And how many "dead in bed" victims did they have during this study? Sounds like they're fishing for more "reasons why you should not let your BG get to low" scare material.

Mbuster,

There doesnt seem to be allot of concern about low blood sugar in posts here. When I see my BG in the low 70s, I'm not thrilled because I know my meter could easily be 10 points high. When I see readings in the low 60s, I'm straight up concerned and will take immediate steps to address. (I've not seen 60s since getting off met)

I'd always been led to believe that high BG will harm you over time, and that low BG can harm you today.

Wondering if I'm missing something, or just flat out wrong about these numbers being too low? I don't think that article defined what low BG levels are, which is part of why I'm asking.

Unless people are on insulin or other glucose-lowering drugs like sulfonylureas, going low shouldn't be an issue. If you drop into the 40s, then get to ER. 60s/70s are normal non-diabetic levels - lowish, but still with normal limits.
Quote:
Source: Blood sugars under 70 mg/dl (3.9 mmol/L) are considered to be hypoglycemic. However, if you are not on insulin or a drug that causes your pancreas to secrete insulin, a blood sugar slightly below this range, while it might be uncomfortable, is not dangerous unless there is evidence that it is continuing to drop. The dangerous levels of low blood sugar--the hypos that require a visit to the ER--are those in the 40 mg/dl (2.2 mmol/L) range and lower. At those levels unconsciousness and brain damage can occur.

I can't speak for anyone but me, but no there is not much concern on my part for being in the 60s or even the high 50s. When I see 60s (seldom but it happens sometimes), or 50s (even more of an oddity for me, but has happened a couple of times), is not enough of a concern to make me want to try to do anything differently and intentionally run higher, because my meter could also be reading 10 points high.

The study's conclussion sounded like there are potentially many cases of finding T2s dead for no explained reason until now. How many unexplained deaths has anybody here heard of? Maybe they are just keeping it secret from me.

You will have symptoms at 60 ,but can eat something to bring the levels up.

Not always, Patti, and not everyone. There are people who are hypo-unaware who don't feel any symptoms - even if they drop dangerously low.

Hypoglycemia Unawareness

You're right. I'm new here and I didn't think before I responded. I had reactive hypoglycemia before diabetes. My sugar levels always bounced back up to 60 pretty fast, but I didn't recover as fast. I would go from 30 to 60 in a half hour. Think of how foolish I felt in the emergency room ....and now in this forum!!! My sugar was 24 and I was in a coma. I came out of the coma, my sugar bounced back up to 70. I will read Hypoglycemia Unawareness. I'm probably the opposite. I'm trying to know the difference. I thought I was better.

Also as you can read here:

http://diabetesupdate.blogspot.com/2...hypos.html?m=1

If docs want pregnant women to stay as low as 60, what's the danger of hypo?

Also, since our bodies regulate our BG in a +/-30 point range from our baseline level, a "technical" hypo of even 55 could be a normal BG if the baseline is 75-85. It's also why someone keeping their baseline in that 75-85 range will feel terrible if they go above 110. That 110 is outside the body's comfort zone.

Consider me paranoid from having hypoglycemia since I'm 15. If I see 55 on my meter I'm bugging out. When I was pregnant, I was told to stay within the normal range and stay on my diet. Maybe for pregnant diabetics it is different.
