Type 2 diabetes: Value of home blood sugar monitoring unclear

Observe me on Twitter @RobShmerling

It’s a central tenet of diabetes therapy: monitor the blood sugar carefully, then alter your food plan, train, and medicines to maintain it in an excellent vary. And that is smart. Poorly managed blood sugar is a serious danger issue for diabetic issues, together with kidney illness, imaginative and prescient loss, and nerve harm.

Whereas efforts to fastidiously monitor and management the blood sugar in diabetes are worthwhile, “tight management” isn’t at all times useful — and it could even trigger hurt. For instance, in research of individuals with longstanding sort 2 diabetes, the sort that normally begins in maturity and is very linked with weight problems, these with the tightest management both had no profit or had larger charges of heart problems and dying. In the meantime, research of individuals with sort 1 diabetes — the sort that tends to start out throughout childhood as a consequence of an immune assault in opposition to the insulin-producing cells within the pancreas — recommend that tight management might assist shield in opposition to heart problems. So, it appears the advantages and dangers of tight management rely upon the scenario.

House blood sugar monitoring for sort 2 diabetes

Individuals with diabetes are sometimes suggested to verify their blood sugar ranges at dwelling by pricking a finger and testing the blood with a glucose meter. They’ll assessment the outcomes with their docs over the cellphone, on-line, or on the subsequent workplace appointment. The worth of this for folks with sort 2 diabetes is unsure.

In a research printed in JAMA Inside Drugs, researchers enrolled 450 folks with Sort 2 diabetes, none of whom had been taking insulin. They had been randomly assigned to one in every of three teams:

  • no self-monitoring of blood sugar
  • as soon as every day self-monitoring of blood sugar
  • once-daily self-monitoring of blood sugar with “enhanced suggestions” from their blood glucose meters with messages meant to coach and encourage the research volunteers.

After one yr these researchers discovered that, in contrast with these not self-monitoring blood sugar, those that self-monitored had no enchancment within the management of their blood sugar, and had no enchancment in measures of high quality of life.

So what?

The impression of this research might be huge. Of the enrolled research topics, three-quarters routinely checked blood sugar at dwelling. If that’s typical of individuals with sort 2 diabetes, these findings might permit hundreds of individuals to cease sticking themselves and get monetary savings on monitoring gear, with no sick results on their well being.

However even when these findings are confirmed, there could also be conditions when dwelling monitoring remains to be helpful and vital. For instance, dwelling monitoring could be a good suggestion when folks like these on this research:

  • develop an an infection
  • change the dose of their diabetes medicines
  • add or cease taking one in every of their medicines
  • achieve or lose a big quantity of weight
  • start taking insulin.

This research didn’t look at these conditions and so couldn’t draw conclusions about them. It’s additionally value noting this research lasted just one yr. It might take longer to see a profit from dwelling monitoring. Lastly, this research didn’t embrace people with sort 1 diabetes, so the outcomes don’t apply to them.

The underside line

This new research means that docs treating folks with sort 2 diabetes might not must suggest routine self-monitoring of blood sugar. Nevertheless, whereas which may be true for the common individual with sort 2 diabetes who isn’t taking insulin, we’ll want extra research and longer-term research to establish which individuals with sort 2 diabetes will profit most from dwelling monitoring and when it’s simply not well worth the effort.
