According to a recent government-funded study, Americans with diabetes may be losing momentum in controlling the illness after years of progress.
Diabetes Is Still Out Of Control Even After Years Of Improvement
Researchers discovered that between 1999 and the early 2010s, U.S. individuals with diabetes made significant gains: an increasing percentage had blood sugar, blood pressure, and cholesterol readings that were within guideline ranges.
Since then, the situation has shifted: progress in lowering cholesterol has stagnated, and fewer individuals have control of their blood sugar and blood pressure than a decade ago.
According to the researchers, the findings are troubling since the trends might put more Americans at risk of heart disease, stroke, and other diabetic consequences.
This is depressing, according to lead researcher Elizabeth Selvin, a professor at the Johns Hopkins Bloomberg School of Public Health in Baltimore. Not only are control rates plateauing, but also they are deteriorating.
Selvin and her colleagues published the findings in the June 10 edition of the New England Journal of Medicine.
According to the American Diabetes Association, approximately 34 million Americans have diabetes in 2018. The great majority had type-2 diabetes, which occurs when the body’s ability to utilize insulin, a hormone that regulates blood sugar, deteriorates.
As a result, blood glucose levels skyrocket. Uncontrolled blood sugar levels can cause damage to blood vessels and nerves over time, resulting in consequences such as heart disease, stroke, renal failure, and eye illness.
Furthermore, persons with diabetes frequently have additional chronic illnesses, such as high blood pressure and excessive cholesterol, which can exacerbate the difficulties.
So, why is it that control of those circumstances is deteriorating?
The study does not make it apparent, but Selvin suggested some alternatives. Three clinical investigations published in 2008 and 2009 called into doubt the usefulness of strict blood sugar control: Diabetes patients on that regimen had no additional reduction in their risk of heart disease or stroke, but they did have a higher chance of potentially severe blood sugar dips.
These trials investigated the impact of very stringent regulation of patients’ A1C levels. This is a calculation of a person’s average blood sugar levels during the previous three months.
The studies intended to reduce patients’ A1C levels to less than 6.5 percent or 6 percent, as opposed to the typical 7 percent.
Following the publication of the findings, several doctors began to relax their stance on strict blood sugar management.
Selvin believes that what they are experiencing currently is an overcorrection.
This is because fewer Americans are now meeting even the normal A1C goal of less than 7%.
Selvin’s team discovered that between 1999 and the early 2010s, the proportion of diabetes patients fulfilling that goal increased from 44% to 57%. By 2018, that figure had dropped to 50%.
Blood pressure management patterns were comparable. Over the previous period, the percentage of diabetes patients attaining blood pressure objectives increased from 64% to 74%. Following that, the figure fell to 70%. (Control was defined as a blood pressure less than 140/90 mm Hg.)
The causes are unclear, although Selvin noticed that the pattern mirrors that of the general population in the United States.
Dr. Joanna Mitri works as an endocrinologist and research associate at Boston’s Joslin Diabetes Center. She played no part in the research.
According to Mitri, when the results of the rigorous glucose (blood sugar) reduction experiments were published, treatment guidelines switched from being glucose-centric to a broader focus on managing other cardiovascular risk factors as well.
A somewhat higher A1C may be appropriate for some individuals, she noted, such as an older adult at risk of low blood sugar episodes. For some patients, keeping A1C below 7% may be the appropriate target.
Selvin, like Mitri, urged that patients discuss their treatment objectives with their doctors and inquire whether they are on “optimal” care.
