How to prevent pre-diabetes or borderline diabetes
The most noticeable increases in incidences of diabetes is in the elderly — 65 and older. After visiting with their doctor they are usually placed on medication to lower their glucose levels. They are also told that they should begin consuming a healthier diet and start an a consistent exercise program. The combination of all these protocols can lead to hypoglycemia or low blood sugars.
There are a host of issues associated with hypoglycemia that could be avoided if the medical community would advise their patients on an individual basis as opposed to being given generalized information and treatment.
The following article highlights studies conducted at The Yale School of Medicine which points out that it’s important to treat diabetes on an patient by patient basis as opposed to a standardized, one size fist all protocol.
Older diabetics may be pushing blood sugar too low
By Kathryn Doyle
(Reuters Health) – Older diabetics may sometimes do too good a job at keeping their blood sugar down, according to a new study.
Regardless of age, people with diabetes are taught to keep their blood sugar below certain target levels. But many diabetics over 65 who have other health concerns may be at risk for pushing it too low, according to a new study.
Particularly for older adults with multiple serious illnesses and functional limitations, the risks of low blood sugar, or hypoglycemia, may outweigh the benefits of tight blood sugar control, the authors write.
“Older people are more susceptible to hypoglycemia,” said lead author Dr. Kasia J. Lipska of the Yale School of Medicine in New Haven, Connecticut.
“As people age, their kidney function deteriorates and drugs (like insulin) may not be eliminated from the body as efficiently,” which can lead to low blood sugar, she told Reuters Health by email.
Often, people with low blood sugar don’t realize they have it. Symptoms can include double or blurry vision, rapid heartbeat, headache, hunger, shaking or trembling, sweating, tiredness or weakness or feeling faint, trouble sleeping, unclear thinking, and other problems. Severe low blood sugar can cause seizures and brain damage.
Intense diabetes treatment, which the study showed many older people are doing, increases the risk for hypoglycemia two to three fold, Lipska said.
Her team used data on 1,288 diabetics age 65 or older, from the National Health and Nutrition Examination Surveys from 2001 through 2010.
Based on their ability to complete activities of daily life, about half of the participants were generally healthy, 28 percent had “complex or intermediate” health and 21 percent had “poor” health.
To see how tightly these patients were controlling their blood sugar, the researchers measured a substance in the blood called hemoglobin A1c. A1c reflects a person’s average blood sugar levels over the past three months.
A person without diabetes would have an A1C reading under 5.7 percent. People with pre-diabetes may have a reading between 5.7 and 6.4 percent. Levels above that qualify for a diabetes diagnosis.
Most people with diabetes aim to keep the number under 7 percent, according to the National Institutes of Health.
Almost two-thirds of the older adults in the study maintained tight blood sugar control, keeping their A1C levels at 7 percent or lower, according to results in JAMA Internal Medicine.
“Tight blood sugar control, or aiming for a hemoglobin A1c below 7 percent, increases the risk for hypoglycemia, or low blood sugar reactions,” Lipska said.
She and her coauthors did not assess how many people are actually harmed by diabetes overtreatment.
“We tried in our study to estimate how many people are treated in a way that is unlikely to benefit them and more likely to harm them, but we do not have data on follow-up to see what exactly happened to them,” she said.
A 2011 study in the Journal of the American Geriatrics Society found that more than three million older people with diabetes would be eligible for reduction in medication if glucose targets were raised.
“It is not clear to me if doctors do enough to assess the burden of medications with their patients or know about hypoglycemic events,” said Dr. Elbert Huang of The University of Chicago, coauthor of the 2011 study.
“There is likely to be inadequate communication,” he told Reuters Health by email.
Hypoglycemia is a well-known consequence of tight blood sugar control, but its importance has been minimized largely due to pharmaceutical interests in keeping patients on antidiabetic drugs, according to Dr. David Aron of the Louis Stokes VA Medical Center in Cleveland, Ohio.
“I think this is actually a case of willful ignorance,” Aron told Reuters Health by phone.
Hypoglycemia is a major cause of emergency room visits, he said. The symptoms can be subtle, and older people may have trouble recognizing them, Aron said.
Though the healthcare system has been slow to act on the hypoglycemia problem, there are a number of education initiatives aimed at clinicians and patients currently underway or planned for the near future, he said.
Diabetes treatment should be tailored to each individual patient, taking into account their age, other health conditions and preferences – the exact A1C target will vary, Lipska said.
Patients should ask their doctors what the right target is for them, she said.
“Think about what your health goals are and discuss these with your doctor,” Lipska said. “You have to be as informed as possible about these decisions, and comfortable that the decisions are right for you.”

P.S. It’s important to have a candid discussion with your doctor to talk about such things as your activity level and the types of food you consume regularly and your social interactions . . . . . the specifics of your current lifestyle.
P.P.S. If you are pre-diabetic you must begin an exercise program in-order to avoid the awful complications of diabetes. Visit How to Prevent Pre-diabetes for information on how to prevent pre-diabetes with exercise.
