There's no substitute for the body's own blood sugar control
mechanism, but insulin pumps may be the next best thing, say diabetes
An insulin pump is a compact, pager-sized, computerized device
that can be worn on a belt. It is connected to the body via a flexible plastic
tube through which insulin is delivered. The pump releases insulin in a steady,
continuous background or "basal" dose, but also allows the wearer to
add an additional dose, or "bolus" of insulin when needed, such as
before a meal or snack.
About two years ago, when Anne Tierney learned she had type 2 diabetes, it
galvanized her. “My diagnosis came as a shock,” says Tierney, who was then
about 40 pounds overweight. “I used to eat chocolate all the time. The day I
was diagnosed, I quit.” She also consulted a nutritionist and hired a personal
trainer. “I knew I had to take action,” recalls Tierney, 51, director of
corporate gifts for Halls Crown Center in Kansas City, Mo.
Her action plan was in keeping with the latest research on...
"It provides more stable insulin deliveries and smoothes
out glucose fluctuation compared with injections," explains Howard A.
Wolpert, MD, senior physician and director of the insulin pump program at the
Joslin Diabetes Center in Boston, in an interview with WebMD. "I think the
advantage from a lifestyle standpoint is what attracts many people, because it
does allow people much more flexibility in terms of eating times."
Although people with diabetes can now use an ultra long-lasting
insulin (insulin glargine) that releases an even basal dose for 24 hours after
injection, Wolpert notes that "with glargine people still need to take
multiple injections whenever they're going out to eat or whenever they're going
to have a snack. With a pump it's much more convenient in terms of just having
to press a button and get insulin delivered. For people eating out, if they're
not certain what they're going to be eating they can take an initial bolus or
pulse of insulin, and as the meal proceeds they can take further insulin
depending on their [food] intake."
The pump also can help control the release of glucose during
exercise, Wolpert says. Insulin levels normally drop during exercise to allow
the release of stored glucose for use by the exercising muscles, but people who
inject insulin may find it hard to predict how much insulin to have on board
prior to exercise. In contrast, those who use pumps can more easily adjust the
dose to their body's minute-to-minute-demands. "For the motivated patient
who wants to lose weight through exercise, one can do it much more effectively
if one's on a pump than say on insulin injection," Wolpert tells WebMD.
But while the insulin pump is for many people an improvement
over multiple daily injections, it requires a dedicated and savvy operator to
make it work. The user still has to perform multiple daily blood tests to check
for glucose levels, and must know how to program in the right insulin dose
after each test; currently available pumps can neither sense current glucose
levels nor can they automatically adjust insulin levels.
"It's just a different tool for delivering insulin; the
person still needs to input the doses, and to get the most out of the pump one
still has to be pretty knowledgeable and skilled in diabetes self-management.
It's not a tool for the novice," Wolpert says.
"It isn't right for everyone," agrees Michael Freemark,
MD, professor of pediatrics and chief of the endocrine and diabetes division at
Duke University Medical Center in Durham, N.C. "It requires a strongly
committed family and an experienced diabetes team."

Your level is currently
If the level is below 70 and you are experiencing symptoms such as shaking, sweating or difficulty thinking, you will need to raise the number immediately. A quick solution is to eat a few pieces of hard candy or 1 tablespoon of sugar or honey. Recheck your numbers again in 15 minutes to see if the number has gone up. If not, repeat the steps above or call your doctor.
People who experience hypoglycemia several times in a week should call their health care provider. It's important to monitor your levels each day so you can make sure your numbers are within the range. If you are pregnant always consult with your health care provider.
Congratulations on taking steps to manage your health.
However, it's important to continue to track your numbers so that you can make lifestyle changes if needed. If you are pregnant always consult with your physician.
Your level is high if this reading was taken before eating. Aim for 70-130 before meals and less than 180 two hours after meals.
Even if your number is high, it's not too late for you to take control of your health and lower your blood sugar.
One of the first steps is to monitor your levels each day. If you are pregnant always consult with your physician.
