A new implantable blood glucose monitor that is in the works is good news for diabetics who have to do finger sticks four times a day. According to the Great Beyond,
[r]esearchers have developed an implantable sensor that can monitor blood-sugar levels and send the data wirelessly to an external receiver. The team has used the device in pigs for over a year, and is hoping it will work successfully in humans with diabetes. Diabetics have to routinely measure their blood glucose by pricking their fingers and reading the levels with a small meter, in order to keep the blood sugar in check.
'Four finger sticks per day to measure glucose levels is the current standard of care, but blood glucose can go on significant excursions between sticks,' says David Gough, an author of the study from the University of California in San Diego. 'In contrast, the long-term implanted glucose monitor would provide continuous monitoring day and night.'
The sensor could aid diabetes patients to adjust the timing and dosage of insulin, as well as minimizing the risk of potentially life-threatening hypoglycaemia—low blood sugar—resulting from too high a dose of insulin or the insulin absorbing too fast. It could also help type-2 diabetes patients to balance their diet and exercise plans.
