and possible treatments for diabetes

therapy may offer the opportunity to prevent diabetes in susceptible
individuals, but this is likely to be some time in the future.
PAINFUL INSULIN INJECTIONS
automatic insulin pump is' already available, which means that fewer
injections are needed. The needle is sited under the skin, and in current
models only needs to be changed every few days. It is connected to a small
electrical pump that attaches to a belt or waistband and is approximately
the size of a pager. When insulin is needed, the user presses a button and
insulin is delivered through the needle.
the future microchip technology will probably enable automatic blood
glucose level readings to be taken, and the amount of insulin needed to be
automatically delivered through a single device. Other ideas in the
pipeline include painless ultrasonic injections, and the possibility that
insulin may be able to be given through an inhaler device rather than
cell transplantation, where insulin-making cells from someone without
diabetes are transplanted into someone with diabetes, are already showing
good results in scientific studies.
transplanted cells are extracted from the bodies of donors and kept alive
and purified, before being injected into the person with diabetes through
a main vein connected to the liver. These cells are then carried in the
bloodstream and 'nested' in the liver. Despite not being in the patient's
pancreas they still manage to produce insulin.
PAINFUL PIN-PRICK BLOOD MONITORING
wrist-watch monitor has recently been developed, which avoids painful
pin-prick monitoring. It's worn on the wrist and sits on top of a
disposable gel disc that contains the same enzyme used to monitor glucose
levels in home monitors. Instead of testing blood directly, it draws
glucose into the disc using a tiny electric current that flows between two
terminals beneath the watch. Charged molecules move towards the electrodes
as the current passes through the skin, dragging glucose molecules along
