  • 26. Medications • Tablets People with Type 2 diabetes may not be able to adequatelycontrol their blood glucose levels through diet, exercise andlifestyle changes alone.  Therefore, in many cases diabetictablets are required.  There are a variety of tabletsavailable, which work in different ways.  These include:•  • Tablets to increase insulin output from the pancreas eg:Glipizide, Glibenclamide.• Tablets to reduce insulin resistance eg: Metformin• Tablets that stop the absorption of carbohydrates fromthe bowel eg: Acarbose.•  
  • 27. BLOOD GLUCOSE TESTING ("BLOOD SUGARS")To enable blood glucose levels to be tested, adroplet of blood is obtained from a small fingerprick test and is measured on a special testingstrip.  The results will help to determine howmuch medication is required, how much exercisecan be undertaken and what foods should beeaten.  This simple home test needs to beperformed regularly, in some cases up to severaltimes per day.  It is important to follow theguidelines given by the treating doctor as to howoften they should be done.
  • 28. InsulinIn people with Type 1 diabetes and in some people with Type2 diabetes, insulin injections are required.  There are anumber of different types of insulin available that vary inthe duration of time they are effective.Insulin is injected under the skin of the abdomen or thighand can be administered by using a disposable syringe andneedle, or a preloaded insulin “pen”. Insulin can also beadministered by a pre-programmed insulin pump. An insulinpump is a small battery powered device into which insulincan be a loaded. The insulin is pumped into the abdomen viaa thin plastic tube connected to a very thin plastic needlethat is secured under the skin.
