Diabetes pills are not a form of insulin. They help the body make more insulin or use insulin more effectively. This helps reduce the amount of glucose in the bloodstream between meals and at night, which helps keep blood sugar levels under control. Diabetes pills can also help with weight loss and help improve cholesterol and triglyceride levels, which tend to be abnormal in people with type 2 diabetes.
Because the drugs listed above act in different ways to lower blood glucose levels, they may be used together. For example, a biguanide and a sulfonylurea may be used together. Many combinations can be used. Though taking more than one drug can be more costly and can increase the risk of side effects, combining oral medications can improve blood glucose control when taking only a single pill does not have the desired effects. Switching from one single pill to another is not as effective as adding another type of diabetes medicine.
Another factor to consider when determining when to take your diabetes medicines is how well you can follow the regimen your doctor recommends. For any drugs to be effective, you have to take them. Ideally, your medication schedule should be incorporated into your daily routine; only having to remember to take your diabetes pills once a day may make things easier for you. Not much evidence is available that taking saxagliptin and glipizide at different times will provide a better blood-glucose-lowering effect. The most important thing is to take them regularly and without missing any doses. In addition to taking the diabetes medicines you’ve been prescribed, other ways to help improve your blood glucose levels are to engage in healthy lifestyle habits, such as regular physical activity and a healthy diet.
Treatment plans are designed around the pattern of insulin normally supplied by the pancreas throughout the day in someone without diabetes. In general, this involves providing a fairly steady "background" level of insulin to control blood sugar levels between meals and overnight, along with doses of rapid- or short-acting insulin to handle the fast rises in blood sugar that occur with meals.
This seems hard to do, but really it’s not if you know one secret: Replace snacking with something far more satisfying — fat. That’s right, the government is wrong to recommend a low fat diet. Fat is what makes you feel full until your next meal. Take away the fat, take away the full. Don’t go to an extreme, but do lean strongly toward a high-fat low-carb diet.
