|What is type 2 diabetes?
People with diabetes are not able to make enough insulin and/or respond normally to the insulin their body does make. When this happens, sugar (glucose) builds up in the blood. This can lead to serious medical problems including kidney damage, amputations and blindness. Diabetes is also closely linked to heart disease. The main goal of treating diabetes is to lower the level of your blood sugar as close to normal as possible.
How is type 2 diabetes usually controlled?
High blood sugar can be lowered by diet and exercise, by a number of oral medications and by insulin injections. Before taking biguanidas (metformin hydrochloride tablets) you should first try to control your diabetes by exercise and weight loss. Even if you are taking biguanidas, you should still exercise and follow the diet recommended for your diabetes.
Does Metformin work differently from other glucose-control medications?
Yes it does. Until Metformin was introduced, al¡ the available oral glucose-control medications were from the same chemical group called sulfonylureas. These drugs lower blood sugar primarily by causing more of the body's own insulin to be released. Metformin lowers the amount of sugar in your blood by helping your body respond better to its own insulin. Metformin (metformin hydrochloride tablets) does not cause your body to produce more insulin. Therefore, Metformin rarely causes hypoglycemia (low blood sugar) and it doesn't usually cause weight gain.
What happens if my blood sugar is still too high?
When blood sugar cannot be lowered enough by either Metformin or a sulfonylurea, the two medications may be effective taken together. However, if you are unable to maintain your blood sugar with diet, exercise and glucose-control medication taken orally, then your doctor may prescribe injectable insulin to control your diabetes.
Can Metformin cause side effects?
Metformin, Iike all blood-sugar lowering medications, can cause side effects in some patients. Most of these side effects are minor and will go away after you've taken Metformin for a while. However, there are also serious, but rare side effects related to Metformin.
What kind of side effects can Metformin cause?
If side effects occur, they usually occur during the first few weeks of therapy. They are normally minor ones such as diarrhea, nausea and upset stomach. Taking your Metformin with meals can help reduce these side effects. Although these side effects are likely to go away, call your doctor if you have severe discomfort or if these effects last for more than a few weeks. Some patients may need to have their dose lowered or stop taking Metformin (metformin hydrochloride tablets), either temporarily or permanently. Although these problems occur in up to one-third of patients when they first start taking Metformin, you should tell your doctor if the problems come back or start later on during the therapy.

Are there any serious side effects that Metformin can cause?
