There are many possible dangers of not having a diabetes diagnosis done at the first sight of symptoms of the disease. If a person has chronic problems with frequent urination or an always present hunger or thirst, these may be the signs that the person is in the beginning stages of diabetes and may wish to get tested. There are a number of tests that doctors use to make a diagnosis and they are very accurate in determining whether the person has normal blood sugar levels, or is in a pre-diabetic state, or has full diabetes
The two tests that are most commonly used for a diagnosis are the FPG and the OGTT. Both of these tests work on the basis of having the patient for at least eight hours and then a glucose reading is taken. In the case of the OGTT, a glucose drink is given to the patient two hours before the reading is taken to monitor the exact amount of sugar that is in the blood. For this reason, the OGTT is a more sensitive test and is a more accurate diagnostic tool. Pregnant women are often administered the OGTT test to determine whether gestational diabetes is present.
Testing should not be limited to only those people that have shown symptoms of this condition. In addition, anyone who is obese or has any of the high-risk factors will need to have a diabetes test done at regular intervals. For some people, diabetes has few symptoms until there is a major problem. This is why it is important to test early and begin treatment as soon as the problem has been identified. If the disease is allowed to grow worse unimpeded without a diagnosis, it could result in serious problems, such as diabetic nephropathy or diabetic retinopathy.
