While it's very easy to test for diabetes symptom , a simple blood glucose test is the determining factor, diabetes may not be easily recognized at first since so many of its symptoms are also common complaints for people who do not have diabetes. For this reason, diabetes may often go undiagnosed for a period of time before it is discovered and treated, if it is discovered in time to prevent complications. Frequent urination, particularly at night, can also be a symptom of diabetes, but this symptom alone would not necessarily suggest the disease either. This symptom would also have to become pretty annoying and recurrent before it would prompt most people to consult a doctor. Unexplained weight loss is another possible sign of diabetes but again, not a significant indication that the individual necessarily has diabetes. In many cases, people who want to lose weight would consider this an unexpected blessing and might not consult their doctor unless they had lost a considerable amount of weight over a period of time. Skin infections, wounds that are slow to heal, particularly sores on the feet and ankles, and recurrent vaginal infections (in women), are signs of possible diabetes that are somewhat more likely to draw attention and result in a diagnosis.

Blurred vision and tingling or numbness in the hands or feet are also possible indicators of diabetes, and since these symptoms can be troublesome, are more likely to result in medical attention and diagnosis.

Individuals who experience several of the above-mentioned symptoms may have good reason to suspect diabetes, particularly if they are in any of the higher risk categories, and should contact their physician to request a simple blood glucose test which can either confirm or rule out diabetes.

Type 2 diabetes develops slowly and the symptoms are usually less severe. Some people may not notice any symptoms at all and their diabetes is only picked up in a routine medical check up. Some people may put the symptoms down to 'getting older' or 'overwork'.

Type 1 diabetes develops much more quickly, usually over a few weeks, and symptoms are normally very obvious.

In both types of diabetes, the symptoms are quickly relieved once the diabetes is treated. Early treatment will also reduce the chances of developing serious health problems.
