Diabetes symptoms are determined primarily by the type and stage of diabetes. For instance, the onset of type 1 symptoms usually begins abruptly.
Also, the symptoms of type 1 diabetes tend to occur much earlier (usually before age 30) than type 2.
On the other hand, the symptoms of type 2 diabetes usually occur gradually.
In the first ten years or so of the disease, symptoms develop gradually and may not even be noticeable.
Type 2 is the more common form of diabetes mellitus and affects approximately 90% of all diabetic patients. It also tends to occur later (after age 40) and peaks between ages 60 to 65. During its early stages, there may be no noticeable signs of diabetes. Some patients may only discover that they have this condition during routine medical check-up.
This underscores the importance of having regular (at least annual) medical evaluations. Diseases can be detected much earlier, which helps to facilitate more effective treatment and/ or management of certain conditions, such as diabetes mellitus.
During its early stages, when the symptoms of diabetes have not yet been manifested, there can be considerable damage to the body's organs. In some cases, when diabetes symptoms become noticeable, the damage to some organs can be so extensive that treatment or management becomes much more difficult. For instance, there could be irreversible damage to the eyes, heart and kidneys.
When the body has inadequate amounts of insulin or is unable to effectively use insulin, the metabolism of protein, fat and carbohydrate is affected. Classic diabetes symptoms include the following:
If you experience a number of the above "classic" diabetes symptoms, please check with your doctor. It is always advisable to check with your doctor regularly (at least once a year) for a full medical evaluation. This will increase the chances of early detection of diabetes mellitus (and other diseases); even before the classic diabetes symptoms become noticeable.
