Diabetes is a manageable condition if controlled properly. However, when diabetes isn’t managed it can lead to some significant health problems. Having elevated blood glucose levels over a long time can be especially harmful. Currently, it is completely unknown to scientists why complications occur. What is known is that high blood glucose levels can damage blood vessels and nerves which can affect the entire body. It is common for most people with diabetes to develop complications after a few years. Nevertheless, with living a healthy lifestyle and proper monitoring of blood glucose levels can help people possibly avoid complications. Complications are much more likely to develop with an unhealthy lifestyle, not monitoring blood glucose levels or or going undiagnosed for several years. As a result, people with both type 1 and type 2 diabetes need to be fully aware of potential complications and understand them. This is essential because spotting symptoms of complications means that they can be effectively treated.
