The purpose of this research study is to find out how blood sugar levels change during the day and night in people living with spinal cord injuries (SCI) and then to compare that with people who do not have a spinal cord injury.

As people with SCI get older they become more likely to develop health problems, just like everyone else. However, SCI increases the risk of certain problems. The amount of time post-SCI can also increase the risk of certain problems. This research project will focus on identifying the patterns of changes in blood sugar levels after SCI. Sugar in the blood is the important source of energy for the body. Too much sugar in the blood is known as hyperglycemia and not enough sugar in the blood is known as hypoglycemia. Under healthy conditions, the amount of sugar in the blood is automatically regulated so that a steady level is maintained. After SCI, however, this automatic regulation is damaged. The likelihood of experiencing too much or too little blood sugar is increased. Over time, having too much blood sugar can lead to the development of diabetes. In just the opposite situation, individuals with SCI can begin to experience more frequent episodes of too little blood sugar, which can lead to acute emergency situations.

The pattern of how blood sugar levels change during a typical 24-hour time period in persons with SCI is not known. There may be unknown factors that affect blood sugar levels. In order to find out that information, this study will involve continuously monitoring blood sugar over a 3-day period in a variety of persons with SCI. A non-invasive, wireless monitoring system will be attached to the abdomen. This system records blood sugar levels every 5 minutes. The information gathered from this observational study is vital to the understanding of how SCI alters the regulation of sugar levels in the blood and to the subsequent medical management of this population.
