Hyperosmolar Coma

Overview of Hyperosmolar Coma

Hyperosmolar coma is a complication of diabetes. It is seen most frequently in older people. These individuals usually have diabetes that does not require the use of insulin. When other illnesses develop, such as stroke or infection, they often become dehydrated as well. The combination of this disorder with dehydration leads to very high levels of glucose in the blood. This may severely affect the brain as well as other organs.

Causes of Hyperosmolar Coma

Hyperosmolar coma is caused by a marked increase in the glucose level of the blood. This hyperosmolarity leads to fluid shifts from the cells. Elevated levels of glucose also produces increased urine output, further aggravating the dehydration.

Signs and Symptoms of Hyperosmolar Coma

This disorder primarily is seen in older people with non-insulin dependent diabetes. There is a slow impairment of consciousness. Prior to the change in consciousness or concurrent with it is the onset of confusion. Eventually the disorder may result in the development of coma.
