Is Diabetes Hereditary?
Scientists estimate that the child of a parent with noninsulin-dependent diabetes has approximately a 10 to 15 percent chance of developing noninsulin-dependent diabetes. If both parents have diabetes, the child's risk of having the disease increases. The child's health habits throughout his or her life will affect the risk of developing diabetes. Obesity, for example, may increase the risk of diabetes or cause it to occur earlier in life.
Noninsulin-dependent diabetes in a parent has no effect on the chances that his or her child will have insulin-dependent diabetes, the more severe form of diabetes.
Stress and Illness
One way the body responds to stress is to increase the level of blood glucose. In a person with diabetes, stress may increase the need for treatment to lower blood glucose levels. Illnesses such as colds and flu are forms of physical stress that a doctor can treat. The doctor will advise the person to drink plenty of fluids. When blood glucose is high, the body gets rid of glucose through urine, and this fluid needs to be replaced.
If nausea makes eating or taking oral diabetes drugs a problem, a doctor should be consulted. Not eating can increase the risk of low blood glucose, while stopping oral medications or insulin during illness can lead to very high blood glucose. A doctor may prescribe insulin temporarily for someone with diabetes who can't take medicine by mouth.
Great thirst, rapid weight loss, high fever, or very high urine or blood glucose are signs that blood sugar is out of control. If a person has these symptoms, a doctor should be called immediately.
Like illness, stress that results from losses or conflicts at home or on the job can affect diabetes control. Urine and blood glucose checks can be clues to the effects of stress. If someone finds that stress is making diabetes control difficult, a doctor can advise treatment and suggest sources of help.
