does other illnesses cause you to have seizures
Any normally healthy person can have a single seizure under certain conditions. For instance, a sharp blow to the head may cause a seizure. Having one seizure does not always mean that a serious health problem exists. But if you have a first-time seizure, you should be checked by your doctor. It is important to rule out a serious illness that may have caused the seizure. Fever seizures (febrile convulsions) are the most common cause of a single seizure, especially in children. For more information, see the topic Fever Seizures. Epilepsy is a nervous system problem that causes seizures. It can develop at any age. For more information, see the topic Epilepsy. A seizure can be a symptom of another health problem, such as: 1  A rapidly increasing fever (fever seizure). 2  An extremely low blood sugar level in a person who has diabetes.
