Can diabetes cause seizures? This is a common concern for people living with diabetes and their families. Seizures can be frightening, but understanding why they happen and how to prevent them is key to staying safe.
Can Diabetes Cause Seizures?
Yes, diabetes can cause seizures. The most common reason is a sudden drop in blood sugar, known as hypoglycemia. When blood sugar gets too low, the brain doesn’t get enough energy, which can lead to confusion, unconsciousness, or even seizures. This is a risk for anyone with diabetes, but especially for those on insulin or certain oral medications.
How Does Hypoglycemia Trigger Seizures?
Hypoglycemia (low blood sugar) happens when your blood glucose drops below 70 mg/dL. Symptoms may include sweating, shaking, confusion, and in severe cases, loss of consciousness or seizures. The brain relies on glucose for energy, so when levels fall too low, it can misfire, resulting in a seizure. This is more common in people with type 1 diabetes, but can also affect those with type 2 diabetes who use insulin or sulfonylureas.
Can High Blood Sugar Cause Seizures?
While less common, very high blood sugar (hyperglycemia) can also cause seizures. This usually happens in cases of diabetic ketoacidosis (DKA) or hyperosmolar hyperglycemic state (HHS), where blood sugar levels are extremely elevated. These emergencies are more likely in people who have missed insulin doses or are newly diagnosed.
Who Is at Risk?
- People with type 1 diabetes
- Children with diabetes
- Anyone using insulin or certain diabetes pills
- People who skip meals, exercise intensely, or drink alcohol without adjusting their diabetes management
How Can You Prevent Seizures?
- Monitor your blood glucose regularly, especially before driving or bedtime
- Carry quick sources of sugar (like glucose tablets or juice) in case of lows
- Work with your healthcare team to adjust medications if you have frequent lows
- Educate friends and family on what to do during a diabetic emergency
When to Seek Help
If you or someone you know with diabetes has a seizure, call emergency services right away. After recovery, talk to your doctor to adjust your diabetes plan and prevent future episodes.
