Seizures and Coma
While most blood sugar dips can be quickly corrected, severe drops may require immediate action to avoid very serious complications, such as seizures, fainting, or even brain damage. For diabetics, dangerously low blood sugar can lead to a diabetic coma, which can also occur from high blood sugar. Early symptoms typically precede a coma, so it’s very important to raise your blood sugar gradually with glucose tablets or even regular soda.
