Dealing with low blood sugar from insulin for diabetes
Introduction
Low blood sugar (hypoglycemia) occurs in people with diabetes when the sugar (glucose) level in the blood drops below what the body needs to function normally.
Key points
- If your blood sugar drops below 3.6 millimoles per litre (mmol/L), you most likely will have symptoms, such as feeling tired, weak, or shaky.
- If your blood sugar drops very low (usually below 1.1 mmol/L) and you do not get help, you could become confused, drowsy, or even lose consciousness and possibly die. If you are pregnant, your baby could be harmed.
- Low blood sugar can develop if you take too much insulin, do not eat enough food or skip meals, exercise without eating enough, or drink too much alcohol (especially on an empty stomach).
- You can usually treat mild—and sometimes moderate—low blood sugar by eating something that contains sugar.
- You should teach your friends and co-workers what to do if your blood sugar is very low.
