Hypoglycemia, or low blood sugar, is a common concern for individuals living with diabetes. When the body doesn't produce enough insulin or can't use it effectively, glucose (sugar) builds up in the bloodstream and becomes too low to sustain bodily functions.
The Science Behind Hypoglycemia
Insulin sensitivity plays a crucial role in regulating blood sugar levels. Insulin resistance occurs when cells become less responsive to insulin, leading to elevated blood sugar. Over time, this can lead to hypoglycemia if not managed properly.
During periods of physical activity or after consuming meals containing simple sugars, the body's demand for glucose increases rapidly. If dietary carbohydrates aren't balanced with protein and healthy fats, a rapid spike in blood sugar often follows. To avoid severe episodes of low blood sugar, diabetics must prioritize an even carbohydrate-to-protein ratio throughout their diet.
Blood Sugar Ranges: What Levels Are Considered Dangerously Low?
In general terms for adults without diabetes, the American Diabetes Association recommends the following normal fasting glucose levels:
- Fasting plasma glucose (FPG): 70–99 mg/dL A postprandial blood sugar of less than 140 mg/dl is also considered within a safe range. These numbers can vary among different sources; consult your healthcare provider for personalized guidelines.
Symptoms and Risks Associated with Low Blood Sugar
Common symptoms include:
- Shakiness or tremors
- Sweating, nausea, and dizziness
- Headaches Other complications associated with recurrent hypoglycemia in diabetes management are more severe health problems including damage to the brain's memory centers. These can lead to lasting consequences if not managed.
Managing Hypoglycemic Episodes
When an episode of low blood sugar occurs:
- Stay calm: This is crucial, as panic increases heart rate and lowers glucose levels.
- Drink a glass of juice or eat something containing simple carbohydrates: These are easily absorbed by the body to increase blood sugar rapidly
- Check your blood sugar with an appropriate device after half hour
