Infection or Illness: Illnesses can raise blood glucose levels.
Stress: Physical or emotional stress can affect blood glucose control.
Inactivity: Lack of physical activity can reduce insulin sensitivity.

Symptoms of Hyperglycemia

Increased thirst
Frequent urination
Blurred vision
Fatigue
Headache

How to Correct Hyperglycemia

Check Your Blood Glucose: Confirm that your blood glucose level is indeed high.
Take Corrective Insulin Dose: If you take insulin, administer a correction dose as directed by your healthcare provider.
Drink Water: Stay hydrated by drinking plenty of water to help flush out excess glucose.
Exercise Lightly: Engage in gentle physical activity, such as walking, to help lower your blood glucose level.
Monitor Regularly: Recheck your blood glucose level every few hours until it returns to your target range.
Contact Your Healthcare Provider: If your blood glucose levels remain high despite your efforts, contact your healthcare provider for further guidance.

Understanding Low Blood Glucose (Hypoglycemia)

Hypoglycemia occurs when your blood glucose level is below your target range, typically below 70 mg/dL (3.9 mmol/L). This can be a dangerous condition if not treated promptly. Common causes of hypoglycemia include:

Excessive Insulin Dose: Taking too much insulin.
Missed Meals: Skipping or delaying meals.
Intense Exercise: Engaging in strenuous physical activity without adequate carbohydrate intake.
Alcohol Consumption: Drinking alcohol, especially on an empty stomach.

Symptoms of Hypoglycemia

Shakiness
Sweating
Dizziness
Confusion
Irritability
Hunger
Rapid heartbeat
Blurred vision
Seizures (in severe cases)
Loss of consciousness (in severe cases)

How to Treat Hypoglycemia

Follow the 15-15 rule:

Check Your Blood Glucose: Confirm that your blood glucose level is low.
Consume 15 Grams of Fast-Acting Carbohydrates: Examples include:
- 4 ounces (120 ml) of juice or regular soda
- 1 tablespoon of honey or syrup
- 3-4 glucose tablets
- Glucose gel
Wait 15 Minutes: Allow the carbohydrates to raise your blood glucose level.
Recheck Your Blood Glucose: After 15 minutes, recheck your blood glucose level. If it is still below 70 mg/dL (3.9 mmol/L), repeat steps 2 and 3.
Eat a Meal or Snack: Once your blood glucose level is back in your target range, eat a meal or snack containing protein and complex carbohydrates to prevent another drop.
Emergency Measures: If someone is unconscious or unable to swallow, administer glucagon if available, and call emergency services immediately.
