How does one tell if someone is having a hypo or hyper?

To determine if someone is experiencing hypoglycemia (low blood sugar) or hyperglycemia (high blood sugar), observe their symptoms. Hypoglycemia may present with shakiness, sweating, confusion, irritability, or dizziness, while hyperglycemia can cause increased thirst, frequent urination, fatigue, and blurred vision. Additionally, checking blood glucose levels with a glucose meter can provide a definitive diagnosis. If in doubt, it’s important to seek medical assistance.
