Hypoglycemia is generally defined as a blood glucose level of less than 70 mg/dL (3.9 mmol/L).
However, the specific symptoms and severity of hypoglycemia can vary based on the individual and the degree to which the blood glucose level falls.
Thresholds for Hypoglycemia:
- Mild Hypoglycemia: Blood glucose between 60–70 mg/dL (3.3–3.9 mmol/L). At this level, symptoms like shakiness, sweating, and hunger may occur.
- Moderate Hypoglycemia: Blood glucose between 50–59 mg/dL (2.8–3.3 mmol/L). Symptoms may become more pronounced, including confusion or irritability.
- Severe Hypoglycemia: Blood glucose below 50 mg/dL (2.8 mmol/L). This may result in dangerous symptoms, such as seizures, loss of consciousness, and the inability to treat oneself, which requires immediate intervention.
Important Notes:
- Hypoglycemia levels may vary slightly depending on individual circumstances and the context in which the condition is being managed (e.g., for people with diabetes).
- Symptoms can also vary by individual; some people may feel symptoms at higher levels than others. Therefore, regular monitoring of blood sugar levels is important for managing and preventing hypoglycemia.
Common Symptoms of Hypoglycemia include:
- Shakiness
- Sweating
- Dizziness or lightheadedness
- Headache
- Confusion
- Irritability
- Hunger
If blood glucose levels fall too low and are not addressed quickly, it can lead to severe complications such as loss of consciousness, seizures, or even coma.
