Which of the following is a common symptom of hypoglycemia?

1. Nausea and vomiting

2. Increased thirst

3. Shakiness and sweating

4. Frequent urination

The correct answer is: Shakiness and sweating

Shakiness and sweating are common symptoms of hypoglycemia because they are part of the body's acute response to low blood sugar levels. When blood glucose drops, the body releases adrenaline (epinephrine) as a counter-regulatory hormone to help raise blood sugar back to normal levels. This adrenaline response triggers various physiological reactions, including shakiness, sweating, increased heart rate, and anxiety. In contrast, nausea and vomiting typically are associated with various gastrointestinal disorders or other medical conditions rather than hypoglycemia. Increased thirst is more commonly related to hyperglycemia or diabetes-related complications like dehydration. Frequent urination often occurs with high blood glucose levels, particularly in diabetic patients, rather than low blood sugar situations. This context helps clarify why shakiness and sweating are significant indicators of hypoglycemia, highlighting the importance of recognizing this response for effective diabetes management.
