Which symptom indicates possible hypoglycemia requiring action?

• A. Nausea and vomiting
• B. Shaking, sweating, confusion, dizziness, or rapid fatigue
• C. Hair loss
• D. Skin rash

Answer: (B)

Recognizing low blood sugar early is crucial because it can quickly impair thinking and physical ability. The signs listed—shaking and sweating along with confusion, dizziness, and rapid fatigue—show both the body’s fight-or-flight response and the brain not getting enough glucose. These combined symptoms are a strong indicator that action is needed right away: check blood glucose if you can, and give a fast-acting carbohydrate (like juice or glucose tablets) to raise the level, then recheck in about 15 minutes. The other options don’t point to hypoglycemia specifically: nausea and vomiting can come from many causes, hair loss isn’t related to low sugar, and a skin rash isn’t a typical sign of hypoglycemia. If symptoms are severe or the person can’t swallow or doesn’t improve after treatment, seek urgent help and follow the plan for administering glucagon if it’s prescribed.
