Which of the following are signs of hypoglycemia?

• A. Weight gain and fatigue
• B. Sweating, clammy, confusion, light headedness, double vision, tremors
• C. Headache only
• D. Nausea and vomiting

Answer: (B)

Recognizing hypoglycemia comes from noticing a mix of autonomic and brain-related symptoms. The autonomic signs arise as the body releases adrenaline to raise blood sugar, leading to sweating, clammy skin, and sometimes tremors. When the brain doesn’t get enough glucose, you can see neuroglycopenic symptoms like confusion, feeling light-headed, and visual disturbances such as double vision. The combination of sweating or clamminess with confusion, light-headedness, double vision, and tremors is characteristic of low blood sugar, which is why that set of signs is the best answer. Other options don’t fit as well because weight gain and fatigue aren’t classic early indicators of hypoglycemia, a headache by itself is nonspecific, and nausea and vomiting can occur with many conditions and aren’t the defining signs of a low glucose state. If hypoglycemia is suspected, check blood glucose and treat with a fast-acting carbohydrate while monitoring the person closely and seeking further care if needed.
