Which symptom is common in hypoglycemia (insulin shock)?

• A. Excessive perspiration
• B. Speech disturbances
• C. Double vision
• D. Feeling faint and shaky

Answer: (D)

When blood glucose drops, the brain and body react to the shortage of fuel. The most common early sign in someone with hypoglycemia is feeling faint and shaky: the body releases adrenaline, which causes tremors, a sense of instability, and lightheadedness. This combination is a classic, reliable cue that glucose levels are too low and needs rapid correction with fast-acting carbohydrates. Other signs like sweating, speech changes, or vision issues can occur as glucose falls, but the sensation of shakiness with faintness is the most typical and recognizable symptom guiding quick action.
