What symptom is commonly experienced during abrupt nicotine withdrawal within the first 24 hours?

• A. Bradycardia
• B. Increased appetite
• C. Aggression
• D. Fatigue

Answer: (B)

Increased appetite is a common symptom experienced during abrupt nicotine withdrawal within the first 24 hours. This occurs because nicotine affects the body's metabolism and appetite regulation. When a person suddenly stops using nicotine, the body undergoes a variety of physiological and psychological changes. Nicotine normally suppresses appetite, so its withdrawal can lead to an increase in hunger and cravings for food, particularly high-calorie foods, as the body adjusts to the absence of nicotine.

The other symptoms associated with nicotine withdrawal include irritability, anxiety, and difficulties with concentration, but the increase in appetite is particularly notable within the first day as the body reacts to the loss of nicotine's appetite-suppressing effects.
