Which of the following is a potential effect of anorexia?

• A. Fatigue
• B. Brain damage
• C. Hair growth
• D. Increased appetite

Answer: (A)

When someone isn’t getting enough calories and nutrients, the body doesn’t have the fuel it needs for daily activities. That energy shortfall shows up as fatigue—feeling unusually tired and weak because energy production in the body slows and muscles don’t have enough fuel to work well. Over time, longer-term malnutrition can affect multiple systems, but fatigue is the most common early effect. Hair changes can occur with nutrient deficiencies (often thinning or hair loss), not new hair growth, and appetite tends to be reduced rather than increased.
