Medically unexplained symptoms are best characterized by

• A. Symptoms fully explained by a medical condition
• B. Conversion or somatic symptom disorders may accompany medical conditions
• C. They never involve distress
• D. They are always due to malingering

Answer: (B)

Medically unexplained symptoms reflect situations where physical complaints either lack a full medical explanation after evaluation or occur in the context of functional disorders that affect how symptoms are perceived and experienced. The best choice captures that these symptoms can coexist with medical illnesses and may be part of conversion or somatic symptom disorders. In other words, a patient can have a genuine medical condition and also experience symptoms that are better explained by a functional or psychological process (SSD or conversion), often with distress or impairment. This differs from the other options: symptoms aren’t always fully explained by a medical condition, they commonly involve distress, and they are not typically due to deliberate faking (malingering).
