If a person complains of a wide variety of physical symptoms over time in the absence of a physical basis for the symptoms, the diagnosis would likely be:

A) conversion disorder.
B) somatic symptom disorder.
C) body dysmorphic disorder.
D) psychophysiological disorder.

Somatic symptom disorder is characterized by an individual experiencing significant focus on physical symptoms, such as pain or fatigue, that results in major distress and/or problems functioning. The individual has excessive thoughts, feelings, or behaviors related to the physical symptoms, even though medical tests do not always find a clear cause for the symptoms. This diagnosis fits the description of a person complaining of a wide variety of physical symptoms over time without a physical basis for these symptoms.
