Why am I always tired? 22 medical reasons for feeling tired

Somatization Disorder

A person with somatization disorder is preoccupied with numerous “somatic” (physical) symptoms. The symptoms often cause significant distress and interfere with daily life. However,  the person’s complaints cannot be explained by an underlying medical disorder. Patients with somatization disorders often complain of pain or fatigue. Symptoms are often of gastrointestinal nature, such as nausea, bloating, and diarrhea. Erectile dysfunction is a common complaint in men. Women may experience menstrual irregularities. Neurological symptoms such as impaired coordination, difficulty swallowing, loss of touch or pain sensation, and double vision are often present.
