Disorders that are not clearly attributable to an organic disease are called somatoform disorders. Their symptoms are called psychosomatic symptoms and include insomnia, fatigue, and weakness. These disorders can also be associated with heartburn, depression, irregular heartbeat, dizziness, pain, cardiovascular problems, gastrointestinal discomfort, erectile dysfunction, a sensation of pressure in the throat, chest problems, hallucinations, and double vision. Somatoform disorders can be an expression of untreated mental pain and life experiences, resulting from serious loss, profound personal injury, or disrespect. Such symptoms occur in almost all humans, but these disorders can have a serious effect in 4–20% of the population.
