Somatoform Disorders

Somatoform disorders are mental illnesses that cause bodily symptoms, including pain. The symptoms can't be traced back to any physical cause. And they are not the result of substance abuse or another mental illness.

The symptoms involve several different organs and body systems. The patient may report a combination of:

1. Pain

2. Neurologic problems

3. Gastrointestinal complaints

4. Sexual symptoms

An example of a somatoform disorder is Undifferentiated somatoform disorder
