A disorder characterized by impaired bodily functions without detectable organic disease; used particularly in neurology, gastroenterology, and psychiatry to describe conditions like irritable bowel syndrome or functional neurological disorder.

FAQ
Frequently Asked Questions
Yes, it is a recognized medical condition where patients experience genuine and often debilitating symptoms, despite the absence of detectable structural damage.
While psychological factors can play a role, a functional disease is categorized as a physical health condition affecting specific bodily systems (e.g., digestive, nervous). It is not classified as a primary psychiatric disorder.
Treatment is often multidisciplinary, focusing on managing symptoms and improving function. It may include dietary changes, physical therapy, cognitive-behavioral therapy, and medications for symptom relief.
Many functional diseases are chronic, meaning long-term management is needed. Symptoms can often be significantly improved or controlled, leading to a good quality of life, but a definitive 'cure' in the traditional sense is less common.
