**Functional pathology** is a medical term that is used to describe a condition when some organs or systems in the body begin to work incorrectly or not as they should. In this condition, a person may experience a variety of symptoms, including pain, fatigue, weakness and other discomfort. Functional pathologies can occur due to various reasons, such as injuries, infections, chronic diseases, etc. Treatment of functional pathologies usually includes the use of medications, physiotherapy, massage, as well as lifestyle changes, such as proper nutrition, exercise and proper alternation of work and rest. However, there are also complex cases that require surgical intervention. If you suspect functional pathologies, you should consult a specialist for diagnosis and treatment.
