Objective: To examine the prevalence of comorbid conditions in patients diagnosed with fibromyalgia. Methods: The retrospective cross-sectional study was conducted at Eskisehir Osmangazi University, Eskisehir, Turkey, and comprised data of fibromyalgia patients aged 18 years or more admitted between January 1, 2012 and August 15, 2016. Hospital's database was investigated using the International Classification of Diseases, 10th Revision codes to identify fibromyalgia cases and predetermined comorbid conditions. SPSS 21 was used for data analysis. Results: Of 509 patients, 51(10%) were males and 458(90%) were females with an overall mean age of 50.24 +/- 12.32 years. Of the total, 345(67.8%) patients had at least one comorbid disease, while 164(32.2%) had no comorbid disease. The most prevalent condition was cardiovascular diseases in 187(36.7%) patients followed by endocrine diseases in 157(30.8%). Conclusion: Fibromyalgia is a disease that is seen to be increasing in frequency in recent years. It is useful to evaluate fibromyalgia patients with their comorbid conditions on their follow-up.
