While fatigue is seen with a prevalence of 7-8% in the normal population, it is more prevalent in Primary Sjögren's syndrome (PSS). In the studies conducted so far, the frequency of fatigue was seen at a frequency of over 30% in Primary Sjögren's syndrome. Although fatigue is so common in PSS, there is not enough data about the conditions in which fatigue develops in PSS. Other common conditions in PSS, apart from fatigue, are psychometric disorders such as common pain, depression and anxiety, and sleep disorders. In the studies conducted so far, each situation mentioned is common in PSS and seems to be related to each other. In the literature, there is no data on how many psychometric parameters, pain level, and insomnia affect fatigue and which are independent risk factors in PSS.
Fatigue is a common clinical finding in Primary Sjögren's syndrome (PSS). In PSS, there is not enough data about the conditions in which fatigue develops and which clinical conditions the disease is associated with. This study was aimed to determine the level of fatigue in Primary Sjögren syndrome and to investigate the factors affecting the level of fatigue.
