Concept Analysis of Thirst as a Symptom and Its Causes From the Perspective of Iranian Traditional Medicine: A Hybrid Model Study

Abstract

Objective: Thirst (Attash) is a diagnostic sign of diseases from the perspective of Iranian Traditional Medicine (ITM).The purpose of this study is to provide a functional definition for the concept of thirst and its causes in ITM. Methods: In this study, we used the concept analysis (hybrid model) which has three phases; in the theoretical phase, the content related to the definition of thirst and its causes were searched in ITM books and an efficient definition of thirst was presented. In the fieldwork phase, main themes were obtained after semi-structured interviewing of 16 ITM specialists. In the final (analytical) phase, the results of the two previous phases were compared to each other to present the final definition for thirst. Results: The thirst is defined as the need for water and any food that is cold and wet, and the increase and decrease in thirst is a sign of disease. For its examination, it is necessary to pay attention to the change in the degree of thirst and the amount of consumed water or cold/wet foods. It is important to differentiate between drinking water as recommended, drinking water as habit, or drinking water because of dry mouth with thirst. Different characteristics of thirst can be used to diagnose the affected organs. Conclusion: In this study, using the concept analysis method, a functional definition of the thirst as a symptom was presented and its causes were investigated. The low number of studies on thirst and lack of access to some ITM specialists were some of the limitations of our study. It is recommended to investigate the prevalence of thirst in patients and its relationship with dystemperament in future studies.
