Background: Thirst is an underreported and under evaluated symptom in clinical practice. Like pain, it is often a neglected symptom which the clinician should properly enquire in history taking. The reason for undertaking this study is to throw light on the prevalence of sudden unquenchable thirst in patients admitted with acute febrile illness. Surprisingly no similar study was done in fever patients. The aims and objectives of the study are to study the prevalence of clinical symptoms in acute febrile illness, to study the prevalence of thirst in patients with normal blood pressure and in shock, to study the prevalence of hyperdipsia in dengue patients, to correlate the onset of hyperdipsia with prolongation of capillary refill time and increase in hematocrit. Materials and methods: 200 patients admitted in the fever unit of Tirunelveli medical college during the epidemic from august 2017 to January 2018 were studied. This study is a prospective observational study. Results: Hyperdipsia was present in 64% of fever cases. 42.18% of hyperdipsia patients were in shock. Excess thirst was prevalent even in patients with normal blood pressure (p<0.001), which suggests that onset of thirst preceded development of shock. 85.4%of dengue patients had hyperdipsia (p<0.001).The correlation of thirst with prolonged capillary refill time and increased hematocrit we're also statistically significant. Conclusion: Hyperdipsia is a valuable symptom as its onset precedes Hemodynamic and hematologic abnormalities in fever patients and guides the clinician in appropriate management.
Keywords: Hyperdipsia, shock, haematocrit.
