Abstract
According to the frequency of seeking medical care, diarrhea is one of the most common complaints, being an important health problem. Acute diarrhea, as a rule, is infectious in nature, thus, the scope of diagnostics is aimed at assessing the patient's condition and clarifying the pathogen etiology. Chronic diarrhea has a diverse etiology, which poses a difficult task for the clinician to conduct differential diagnosis. Therefore, most guidelines on the relevant problem suggest the use of medical algorithms aimed at step-by-step exclusion of diseases accompanied by diarrhea: from the most common causes to the more rare ones. First of all, it is necessary to detail complaints, identify the presence of red flags, collect an epidemiological, drug and hereditary history, assess the nutrition habits, dietary preferences of the patient and their possible association with the manifestation of diarrhea. The general examination reveals signs of dehydration and malabsorption, as well as the presence of stigma of the underlying disease. Also, at the first stage, it is advisable to conduct the minimum necessary laboratory and instrumental studies. Subsequently, if there are difficulties in establishing the diagnosis, it is advised to re-assess the clinical picture and prescribe additional examination methods. Alongside this, symptomatic and pathogenetic therapy, dehydration, timely detection and correction of electrolyte disorders should be indicated for all patients with acute and chronic diarrhea at the stage of further examination and diagnosis confirmation.
