 Insulinoma is a rather rare neuroendocrine tumor, its prevalence in the general population is approximately 1 case per 250,000–1,000 000 population. Insulinoma produces an excessive amount of insulin, causing episodes of hypoglycemia. Nonspecific complaints and difficulties of topical diagnosis can lead to a delay in diagnosis, which reduces the quality of life of patients. The path from the appearance of symptoms to the diagnosis in some cases takes many years. This article presents a clinical case of a young patient with insulinoma, describes the diagnostic search from the collection of anamnesis to laboratory and topical diagnostics, as well as treatment tactics. Taking into account the peculiarities of insulinoma course and diagnosis, endocrinologists and doctors of other clinical specialties should be alert about this disease.

Key words: insulinoma, hypoglycemia, hyperinsulinism, neuroendocrine pancreatic tumor.
