At the present stage, much attention is paid to the peculiarities of the course of comorbid diseases of internal organs. It is due to the fact,that comorbidity or polymorbidity makes it difficult to determine which disease dominates the common clinical symptoms at each stage of exacerbation. During the treatment of patients with a comorbid or polymorbid course, it is very important to prevent polypharmacy, even, taking into account the general mechanisms of development, the possibility of common use of a number of drugs poses some difficulties in planning and carrying out rehabilitation measures.[1] Correct treatment tactic is possible only after a detailed study of the etiological and pathogenetic features of these diseases, taking into account in detail the mechanisms of development and interaction of these diseases on the quality and life expectancy of such patients.[2] Despite the large number of studies in pancreatology and endocrinology, the problems of prevention, diagnosis, medical correction and rehabilitation of patients with chronic pancreatitis (CP) and hypothyroidism still remain relevant, because the increase in the number of patients who suffering from these pathologies is gaining the scale of a global problem.[3, 4], References: 1.
