Abstract
The study found out the dependence of the manifestation of symptoms of chronic non-communicable diseases of the digestive system on the duration of a person’s own unit of time. It was identified that individual age points of exacerbations of chronic non-communicable diseases of the gastrointestinal tract are consistent with the duration of the individual’s own biological cycle. Method. In each patient examined by the chronometric test method the “ τ type” was determined, for which the classical method of reproducing intervals with a duration of tQ = 2, 3, 4, 5 c was used, which were set by the experimenter and reproduced by the surveyed using an electronic chronoscope with an accuracy of 0.001 c. Results. It was identified that individual age points of exacerbations of chronic non-communicable diseases of the gastrointestinal tract are consistent with the duration of the individual’s own biological cycle.
