    Abstract:
    The article presents an evaluation of the state of the digestive system in astronauts during short-term and long-term space flights. After short-term (7- or 8-day) flights, there was a transitory activation of gastrointestinal enzyme systems. After prolonged space flights, there was an increase in gastric acidity and pepsin excretion, as well as pancreatic and intestinal malfunctions. In summary, there is a transition of the digestive system to a new level of functioning.
