Introduction: The nutricional status of hemodialysis patients is a factor of concern and a challenge for health professionals, specifically for nurses, which justifies the development of research on this issue. Objective: To evaluate the determinants of interdialytic weight gain in people on hemodialysis. Methods: Quantitative, descriptive, cross-sectional study, in a non-probabilistic convenience sample of 81 people in a regular hemodialysis program, from a private dialysis center in the district of Viseu. Results: Statistically significant correlation between water restrictions and weight gain. Participants who do not measure the amount of fluids allowed per day, who support thirst and who avoid very spicy meals tend to have a lower average weight gain. In terms of relative weight gain, there was only a statistically significant correlation with the item «Adjusts the amount of liquid you drink to the daily urine volume». Participants who adjust the amount of fluid they drink to the daily urine volume show less relative weight gain; those who consume whole foods more frequently show a greater increase in absolute weight. Negative significant correlation between the relative weight gain and the frequency of consumption of canned meat or fish, with a greater propensity to show a lower relative weight gain. Body mass index was associated with greater absolute and mean weight gain; greater waist circumference was associated with greater mean weight gain, but less relative weight gain; greater circumference of the neck circumference was associated with less relative weight gain. Conclusion: As improvement strategies, in the search for care excellence, reinforce and assess the health literacy level of the person undergoing hemodialysis. Nurses should reinforce health education teachings on adherence to water restrictions and control of intake of foods rich in sodium to prevent complications and better control interdialytic weight gain.
