In a nutshell
This study aimed to investigate the link between salt intake and nocturia. This study found that reducing salt intake had beneficial effects on nocturia symptoms.
Nocturia is the urge to urinate at night. Reducing the amount of salt in the diet could reduce nocturia. It is unclear what effect salt reduction has on nocturia.
Methods & findings
This study included 321 patients. 223 patients were successful in reducing their daily salt intake (S group), whereas 98 patients failed to reduce their salt intake (F group). Patients were interviewed to assess their nocturia. Men had less than 8 g/day and women had 7 g/day of salt.
The patients in the S group reported less urinary frequency and nocturia. They reported a better quality of life. The patients in the F group did not report any improvement during this study.
The bottom line
This study found that reducing salt intake improves nocturia. The authors suggested that patients with nocturia who also have high salt intake should be advised to reduce their salt intake.
The fine print
The number of patients included was quite small. Further larger studies are needed for better evidence.
