Nocturia with a grain of salt

What is Nocturia

Nocturia is a type of sleep disruption triggered by the need to urinate much time throughout the night. Nocturia is a chronic medical condition that affects mostly people over 50. This medical condition affects both men and women in a similar proportion, though the cause of the problem often differs greatly between sexes.

The disruption of healthy sleep patterns that results from nocturia can significantly affect a person’s quality of life. These repeated and unavoidable disruptions can have a significant impact on the individual’s health and well-being. In short, nocturia is not a problem to be taken lightly, and certainly not with a grain of salt.


Nocturia can simply be the result of a high level of fluid intake. It can also be the result of a bladder or prostate condition, the side effect of drugs such as lithium or diuretics, an excess of vitamin D in the system, a sleeping disorder such as sleep apnea, or even untreated diabetes. In all cases, the individual affected should consult with a health professional, as self-diagnostics can be misleading and lead to even bigger problems.

The Study

A recent study conducted by a team of Japanese scientists suggest that in many cases, regardless of the medical cause of nocturia, reducing the amount of salt in a person’s diet can be beneficial. It should be noted that the said study excluded functional abnormalities affecting urination — such as a neurogenic bladder. The subjects of the study who adhered to a regimen that reduced their salt intake also reduced the number of nocturia occurrences by over 50% — from 2.3 to 1.4 — on average.

The results of the study, which have not been published yet, were announced during the 32nd Annual EAU Congress. The authors concluded that reducing the overall salt intake can be beneficial, especially for those who suffer from nocturia and have responded poorly to medication.
