Thus, as stated above, the NUV measurement omits the last void before going to bed, but includes the first morning void if the urge to pass urine awoke the patient.Frequent Urination at Night and Slow Urine Stream at Night in Men: Symptoms of Enlarged Prostate The International Continence Society (ICS) defines NUV as “ the total volume of urine passed from the time the person goes to bed with the intention of sleeping and the time of waking with the intention of rising.” The first morning void should be included in the nocturnal urinary volume (NUV). The volume of fluid intake and time of intake should also be recorded.īased on information recorded in the diary, a physician can identify whether the patient is having polyuria, nocturnal polyuria, or bladder storage problems. Timing of voids, number of emptyings, and volume of urine voided at day and night should be recorded in the diary. The principal diagnostic tool for nocturia is the voiding bladder diary. Increased airway resistance in obstructive sleep apneaĪ detailed history of the problem is necessary to establish what is normal for the patient and setting the baseline.Consuming water rich foods at night (fruits, vegetables, rice, pasta, salads).(In liver, kidney and heart disease, the person has swollen feet and ankles during the day due to fluid accumulation (by gravitation on standing), but on lying down this fluid passes into the bloodstream and is excreted by the kidneys resulting in nocturnal polyuria.) Other reasons for nocturnal polyuria include the following conditions. Nocturnal polyuria is due to hormonal imbalances and patients with NPS have low levels of arginine vasopressin (AVP). What are the Causes of Nocturnal Polyuria? Nocturia occurs equally among both sexes, but the incidence is higher in younger women compared to younger men and in older men compared to older women. The incidence rises in persons above the age of 80 years. More than 50 percent of men and women over the age of 60 have been found to have nocturia in many communities. Statistics show that 5-15% of people between 20-50 years, 20-30% of people between 50–70 years, and 10-50% of people older than 70 years old urinate at least twice a night. The third condition is a bladder problem. The first two conditions are associated with abnormal levels of arginine vasopressin (AVP) or atrial natriuretic hormone (ANH). Bladder storage disorders that decrease the bladder capacity – enlarged prostate, neurogenic bladder, drugs, anxiety.The total 24 hour urine output therefore remains normal. Nocturnal polyuria – Urine output increases at night with proportional decrease in daytime urine output.Global polyuria – Urine output increases throughout the day, and the total 24 hour urine output exceeds 40 ml/kg body weight.Nocturia has a total of four major underlying causes. It is one of the underlying causes of nocturia, which is defined as the increased passage of urine during night, waking the patient up from sleep. Persons with NPi greater than 35 percent are said to have nocturnal polyuria. the nocturnal urine output as a percentage of the 24-hour urine output. It is important to remember that persons with nocturnal polyuria syndrome have normal 24 hour urinary output not exceeding 40 ml/kg body weight.Ī measurement devised to standardize the clinical diagnosis of nocturnal polyuria syndrome is the nocturnal polyuria index (NPi) i.e.
