Waking up to go to the bathroom at night: why it happens and when to be concerned

More than half of men and women over 60 years old get up at least once per night to go to the bathroom, according to the National Institutes of Health (NIH), and a significant proportion of them do this more than twice. For a large part of them, this nocturnal habit has become naturalized as inevitable at a certain age. However, urologists cited by the magazine Parade warn that it is not always a normal aging process: in several cases, nocturia—the medical term for the need to urinate during the night—can be the first visible sign of an underlying disease that has not yet been diagnosed. With the passage of time, the body undergoes a series of modifications that collectively make nighttime bathroom visits more frequent. The brain, explains Dr. Justin Houman, a urologist specializing in men's health, produces a smaller amount of antidiuretic hormone over the years, which is responsible for slowing down urine production while sleeping. As a result, the kidneys work more actively during the night and produce a greater volume of urine. PUBLICITY This is added to the fact that the bladder loses elasticity with age and becomes more reactive to small amounts of liquid. Another contributing factor is the accumulation of fluids in the legs during the day: when lying down, that fluid returns to the circulatory system and is processed by the kidneys, which increases nocturnal urine production. Dr. Lawrence Dagrosa, a urologist at Dartmouth Health in New Hampshire, adds another variable: sleep quality deteriorates with age, and this makes any stimulus—including a slight urge to urinate—sufficient to wake a person who would have previously slept without interruption. PUBLICITY When nocturia hides another disease When nocturia intensifies or appears suddenly, specialists recommend ruling out specific medical conditions before attributing it simply to the passage of time. In men, one of the most common factors is prostate enlargement. As this gland grows, it exerts pressure on the urethra and prevents the bladder from emptying completely, causing it to refill in a short time. Houman points out that those who suffer from it usually notice a weak stream of urine, difficulty starting urination, or the persistent feeling that the bladder is not fully emptied. PUBLICITY Diabetes is another frequent cause. According to the Endocrine Society, it is estimated that 1 in 3 adults over 65 have diabetes, and the condition can alter urinary function through different pathways: excess glucose in the blood increases the concentration of sugar in the urine, which irritates the bladder; furthermore, it triggers thirst and, with it, the consumption of fluids. Dagrosa warns that, in more advanced stages, the disease can damage the nerves that regulate the bladder and significantly aggravate the problem. Beyond the prostate and diabetes, there is a group of conditions that are frequently linked to nocturia without the patient suspecting it. Sleep apnea, heart failure, kidney disease, overactive bladder, and urinary infections are among the most common. Neurological conditions such as Parkinson's or the sequelae of a stroke, hormonal changes associated with menopause in women, and certain everyday medications are also included. PUBLICITY When to see a doctor Both Houman and Dagrosa agree that waking up up to once per night can be considered within the expected margins for an older adult. The threshold that justifies a medical consultation is exceeding two nocturnal interruptions habitually, the change occurring suddenly, or the fragmentation of sleep affecting rest and quality of life. Houman lists signs that require more urgent attention: blood in the urine, burning or pain during urination, weak stream, excessive thirst, weight loss without apparent cause, swelling in the legs, difficulty breathing, and loud snoring accompanied by daytime fatigue. The total inability to urinate, he emphasizes, constitutes a medical emergency. PUBLICITY Habits to reduce nocturnal interruptions For those for whom nocturia is due to aging and not a disease, there are specific adjustments that can reduce nighttime interruptions. Dagrosa recommends limiting fluid intake starting from 6:00 PM, and reducing the consumption of spicy or acidic foods, as the bladder's sensitivity to these stimuli increases with age. Caffeine and alcohol deserve special mention: in addition to directly irritating the bladder, they alter sleep architecture, and their combined effect becomes more pronounced in older people. “Once we identify the cause, the problem usually has a solution,” Houman stated. Specialists insist that nocturia is not a condition that should be assumed as an inevitable part of aging, and that those who suffer from it have concrete reasons to seek medical help.
