You're sleeping soundly and dreaming in the middle of the night, and suddenly your brain signals that you want to urinate. So you forcibly suppressed the desire to urinate, but in the end you were defeated by the urge to urinate and had to get up conveniently. Presumably, many people have had such an experience!
In fact, in most cases, people sleep all night and urinate very little. This is because after we go to sleep, the speed of the body's various organs has slowed down, coupled with the impact of no hydration, sweating and breathing all night, so a healthy adult, the number of times to urinate all night is only between 0-2 times.
If the number of urinations increases at night, in most cases, it is related to drinking too much water and eating a lot of watery foods that day, which does not require excessive tension at all.
However, if there are recent frequent symptoms of increased frequency of nocturia, or even more than 3-5 times of urination at night, which seriously affects the quality of sleep, this may be a manifestation of the arrival of the disease.
For example, after the following diseases find themselves, the frequency of urination will increase:
1, kidney disease: the production and discharge of urine, mainly rely on two organs, they are the kidneys and bladder. The basic function of the kidneys is to filter blood, generate urine, and remove excess metabolic waste and toxic substances from the body through urine.
After the appearance of kidney disease, glomerular filtration and tubular reabsorption may be impaired, resulting in a large number of formation of primary urine, but the renal tubules cannot concentrate the original urine, so the number of patients' nocturia increases;
2. Do not ignore diabetes: the typical symptom of diabetes is an increase in blood glucose, when the glycemic index exceeds the normal value of renal glucose threshold, the glucose filtered out by the glomeruli cannot be completely reabsorbed by the renal tubules, and the solute concentration of the renal tubules is increased.
Under the influence of osmosis, part of the water is also retained in the renal tubules, and the water reabsorption is reduced, and eventually it develops into osmotic diuresis.
Usually, the higher the blood sugar, the more urine sugar will be excreted, and the amount of urine will naturally increase. Relevant research surveys show that the total urine output of diabetic patients can reach about 5000-10000ml in 24 hours;
3. Heart disease: there are many types of nocturia increase, one of which is "drainal nocturia increase", which is common in patients with heart disease with cardiac insufficiency, due to impaired heart function, it is easy to develop water retention in the body.
When lying flat at night and there is no activity, the amount of blood returning to the heart is significantly increased compared with the daytime, and the renal blood flow will also increase, and nocturia will naturally increase. At the same time, patients may also have symptoms such as supine edema, fatigue and fatigue, and dyspnea;
4, prostate disease: the focus here is prostatic hyperplasia, which is common in men over 50 years old, and is also the most high incidence of male geriatric disease.
When prostatic hyperplasia occurs, affected by urinary tract compression, the number of nocturia increases when the patient lies flat. At the same time, patients may also be accompanied by symptoms such as urinary frequency and urgency, urinary incontinence, and weakness of urination;
5. Bladder disease: Clinically, there are three types of cystitis that can cause increased nocturia, the most common of which is bacterial cystitis.
In addition to increased nocturia, patients may also be accompanied by symptoms such as frequent urination, decreased urination, dysuria, and tenesmus.
All in all, there are many reasons for the increase in the number of urinations at night, but in most cases, frequent nocturnal urination is related to the amount of water consumed that day. If the frequent symptoms of nocturia appear at the same time, accompanied by multiple other physical discomforts, or if the increase in nocturia lasts for more than 1 week, this may be a signal of the arrival of the disease, and it is necessary to seek medical attention in time for relevant examinations.
