      Frequently getting up to go to the bathroom at night not only affects sleep quality, but may also indicate physical problems in the long run. Many people worry about "kidney deficiency" when they think of excessive nocturia. In fact, the reasons are far more than this. With age, changes in lifestyle habits, and even in the early stages of the disease, increased nocturia may occur. So, what is the cause of excessive nocturia? How do we tell if we need medical attention?

    What are the causes of excessive nocturia?

      1. Physiological factors

      Drinking too much water before going to bed, or consuming diuretic foods such as coffee, strong tea, alcoholic drinks, and watermelon will increase the excretion burden on the kidneys and lead to increased urination at night. This situation usually improves quickly after adjusting the diet before going to bed. It is a temporary phenomenon and there is no need to worry too much.

      2. Urinary system diseases

      Diseases such as prostatic hyperplasia, cystitis, and urinary tract infections can irritate the bladder mucosa or compress the urethra, resulting in reduced bladder capacity, frequent urination and urgency, and symptoms that are more obvious at night. It is often accompanied by symptoms such as incomplete urination and painful urination, and needs to be diagnosed through routine urine examination, urinary tract ultrasound and other examinations.

      3. Endocrine and metabolic issues

      When the blood sugar of diabetic patients is too high, the kidneys cannot completely reabsorb glucose, and the urine osmotic pressure increases and takes away a large amount of water.; Patients with diabetes insipidus who lack antidiuretic hormone may also experience increased nocturia. Diabetic patients may also experience symptoms such as polydipsia, polyphagia, and weight loss.

      4. Effects of drugs

      Taking diuretics (such as hydrochlorothiazide), some antihypertensive drugs, or psychotropic drugs will directly promote urine excretion, leading to increased nocturia. If you are taking this type of medicine and have obvious nocturia symptoms, you can consult your doctor whether you need to adjust the medication time or dosage.

      5. Age and organ function decline

      The concentrating function of the kidneys in middle-aged and elderly people decreases, and the urine produced at night cannot be effectively concentrated. The detrusor function of the bladder is weakened, and the urine storage capacity is reduced, making frequent nocturia prone to occur. It usually manifests as urination more than 2 times at night without other discomfort, which is a common manifestation of physiological decline.

    How to deal with excessive nocturia

      1. Adjust living and eating habits

      Reduce the amount of water you drink 2-3 hours before going to bed, and avoid coffee, strong tea, alcohol and high-hydration foods.; Eat a light dinner with less salt to reduce the metabolic burden on the kidneys. Develop the habit of emptying your bladder before going to bed, avoid excessive wakefulness when getting up at night, reduce interference with sleep, and observe whether symptoms improve.

      2. Treatment of basic diseases

      If you are diagnosed with a urinary tract infection, you will need to take antibiotics as directed by your doctor.; Patients with prostatic hyperplasia can use drugs such as α-blockers, and if necessary, undergo surgical treatment. ; Diabetic patients need to strictly control blood sugar and reduce the impact of high blood sugar on urination through medication, diet and exercise.

      3. Optimize medication and symptomatic care

      If you suspect that frequent nocturia is related to medications, inform your doctor promptly and adjust the medication regimen under guidance to avoid discontinuing the medication on your own. Middle-aged and elderly people can use bedside urinals to reduce the risk of falling at night, and wash the perineum with warm water before going to bed to prevent infection. ; If symptoms persist, further examination is needed to check for hidden diseases.

      If you only occasionally urinate 1-2 times at night and have no other discomfort, it is mostly related to your living habits. It can be improved by reducing drinking water at night and avoiding irritating drinks. However, if you urinate ≥ 2 times at night for many consecutive days and are accompanied by symptoms such as thirst, fatigue, edema, and painful urination, you should seek medical treatment in time to check for problems such as diabetes, kidney disease, or prostate. Early detection and early intervention can protect the body's "drainage system".
