What causes frequent urination at night during sleep?

Excessive urination at night may be caused by factors such as aging, negative emotions, cystitis, diabetes, and nephritis. It is recommended to seek timely medical attention, identify the underlying cause, and receive symptomatic treatment under a doctor's guidance. Specific analysis is as follows:

1. Age-related factors: With advancing age, kidney function may decline, and the renal tubules' ability to reabsorb water may weaken, potentially leading to increased nighttime urine volume. It is advisable to moderately control fluid intake before bedtime and ensure sufficient sleep. If discomfort worsens, prompt medical consultation is recommended.

2. Negative emotions: Prolonged negative mental states, such as anxiety or stress, may lead to urinary system abnormalities, resulting in increased nocturnal urination and possibly accompanied by reduced sleep quality. It is recommended to adjust one’s mindset promptly and maintain a relaxed, positive mood.

3. Cystitis: This may be related to bacterial invasion of the urinary tract or weakened immunity. When pathogens invade the bladder, they may affect the bladder mucosa, causing increased nighttime urination, and possibly symptoms such as urgency and pain during urination. Patients are advised to follow medical instructions for treatment with medications such as cefadroxil granules, amoxicillin granules, or erythromycin tablets.

4. Diabetes: This may be associated with insufficient insulin secretion, genetic factors, and others. Persistent high blood glucose levels can damage kidney tissue, leading to abnormal urination and increased nocturnal urine output, often accompanied by symptoms such as increased appetite and frequent urination. During treatment, it is important to control blood sugar levels as directed by a physician, along with dietary adjustments and regular exercise. Additionally, medications such as insulin degludec injection, orlistat capsules, and acarbose capsules may be used as prescribed to support treatment.

5. Nephritis: Various factors such as chronic sleep deprivation and pathogen infection may lead to structural and functional abnormalities in the kidneys, resulting in increased nighttime urination, possibly accompanied by edema. It is recommended to take medications such as Yishen Huashi Granules, Nephritis Relief Tablets, or Yishen Kang Capsules as prescribed to help alleviate physical discomfort.

In daily life, it is advisable to reduce fluid intake before bedtime to prevent excessive nighttime urination due to high fluid volume. Emptying the bladder before sleep may also help minimize nighttime bathroom trips and improve sleep quality. Additionally, maintaining adequate sleep duration and reducing mental stress are beneficial for overall health.
