Introduction
In general, the urge to urinate shortly after urinating while lying down is mainly caused by improper diet, abdominal exposure to cold, urinary tract infections, cystitis, benign prostatic hyperplasia, and other factors. If discomfort occurs, prompt medical attention is necessary. Cold temperatures can stimulate abnormal gastrointestinal motility, which may lead to a sensation of frequent urination. Avoid consuming overly spicy or irritating foods to reduce bladder irritation.
Under normal circumstances, the urge to urinate again shortly after urination is usually caused by improper diet, cold abdomen, urinary tract infection, cystitis, or benign prostatic hyperplasia. If discomfort occurs, timely medical attention is recommended. Specific causes are analyzed as follows:
1. Improper Diet
Drinking excessive fluids at night or consuming overly spicy and stimulating foods may increase urine production or trigger abnormal gastrointestinal motility, leading to the sensation of needing to urinate. It is recommended to drink water in moderation, maintain a light diet, and avoid excessive fluid intake or spicy foods in the evening.
2. Cold Abdomen
Cold temperatures can stimulate abnormal gastrointestinal motility, which may subsequently cause a frequent urge to urinate. Attention should be paid to staying warm, especially keeping the abdomen warm, to prevent chilling.
3. Urinary Tract Infection (UTI)
During a urinary tract infection, bacteria invade the urethra, bladder, or kidneys, triggering an inflammatory response. Inflammation leads to congestion and edema of the bladder mucosa, significantly increasing the bladder's sensitivity to urine. Even small amounts of urine can provoke a strong urge to urinate, possibly accompanied by symptoms such as painful urination or abnormal urine color. Treatment with medications such as levofloxacin tablets, azithromycin dispersible tablets, or fosfomycin trometamol powder should follow medical advice.
4. Cystitis
Cystitis is bladder inflammation caused by bacterial infection. The inflammation irritates the bladder wall, making the bladder overly sensitive and resulting in symptoms such as frequent urination and urgency, possibly accompanied by dysuria (painful urination) or incomplete voiding. Treatment under the guidance of a healthcare professional may include cefdinir dispersible tablets, amoxicillin capsules, or Yinhua Miniyanling tablets.
5. Benign Prostatic Hyperplasia (BPH)
Factors contributing to prostate enlargement include age, medical history, and lifestyle. Enlarged prostate can compress the urethra, impairing smooth urine flow. Even after urination, residual urine may remain near the urethral opening. When lying down, changes in body position may cause this residual urine to move, stimulating urethral receptors and creating the sensation of needing to urinate. This may be accompanied by symptoms such as weakened urine stream or increased nighttime urination. Medications such as finasteride tablets, tamsulosin hydrochloride sustained-release capsules, or Qianlieshutong capsules should be used according to medical instructions.
Avoid consuming excessively spicy or irritating foods to reduce stimulation of the bladder.
