Overactive bladder syndrome can potentially cause pain in the lower abdomen. Typical symptoms of patients with overactive bladder are urinary urgency, frequent urination, increased nocturia, and urinary incontinence, and some patients experience pain in the lower abdomen during urinary urgency. Overactive bladder syndrome is a syndrome characterized by urinary urgency, and patients are often accompanied by frequent urination and increased nocturia. The cause of the disease has not been clearly defined and may be related to factors such as the urethral muscles, the voiding center, and the sensory nerves of the bladder. Patients with overactive bladder may experience abdominal pain, which is an accompanying symptom of the disease, usually in the suprapubic or perineal area when the patient is in urgent need of urination. If there is no urgency to urinate, but there is pain in the abdomen, it may also be caused by other reasons, such as enteritis, colon tumor, cystitis and other diseases. For female patients, it may also be due to gynecological disorders, such as endometritis, salpingitis, and fibroids. Patients with overactive bladder may have pain in the lower abdomen, but this symptom cannot be used to determine that it is caused by overactive bladder. If the patient wants to make a clear diagnosis, it is recommended to go to the local regular hospital for further examination.
