Incontinence after drinking may be caused by one-off dysfunction, or it may be caused by spinal cord injury, lumbar spinal stenosis, and other reasons such as lumbar disc herniation. 1. Transient dysfunction: After drinking alcohol, the cerebral cortex’s control of the bladder and rectum will be weakened under the effect of alcohol, which may cause involuntary contraction of the bladder and rectum, thus causing urinary and fecal incontinence. This is a transient bladder and rectal dysfunction, usually after the end of alcohol metabolism in the body will return to normal. 2. Spinal cord injury: Spinal cord injury may be caused by spinal trauma, other parts of the injury and so on. If the spinal cord injury is caused by trauma after drinking, the patient may suffer from incontinence, paralysis of the lower limbs, paraplegia and other manifestations. 3. Lumbar spinal stenosis: Lumbar spinal stenosis is considered to be caused by congenital vertebral canal underdevelopment, osteophytes, ligament hypertrophy, spinal trauma and so on. Patients will manifest as low back pain, intermittent claudication, sciatica, urinary and defecation disorders. If patients with lumbar spinal stenosis drink alcohol, they may have incontinence. 4. Other: patients with lumbar disc herniation, spinal canal tumor and other diseases can also cause incontinence after drinking. It is recommended that patients who experience incontinence after drinking need to seek medical attention in a timely manner, if it is caused by a transient dysfunction, no treatment is needed. For disease-induced incontinence, it is necessary to consult a doctor in time and follow the doctor’s instructions for treatment.
