Why you keep waking up to go to the bathroom

Making one or more trips to the bathroom every night is the defining characteristic of a medical condition called nocturia. It can be caused by aging, lifestyle habits, or underlying conditions such as an overactive bladder or (in men) an enlarged prostate. Treating nocturia starts with lifestyle changes such as avoiding fluids several hours before bedtime, eliminating caffeinated drinks 10 hours before bedtime, and limiting evening alcohol intake. Medications, pelvic floor exercises, injections of botulinum toxin (Botox), or nerve stimulation treatments may also help.
