To help ease the effects of nocturia and depending on the source for you, a simple lifestyle change may be to drink less fluids before bedtime or wear compression stockings and prop your legs up during the day to reduce swelling and fluid accumulation in the legs.
Some medicines can help decrease the production of urine at night or help with an overactive bladder, but keep in mind that many of these medications can have undesirable side effects. Sometimes, treating other health problems like BPH, diabetes, sleep apnea, or an enlarged prostate can also make nocturia better.
