Hi dear Rose, Being incontinent is associated with dehydration especially when fluid/water intake is lower than usual. This might be a cause to dizziness (dehydration). There are many factors causing incontinence and they can be treated: - enlarged prostate - urinary tract infections - genital infections I suggest to convince him to consult an urologist and to run further tests: - abdominal ultrasound - urine analysis to find out the real culprit to the incontinence and get it treated properly. If it is difficult to send him to the doctor, then, ask him to: - get some bladder training - do some Kegel s exercise - schedule together when to go to the bathroom - limit/avoid coffee, energetic drinks or citrus fruit - avoid taking fluids in the afternoon - keep good hygiene of his genitalia and pelvic floor Hope it helped!
