Early warning signs of bladder problems are linked to changes in bladder habits such as an increased urge to urinate, difficulty or pain during urination, or having blood in the urine. These problems may be linked to bladder or prostate cancer, according to Everyday Health.
An enlarged prostate, nerve damage and bladder infections are common causes of changes in bladder habits as well, cites Healthline. Early signs of more severe bladder problems include an inability to urinate, pelvic or rectal pain, unintended weight loss, or swelling in the feet and lower legs. It's recommended that one visit a health care professional if experiencing these symptoms.
