Detailed answer

A bladder infection, also known as a urinary tract infection (UTI), occurs when bacteria enter and multiply in the bladder. It typically causes symptoms such as frequent urination, a burning sensation during urination, and cloudy or bloody urine. On the other hand, a kidney infection, also known as pyelonephritis, is a more severe infection that occurs when bacteria travel from the bladder to the kidneys. It can cause symptoms similar to a bladder infection but may also involve more severe symptoms such as high fever, back or abdominal pain, nausea, and vomiting. If left untreated, a kidney infection can lead to serious complications. It is important to seek medical attention if you suspect a bladder or kidney infection to receive proper diagnosis and treatment.
