Cystitis is an inflammation of the bladder, often caused by a bacterial infection. It can lead to symptoms such as frequent urination, a burning sensation during urination, and lower abdominal pain. While it can affect anyone, it is more common in women due to their shorter urethra. Treatment typically involves antibiotics to clear the infection. Drinking plenty of fluids can help flush out bacteria. In some cases, cystitis can also be caused by irritants like certain soaps or hygiene products, making it important to identify and avoid these triggers for prevention.
