Good bladder health is essential to preventing urinary tract infections, the second most common type of infection in the body, according to MedlinePlus. Preventing infections may help you avoid a trip to the doctor and painful symptoms as well. If you already have an infection, it is important to seek medical attention to avoid complications such as kidney infections.
Drink plenty of water -- at least eight servings -- rather than coffee, soda pop or other caffeinated beverages, which can irritate the bladder. Water dilutes the urine and allows bacteria to be flushed from the bladder, according to Mayoclinic.com.
Take a cranberry supplement or drink cranberry juice. Experts once believed that cranberry helped make urine more acidic, though modern theories suggest that chemicals in cranberries keep bacteria from sticking to the cells that line the bladder and urinary tract. MedlinePlus reports that encapsulated formulations are generally taken in doses of 300 to 400 mg twice daily for 12 weeks. In liquid form, ideal dosages are undetermined, though one to 10 oz. daily has been used.
Empty your bladder by urinating often and whenever the urge arises. Resist holding urine, which can cause bacteria to form in the bladder and may lead to urinary tract infections.
Avoid smoking. The Kidney and Urologic Diseases Clearinghouse reports that one of the best things a smoker can do for his bladder is to quit smoking. Smoking significantly increases the risks of bladder cancer. In fact, Medline Plus says that 50 percent of all bladder cancers in men and 30 percent in women may be caused by cigarette smoke.
