If you enjoy it, have a shot of sugar-free cranberry juice. Cranberry juice may aid in the battle against illness, however its efficacy is still being researched. Consume blueberries. They could have the similar effect as cranberries in terms of preventing germs from adhering to the lining of your urinary system. Have green tea with fennel seeds. This combination has been shown to reduce bacteria that cause urinary tract infections. If you take antibiotics, be sure to drink enough water during treatment so that you do not experience any pain when you pass urine. Also, be sure to drink something containing caffeine (such as coffee or tea) if you go to bed early because the activity in your body will keep you awake until the caffeine enters your bloodstream. Caffeine also begins working immediately, so if you want to stay up late without getting sleepy, you should avoid drinking anything with caffeine after 2 p.m. Eat foods high in fiber. Fiber helps move waste through your digestive system and out through your urine. So eat more fruits and vegetables to get the necessary amount. Avoid alcohol. It contains fluid that leaves your body through your urine. Avoid chemicals. Certain chemicals found in products such as toilets, laundry detergents, house paints, and insecticides can damage your bladder's ability to hold water. These include chlorine, trichloroethylene (TCE), diethyltoluamide (DEET), and phthalates.
