When it comes to exacerbating urinary tract infection symptoms, citrus-flavored drinks (imagine your favorite lemon-lime combo) and caffeinated sodas are the culprits. So, if you're fighting a bladder infection, stick to water or cranberry juice as your beverage of choice. Avoid these drink items if you suffer from ulcers or irritable bowel syndrome. Citrus fruits are high in acidity. Too much acid in your body can lead to the formation of stones in your kidneys. Therefore, it is recommended that people with kidney problems avoid drinking too many juices made from citrus fruits. If you're struggling with urinary tract infections (UTIs), then it's important to understand the causes of these infections and how they can be prevented. A UTI is when bacteria enter your urine stream and grow in number. This growth of bacteria can cause symptoms such as pain during urination, feeling like you need to go even though you've already passed water, fever, chills, nausea, and vomiting. If you ignore the symptoms and they don't go away within two weeks, then see your doctor. Your main defense against bacterial infections is your immune system. The more active and effective your immune system is, the less likely you are to get sick.
