My doc put me on antibiotic one a day for 3 months but there is no infection but signs of pain and sudden urges and weakness of bladder any ideas?

For overactive bladder, here are some tips:

  • Do Kegel exercises which can help you strengthen your pelvic floor muscles so they can better support the pelvic organs and control urine flow.

  • If you’re overweight, lose weight.

  • Manage fluid intake. Drink about six glasses a day. Water is the ideal choice. Cranberry, grape, cherry, and apple juices are also gentle on your bladder.

  • Eat fiber rich food to avoid constipation. Constipation can worsen OAB symptoms.

  • Avoid highly spiced foods, tomatoes and tomato products, Citrus fruits and juices, Honey, Chocolate, Alcoholic beverages, Carbonated beverages, Caffeinated drinks, Coffee (even decaf)
