Why do I still feel urgency despite OAB treatment?

Question

Hi doctor,

I am a 47-year-old woman who frequently experiences urges to urinate, especially at night, sometimes every hour. My urine tests and ultrasound results were normal, and my doctor mentioned that I might have an overactive bladder. I have been prescribed Mirabegron, but I still feel some urgency.

Is this condition curable, or is it only manageable with medication?
Could pelvic floor exercises or bladder training be helpful in the long term?
Additionally, I drink about 2.5 liters of water daily. Should I consider reducing this amount?
Sometimes I notice a burning sensation during urination, even when my tests show no infection. Can hormonal changes or stress exacerbate bladder sensitivity over time?

Please help.

Hi,

Welcome to icliniq.com.

I am genuinely concerned about your worries.

Your symptoms are very typical of overactive bladder (OAB). This condition means the bladder muscle becomes overly sensitive and contracts suddenly, even when it is not very full. That is why you feel a strong urgency and frequent urination, especially at night, even though tests are normal.

Overactive bladder is usually a chronic condition, but it can be well-controlled. Many patients improve significantly with proper treatment. It is more about long-term management rather than a permanent cure, but symptoms often become much milder over time.

Mirabegron helps relax the bladder muscle, but it may take four to eight weeks for the full effect. Sometimes, dose adjustment or combining with another medication is needed. If urgency persists, your doctor may reassess treatment options.

Pelvic floor exercises (Kegel exercises) and bladder training are extremely helpful long-term. These techniques retrain the bladder to hold urine longer and reduce the frequency of urgency episodes. When done regularly for a few months, they can make a big difference and reduce dependence on medicines.

Regarding water intake, 2.5 liters daily may be slightly high for someone with OAB, especially if you are not very active. You do not need to restrict severely, but reducing to around 1.5 to 2 liters and avoiding fluids two to three hours before bedtime may help nighttime frequency. Also, reduce caffeine and artificial sweeteners, as they irritate the bladder.

Burning sensation without infection can happen due to bladder hypersensitivity. It does not always mean infection. Sometimes anxiety, stress, or hormonal changes (especially around perimenopause or menopause) can increase bladder sensitivity.

Hormonal changes, particularly reduced estrogen, can worsen urinary urgency and frequency over time. Stress also increases bladder nerve sensitivity.

The good news is that OAB does not damage the kidneys or cause serious disease. With a combination of medication, pelvic exercises, fluid adjustment, and stress control, most women achieve good long-term control and improved quality of life.

If you have any more questions, feel free to ask. I would be happy to guide you. Please keep your valuable feedback for better patient care.

Thank you so much.
