The three most common causes of bladder pain and pressure are urinary tract infections, interstitial cystitis and bladder cancer, according to WebMD. Urgency and frequent urination are other symptoms of these conditions. A person experiencing these symptoms should consult a physician to determine the cause and receive treatment.
Urinary tract infections result from bacteria entering the normally sterile urinary tract, says WebMD. They are most common in the bladder but can occur in any part of the urinary system. UTIs are more common in women than in men. Treatment involves antibiotics and increased fluid intake to flush out the bacteria.
Interstitial cystitis is a chronic condition in which the bladder wall becomes inflamed and irritated, causing it to stiffen and reducing its ability to expand normally, explains WebMD. This condition is also more common in women. Treatment typically starts with either oral medication or bladder instillation, in which the doctor places liquid medication within the bladder. Treatment may also involve bladder distention, which can relieve pain and increase bladder capacity. If initial treatments fail, surgery may become necessary to relieve symptoms.
If medical testing shows the presence of bladder cancer, treatment may involve chemotherapy, radiation, immune therapy or surgery, states WebMD. Treatment varies according to how aggressive the cancer is and how much it has spread.
