Interstitial Cystitis: Signs and Symptoms

Medical Author: Melissa Conrad Stöppler, MD

Symptoms of interstitial cystitis include urinary urgency and frequency.About 750,000 people in the U.S. (about 90% of whom are women) suffer from a chronic condition of the bladder known as interstitial cystitis. Interstitial cystitis (IC) refers to a clinical syndrome characterized by symptoms including chronic urinary urgency (feeling the need to urinate immediately) and frequency (frequent urination). Pelvic pain may or may not be present. The term cystitis refers to any inflammation of the bladder. Since the wall of the bladder is inflamed, this can lead to pain and soreness in the bladder and pelvic areas. The inflammation can also lead to scarring of the bladder wall that can sometimes reduce the capacity of the bladder to hold urine. In many cases of interstitial cystitis, small hemorrhages and ulcers are present on the inner lining of the bladder wall.

Interstitial cystitis is diagnosed when the symptoms occur without evidence for another cause of the symptoms, such as an infection of the bladder.

Overview of urinary function

The urinary system consists of the kidneys, ureters, bladder, and urethra. The kidneys, a pair of purplish-brown organs, are located below the ribs toward the middle of the back. The kidneys remove water and waste from the blood in the form of urine, keeping a stable balance of salts and other substances in the blood. The kidneys also produce erythropoietin, a hormone that stimulates the formation of red blood cells. Narrow tubes called ureters carry urine from the kidneys to the bladder, a triangle-shaped, muscular chamber in the lower abdomen. Like a balloon, the bladder's muscular, elastic walls relax and expand to store urine and contract and flatten when urine is emptied through the urethra. The typical adult bladder can store about 1 ½ cups of urine.

Adults urinate about 1 ½ quarts of urine each day. The amount of urine varies depending on the fluids and foods a person consumes. The volume formed at night is about half that formed during the day.

Normal urine contains fluids, salts and waste products, but it is free of bacteria, viruses, and fungi. The tissues of the bladder are isolated from urine and toxic substances by a coating on the inside of the bladder that discourages bacteria from attaching and growing on the bladder wall.

ENABLEX is a prescription medicine used in adults to treat the following symptoms due to a condition called overactive bladder:

  • · having a strong need to go to the bathroom right away (also called "urgency")
  • · leaks or wetting accidents (also called "urinary incontinence")

General Health and Wellness

There is credible information available to women not only on such problems as eating disorders, stress, alcoholism, addictions, and depression, but also on basic topics such as good nutrition and exercise. For example, it is beneficial that a woman maintain her optimum weight. If a woman's waist size measures more than 35 inches (89 cm), she is more likely to develop heart disease, high blood pressure, and diabetes. Eating sensible meals, eliminating after- dinner snacks, and making physical activity a part of daily life are significant ways to help control weight and lower the risk of a long list of health problems.

Smoking is detrimental to a woman's health (or to anyone else's). Unfortunately, women continue to smoke despite the known health risks. Even though the number of women smoking is declining, still about 19% of women in the U.S. were smokers in 2003. Women are smoking in spite of the well-publicized...
