What Are the Symptoms of Cystitis?

Common symptoms of cystitis include frequent and urgent urination, painful urination, a sensation of heaviness or dull pain in the lower abdomen, changes in urine appearance, and mild fever. Most cases result from bacterial infection irritating the bladder mucosa. Severity varies among individuals; seek immediate medical attention if you experience hematuria (blood in the urine) or high fever.

1. Frequent and urgent urination: Inflammation irritates the bladder mucosa, significantly increasing bladder sensitivity and leading to markedly increased urinary frequency. Even small volumes of urine may trigger a strong urge to void, and some individuals may awaken repeatedly at night to urinate. Frequent urination can disrupt normal rest; therefore, adequate hydration is essential—do not intentionally delay urination.

2. Painful urination: A stinging or burning sensation may occur in the urethra and bladder region during urination, and discomfort often persists after voiding ends. Urine flow over inflamed mucosa may exacerbate local irritation. Do not reduce fluid intake out of fear of pain—sufficient water intake helps flush the urinary tract.

3. Lower abdominal heaviness and dull pain: A sensation of pressure or dull ache may develop in the lower abdomen—the anatomical location of the bladder—and palpation may intensify this discomfort. With persistent inflammation, these abdominal symptoms may recur. Prioritize rest, avoid strenuous physical activity, minimize abdominal pressure, and thereby alleviate associated pain.

4. Changes in urine appearance: Inflammation may cause urine to appear cloudy; some patients may notice trace amounts of blood (microscopic or gross hematuria). Urine may also emit an unusual odor, suggesting a urinary tract infection. Monitor your urinary habits closely and observe urine color; do not self-medicate with antibiotics or other drugs upon noticing abnormalities.

5. Mild fever: Simple cystitis typically presents with low-grade fever, reflecting mild systemic inflammatory response. Persistent high fever, however, may indicate ascending infection spreading to the kidneys—a sign of disease progression. Regularly monitor body temperature and integrate this information with urinary symptoms to accurately assess your clinical status.

In daily life, maintain good perineal hygiene, change undergarments frequently, drink ample warm water, avoid holding urine, follow a light diet, and limit intake of spicy or irritating foods to reduce the risk of recurrent cystitis.
