When to seek medical advice

By Mayo Clinic staff

Call your doctor right away if you experience the following signs and symptoms:

  • Several episodes of loose stools or watery diarrhea for two or more consecutive days
  • Fever
  • Severe abdominal pain or cramping
  • Pus or blood in your stool
  • Lightheadedness or dizziness

These signs and symptoms may indicate a number of conditions, ranging from viral, bacterial or parasitic infections to inflammatory bowel disorders, such as ulcerative colitis or Crohn's disease. In older adults with cardiovascular disease, low blood flow to the colon (ischemic colitis) also can cause these symptoms.

But if you're currently taking antibiotics or have recently finished antibiotic therapy, it's possible you have antibiotic-associated diarrhea. Your doctor can perform tests to determine the exact cause of your problem.
