IBD and Your Period


Having inflammatory bowel disease (IBD, Crohn’s disease, ulcerative colitis, or indeterminate colitis) may affect the menstrual cycle. Menstruating people should be aware of the changes that may occur over a lifetime of living with IBD.

IBD and Your Period

  • IBD is a diagnosis of young people: It’s common to be diagnosed between the ages of 15 and 35
  • What’s “normal” is a range: Periods can change over time and are different between individuals
  • Patterns are important: Charting periods over time will help in understanding your “normal”
  • Differences in the 1st year: In the year before or after an IBD diagnosis, periods might change
  • IBD and period symptoms: Women with IBD report more nausea, gas, and abdominal pain during their period than women who don’t have IBD
  • IBD diagnosis may matter: Women with Crohn’s disease report period symptoms more often than do those with ulcerative colitis

Symptoms to Bring to Your Doctor

  • Periods closer than every 21 days or further apart than every 45 days
  • 90 days+ between periods
  • A period lasting more than 7 days
  • Heavy bleeding and changing pads or tampons every 1 to 2 hours
