E N D
Menstrual Cycle and Bowel-Pattern Fluctuations • Bowel-pattern fluctuation is common during the menstrual cycle • IBD symptoms may increase during the menstrual cycle • Suppression of menses via hormonal contraceptive methods may be considered in presence of debilitating symptoms
Potential IBD-RelatedMenstrual Symptoms • Most frequently reported symptoms • Pelvic pain 52% • Lower back pain 36% • Diarrhea 26% • Irritability 23% • Headache 20% • Incidence of any menstrual symptoms significantly higher for IBD patients than for healthy controls (P.01) Kane SV, et al. Am J Gastroenterol. 1998;93:1867-1872.
IBD: Issues With Menstruation • There is a trend for patients with CD to be affected by IBD symptoms during menstruation to a greater extent than are patients with UC • CD patients experienced diarrhea significantly more often than did controls (P=.004) Kane SV, et al. Am J Gastroenterol. 1998;93:1867-1872.
OCs and IBD Risk • Controversial data • Increased incidence of CD with use of OCs? • OCs related to flare of CD activity? • Newer OCs with lower estrogen content associated with decreasing incidence of CD in women?

Contraindications for OCs • History of thromboembolic disease • Active obstructive liver disease with elevated liver enzymes • Breast cancer • Smokers over the age of 35 • Pregnancy
IBD and Contraception: Conclusions • OCs should have lower estrogen content (eg, 35 µg) • Avoid for women with known hypercoagulability • Avoid for women with IBD-associated liver disease • Avoid for women with IBD who smoke
