IBD (Crohn's Disease & Ulcerative Colitis)

What IBD Is

StatPearls describes IBD as repeated episodes of gastrointestinal inflammation caused by an abnormal immune response to gut microflora.^[1] The two main subtypes affect the digestive tract differently. Ulcerative colitis involves diffuse inflammation limited to the colon's inner lining, most commonly presenting as bloody diarrhea with or without mucus, along with tenesmus, a sensation of incomplete evacuation, and abdominal pain.^[1] Crohn's disease causes full-thickness ulceration that can appear anywhere along the GI tract, most often in the terminal ileum and colon.^[1]

Most IBD develops between ages 15 and 30, with up to a quarter of patients diagnosed by adolescence.^[1] Crohn's disease is slightly more common in women than men, while ulcerative colitis appears roughly equally common across sexes.^[1] Both conditions can also affect tissue outside the gut: extraintestinal manifestations include joint inflammation, skin changes, and eye involvement, and hematologic evaluations for IBD commonly note microcytic anemia among the findings.^[1]

Why People Track It

A prevalence study of 234 women with IBD or irritable bowel syndrome found that all disease groups showed a cyclical pattern to their bowel symptoms significantly more than people without these conditions, with a large majority reporting worsened symptoms around their period and Crohn's patients showing a statistically significant rise in GI symptoms during menstruation.^[2] Diarrhea, abdominal pain, and constipation were the symptoms most often reported to cluster with the cycle in that research.^[2] A later review of women's health considerations in IBD lists menstrual-cycle symptom fluctuation as a recognized, if often under-discussed, part of managing the condition.^[3] That's why people with IBD commonly log digestive changes against their cycle rather than in isolation, and why iron-deficiency anemia, one of the hematologic findings associated with IBD, is often tracked alongside gut symptoms rather than treated as unrelated.

How Go Go Gaia Supports Tracking It

Go Go Gaia doesn't diagnose or treat IBD. If you add it in the app, quick-logs default to stomach pain and diarrhea, with constipation and fatigue available as additional picks, and food logging stays linked to the condition so meals sit on the same timeline as flare days and your cycle.

What the Research Shows

Kane, Sable, and Hanauer's 1998 prevalence study in the American Journal of Gastroenterology remains a frequently cited source on this question: among 234 women with IBD or IBS, 93% reported premenstrual symptoms, and all disease groups had a cyclical bowel-symptom pattern significantly more often than controls.^[2]

A 2019 review in Current Opinion in Gastroenterology situates that cyclical symptom pattern within a broader set of women's health considerations in IBD, alongside topics like fecal incontinence and sexual health, arguing these deserve more attention in routine care.^[3]

StatPearls' overview of IBD notes that neither Crohn's disease nor ulcerative colitis is curable, and that the relapsing-remitting course, active flares followed by quieter stretches, is central to how both conditions are managed over the long term.^[1]

Frequently Asked Questions

Educational information based on published sources. Not medical advice. For personal concerns, please consult your doctor.

What is IBD?

IBD (inflammatory bowel disease) is an umbrella term for Crohn's disease and ulcerative colitis, chronic conditions caused by an abnormal immune response that produces long-term inflammation of the digestive tract. Symptoms come in flares, active stretches followed by calmer periods.^[1]

What's the difference between Crohn's disease and ulcerative colitis?

Ulcerative colitis involves diffuse inflammation limited to the inner lining of the colon. Crohn's disease can cause full-thickness inflammation anywhere along the GI tract, most often the terminal ileum and colon.^[1]

Does the menstrual cycle affect IBD symptoms?

Research has studied this directly. A prevalence study of 234 women with IBD or IBS found that all groups showed a cyclical pattern to their bowel symptoms significantly more than people without these conditions, with a majority reporting worsened symptoms around their period.^[2]
