Ulcerative Colitis • UC

Ulcerative Colitis

Limited to the colon
  • Starts in rectum – extends up colon
  • Diffuse, continuous pattern of inflammation
  • Mucosa (surface lining) involvement

Crohn’s Disease • CD

Crohn's Disease

Anywhere from the mouth to anus
  • Patchy distribution of inflammation
  • Transmural inflammation (full thickness of
    gut lining = deeper inflammation)
  • Most commonly affects terminal ileum & colon



Abdominal pain
Mucus/blood in stool
Incomplete evacuation
Rectal pain


Weight loss

Most At Risk

Young Adults Aged 15-35

25% of people with IBD develop the disease before the age of 18.

Potential diagnosis at any age

Treat To Target Strategy


Use Steroid-Sparing Strategy To Treat Symptoms

Decrease bleeding, frequency, urgency, pain etc.


Decrease Inflammation

Assessed by blood/stool biomarkers, endoscopic assessment (mucosal healing = bowel healing)


Aspirational Goal = Functional Remission

Having the patient get control of their life again, so they can get back to work, social life, travel, and family gatherings. Gastro of the Rockies has multiple advanced therapies available with varying mechanisms of action and modes of administration (oral, IV, subcutaneous) to target inflammation and treat patients with IBD.

IBD & IBS: Similarities & Differences

Inflammatory Bowel Disease (IBD) is the  Inflammation or destruction of the bowel wall,  leading to sores & narrowing of the intestines. It is a structural disease where physical damage causes symptoms. Doctors can see chronic inflammation or ulcers when they inspect the gut.

Irritable Bowel Syndrome (IBS) is a disorder of the gastrointestinal (GI) tract. It is a functional disease, which means that tests (such as a colonoscopy, stool or blood tests) won’t show any physical reason for symptoms. It’s possible to have both IBD and IBS.

  • Cramping
  • Bloating

IBS Symptoms
