November offers an opportunity to learn about Crohn’s disease and ulcerative colitis and to support people living with inflammatory bowel disease (IBD). Whether you know someone with IBD or have questions about persistent digestive changes, understanding the basics can help you have a more informed conversation with a healthcare professional.

What is IBD, and how is it different from IBS?
IBD stands for inflammatory bowel disease, not “irritable bowel disease.” Its two main forms are Crohn’s disease and ulcerative colitis. Both involve chronic inflammation in the digestive tract. Crohn’s disease can affect different parts of the digestive tract, while ulcerative colitis affects the colon and rectum.
Irritable bowel syndrome (IBS) is a different condition involving changes in how the gut functions and interacts with the brain. It does not cause the same inflammation and tissue damage as IBD. Both can affect quality of life, and symptoms can overlap. Symptoms alone cannot reliably distinguish them; a clinician can assess what investigations are appropriate.
Common questions about IBD
What causes IBD?
There is no single established cause. Research points to interactions among genetic susceptibility, immune responses, environmental factors, and the gut microbiome. IBD is not simply the result of stress or something a person ate.
What symptoms might prompt a conversation?
Persistent or recurring diarrhoea, abdominal pain, bowel urgency, fatigue, blood in the stool, and unexplained weight loss warrant medical attention. These symptoms can have many causes; noticing them does not mean you have IBD.
Can food, probiotics, or supplements replace medical care?
No. General gut-health advice is not a substitute for IBD assessment or care. Evidence for probiotics varies by condition and preparation; a benefit in one setting should not be assumed to apply to another. Dietary needs also vary, particularly during periods of active symptoms. Discuss significant dietary changes and supplements with your clinician or a registered dietitian familiar with IBD.
For background on the terminology, read Probiotics vs. Prebiotics: What's the Difference and Why You Need Both. This general education does not establish that either prevents or treats IBD.
The gut–brain connection and emotional wellbeing
Living with ongoing digestive symptoms can be emotionally demanding. The gut and brain communicate in both directions, and stress can influence the experience of digestive symptoms. This does not mean IBD is caused by anxiety or that symptoms are “all in your head.” Emotional support can be valuable alongside medical care.

When to consult a clinician
Arrange an assessment for persistent or recurring digestive changes, unexplained weight loss, or ongoing fatigue. Contact a healthcare professional promptly about blood in your stool rather than waiting several weeks.
Seek urgent medical care for severe or worsening abdominal pain, heavy or ongoing bleeding, black tarry stools, fainting, or signs of significant dehydration. If symptoms appear life-threatening, call 911.
A primary-care clinician can review your symptoms and decide whether tests or a specialist referral are needed. If you already have IBD, follow your care team’s advice for new or worsening symptoms.
Preparing for a useful appointment
Write down when symptoms started, how often they occur, any changes in bowel habits, and the medicines or supplements you use. Note questions you want answered. A symptom record can support the conversation, but it cannot diagnose a condition.
Awareness starts with understanding
This November, make space for accurate information and compassionate conversations. Avoid assuming that someone’s symptoms reflect their food choices or stress levels. At DigestWell Co., we encourage informed questions and appropriate professional care, not self-diagnosis or promises of a quick fix.
