Ulcerative Colitis and Crohn’s Disease : 5 Common Signs and When to See a Doctor

Ulcerative Colitis and Crohn’s Disease : 5 Common Signs and When to See a Doctor

Inflammatory Bowel Disease (IBD) is more than just a “sensitive stomach.” It is a chronic condition characterised by inflammation in the digestive tract.

It is an important cause of abdominal pain, constipation and diarrhoea in younger people. It should be considerd in any younger person if such symptoms occur for more than 2 weeks.

The two primary types are Ulcerative Colitis (UC) and Crohn’s Disease.

While they share similar symptoms, they affect the body differently. Ulcerative colitis is limited to the colon and rectum, affecting only the innermost lining.

Crohn’s disease can occur anywhere from the mouth to the anus and often involves all layers of the intestinal wall.

5 Common Signs of IBD

Recognizing the symptoms early is key to managing the condition and preventing long-term damage.

1. Persistent Diarrhoea: This is often the most common sign. Unlike a temporary stomach bug, IBD-related diarrhea lasts for weeks and may wake you up in the middle of the night.

2. Abdominal Pain and Cramping: While gas can cause discomfort, IBD pain is often severe and chronic. UC pain is typically felt in the lower left abdomen, while Crohn’s pain is more common in the lower right.

3. Blood in the Stool: You might notice bright red blood or darker, tarry stools. This is a hallmark of inflammation or ulcers in the intestinal lining.

4. Unexplained Weight Loss: Chronic inflammation can interfere with how your body absorbs nutrients (malabsorption) or suppress your appetite, leading to sudden weight loss.

5. Extreme Fatigue: This isn’t just “being tired.” IBD fatigue is an overwhelming exhaustion often caused by the body’s immune response, blood loss (anemia), or poor sleep due to symptoms.

Causes and Risk Factors

Science hasn’t pinpointed a single “cause” for IBD yet, but researchers in 2026 focus on a “perfect storm” of three factors:

• Immune System Malfunction: Instead of fighting off viruses, the immune system mistakenly attacks the healthy cells in the digestive tract.

• Genetics: If a close family member has IBD, your risk is significantly higher.

• Environmental Triggers: Factors like smoking (especially for Crohn’s), high-stress levels, and diets high in processed foods or “Western” fats may trigger flares.

Treatment Options

While there is currently no cure, modern medicine allows most people to live full, active lives.

• Medications: Doctors often prescribe biologics (targeted proteins), JAK inhibitors, or corticosteroids to reduce inflammation and induce remission.

• Lifestyle & Diet: Identifying “trigger foods” (like dairy or high-fiber raw veggies during a flare) and managing stress can reduce the frequency of symptoms.

• Surgery: In severe cases of UC, removing the colon can be curative. For Crohn’s, surgery may be used to remove damaged sections or treat complications like fistulas.

When to See a Doctor

You should schedule an appointment with a gastroenterologist if you experience a lasting change in bowel habits (longer than 2–4 weeks).

Seek Urgent Medical Care If:

• You have a high fever or chills alongside abdominal pain.

• You are experiencing “nocturnal diarrhea” (waking up to go).

• There is significant, persistent blood in your stool.

• You have signs of severe dehydration or “toxic megacolon” (severe bloating and rapid heartbeat).

Early diagnosis through a colonoscopy or fecal calprotectin test is the “gold standard” for getting your life back on track.
