-
Stomach pain and cramps
-
Blood or mucus in your stool
-
Feeling like you need to use the bathroom right away
-
Feeling very tired
-

Inflammatory Bowel Disease Symptoms That Should Not Be Ignored
If your digestive symptoms do not improve or get worse, it could indicate ongoing inflammation in your intestines. You should see a doctor for a proper check-up in case of the following symptoms:
| Symptom | What It May Indicate |
| Persistent diarrhoea lasting more than a few weeks | Ongoing intestinal inflammation |
| Blood in the stool | Ulceration or bleeding in the digestive tract |
| Severe abdominal pain | Intestinal inflammation, obstruction or perforation |
| Unexplained weight loss | Poor nutrient absorption or severe disease |
| High fever with persistent diarrhoea or abdominal pain | Severe inflammation or intestinal infection |
| Persistent fatigue | Chronic inflammation or anaemia |
| Painful swelling around the anus | Perianal Crohn's disease |
| Frequent nighttime diarrhoea | Active inflammatory bowel disease |
Why Do Inflammatory Bowel Disease Symptoms Occur?
Inflammatory bowel disease occurs when the immune system mistakenly attacks the digestive tract, causing ongoing inflammation. In Crohn's disease, inflammation can affect any part of the digestive tract, while ulcerative colitis mainly affects the colon and rectum. Persistent inflammation damages the intestinal lining, leading to ulcers, bleeding and diarrhoea. Damage to the small intestine may reduce nutrient absorption, causing weight loss, fatigue, and nutritional deficiencies. Inflammation may also affect the joints, skin, eyes and liver, producing symptoms outside the digestive system.
Inflammatory Bowel Disease Symptoms That Require Immediate Medical Attention
If you have inflammatory bowel disease and notice any of these symptoms, seek medical help immediately:
-
Severe abdominal pain
-
Persistent vomiting
-
High fever with chills
-
Heavy rectal bleeding
-
Severe dehydration
-
Inability to pass stools or gas
-
Rapid heart rate with dizziness or fainting
-
Severe abdominal swelling
-
Loss of consciousness
-
Signs of bowel perforation or toxic megacolon
These symptoms may be signs of serious problems that require emergency care.
Symptoms of Inflammatory Bowel Disease Based on Type
Different types of inflammatory bowel disease may exhibit different symptoms, which may require medication evaluation. The table below lists symptoms of inflammatory bowel disease based on type:
| Type | Symptoms |
| Crohn's Disease | Abdominal pain, chronic diarrhoea, weight loss, mouth ulcers, perianal fistulas or abscesses, nutritional deficiencies, anal pain |
| Ulcerative Colitis | Bloody diarrhoea, frequent bowel movements, urgency to pass stools, rectal bleeding, abdominal cramping, fatigue |
Inflammatory Bowel Disease Symptoms in Women
Women with inflammatory bowel disease often experience digestive symptoms similar to men, but changes in hormones can affect how the disease behaves. Some women find their symptoms get worse during their period. Moreover, if IBD is not well-managed, it can impact fertility and pregnancy.
Women might notice the following IBD symptoms:
-
Menstrual cycles may become irregular when the disease is active.
-
Gastrointestinal symptoms may worsen before or during menstruation.
-
Iron-deficiency anaemia may occur.
-
Fertility may decrease when inflammation is active.
Inflammatory Bowel Disease Symptoms in Children
In addition to digestive symptoms, inflammatory bowel disease may affect normal growth and development in children because of poor nutrient absorption and chronic inflammation. Symptoms may include:
-
Persistent diarrhoea
-
Blood in the stool
-
Recurrent abdominal pain
-
Weight loss or poor weight gain
-
Delayed growth and puberty
-
Loss of appetite
-
Joint pain
-
Mouth ulcers
Can You Have Inflammatory Bowel Disease Without Symptoms?
During periods of remission, many people experience few or no symptoms of inflammatory bowel disease, even though low-grade inflammation may still be present in the digestive tract. This is sometimes referred to as subclinical disease activity. Regular follow-up with blood tests, stool markers such as faecal calprotectin, imaging or colonoscopy helps monitor inflammation even when symptoms are absent.
When Can Inflammatory Bowel Disease Symptoms Become Life-Threatening?
The following table provides an overview of conditions related to inflammatory bowel disease and why they are serious:
| Emergency Condition | Why It Is Serious |
| Severe intestinal bleeding | Can lead to significant blood loss and shock. |
| Toxic megacolon | Severe inflammation causes the colon to enlarge rapidly and may lead to rupture. |
| Bowel perforation | A hole in the intestine can cause a life-threatening infection. |
| Severe dehydration | Persistent diarrhoea and vomiting can cause dangerous fluid and electrolyte loss. |
| Intestinal obstruction | Narrowing or blockage of the intestine prevents the normal passage of food and waste. |
| Severe infection (sepsis) | Infections related to bowel perforation or abscesses can spread throughout the body. |
| Colorectal cancer | Long-standing IBD increases the risk of developing colorectal cancer. |
How are Inflammatory Bowel Disease Symptoms Diagnosed?
Firstly, a healthcare professional will look at your symptoms and medical history and then perform a physical examination. After that, they may suggest tests to confirm inflammatory bowel disease and rule out other digestive problems. These tests may include:
| Diagnostic Test | Purpose |
| Blood tests | Detect anaemia, infection and markers of inflammation. |
| Stool tests | Identify intestinal inflammation and rule out infections. |
| Colonoscopy with biopsy | Examines the colon and confirms the diagnosis through tissue samples. |
| Flexible sigmoidoscopy | Evaluates inflammation in the rectum and lower colon. |
| Upper gastrointestinal endoscopy | Assesses involvement of the upper digestive tract when needed. |
| CT scan | Detects bowel inflammation, abscesses and complications. |
| MRI enterography | Provides detailed images of the small intestine, especially in Crohn's disease. |
| Capsule endoscopy | Examines areas of the small intestine that cannot be reached by conventional endoscopy. |
FAQs
-
Q1. What is the first symptom of inflammatory bowel disease?
Ans: Persistent diarrhoea, abdominal pain and blood in the stool are among the earliest symptoms of inflammatory bowel disease. -
Q2. Can inflammatory bowel disease occur without symptoms?
Ans: Yes. During remission, symptoms of inflammatory bowel disease may disappear, although inflammation may still be present in the digestive tract. -
Q3. Which inflammatory bowel disease symptoms require emergency medical attention?
Ans: Inflammatory bowel disease symptoms, such as heavy rectal bleeding, severe abdominal pain, persistent vomiting, high fever, severe dehydration and inability to pass stools or gas, require immediate medical care.
