Crohn's flares start when the immune system overreacts, often triggered by factors like missed medications, stress, smoking, infections, or certain NSAIDs, causing increased inflammation, leading to symptoms such as intense diarrhea, abdominal pain, fatigue, and weight loss, though flares can occur unpredictably even when doing everything right.
What Are Common Crohn's Triggers?
Signs of a flare-up include going for a poo more than 5 times in 24 hours – or more than is normal for you, loose poo or diarrhoea with blood or mucus for more than 3 days and abdominal pain. Everyone experiences flare-ups differently. They can last anywhere from a few days to several months.
The symptoms can come on gradually, but they can also show up suddenly. And these can include diarrhea, fever, fatigue, abdominal pain and cramping, blood in your stool, mouth sores, reduced appetite and weight loss.
The exact cause of Crohn's disease is not clear. It is probably a combination of genetics, the immune system, and something in the environment that triggers inflammation in the gastrointestinal tract. Diet and stress may make symptoms worse, but probably don't cause the condition.
Intestinal conditions mimicking Crohn's disease
Abnormal immune reaction
One cause of Crohn's disease may be an abnormal reaction of your body's immune system, which happens when your immune system attacks bacteria that tend to live in your intestines. This immune system response causes inflammation in the digestive tract, leading to Crohn's disease.
The disease can occur at any age, but Crohn's disease is most prevalent in adolescents and adults between the ages of 15 and 35. Diet and stress may aggravate Crohn's disease, but do not cause the disease. Recent research suggests hereditary, genetic, and environmental factors contribute to Crohn's disease development.
Sticking to bland foods and clear liquids such as vegetables, lean meats, and broth-based soups can reduce the chances of exacerbating the flare-up. Many patients with Crohn's disease are susceptible to dehydration during a flare, especially because diarrhea is common.
Clusters of inflammatory cells called granulomas may suggest a diagnosis of Crohn's disease. CT scan. A CT scan is a special X-ray technique that provides more detail than a standard X-ray does. This test looks at the entire bowel as well as at tissues outside the bowel.
Metastatic Crohn's disease causes plaques or nodules (solid raised bumps) that may be purple or red, with possible ulceration (open sores). Metastatic Crohn's disease can also appear as a rash around the genital and anal areas, which can cause ulcers or abscesses.
You may need to seek medical treatment for a Crohn's flare if your symptoms are severe because this could mean your medications aren't working. In addition, a high fever, blood clots in your stool, and an inability to keep liquids down may require emergency medical attention.
The pain is most commonly associated with Crohn's affecting the small intestine, though cramping of all kinds can occur no matter what part of your GI is inflamed. Many patients will experience abdominal pain on the lower right side of their abdomen or around their navel, typically occurring 1 to 2 hours after eating.

5 foods to avoid with Crohn's disease.
Patients who develop Crohn disease often present with abdominal pain, chronic diarrhea, weight loss, and fatigue. Extraintestinal manifestations, including arthropathy and skin lesions, may also occur. Diagnosis is established using endoscopy, histopathology, and cross-sectional imaging.
They usually come and go over time, called flare-ups and remissions. A flare-up can last from a few days to several months. You may also have symptoms affecting other parts of your body, such as joint pain, sore eyes and skin rashes.
Water remains your best bet for staying adequately hydrated, and low-sugar electrolyte drinks can be very beneficial, too. Some drinks like soda and fruit juices can exacerbate Crohn's symptoms due to carbonation or high sugar content, so consider limiting or avoiding these if they trigger your symptoms.
In the beginning, you may notice signs of mild UC, including:
Other symptoms of Crohn's disease
Adding fiber-rich options like leafy greens, broccoli, and whole grains can help improve gut function and support a healthy microbiome. Fermented foods, including yogurt, kefir, and kimchi, introduce beneficial probiotics that aid in reducing gut inflammation and improving digestion.
Although ulcerative colitis and Crohn's disease are both long-term, inflammatory conditions that affect the digestive tract, ulcerative colitis (UC) may be considered “worse” because surgery may be required earlier and, in certain circumstances, more urgently, in people with severe and extensive UC.
Mild Crohn's disease: This typically occurs in 20% to 30% of people with Crohn's. Symptoms and disease activity are mild (you don't require hospitalization) and there are no complications, according to the journal Current Gastroenterology Reports. Symptoms typically include abdominal pain and diarrhea.
Crohn's disease can manifest with a variety of symptoms. Mimics of Crohn's disease include alternate gastrointestinal diseases, vascular causes, autoimmune processes, infections, malignancies and complications, drug- or treatment-induced conditions, and genetic diseases.
