Chronic Intestinal Inflammation: Fatigue and Weight Loss as Warning Signs
Prolonged fatigue and unintentional weight loss can be signs of inflammatory bowel diseases such as Crohn's disease and ulcerative colitis, warns Dnevno.hr.
Prolonged fatigue and unintentional weight loss can be signs of inflammatory bowel diseases such as Crohn's disease and ulcerative colitis, warns Dnevno.hr.
People often attribute digestive issues to stress, poor diet, or short-term problems, but if symptoms recur regularly, last for several weeks, or worsen over time, they should be taken seriously. As Dnevno.hr reports on August 17, 2026, they can sometimes indicate inflammatory bowel diseases, the most well-known being Crohn's disease and ulcerative colitis.
These diseases are chronic in nature and are characterized by alternating phases of active inflammation and periods without symptoms. They are commonly associated with diarrhea, abdominal pain, and blood in the stool, but symptoms vary from patient to patient. The disease can progress slowly, and some signs may not be related to the digestive system at all.
One symptom that is often overlooked is prolonged and unexplained fatigue. A person may feel exhausted even after getting enough sleep, and everyday tasks may suddenly seem like a much greater effort than before. This can be due to the chronic inflammation itself, as well as anemia resulting from bleeding in the digestive tract, reduced absorption of iron and other nutrients, or insufficient food intake.
Unintentional weight loss can also be a warning sign. Active inflammation can interfere with the absorption of nutrients, and pain or discomfort after meals can lead to reduced food intake. Special attention should be paid if a person loses weight without changes in diet or physical activity, while also experiencing diarrhea, abdominal pain, or pronounced fatigue.
Occasional elevated body temperature without an obvious cause can also be a sign of active inflammation. Fever alone does not prove inflammatory bowel disease, but if it occurs alongside persistent digestive issues, it may warrant medical evaluation.
Anemia is also common in people with inflammatory bowel diseases. In addition to fatigue, it can cause paleness, weakness, dizziness, rapid heart rate, and shortness of breath on exertion.
Crohn's disease and ulcerative colitis do not necessarily affect only the intestines. These are systemic diseases that can, in some patients, cause symptoms outside the digestive system. These include joint pain and inflammation, skin changes, mouth ulcers, and eye inflammation. If the eye suddenly becomes red, painful, or very sensitive to light, medical evaluation is necessary.
Changes in bowel habits are one of the most important warning signs. Diarrhea that lasts a long time or occurs frequently, mucus in the stool, cramps and abdominal pain, and a strong, sudden urge to use the toilet can be signs of inflammatory bowel disease. In ulcerative colitis, there may also be a feeling that the bowels are not completely emptied, or a constant need to go to the bathroom.
Occasional digestive issues are very common and usually do not indicate a serious illness. However, a check-up should not be delayed if symptoms persist or recur, especially if blood appears in the stool, prolonged diarrhea, unexplained weight loss, fever, severe weakness, or strong and persistent abdominal pain occur.
It is important to note that these symptoms are not specific only to Crohn's disease and ulcerative colitis. They can also occur with infections, celiac disease, irritable bowel syndrome, and many other conditions, so a diagnosis cannot be made based on symptoms alone.
A doctor may, if necessary, perform blood tests and stool analysis, including fecal calprotectin, which can help assess the presence of inflammation in the intestines. Depending on the results, endoscopic or imaging tests may be indicated. Timely detection of the disease is crucial for controlling inflammation and reducing the risk of complications.
