Crohn's disease in the small intestine

The small intestine digests food and absorbs nutrients. Crohn's disease can inflame its lining and, over time, narrow an affected segment. This may lead to cramping, abdominal pain, loose stools, tiredness, reduced appetite, or unintended weight loss. The pattern varies with the location and activity of inflammation.

A narrowing can make food and fluid pass less easily. Symptoms such as bloating, vomiting, worsening cramps, or inability to pass stool or gas need prompt attention. These symptoms are not specific to Crohn's disease, so assessment is needed to identify the cause.

Book a GP Consultation if symptoms persist, recur, or interfere with eating and daily activities. Describe stool changes, pain location, appetite, weight change, fever, and any previous bowel diagnosis. A Blood Test can help check for inflammation or anaemia and may guide further evaluation. Your clinician may arrange additional tests or specialist review based on the whole picture.

Until reviewed, drink fluids regularly and keep a simple record of foods, symptoms, and bowel movements. Do not make major dietary restrictions without professional guidance, particularly if your appetite is low or you are losing weight.

Seek urgent care for severe or persistent abdominal pain, repeated vomiting, a swollen abdomen, inability to pass stool or gas, blood in the stool, high fever, faintness, or signs of dehydration such as very little urine and marked dizziness. These features can signal a complication or another condition requiring timely examination.

Which part of my small intestine may be involved? Could my symptoms reflect narrowing or active inflammation? Do I need a Blood Test or specialist assessment? How can I maintain nutrition while symptoms continue?
