Ankylosing spondylitis and inflammatory bowel disease

Inflammatory bowel disease includes Crohn's disease and ulcerative colitis. It causes persistent inflammation in the digestive tract, while ankylosing spondylitis primarily targets the sacroiliac joints and spine. Symptoms in the bowel and joints do not necessarily worsen at the same time.

Ongoing diarrhoea, blood or mucus in the stool, repeated abdominal pain, urgency, waking at night to open the bowels, unexplained weight loss, or persistent fatigue can point to bowel inflammation. These features deserve assessment rather than being attributed automatically to diet or a medicine.

Short-lived digestive upset has many possible causes and does not by itself establish inflammatory bowel disease. A clinician considers the symptom pattern, examination, blood and stool tests, and sometimes specialist investigations before making the diagnosis.

Tell the rheumatology clinician about persistent bowel changes and tell the gastroenterology clinician about back, joint, or heel symptoms. A shared medicine list matters because some treatments can help inflammation in both areas, while others may suit one condition better than the other.

Do not stop prescribed medication abruptly. If a pain medicine seems to aggravate abdominal symptoms, seek advice before taking further doses; anti-inflammatory medicines require individual consideration when bowel disease is present. Keep a brief record of stool changes, abdominal pain, joint stiffness, medicines, and missed activities to make appointments more informative.

During a flare, choose tolerable movement and maintain hydration if stools are loose. A clinician can tailor exercise when fatigue, abdominal pain, or active joint inflammation makes the usual routine difficult.

Arrange timely review for persistent diarrhoea, recurring blood in the stool, unexplained weight loss, ongoing abdominal pain, or bowel symptoms that wake you. Seek urgent care for heavy bleeding, black tar-like stool, severe or rapidly worsening abdominal pain, repeated vomiting, a swollen abdomen, fainting, confusion, or signs of marked dehydration.

Fever with severe abdominal symptoms also warrants urgent assessment. The need for care comes from the bowel warning signs themselves, not from whether the spinal condition is currently active.

Ask whether your bowel pattern needs stool testing or gastroenterology assessment, which pain relief options fit your digestive history, and whether one treatment could address both conditions. Clarify who to contact during a flare and which monitoring belongs with each specialist.
