Key points
- Diarrhoea, abdominal pain, weight loss and fatigue are common but require testing because infection and other bowel disease can look similar.
- Treatment aims for healing and complication prevention, not only temporary suppression of symptoms.
- Corticosteroids can induce remission but are unsuitable for long-term maintenance because cumulative harms are substantial.
The listings below are not interchangeable Crohn’s therapies; disease location, behaviour, severity and infection risk guide selection.
Measuring disease and complications
Blood and stool inflammation markers, ileocolonoscopy and small-bowel imaging define extent and activity. Perianal examination matters when pain or drainage is present. Anaemia, nutrition, bone health and extraintestinal joint, skin or eye disease are assessed alongside bowel symptoms.
Building durable control
Immunomodulators, biologics and targeted oral medicines have different mechanisms, onset and monitoring needs. Screening for tuberculosis, hepatitis and vaccination status precedes significant immune suppression. Surgery treats obstruction, abscess or damaged bowel but does not eliminate the underlying tendency to recur.
When to seek urgent care
Seek urgent care for severe or increasing abdominal pain, repeated vomiting, a swollen abdomen, inability to pass stool or gas, heavy bleeding, high fever or a painful perianal swelling.

What is Crohn's disease?
Crohn's disease is a long-term condition in which the immune system inflames the gut, flaring up and settling again. It can affect any part of the digestive tract and can cause narrowing, abnormal channels between organs (fistulas) or abscesses.
What are the symptoms of Crohn's disease?
Common symptoms include diarrhoea, abdominal pain, weight loss and fatigue. Tests are needed because infections and other bowel conditions can look similar.
How is Crohn's disease treated?
Treatment aims to heal the gut and prevent complications, not just ease symptoms for a while. Corticosteroids can bring the disease under control but are not suitable long term, because they cause serious side effects when used for a long time. Medicines that calm the immune system, including biologics and newer tablets, work in different ways and need different monitoring.
When should I seek urgent care for Crohn's disease?
Seek urgent care for severe or worsening abdominal pain, repeated vomiting, a swollen abdomen, being unable to pass stool or wind, heavy bleeding, a high fever or a painful swelling near the anus.
