Crohn's Disease and UK Military Service: Discharge Information

Crohn's disease is a chronic inflammatory bowel disease that can impact fitness for military service due to its unpredictable course, need for ongoing treatment, and potential for complications.

Assessment Process

The British Army evaluates each case individually via a Medical Board comprising senior medical officers. Factors considered:

• Disease severity, extent, and phenotype (inflammatory, stricturing, penetrating)
• Current symptom control and medication requirements (immunomodulators, biologics, steroids)
• History of surgeries, strictures, fistulae, or abscesses
• Nutritional status and growth (if young recruit)
• Ability to deploy to environments without specialized gastroenterology care
• Risk of flare under operational stress

Possible Outcomes

• Fit for service: Mild, well-controlled disease on minimal therapy (e.g., mesalamine only), no recent flares, no structural complications.
• Temporarily unfit (downgraded): Recent flare, medication change, or pending investigation – reassessed later.
• Permanently unfit (discharged): Moderate-severe disease, need for biologics/steroids, surgical history, or high deployment risk.

Key Points

• Decision is made by Medical Board; recommendation reviewed by chain of command.
• Personnel have right to appeal via Service Complaints process.
• Discharge is medical, not disciplinary; resettlement support provided.
• Civilian equality law does not override military medical standards for deployability.

Serving personnel with Crohn's should engage early with their medical officer and request a Medical Board if their condition changes.
