Ulcerative colitis usually presents between 15 and 35, and again after 55. Bloody diarrhoea, urgency, abdominal cramping — then a colonoscopy that makes the invisible visible. The diagnosis is difficult, but what comes next is more manageable than you might expect.
UC is a lifelong condition, but it is also one where modern treatment gives most people long, stable remissions. And uniquely among inflammatory bowel diseases, it has a definitive cure: colectomy, which eliminates the disease entirely if medical therapy eventually fails. That doesn't mean surgery is the goal — most people avoid it with good medical management. But knowing it's there changes the picture.
What to Do Right Now: Five Steps
Step 1 — Find out your disease extent and severity
Your gastroenterologist will have described your UC by extent (proctitis, left-sided, or extensive/pan-colitis) and severity (mild, moderate, or severe). These determine your treatment path.
Proctitis (rectum only) is the most limited form and often responds to rectal suppositories alone. Extensive colitis affecting the entire colon carries a higher risk of severe flares and hospitalisation. Know what you're managing.
Step 2 — Understand your first treatment: oral + rectal 5-ASA
For mild-moderate UC, 5-aminosalicylate (5-ASA / mesalamine) is the cornerstone treatment. This is a different starting point from Crohn's Disease, where 5-ASA is less effective.
You'll likely be on two 5-ASA preparations: oral tablets (Salofalk, Asacol, or generic mesalamine) to treat the whole colon, and rectal therapy (suppository for proctitis, enema for left-sided disease) for targeted action at the most inflamed section. Combination oral + rectal is more effective than either alone.
5-ASA therapy is fully CDL-funded. Cost: R700–900/month combined oral and rectal.
Step 3 — Register for CDL benefits
Contact your medical scheme and register UC as a CDL condition. This unlocks dedicated chronic benefits: your 5-ASA medication, azathioprine (if needed later), gastroenterologist visits, and monitoring colonoscopies.
Step 4 — Know when you need azathioprine — and prepare for it
If you have frequent relapses (two or more per year) or are steroid-dependent (can't come off prednisone without relapsing), azathioprine is the next step. It's a steroid-sparing maintenance agent that takes 3–6 months to work. It requires regular blood tests (FBC + LFTs) but is inexpensive (~R400/month) and CDL-funded.
TPMT enzyme activity should be tested before starting azathioprine — a genetic variant affects how your body processes thiopurines and can cause significant side effects at standard doses.
Step 5 — Understand the colectomy option — and decide how you feel about it
Surgery is not the goal, but it's important to know it exists. Total colectomy cures ulcerative colitis. If medical therapy ever fails and your quality of life is severely impaired, the surgical option eliminates the disease entirely. Many patients find it helpful — and grounding — to know that a definitive endpoint exists.
The surgery most commonly used is the ileal pouch-anal anastomosis (IPAA or J-pouch) — a procedure that removes the colon but preserves bowel function by creating a reservoir from the small intestine. It usually happens in two or three stages over several months.
Your Most Important Questions, Answered
Is UC ever "cured"? Medical therapy controls but does not cure UC. Colectomy — removal of the colon — does cure it, because UC is a disease of the colonic mucosa. Once the colon is gone, UC cannot recur. The IPAA procedure usually restores near-normal bowel function.
Will I be on medication forever? If you choose to avoid surgery (which most people do), yes — UC requires long-term maintenance therapy. 5-ASA or azathioprine for mild-moderate disease. Biologics for severe disease. Stopping maintenance medication dramatically increases relapse risk.
How often do I need colonoscopies? After 8–10 years of extensive UC, annual surveillance colonoscopies are recommended because long-standing colonic inflammation increases colorectal cancer risk. Your gastroenterologist will advise on timing based on your disease extent. Surveillance colonoscopy is CDL-funded.
What does my scheme cover? 5-ASA, azathioprine, gastroenterologist visits, and colonoscopy are CDL-funded. Biologics require exceptional needs authorisation. Colectomy is PMB-funded as a surgical procedure.
Can I have children? UC in remission does not significantly affect fertility. Discuss conception timing and medication safety with your gastroenterologist — most 5-ASA agents are safe in pregnancy; methotrexate and some biologics are not.
The Next Three Months
| Timeline | What Happens |
|---|---|
| Week 1–2 | 5-ASA initiated (oral + rectal). CDL registration submitted. Baseline CRP and FBC. |
| Month 1 | Steroid course (if needed for induction) started and tapered. Symptom response assessed. |
| Month 2 | Gastroenterologist review. Disease activity score. 5-ASA dose adjustment if needed. |
| Month 3 | First formal assessment of remission. Azathioprine discussed if 5-ASA is insufficient or steroid-dependence present. |
Your Scheme Coverage for UC
5-ASA, AZA, and gastroenterologist visits are fully CDL-funded. The critical scheme variables: biologic formulary (infliximab biosimilar CT-P13 as first-line?) and colorectal surgery network for eventual colectomy if needed. Surveillance colonoscopy coverage is also a key variable — confirm your scheme funds annual colonoscopy for longstanding extensive UC.
