- Treated online: Yes, for reviews, flare recognition and renewals of established treatment. Maintenance medicines such as mesalazine or an established immunosuppressant can be repeated after a video review; biologics, new immunosuppressants and steroid courses for flares are specialist decisions made in person.
- What it is: patchy, full-thickness inflammation anywhere from mouth to anus, most often the last part of the small intestine; Crohn's disease affects about 1 in 300 people in Europe, usually starts between 15 and 35, and runs in families.
- Flare signs: stool frequency rising over days to weeks, returning pain, blood or mucus, deep fatigue, low-grade fever or slipping weight; an infection can mimic a flare, so a stool test for calprotectin and infection is often the first step.
- Smoking: the strongest modifiable factor in Crohn's disease: smokers flare about twice as often, respond less well to treatment and need surgery more often, and stopping measurably improves the course of the disease.
- Outlook: about 3 in 4 people with Crohn's disease need an operation at some point in their lives, but with modern biologic treatment most reach and hold remission, with healed bowel and a full working life.
- Emergency: call 112 or go to emergency care for severe abdominal pain with repeated vomiting and a swollen belly, a rigid or very tender abdomen, heavy rectal bleeding, high fever with feeling very unwell, or signs of serious dehydration.
Do not book a video appointment for a possible emergency: severe abdominal pain with repeated vomiting and a swollen or bloated belly (possible obstruction), a rigid or very tender abdomen, heavy rectal bleeding, high fever with feeling very unwell, or signs of serious dehydration. Call 112 or go to emergency care. A painful swelling beside the anus with fever may be an abscess and needs same-day in-person care.
Can an online doctor treat Crohn’s disease?
Not as the main treatment, and it is important to say so plainly. Crohn’s disease is a lifelong inflammatory bowel disease managed by gastroenterology teams. What a licensed doctor on Mobi Doctor offers is support between specialist appointments: early flare recognition, repeat prescriptions of established suitable medication where appropriate, and fast gastroenterology referral. Biologic medicines are never started or managed online.
That division of labour is not a limitation to apologise for; it is how good Crohn’s care works everywhere. Specialists make the diagnosis, choose and monitor the disease-modifying treatment, and scope and scan at the right intervals. The gaps people actually fall into are between those moments: symptoms creeping up and no appointment for months, a move to a new country with no local team yet, a repeat prescription running out mid-travel. Those gaps are exactly where a video doctor is useful.
How an online consultation helps with Crohn’s disease
- Flare recognition against your baseline: the doctor works through your stool frequency, pain, fatigue, weight and temperature compared with your normal, the structured check that separates a genuine flare from an infection or a bad week, and tells you how urgently to act.
- Bridging support between teams: new to a country, waiting for your first local gastroenterology appointment, or travelling across Europe: the doctor reviews you, documents your history properly, and keeps suitable treatment from lapsing where appropriate.
- A referral letter that opens doors: a clear letter naming your diagnosis, current medication, red flags and what is being asked for gets you into gastroenterology faster than arriving unannounced.
- The practical extras handled: smoking cessation support (the single strongest modifiable factor in Crohn’s), pain relief that avoids anti-inflammatory painkillers, hydration planning in diarrhoea phases, and a check that monitoring blood tests are not quietly overdue.[1]
What the doctor checks in an online Crohn’s consultation
A Crohn’s consultation is anchored to your history, because your baseline is the measuring stick. The doctor will typically go through:
- Your diagnosis story: when and where Crohn’s was confirmed, which parts of the bowel are affected, and any previous surgery, strictures or fistulas.
- Your specialist team and last review: who monitors you, when you were last seen, and when your next scope, scan or clinic is due.
- Your exact current medicines: maintenance treatment, doses, who prescribes and who monitors bloods, and whether anything has lapsed or run short.
- Now versus baseline: stool frequency and consistency, blood or mucus, abdominal pain, fatigue, fevers, appetite and weight over the last weeks.
- The obstruction screen: crampy pain after meals, bloating, loud gurgling and vomiting, particularly if you have known strictures.
- Perianal symptoms: pain, swelling, discharge or fever around the anus, which need in-person assessment quickly.
- Beyond the gut: joint pains, eye redness or pain, mouth ulcers and skin changes, the extra-intestinal signals that inflammation is active.
- Triggers and confounders: recent gut infections, courses of antibiotics, anti-inflammatory painkillers, missed doses, and smoking status.[2]
- Red flags: the emergency patterns in the triage box, screened directly every time.
What is Crohn’s disease?
Crohn’s disease is a long-term inflammatory bowel disease in which the immune system inflames the digestive tract, most often the end of the small intestine and the start of the colon, in patches that can affect the full thickness of the bowel wall. It typically flares and settles in cycles, is most often diagnosed in young adults, and is managed rather than cured.[2]
The cause is a mix of genetic susceptibility, immune behaviour and environment; it is nobody’s fault and no diet caused it. Typical symptoms include diarrhoea lasting weeks, crampy abdominal pain, weight loss, fatigue and sometimes mouth ulcers or perianal problems.[4] Because inflammation can reach beyond the gut, joints, eyes and skin can be involved too. Smoking is the clearest modifiable aggravator: smokers with Crohn’s flare more, respond less well to treatment and need surgery more often, which is why stopping is treated as part of the disease treatment itself, not general lifestyle advice.[1][2]
Crohn’s disease or ulcerative colitis?
Both are forms of inflammatory bowel disease, and the distinction shapes treatment: Crohn’s can affect any part of the digestive tract in patches and full thickness, while ulcerative colitis inflames the colon’s lining continuously from the rectum upwards. Symptoms overlap, and the two are separated by colonoscopy and biopsies, not by symptom lists. The inflammatory bowel disease overview compares the two conditions side by side.
How do I know if I am having a Crohn’s flare?
A flare usually means a sustained shift from your own baseline: stool frequency climbing over days to weeks, returning abdominal pain, blood or mucus, fatigue out of proportion, low-grade fevers, mouth ulcers or slipping weight. Compare against your normal, not a textbook. New severe pain, repeated vomiting or high fever is not a flare to monitor; it is urgent.
Three look-alikes are worth knowing because they change the response. Gut infections, including traveller’s diarrhoea and norovirus, can mimic a flare and sometimes trigger one, which is why stool testing is often the first step rather than an immediate escalation of treatment. Bile-related diarrhoea after previous bowel surgery has its own specific treatment. And many people with Crohn’s also have an irritable-bowel-type overlap, where cramping and urgency persist even when inflammation markers are quiet. A structured review, sometimes with a stool inflammation test (faecal calprotectin) arranged through local services where available, separates these far better than guesswork, and separating them matters: treating a flare that is actually an infection helps nobody.[2]
Can an online doctor prescribe my Crohn’s medication?
Sometimes, for repeats of established treatment. Where you are stable on a suitable maintenance medicine and simply need continuity, the doctor can review you and prescribe a repeat where appropriate. Biologics such as adalimumab or infliximab, and new courses of immunosuppressants or steroids, are specialist decisions and are never initiated or managed online.[5]
The reasons are worth spelling out, because they protect you. Biologics and immunosuppressants need structured blood monitoring, infection screening and specialist supply chains; steroid courses for flares need an in-person assessment of severity first and a specialist plan behind them, because repeated steroid courses are themselves a signal that maintenance treatment needs changing.[1] What an online doctor can responsibly do is keep appropriate established treatment from lapsing, make sure monitoring is booked rather than forgotten, treat around the edges (hydration, suitable pain relief, skin and mouth care), and escalate to your team, in writing, the moment the picture says escalate. One more honest rule: never stop maintenance medication because you feel well without a specialist conversation; stopping is the most predictable flare trigger there is.

| Situation | Likely first step | Suitable for online care? | When referral or in-person care is needed |
|---|---|---|---|
| Stable on maintenance treatment, running low while travelling or between teams | Review and a repeat prescription where appropriate | Often yes | Where monitoring bloods are overdue, or the medicine is specialist-supply only |
| Early flare symptoms against your baseline, no severe features | Structured review, stool testing where available, safety-netting, and contact with your IBD team[2] | Yes, for assessment and bridging | Worsening despite the plan, or any severe feature appearing |
| Possible new Crohn’s: diarrhoea over 4 weeks, weight loss, blood, fatigue | Assessment and fast referral to gastroenterology for tests[1] | Assessment yes; diagnosis needs colonoscopy in person | Promptly by design: early diagnosis changes outcomes |
| Biologic dosing, monitoring blood tests, or treatment escalation decisions | Your specialist IBD team[3] | No | Always specialist-managed; the doctor helps you reach them faster |
| Severe pain, repeated vomiting, swollen belly, high fever or heavy bleeding | Emergency care | No | Call 112 or go to emergency care now |

What you can do yourself
The highest-value self-care in Crohn’s is specific. Stop smoking, with help if needed: it is the strongest modifiable factor in the disease’s course.[1] Prefer paracetamol over ibuprofen and other anti-inflammatory painkillers, which are associated with flares. Keep hydration deliberate during diarrhoea phases. There is no single proven Crohn’s diet, so be sceptical of anyone selling one; what helps is a symptom diary, professional dietitian input where strictures require texture changes, and eating enough, because under-eating quietly worsens fatigue and weight loss. Keep vaccinations, dental care and bone health on the agenda with your team, and treat the mental load as real: living with an unpredictable disease is tiring, and support helps.
Prescription treatment
A prescription is never issued without a consultation, and in Crohn’s disease the prescribing map is layered by design. Flares are typically settled with steroid courses chosen and supervised through in-person and specialist assessment. Maintenance usually means immunomodulators such as azathioprine or methotrexate, with scheduled blood monitoring, or biologic medicines supplied and reviewed through hospital IBD teams.[1][3] Online, the appropriate role is repeats of established suitable medicines after review, supportive treatments (anti-diarrhoeals used cautiously and never in a severe flare, vitamin B12 and iron correction where deficiency is documented), and coordination: making sure the right prescriber does the right prescribing, on time.
When online help with Crohn’s disease is enough, and when you need in-person care
Handled online: flare recognition and early action plans; bridging reviews and repeat prescriptions where appropriate for people between specialist teams, relocating or travelling in Europe; fast, well-documented gastroenterology referrals, including for suspected new Crohn’s; supportive care around pain relief, hydration and deficiency correction; and smoking cessation as part of disease care.
In-person care: suspected obstruction, abscess, heavy bleeding or a severe flare, to emergency care immediately with 112 named on the call; perianal pain and swelling with fever, to same-day in-person care; all biologic and immunosuppressant initiation, dose changes and monitoring, to your IBD team, always;[3] colonoscopy and imaging decisions, to gastroenterology; and pregnancy planning with Crohn’s, to specialist care early, because medication needs reviewing before conception, not after. Where you have no team yet, the referral letter from the consultation is how you get one.
When to get in-person care
Go to emergency care now for severe abdominal pain with repeated vomiting and a swollen belly, a rigid or very tender abdomen, heavy rectal bleeding, high fever with shivering, or signs of serious dehydration such as drowsiness or passing little urine. If you feel faint or confused, call 112 immediately. A hot painful swelling beside the anus with fever needs same-day assessment.

Frequently asked questions about Crohn’s disease
What is Crohn's disease, and what causes it?
Crohn's disease is a lifelong inflammatory bowel disease in which the immune system attacks the lining and wall of the digestive tract in patches, most often the end of the small intestine and the start of the colon. The cause is a mix of inherited susceptibility, an over-active immune response to gut bacteria and environmental triggers; smoking, a low-fibre diet and childhood antibiotics raise the risk. Stress and diet alone do not cause it.
What are the symptoms of Crohn's disease?
Crohn's disease causes diarrhoea lasting weeks, sometimes with blood or mucus, cramping abdominal pain often in the lower right, weight loss, loss of appetite, deep fatigue, low-grade fevers, mouth ulcers and anaemia, and in some people painful skin swellings, joint pain, sore red eyes or abscesses and fistulas around the anus. Symptoms come in flares with quieter periods between, and children may grow slowly.
Can an online doctor prescribe my Crohn's medication in Europe?
For repeats of established, suitable maintenance treatment such as mesalazine or an immunosuppressant you are stable on, often yes, after a video review and where appropriate, with the prescription sent to a pharmacy near you. Biologics, immunosuppressant initiation and steroid courses for Crohn's flares are specialist decisions and are never started or managed online, and a prescription is never issued without a consultation.
How do I know if my symptoms are a Crohn's flare?
Measure against your own baseline: stool frequency rising over days to weeks, returning pain, blood or mucus, deep fatigue, low-grade fevers or slipping weight suggest a Crohn's flare. Infections, including after antibiotics, can mimic one, so stool testing is often the first step. Severe pain, vomiting, a swollen belly, heavy bleeding or high fever mean emergency care rather than waiting for a specialist appointment.
Is Crohn's disease the same as ulcerative colitis?
No. Both are inflammatory bowel diseases, but Crohn's can affect any part of the digestive tract in patches and through the full bowel wall, causing strictures, abscesses and fistulas, while ulcerative colitis affects only the lining of the colon continuously from the rectum. They are distinguished by colonoscopy, biopsies and scans, share many treatments, and in about 1 in 10 people the type is unclear at first.
Can Crohn's disease be cured?
No. Crohn's disease is a lifelong condition, and surgery removes damaged bowel without removing the tendency. What modern treatment achieves for most people is long remission: quiet disease, healed bowel and a full life, maintained by ongoing specialist care and, where prescribed, maintenance medication. Stopping treatment because you feel well is the commonest route back to a flare.
What should I do if I run out of my Crohn's medication abroad?
Act before the last tablet: a video consultation can review your treatment and, where appropriate, prescribe a repeat of an established suitable medicine to a pharmacy near you. Specialist-supplied treatments such as biologics cannot be replaced this way; for those, contact your own IBD team or the nearest hospital gastroenterology unit, and carry a treatment summary when you travel with Crohn's disease.
Does smoking really make Crohn's worse?
Yes, clearly. Smokers with Crohn's disease flare about twice as often, respond less well to several treatments, and are more likely to need surgery and to relapse after it; stopping measurably improves the course of the disease within a year. It is the single most effective thing within your own control, and the doctor can prescribe or arrange stop-smoking support alongside your IBD care.
How long does a Crohn's flare last?
A Crohn's flare treated promptly usually settles within two to eight weeks, with steroids or a change in maintenance treatment started by the specialist team; untreated flares can grind on for months and cause strictures and abscesses. Between flares, remission can last months or years, and about half of people have a mild course overall. Fatigue often lags behind the bowel symptoms by weeks.
What can I do myself to manage Crohn's disease?
Take maintenance medication every day even when well, stop smoking, keep a symptom and stool diary so a flare is caught early, eat a varied diet and avoid only the foods that reliably upset you, drink enough, keep vaccinations up to date as advised, protect bone health with calcium, vitamin D and exercise, and tell the doctor about any new medicine, because anti-inflammatory painkillers and some antibiotics can trigger a flare of Crohn's disease.
Can Crohn's disease be prevented, or its flares reduced?
Crohn's disease cannot be prevented, but flares can be reduced: not smoking, taking maintenance treatment reliably, treating gut infections early, avoiding anti-inflammatory painkillers such as ibuprofen, managing stress and sleep, keeping weight and nutrition stable, and attending monitoring blood tests and scopes so the specialist can adjust treatment before a flare takes hold. Regular reviews are the prevention.
What complications can Crohn's disease cause?
Untreated or severe Crohn's disease can cause strictures that block the bowel, abscesses and fistulas around the anus or between organs, anaemia, vitamin B12 and iron deficiency, osteoporosis, gallstones and kidney stones, and after many years a raised risk of bowel cancer, which is why surveillance colonoscopy is offered. Inflammation elsewhere, in the joints, skin and eyes, flares with the gut and settles with treatment.
Is Crohn's disease different in pregnancy, in children or in older people?
In pregnancy, Crohn's disease in remission usually stays quiet and most medicines, including biologics, are continued because an untreated flare harms the baby more than the treatment; conception is best planned in remission with the IBD team. In children, Crohn's affects growth and is managed by paediatric gastroenterology, and Mobi Doctor sees adults only. In older people, Crohn's is often milder but medicines need more monitoring.
