- Treated online: Yes, usually. Video assessment, with a prescription when appropriate.
- Most constipation improves with fluids, fibre and the right laxative used short term; a persistent new change in bowel habit needs assessment, not just more laxatives.
- Anywhere from three bowel movements a day to three a week can be normal; change from your own pattern matters more.
- Opioid painkillers, including everyday codeine combinations, constipate almost everyone who takes them regularly, and iron tablets are close behind.
- Call 112 if you also feel faint, confused, or are in overwhelming pain.
See a doctor in person, rather than booking a video appointment, if constipation comes with severe constant abdominal pain, repeated vomiting, or a swollen tense belly with no stool or wind passing: that pattern suggests a blockage, and it is an emergency, so call 112. Blood mixed into your stool, black tar-like stools, unexplained weight loss, or a new persistent change in bowel habit, especially from about 50 onwards, needs prompt in-person tests.
Can an online doctor treat constipation?
Yes, in most cases. Mobi Doctor, an online healthcare service with licensed doctors, assesses constipation by video: your normal pattern, what changed, your diet, fluids and medicines, and any warning signs. The doctor then treats the cause and, where needed, prescribes laxatives in the guideline order. Red flags, and suspected blockage or impaction, are routed to in-person care instead, and prescribing rules vary by country.
Constipation is genuinely well suited to video care because the assessment is history: what changed, when, and why. The consultation earns its keep in two places most self-treatment misses: spotting the medicine or condition quietly causing the problem, and giving you a stepwise plan with an exit, so laxatives are a bridge back to normal rather than a permanent fixture. The honest limit is examination: where impaction, severe pain or a mass is suspected, hands are needed before stronger treatment is safe.

How an online consultation helps with constipation
medicines are one of the most common triggers, opioid painkillers, iron tablets, some antidepressants and blood pressure treatments among them, alongside low fibre, low fluids, thyroid problems and routine change. Treating the cause beats stacking laxatives on top of it.
which type to start with, what to add if it fails, how long to use it and how to step off, instead of the pharmacy roulette most people are left to play alone.
bleeding, weight loss, anaemia symptoms and a genuinely changed habit are asked about directly, and investigated promptly when present, not explained away.
you leave with doses, a review date and a step-down strategy, because the goal is a bowel that works without help, wherever that is achievable.
What the doctor checks in an online constipation consultation
Constipation means different things to different people, so the consultation starts by pinning yours down. The doctor will typically work through:
- What constipated means for you: fewer bowel movements than your normal, hard or pellet-like stools, straining, pain, or the feeling of incomplete emptying. Each points the plan differently.
- The timeline: lifelong tendency, weeks of change, or sudden arrest; and what changed around the same time, such as diet, travel, illness, or a new medicine.
- Your full medicine list: including over-the-counter codeine-containing painkillers, iron, and antacids, which are frequent and fixable culprits.[1]
- Diet, fluids and movement: fibre in practice rather than in theory, how much you actually drink, and how much of the day is sedentary.
- Routine and behaviour: ignored urges, rushed mornings, unfamiliar toilets when travelling, and shift work, all of which suppress the bowel reflexes.
- Screening for causes: tiredness, cold intolerance and weight gain (thyroid), thirst and urination (diabetes), and neurological symptoms, which redirect the work-up.
- Red flags: blood in or on the stool, black stools, unexplained weight loss, anaemia symptoms, severe pain, vomiting, and family history of bowel cancer.[2]
- Straining mechanics: prolonged straining or needing manual pressure suggests a pelvic floor problem, which laxatives alone will not fix and which may need in-person assessment.
- Pregnancy: common, hormone-driven, and treated with its own preferred options.
What causes constipation?
Constipation happens when stool moves too slowly through the colon or is difficult to pass: too little fibre or fluid, inactivity, ignoring the urge, routine change and travel are everyday drivers. Medicines are a major cause, opioids especially, and underactive thyroid, diabetes and irritable bowel syndrome contribute; often no single cause is found.[1]
Everyday drivers
The colon is a creature of habit. It responds to food volume and fibre, to hydration, to movement, and above all to routine: the strongest natural trigger for a bowel movement is the reflex that follows a meal, particularly breakfast. Skip breakfast, sit all day, sip too little and suppress the urge because the moment is inconvenient, and the system slows within days. Travel compresses all of these at once, which is why constipation is the travelling companion nobody advertises.
Medicines and conditions
Opioid painkillers, including everyday codeine combinations, constipate almost everyone who takes them regularly; iron tablets, some antidepressants, some blood pressure medicines and calcium- or aluminium-based antacids are close behind.[1] Among conditions, an underactive thyroid, diabetes and neurological disease all slow the bowel, and irritable bowel syndrome includes a constipation-predominant form in which cramping, bloating and hard stools travel together; when aching in the lower abdomen dominates the picture, our colon pain page explains how doctors read it. Pregnancy slows the gut hormonally from early on. And in many people, particularly women, no cause is ever named: the bowel is simply slow, which is a real pattern that still responds to structured treatment.
Which laxative should I take first?
Guidelines suggest a stepwise order. Start with a bulk-forming laxative such as ispaghula while fixing fibre and fluids; add or switch to an osmotic laxative such as macrogol if stools stay hard; add a stimulant such as senna or bisacodyl if stools are soft but still difficult to pass. Use short courses and review.[1]
Some honesty about laxatives, because folklore runs both directions. They are not dangerous when used sensibly, and nobody should sit in discomfort out of vague fear of dependence. But the order matters (bulk needs fluid to work; osmotics soften; stimulants push), doses should be the lowest that works, and courses should have a review date, then a slow step-down rather than an abrupt stop. Long-term daily stimulant use without review is the pattern to avoid. Two groups are the exception, not the rule: people on ongoing opioids, and some older adults, genuinely need maintained laxatives, openly and under review, and that is good medicine rather than failure.
How can I control constipation without laxatives?
Routine does more than any supplement: sit on the toilet unhurried for a few minutes after breakfast, when the bowel reflex is strongest, and never suppress an urge you can answer. Raise your knees above hip level with a footstool, which straightens the anatomy and reduces straining. Build fibre up gradually, aiming at wholegrains, fruit, vegetables and pulses, with kiwifruit and prunes as pleasantly evidence-backed options, and drink enough that your urine runs pale. Walk daily.[4] Given two to four weeks, this combination controls constipation for many people without a single tablet, and it remains the foundation even when laxatives are added.
When should I worry about constipation?
Worry when constipation is a genuine change that persists beyond about 4 weeks despite sensible measures, or arrives with blood in the stool, black stools, unexplained weight loss, anaemia symptoms such as unusual tiredness or breathlessness, or a family history of bowel cancer, particularly from about 50 onwards. That combination needs prompt in-person tests, not a stronger laxative.[2]
The emergency version is different and faster: constipation with severe constant pain, vomiting, and a swollen tense belly passing neither stool nor wind suggests obstruction, and impacted stool with overflow (unexpected leakage of loose stool around a blockage, common in older adults and easily mistaken for simple diarrhoea) also needs examination rather than anti-diarrhoeals, which make it worse. Both are in-person problems the same day.
Is my constipation suitable for online care?
Most constipation is, and the plan differs by pattern. Here is how doctors sort it.
Swipe sideways to compare →
| Constipation pattern | Likely first step | Suitable for online care? | When referral or in-person care is needed |
|---|---|---|---|
| Recent constipation after diet, travel or routine change | Fluids, fibre, movement and toilet routine; a bulk-forming laxative if needed[1] | Usually yes, often without a prescription | Not settling within about 2 weeks, or any red flag |
| Ongoing constipation in an otherwise well adult | Stepwise laxative plan with a review date and a step-down strategy | Usually yes | No response to combined laxatives at proper doses, or new red flags |
| Constipation on opioids, iron or other constipating medicines | Medication review plus a suitable laxative from the start | Usually yes | Where the underlying prescription needs an in-person review to change |
| Constipation alternating with diarrhoea, with bloating and cramps | Assessment for irritable bowel syndrome[3] | Usually yes | Bleeding, weight loss, night-time symptoms, or onset from about 50 onwards |
| Constipation with bleeding, weight loss, vomiting or severe pain | In-person assessment and tests[2] | No | Same day for pain and vomiting; call 112 for a suspected blockage |
Availability of individual medicines and who may prescribe them vary by country; your doctor confirms what applies where you are.

What you can do yourself
Start with the mechanics: gradual fibre increase with plenty of fluid (fibre without water can worsen things), a daily walk, the after-breakfast toilet routine, and a footstool to improve position. Answer urges promptly. Check your own shelf for quiet saboteurs, especially codeine-containing painkillers taken for something else. Bulk-forming laxatives such as ispaghula are available from pharmacies and suit mild, recent constipation; give any change a fair two weeks before judging it. What does not help: dramatic colon-cleanse products and prolonged straining, which achieves little beyond haemorrhoids.
Prescription treatment
A prescription is never issued without a consultation. After assessment, the doctor works the ladder with you: macrogol-type osmotic laxatives to soften and get things moving, a stimulant added short term where stools are soft but stuck, and doses adjusted rather than multiplied.[1] Opioid-induced constipation gets a laxative planned alongside the painkiller, not after it fails, and where an opioid or another constipating medicine should change, the doctor coordinates rather than overrides your regular prescriber. For chronic constipation that has genuinely failed properly dosed laxatives, further options such as prucalopride exist; they belong after honest failure of the basics, sometimes with specialist input, and who may start them varies by country.[5] In pregnancy, bulk-forming and osmotic laxatives are the usual choices, with stimulants used more cautiously, decided case by case. Suspected impaction is examined in person before stronger treatment, because the wrong medicine at the wrong moment makes it worse.
When we treat constipation online, and when we refer you
We treat online: recent and ongoing constipation in adults, with a stepwise plan and review; medicine-related constipation, including on opioids and iron; constipation-predominant irritable bowel patterns; pregnancy constipation with its preferred options; and step-down planning for people stuck on daily laxatives who want a route off.
We refer or redirect you: suspected obstruction or faecal impaction, in person the same day, with 112 for the full-blown pattern; the red-flag cluster, bleeding, black stools, weight loss, anaemia symptoms, or a persistent new change in habit especially from about 50 onwards, promptly for examination and bowel tests with a referral letter written in the consultation;[2] suspected pelvic floor dysfunction, for in-person assessment and, where available, specialist physiotherapy; and children with significant constipation, whose treatment follows its own pathway and doses and is best managed by a doctor who can examine them.
When to get in-person care
Go to emergency care now if constipation comes with severe constant abdominal pain, repeated vomiting, or a swollen tense belly with no stool or wind passing: that suggests a bowel blockage. Call 112 if you also feel faint, confused, or are in overwhelming pain. Blood in the stool with light-headedness, or black tar-like stools, needs urgent in-person assessment the same day.

Frequently asked questions about constipation
Can an online doctor prescribe laxatives in Europe?
Yes, after a video assessment, the doctor can prescribe laxatives in the guideline order, from bulk-forming and macrogol-type osmotics to short-term stimulants, matched to your pattern. A prescription is never issued without a consultation, the prescription can go to a pharmacy near you in most EU countries, and prescribing rules vary by country.
How much does an online constipation consultation cost?
A video consultation costs €47. The exact price is shown before payment, and there is no subscription. Appointments run daily from 7am to 11pm, often the same day.
How can I control constipation without laxatives?
Build a routine the bowel can rely on: unhurried toilet time after breakfast, urges answered promptly, a footstool to raise your knees, fibre increased gradually with plenty of fluid, and a daily walk. Kiwifruit and prunes are simple evidence-backed additions. Given 2–4 weeks, this controls constipation for many people without any tablet.
How long is too long to go without a bowel movement?
There is no single number: anywhere from three times a day to three times a week can be normal, and change from your own pattern matters more than any rule. As a guide, going beyond about a week despite fluids, fibre and a suitable laxative deserves a review, and sooner with pain, vomiting, bleeding or a swollen belly.
Are laxatives safe to use long term?
Used correctly, with review, yes for some people: those on ongoing opioids and some older adults genuinely need them, and that is appropriate treatment. What is worth avoiding is unreviewed daily stimulant use for years by default. The better pattern is the lowest effective dose, a planned step-down when the bowel recovers, and a doctor involved when stepping down fails.
Is constipation a sign of bowel cancer?
On its own, usually not; constipation is extremely common and overwhelmingly benign. The picture changes when it is a genuine persistent change lasting over 4 weeks, or arrives with bleeding, black stools, unexplained weight loss, anaemia symptoms or a strong family history, particularly from about 50 onwards. That combination needs prompt tests, not a stronger laxative.
What helps constipation in pregnancy?
Fluids, gradual fibre and gentle activity are the first steps for constipation in pregnancy, which is very common, driven by hormones that slow the gut plus iron supplements. Where a laxative is needed, bulk-forming and macrogol-type osmotic options are the usual first choices in pregnancy, with stimulants used more cautiously and case by case. A doctor confirms what suits your situation and stage.
