- Wavelike course: periods of exacerbation alternate with remission, and it is almost impossible to predict when the next deterioration will occur.
- Inflammation of the entire thickness of the wall: affected areas of the bowel alternate with healthy tissue, which disrupts the absorption of nutrients.
- Prolonged diarrhoea and pain: loose stools persist for weeks, and the pain is more often felt in the lower right abdomen or around the navel.
- Urgent reasons: severe abdominal pain, persistent vomiting, dehydration and bleeding require calling an ambulance.
- Follow-up with a gastroenterologist: visits are needed even when you feel well, since changes in the bowel wall accumulate unnoticed.
What is Crohn's disease
Crohn's disease is a long-term inflammatory disease of the digestive tract, in which various parts of it can be affected. The disease runs in waves: periods of flare-up alternate with periods of remission, and the person requires constant medical supervision.
What happens in the body
Crohn's disease affects the wall of the digestive tract, causing persistent inflammation in it. The person's immune system begins to react to their own intestinal microflora as if it were a foreign irritant. Because of this, an inflammatory reaction is constantly maintained in the tissues of the bowel, and it does not subside on its own. The inflammation can involve various parts of the digestive tube, sometimes interrupted by areas of healthy tissue. The wall of the bowel gradually swells, thickens and loses its ability to absorb nutrients normally. The person notices this through changes in how they feel, but it is not always possible to link the complaints to the workings of the bowel straight away. When such signs appear, it is important not to put off a visit to the doctor and not to try to explain the condition away as tiredness or a chance upset.
What causes it to develop
- Hereditary predisposition: the risk is higher if close relatives have had inflammatory bowel diseases, so family history is taken into account when talking to the doctor.
- Peculiarities of how the immune system works: the body's defence cells begin to respond unusually to its own intestinal microflora, triggering long-term inflammation in the wall of the organ.
- Influence of environmental factors: living conditions, diet and external influences can become the background against which the disease manifests in a predisposed person.
- Disruption of the composition of the intestinal microflora: a change in the balance of bacteria in the bowel affects the workings of the immune system and can maintain an inflammatory reaction in the tissues.
- Smoking as an aggravating factor: tobacco smoke makes the course of the disease more severe and increases the frequency of flare-ups, so giving up smoking remains a sensible step.
Who encounters this more often
Crohn's disease is more often detected in people of young and middle age, although it is possible to fall ill at any period of life. Heredity plays a noticeable role: if close relatives have the disease, the likelihood increases. Living and dietary conditions also have a certain significance, as do harmful habits, above all smoking. The condition is found more often in city dwellers than in rural residents, which is linked to the characteristics of the environment and lifestyle. Men and women fall ill with roughly equal frequency, with no noticeable predominance by sex. Doctors cannot yet name the exact reason why the disease manifests in one person and not in another. When alarming signs appear, it is sensible to discuss family history with a specialist rather than look for explanations on your own.
What symptoms can occur?
Crohn's disease manifests differently depending on which parts of the digestive tract are involved. Outside a flare-up, a person may feel reasonably well, but the condition requires ongoing monitoring by a specialist.
How it is noticed at the very beginning
At the outset, Crohn's disease often makes itself known through prolonged diarrhoea, which a person attributes to accidental food poisoning or nervous tension. Gradually, abdominal pain joins the loose stools, most often in the lower right part or around the navel. Many put such sensations down to stale food, overwork or ordinary indigestion and do not go to a doctor. Weight decreases imperceptibly: a person does not change their diet, but clothes become looser and strength runs out faster than usual. Fatigue and weakness increase insidiously, and these too are easily mistaken for the aftermath of a busy week. Sometimes blood appears in the stool, and painful sensations arise in the anal area. If diarrhoea persists for weeks and weakness does not pass after rest, it is worth booking an appointment with a gastroenterologist for an examination.
Symptoms that occur most often
- Prolonged diarrhoea: loose stools persist for weeks and are not linked to a one-off dietary lapse, which points to inflammation in the bowel.
- Abdominal pain: most often felt in the lower right or around the navel, may be cramping and worsens after eating.
- Weight loss without an obvious cause: body weight falls despite normal eating, because nutrients are absorbed less well by the inflamed intestinal wall.
- Fatigue and weakness: persist even after a full night's sleep and interfere with everyday tasks, reflecting general exhaustion of the body.
- Blood in the stool: noticeable on the paper or in the stool itself and requires medical assessment, as it indicates damage to the mucosa.
- Painful sensations in the anal area: associated with fissures or inflammation, which makes going to the toilet agonising.
When to seek urgent help
Examinations and tests
Examination for Crohn's disease is carried out in stages: first the doctor talks to the patient and examines them, then prescribes tests and instrumental investigations. The aim is to confirm intestinal inflammation and rule out other diseases with similar manifestations.
How the examination begins
The examination begins with a conversation and examination by a doctor, who clarifies the complaints, how long they have been present and their connection with meals. The doctor asks about the nature of the pain, stools, episodes of bleeding and unplanned weight loss. Separately, it is established whether close relatives have had similar conditions and what operations the person has undergone. Then the specialist examines the abdomen, assesses it on palpation and checks the anal area. Such an examination helps to notice fissures, fistulas and other local changes that the person sometimes does not mention. Based on the results of the conversation and examination, the doctor decides which investigations are needed first. The exact set of investigations depends on the complaints, so one should not undergo everything in a row on one's own.
What is prescribed and what it shows
What is worth preparing for the appointment
- Discharge summaries: take all medical documents describing past visits, hospitalisations and operations so that the doctor sees the full picture.
- Test results: collect previous blood and stool tests, even if they were done long ago — this helps to assess changes.
- List of complaints: write down in advance when the pain, changes in stools and weight loss appeared, so as not to forget anything at the appointment.
- Observations about stools: note the frequency, consistency and admixtures of blood over the last few days — these details are important for the doctor.
- Questions for the doctor: formulate in advance what you want to clarify about the further steps of the examination, so that the appointment is productive.
Which doctor should I see?
This section explains which specialist to consult for Crohn's disease, what happens at the first appointment and what areas of care it consists of. It also shows separately which part of the result depends on the regularity of follow-up with a doctor.
Which specialist manages this condition
Crohn's disease is managed by a gastroenterologist, and when the rectum and the anal area are affected, a proctologist is also involved. The gastroenterologist provides the main follow-up, assesses complaints, well-being and general condition, while the proctologist examines local manifestations on the part of the bowel. If there is no specialist nearby, you can start with a general practitioner at your place of residence, who will refer you to the right doctor. At the first appointment, the doctor asks in detail about complaints, how long they have been present and any changes, and collects information about past conditions and family history. Then he examines the patient and determines which tests are needed to clarify the picture. Based on the results of the appointment, the doctor formulates a care plan and explains how often to come for follow-up. This approach helps avoid wasting time and ensures follow-up is consistent rather than occasional.
What treatment consists of
- Selection of therapy by the doctor: the specialist selects care individually for the specific picture and regularly adjusts it as changes occur.
- Follow-up and monitoring of the condition: scheduled visits and examinations allow changes to be noticed in time and the approach to be changed without waiting for deterioration.
- Adjustment of diet and lifestyle: eating habits and daily routine affect well-being, so they are discussed together with the doctor.
- Surgery for certain indications: surgical intervention is not always considered, but only when there are grounds for it.
- Psychological support and working on quality of life: a long-term condition affects mood and everyday affairs, and this side should also be kept in view.
What depends on the patient themselves
The regularity of follow-up with a doctor largely determines how smoothly Crohn's disease progresses and how often periods of good well-being occur. It is not yet possible to completely rid a person of the disease, but modern therapy makes it possible to reduce inflammation and relieve symptoms. When a person comes for an appointment as planned, and not only when things get worse, the doctor notices changes earlier and manages to adjust care. Missed visits and delayed consultations lead to changes accumulating unnoticed and making themselves known only when they are already severe. It is equally important to tell the doctor honestly about your well-being, diet and everyday difficulties, because this determines how accurately care is selected. Keeping records of your condition helps you not to forget anything at the appointment and to see the whole picture. It is worth preparing questions for the doctor in advance and not putting them off until the next visit. Calmly and consistently following the doctor's plan gives more than rare consultations at the time of an exacerbation.
What helps prevent an exacerbation?
There is no specific prevention that is guaranteed to prevent flare-ups of Crohn's disease. What is meant here are everyday measures that help you encounter worsening less often and feel better.
What is changed in habits
Giving up smoking is among the habits that most noticeably affect the course of Crohn's disease. Nicotine maintains inflammation in the intestinal wall, so smokers have flare-ups more often and they are more severe. Following the recommended diet helps avoid irritating the bowel with coarse fibre, hot spices and fatty food. Sufficient rest and reducing stress are important because chronic tension and lack of sleep affect how you feel and how the bowel works. Seeking help promptly when things worsen allows you not to let the process run on and to bring the condition back under control more quickly. Regular follow-up with a doctor makes it possible to notice problems earlier than they become obvious. If a person notices a link between a particular food or situation and worsening, this should be told to the doctor. Keeping a simple diary of how you feel helps to see such links and discuss them at an appointment.
What should be kept under control
- How you feel: note changes in the abdomen, stools and general condition so as to notice the start of a flare-up in time.
- Diet: stick to the recommended diet and watch how the body responds to individual foods.
- Rest and stress: get enough sleep and reduce the load, since fatigue and tension worsen the course of the disease.
- Smoking: giving up cigarettes noticeably reduces the frequency of flare-ups, so this should be kept in mind at all times.
- Visits to the doctor: come to appointments at the appointed times, even if you currently feel quite well.
How often to see the doctor
Regular visits to the doctor are needed even when you feel well and nothing is troubling you. Crohn's disease can run unnoticed, and changes in the intestinal wall sometimes accumulate without obvious symptoms. At an appointment the doctor assesses the general condition, asks about stools, appetite and weight, and clarifies how the recommended diet is tolerated. If new complaints or worsening appear, the visit should not be put off until the planned date. Such monitoring allows recommendations to be adjusted in time and the situation not to be brought to a severe flare-up. Missed appointments often lead to worsening being noticed late, when it is harder to cope with. Keep in touch with the doctor and report any changes so that treatment remains timely.
What is worth remembering
A discussion about Crohn's disease comes down to a few conclusions that are useful to keep in mind after becoming familiar with the topic. They concern not individual signs, but the very approach to this condition.
Main conclusions
Crohn's disease is a condition that develops in waves: calm periods are replaced by flare-ups, and it is almost impossible to predict in advance when the next one will occur. Paying attention to your own body helps to notice the onset of a flare-up: a change in your usual well-being and stools is a reason not to wait, but to consult a doctor. Examination in Crohn's disease is not a one-off event, but a regular process, since the condition of the inner wall of the bowel changes over time. Treatment is selected individually, and what helped one person may not suit another. Many people with Crohn's disease live full lives, work and travel, if they keep the condition under supervision. The mistake most often made is trying to endure unpleasant sensations and putting off a visit to a specialist until the last moment. The support in decision-making is not someone else's experience from conversations, but your own observation plan agreed with a doctor.
