Are abdominal pain and bloating signs of an unhealthy gut?
Abdominal pain and bloating are a sign that your gut needs attention, but on their own they say little about how "unhealthy" that gut is. If you have prolonged or severe complaints, first have other causes ruled out and seek guidance on diet or treatment.
Abdominal pain and bloating are everyday complaints that occur as a standalone symptom in 3.5% of the population. In people with irritable bowel syndrome or functional dyspepsia, those figures rise to more than 50%. These complaints do not automatically mean that something is structurally wrong with your gut, but they are not nothing either.
Irritable bowel syndrome is the best-known cause. It affects 5 to 10% of the population and is characterised by abdominal pain, bloating and an altered bowel pattern. The diagnosis is made on the basis of symptoms and by ruling out other diseases, not because a measurable abnormality can be found in the gut. Yet something is genuinely going on: an oversensitive gut, a disrupted coordination between the abdominal muscles and the diaphragm, poor digestion of certain carbohydrates, changes in gut bacteria and a slowed intestinal transit all play a role. Which mechanism predominates in any given person is not always possible to determine.
Experts emphasise that with persistent complaints you should always rule out physically demonstrable causes, such as inflammatory bowel disease or coeliac disease. If there are no alarm signals, extensive endoscopic or laboratory investigations are generally not necessary.
What you should not do is follow a strict diet on your own. Many people attribute their complaints to food intolerances and eliminate all sorts of food groups. This rarely resolves the complaints and carries the risk of nutritional deficiencies and further disruption of the gut bacteria. Guidance is genuinely useful in that situation. Which approach works varies from person to person: a low-FODMAP diet, probiotics, gut-relaxing or gut-motility-stimulating medications, or in the case of IBS even cognitive behavioural therapy and hypnotherapy can all help, but no single treatment works for everyone.
This answer is based on several review articles and guideline publications on functional bowel complaints, in particular on irritable bowel syndrome and functional bloating. The evidence on mechanisms and treatments is reasonably well supported by larger studies, but for specific treatment options the effects vary considerably from person to person and by no means all interventions have been compared in large independent studies.
What are the signs that your gut flora is out of balance?
There are several recognisable signals, of which abdominal complaints such as persistent pain, diarrhoea, or constipation are the best supported. If you experience prolonged bowel complaints after a course of antibiotics or an infection, discuss this with your GP.
Can an unhealthy gut contribute to skin problems such as acne or eczema?
A disrupted gut microbiome is associated with acne and eczema, although that association has not yet been proven to be cause and effect. Eating more fibre and plant-based foods is a sensible first step; for targeted probiotics the evidence is still too mixed for a clear recommendation.
Can stress really make your gut sick?
Stress really can make your gut sick: from abdominal pain and altered bowel habits to an increased risk of IBS and stomach complaints. If you suffer from chronic gut symptoms, stress is a factor worth discussing with your doctor.
Is my gut flora linked to being overweight?
Your gut microbiome is probably linked to excess weight through multiple mechanisms, but a proven causal relationship in humans is still lacking. A varied diet that supports your gut microbiome is worthwhile, but specific supplements for weight loss have not yet been proven effective.
Does bone broth help your gut health?
The individual components of bone broth, such as certain amino acids, show favourable effects on the intestinal wall in laboratory and animal research, but bone broth as a product has never been tested in a clinical trial. You can drink it without concern, but do not count on it as a proven remedy for gut problems.
Can a disrupted gut microbiome weaken your immune system?
A disrupted gut microbiome demonstrably dysregulates your immune system and increases the risk of chronic inflammation. Eating fermented foods is the best-supported way to do something about it.
