GutLoop Knowledge Base

Knowledge base

Get to know the microbiome. Understand your biology. Make more informed decisions. A place you can enter with a specific problem or just out of curiosity — articles, learning materials, videos and the science behind it, written to say what we know and, honestly, what we don’t yet.

Health and the microbiome

What brings you to GutLoop?

Every topic from the homepage carousel has its article here. We talk about associations and areas to support — not about treatment.

  • All (12)
  • Digestion and gut
  • Weight and metabolism
  • Energy, sleep, mood
  • Immunity and skin
  • Women’s health
Weight struggles

Microbiome and body weight — what do we really know?

You eat well, exercise, try one diet after another, and yet the scales don’t move or the weight comes back after a few months? Body weight does not depend only on how much you eat and exercise.

Digestive problems

Microbiome and digestion — where do bloating, gas and constipation come from?

Bloating after meals? Gas? Constipation or diarrhoea? Digestive problems are among the most common gut complaints, and they can have many causes.

Low energy

Constant tiredness — what might the microbiome have to do with energy?

You sleep enough, eat reasonably well, and still struggle to get going in the morning? Tiredness can have many causes — and there is no single “low energy test”.

Immunity

Microbiome and immunity — what happens in the gut?

The gut is one of the most important points of contact between the body and the outside world. The microbiome and the immune system do not work independently — they communicate constantly.

Mood and stress

Gut and brain — can the microbiome affect how you feel?

Do you notice that when you are stressed your stomach plays up? Or the other way round — gut problems affect your mood? It may not be a coincidence.

Skin health

Gut microbiome and skin — what is the gut–skin axis?

Acne, redness, dry skin or recurring skin problems? Skin care is not only about what you put on your face.

Endometriosis

Endometriosis and the microbiome — what we know and what we don’t yet

Endometriosis is a chronic oestrogen-dependent disease whose mechanisms are still not fully understood. A growing number of studies also look at the gut microbiome and its possible link.

Metabolism and blood sugar

Microbiome and metabolism — what do bacteria and blood sugar have in common?

Why does one person feel great after the same meal while another’s glucose shoots up? The body’s response to food is highly individual.

Sleep and recovery

Can the microbiome influence sleep?

You sleep long enough and still feel tired in the morning? More and more research points to a complex relationship between sleep, circadian rhythm and the gut microbiome.

After antibiotics

What happens to the microbiome after antibiotic treatment?

An antibiotic acts on the bacteria causing an infection. But its effect is not always limited to them — treatment can temporarily change the composition, diversity and function of the microbiome.

IBS / irritable bowel

IBS and the microbiome — do bacteria matter?

Bloating. Abdominal pain. Gas. Diarrhoea or constipation. Irritable bowel syndrome is a common gut disorder whose mechanism cannot be reduced to a single cause.

Prevention

Know your biology — why observe your microbiome?

Why test your microbiome if nothing is wrong? It is a bit like getting to know your body before a specific problem appears.

Our science

How do we know what we write?

Every article in the Knowledge Base is based on research reviews and guidelines (incl. WHO) and checked against what science actually confirms. We don’t write that the microbiome “cures” — we write about observed associations and what still needs research.

GUT·DIET·MAP: a knowledge graph linking microbiome, diet and health

A description of the sources, structure and update process of the map of biological relationships.

The sources our articles rely on

WHO healthy-diet guidelines, research reviews on the microbiome and body weight, the PREDICT study (postprandial responses).

Results and interpretation

How to read the GutLoop report?

What diversity means, what “lower / typical / higher abundance” is and why we don’t label bacteria as good or bad.

AI and personalisation

How does GutLoop tailor recommendations?

GUT·DIET·MAP, data about you and your goals, the role of the AI Dietitian — and where personalisation ends and a conversation with a specialist begins.

Diet and the microbiome

Fibre, fermentation, plant diversity

Which foods support different microbiome functions, what WHO says about 25 g of fibre a day and why there is no single “microbiome diet”.

From question to decision

Don’t guess. Check.

The Knowledge Base is the first step. If you want to see how it looks for you, a microbiome test will show your own profile — and the app will help turn it into everyday decisions. Tested in Poland, 16S rRNA sequencing, data processed under GDPR.
