Let’s decode your gut
How many times do you typically have a bowel movement per day / per week?
๐ก Normal range: 3 times a day to 3 times a week. Outside this range consistently is a clinical signal.
How often do you need to strain or push hard during a bowel movement?
๐ก Straining on more than 25% of occasions is one of the Rome IV criteria for functional constipation.
After a bowel movement, do you often feel like you haven’t fully emptied?
๐ก This is called “sensation of incomplete evacuation” โ a key Rome IV diagnostic marker for IBS and functional constipation.
How often do you experience each of these symptoms?
๐ก Tap each symptom to mark how frequently it affects you โ this patterns your gut disorder profile.
Which best describes how you eat your meals?
๐ก Ideal: 20 minutes minimum per meal. It takes 20 min for satiety signals from the gut to reach the brain.
Where and how are you usually sitting when you eat?
How well do you chew your food before swallowing?
๐ก Research suggests 20โ30 chews per mouthful for optimal digestion and satiety signalling. Saliva contains enzymes (amylase, lipase) that begin digestion.
Do you drink large amounts of water or cold drinks during meals?
๐ก Drinking large amounts of fluid during meals can dilute stomach acid (HCl) and digestive enzymes, impairing protein digestion and triggering bloating.
How much time typically passes between your last meal and going to bed?
๐ก Eating within 2 hours of sleep impairs gastric emptying and is strongly linked to acid reflux, poor sleep quality, and disrupted gut motility overnight.
Do you notice your gut symptoms get worse during periods of stress, anxiety, or emotional upset?
๐ก The gut has its own nervous system (enteric nervous system โ 500 million neurons). Stress directly alters gut motility, stomach acid, and microbiome composition via the gut-brain axis.
Are you currently taking or regularly using any of the following? (Select the closest match)
๐ก Several common medications directly impact gut health โ antacids reduce stomach acid needed for digestion; NSAIDs damage the gut lining; PPIs alter microbiome composition.

Tick every different plant food you’ve eaten in the last 7 days. Vegetables, fruits, legumes, grains, nuts, seeds, and fresh herbs all count โ but not the same food twice. Target: 30+

plants counted this week
Keep ticking โ every plant feeds a different microbe
How often do you eat fermented or probiotic-rich foods? (dahi/curd, chaas, idli, dosa, kanji, fermented pickle, kefir)
๐ก A Stanford study (Sonnenburg & Gardner, 2021, Cell) found that a high-fermented-food diet steadily increased microbiota diversity and decreased inflammatory markers over 10 weeks.
Have you taken antibiotics in the past 12 months?
๐ก Antibiotics can wipe out up to 90% of gut bacteria diversity. Recovery takes 1โ2 months for most species, but some strains may not return without probiotic support.

The science powering this tool
Bristol Stool Form Scale: Lewis & Heaton (1997), Scand J Gastroenterol โ validated measure of intestinal transit time, gold standard in clinical GI research.
Rome IV Criteria: Rome Foundation (2016) โ internationally validated symptom-based diagnostic criteria for functional GI disorders including IBS, functional constipation, and functional dyspepsia.
Gut Microbiome Diversity: McDonald et al. (2018), American Gut Project (n=10,000+) โ 30+ plant foods/week associated with significantly greater microbiome diversity and beneficial SCFA-producing bacteria.
Fermented Foods: Wastyk, Sonnenburg et al. (2021), Cell โ high-fermented-food diet increased microbiota diversity and decreased inflammatory markers over 17 weeks.
