Bloating is one word for at least six different mechanisms, and they need opposite fixes. Gas from fermentation, food sitting in the stomach, a transit problem, fluid being mistaken for gas, swallowed air, or a gut that is simply more sensitive than average. This works out which one you have, mostly from when the symptoms start.
People use "bloated" for very different sensations, and the sensation tells you where the problem is. Select everything that fits.
Six mechanisms sit at different points along the digestive tract, and each one takes a different amount of time to produce a symptom. Immediate discomfort fits swallowed air or delayed gastric emptying, 30 to 90 minutes fits the small bowel, and 2 to 4 hours fits colonic fermentation of unabsorbed carbohydrate. Nobody asks for this detail in a normal food diary, which is why elimination diets so often run for years without resolving anything.
Most people who react to a protein shake assume lactose and switch products at random. The tool instead totals your actual daily lactose load from your whey type, scoop count and other dairy, and checks it against the roughly 12 g single-dose threshold where symptoms typically become prominent. If isolate is the shake in question, the load usually sits an order of magnitude below that line, which redirects the investigation toward milk protein or additives instead. Worth reading alongside the Calorie & Macro Calculator if a shake swap changes your daily protein target.
Each mechanism is scored against its own evidence ceiling rather than competing against the others for a single percentage, so fermentation and constipation, for example, can both come back strongly supported at the same time. That is the usual reason people conclude nothing works: they fix one mechanism, see partial improvement, and assume the fix failed when it actually solved half the problem.
Where a symptom sits in the digestive tract is written into how long it takes to appear. Symptoms right after eating point at swallowed air or the stomach itself, 30 to 90 minutes points at the small bowel, 2 to 4 hours points at colonic fermentation, and all-day distension that worsens through the day points at transit rather than any single meal. Almost nobody is asked this, and it separates the mechanisms better than a food diary does.
Usually not, and the tool runs the numbers to check. Whey isolate carries roughly 0.3 g of lactose per scoop, an order of magnitude below the 12 g threshold where symptoms typically become prominent. Concentrate carries roughly 2 g per scoop, which can add up. If you react to isolate specifically, lactose is almost certainly not the mechanism, and the investigation should move to milk protein sensitivity or the sweeteners and gums in the powder instead.
Yes, and the tool scores each of the six mechanisms against its own evidence threshold rather than forcing them to compete for one percentage. It is common for two, such as fermentation and constipation, to both come back strongly supported. When that happens the tool tells you to work on one at a time so you know which change is actually responsible for any improvement.
Coeliac blood tests look for antibodies your body only produces while you are still eating gluten. Removing it first before testing makes the result come back negative regardless of whether you have the condition, and the only way to test properly afterwards is to reintroduce gluten for six weeks. If coeliac disease is a possibility at all, the tool flags this before it becomes a lost diagnosis.
Not usually. Delayed gastric emptying is a primary mechanism of how GLP-1 medications work, not a side effect to eliminate through food changes. The fullness, reflux and constipation that come with it typically respond to meal structure, such as smaller and more frequent meals, and tend to settle within a couple of weeks at each dose.
