A symptom diary that sits next to your plate
Symptoms on their own are hard to read. Bloating on Tuesday, a rough morning on Thursday — was it dinner, stress, a bad night's sleep? A symptom diary only starts answering that when it lives next to your food diary, with times attached to both. That's exactly how FoodTrigger AI is built.
What a good symptom diary captures
The symptom itself
Bloating, cramps, urgency, headache, fatigue, skin flare-ups — whatever you actually felt, in your own words or from a quick list.
When it started
Timing is the detail that does most of the detective work. A symptom logged at 7am points back at yesterday's meals, not this morning's coffee.
How strong it was
A simple severity note makes weeks comparable — you can see whether things are easing off or getting louder.
Sleep and stress
A rough night or a stressful week can stir up digestion on its own. Logging both keeps you from blaming food for a stress day.
What you ate and drank
Snap a photo of your plate and FoodTrigger AI suggests the ingredients, so this takes seconds instead of typing.
A food diary for diarrhea
Recurring diarrhea is one of the clearest cases for paired tracking, because the delay between eating and feeling can be a full day or more. The daily check-in logs urgency, cramps and the Bristol stool scale next to your meals, so looser mornings can be traced back to the meal window most likely involved. Read the full guide to keeping a food diary for diarrhea.
A food diary for food intolerance
Intolerances are sneaky because the reaction is often mild, delayed, and easy to blame on the wrong meal. Logging symptoms and ingredients together over a few weeks is how the same repeat offenders start showing themselves. Read the full guide to keeping a food diary for food intolerance.
How it works in FoodTrigger AI
Two daily habits, under a minute each: log your meals by photo, and do a quick check-in for symptoms, sleep and stress. Your pattern report lines everything up so you can see which ingredients kept appearing before difficult days. Your diary stays private — only you can see it.
Questions about keeping a symptom diary
What is a symptom diary?
It's a daily record of how you feel — symptoms, their timing, and what was going on around them. When it sits next to a food diary, it becomes a way to see which meals tend to come before difficult days, instead of guessing.
How is a symptom diary different from a food diary?
A food diary records what you ate. A symptom diary records what you felt. On their own, each is half the story — the useful part is having both with times attached, so delayed reactions stop looking random.
Can a symptom diary help with diarrhea or food intolerance?
It can help you spot your own repeats — for example, whether loose mornings tend to follow certain meals, or whether the same ingredients keep showing up before uncomfortable days. That's useful information for you and for any professional you talk to, but it isn't a diagnosis.
How long before patterns show up?
Most people need a few weeks of honest, consistent logging. One match is a coincidence; three is a lead worth testing or discussing with a professional.
When should I see a doctor?
Please see a healthcare professional for blood in your stool, ongoing diarrhea, severe pain, unexplained weight loss, or any change that worries you. A diary is a helpful companion to that conversation, not a substitute for it.
FoodTrigger AI is a tracking and pattern-identification tool. It does not diagnose, treat, cure, or prevent any medical condition and is not a substitute for professional medical advice, diagnosis, or treatment. Persistent symptoms, severe pain, blood in your stool, or unexplained weight loss deserve a healthcare professional.
