Bloating is one of those things that gets dismissed so easily. "It's normal." "Everyone has it." "Try cutting stress."
What I've found is that chronic bloating — the kind that shows up most days — is rarely just about the last thing you ate. It's usually a signal that something in your digestive system isn't working the way it should.
Bloating is a symptom, not a condition
The question worth asking isn't "what food caused this?" It's "why is my gut reacting this way?" Here's what I've learned tends to be underneath it:
Low stomach acid
Counterintuitive but really common, especially in women over 35. When stomach acid is low, food doesn't break down properly in the stomach. It sits, ferments, and produces gas. The bloating typically starts 30–60 minutes after eating and often comes with heartburn — which most people treat with acid reducers, potentially making the underlying problem worse.
Gut dysbiosis
An imbalance in gut bacteria. When certain bacteria overgrow, particularly in the small intestine (a condition called SIBO), they ferment carbohydrates and produce gas before your body can absorb them. This is the kind of bloating that seems to happen no matter what you eat.
Food intolerances
Different from allergies. Intolerances trigger a digestive response, not an immune one. The most common culprits: dairy, gluten, FODMAPs (fermentable carbohydrates in onions, garlic, beans, many fruits), and artificial sweeteners.
Slow motility
Food moving too slowly through the digestive tract. Common causes include low thyroid function, magnesium deficiency, dehydration, and chronic stress. Bloating appears later — often hours after eating or in the evening.
The pattern that actually matters
Single-day bloating after a specific food is useful. But what I've come to understand is that the pattern over time is what tells the real story — bloating that shows up on the same days, after the same food types, at the same time of day.
Common patterns worth tracking:
- Bloating within 30 minutes of eating — often low stomach acid
- Bloating 2–3 hours after eating — often gut bacteria or motility
- Bloating after dairy specifically — often lactose intolerance
- Bloating after wheat or gluten — worth discussing with your doctor
- Bloating every evening regardless of meals — often stress or slow motility
- Bloating that improves on fasting days — often SIBO or dysbiosis
What I'd push back on
Bloating is not normal. It is extremely common — but common and normal are not the same thing. "It's just IBS," "try cutting stress," "everyone has some bloating" — these responses aren't answers. They're the absence of one.
What to track and bring to an appointment
The most useful thing is logging consistently enough to see the pattern. Bring when the bloating happens relative to meals, which foods appeared on bloating days, whether it's accompanied by other symptoms, and how long it lasts. A documented pattern gets taken more seriously than a vague complaint.
What I'd ask at my next appointment
- Could low stomach acid be contributing?
- Is it worth testing for SIBO or gut dysbiosis?
- Could my thyroid be affecting my digestion?
- Does a food elimination trial make sense for my situation?
Your gut is telling you something. It's worth listening carefully enough to hear what it's actually saying.
