Reflux is usually a mechanical problem: the valve between stomach and oesophagus relaxes when it should not, so normal stomach acid reaches tissue that has no defence against it. Suppressing acid relieves the symptom without changing the mechanism, which is why it recurs on stopping.
The valve, not the acid
Stomach acid is strongly acidic by design — it is needed to break down protein and to absorb iron, calcium and vitamin B12. The stomach lining is built for it. The oesophagus is not.
The lower oesophageal sphincter is the valve between them. Reflux happens when that valve relaxes at the wrong moment, or when pressure in the stomach pushes contents past it. In most people the acid is normal. Its location is not.
Is this what is happening to you?The two-minute check further down asks four questions and shows the result immediately. No email, no call.
Take the 2-minute checkWhat relaxes the valve or raises the pressure
Once the mechanism is clear, the list of triggers stops looking arbitrary.
- Large meals — volume raises stomach pressure directly
- Lying down within three hours of eating — removes gravity from the equation
- High-fat meals — slow stomach emptying, so the load sits longer
- Coffee, alcohol, chocolate and mint — all relax the valve
- Tight waistbands — raise abdominal pressure mechanically
- Abdominal weight — the same effect, continuously
2-minute check
What is going on with your digestion?
Four questions, answered in about a minute.
When does discomfort appear?
Any bloating through the day?
Has your bowel habit changed?
How often do you take an antacid or laxative?
This sounds occasional rather than established
Meal timing, fibre and fluid usually settle it.
A pattern is forming
Regular antacid or laxative use is worth reviewing — it manages the symptom rather than the cause.
This fits an established pattern
Worth proper assessment rather than continued self-medication, particularly if sleep is affected.
This check is an indication, not a diagnosis. It does not replace medical advice.
The antacid cycle
Acid-suppressing medicines work and they have a proper place. The difficulty is that long-term use does nothing about the valve, so symptoms return when the medicine stops — sometimes more sharply, as acid production rebounds.
Prolonged suppression also reduces absorption of vitamin B12, iron, calcium and magnesium, because that absorption depends on stomach acid. Someone taking a daily antacid for years may develop deficiencies that then present as fatigue.
None of that is an argument for stopping a prescribed medicine, which is a decision for the doctor who prescribed it. It is an argument for addressing the mechanism alongside.
What to change first
Three changes carry most of the benefit: finish eating three hours before lying down, reduce meal size and eat more frequently, and raise the head of the bed by fifteen centimetres if symptoms are worse at night. The last one is unglamorous and works better than most people expect.
Identify your own triggers by observation rather than by adopting a general list. Trigger foods vary considerably between individuals and a long list of unnecessary restrictions is its own problem.
In short
Questions we are asked
Should I stop my antacid?
Not on our advice. Long-term acid suppression is worth reviewing with the doctor who prescribed it, particularly regarding vitamin B12 and iron. Addressing the mechanism alongside is what may make that conversation possible.
Is milk good for acidity?
It gives brief relief and the fat content can worsen symptoms later by slowing stomach emptying. Cold milk helps some people in the moment; it is not a solution.
