The short explanation
Occasional antacid use for indigestion is generally fine, but needing it almost every day for months is a sign that it is worth seeing a doctor. Antacids relieve symptoms but do not treat the underlying cause. Ongoing heaviness after meals can come from reflux, H. pylori infection, gallstones, stomach ulcers, or functional indigestion, and each is managed differently. Some antacids contain substances such as aluminium, magnesium or calcium that can cause constipation or loose stools, and long-term regular use may affect other medicines or, in people with kidney problems, mineral balance. A doctor can check what is causing your symptoms and suggest a better plan.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Large or late meals, oily food, tea or coffee, stress and weight around the waist commonly cause heaviness after meals.
- Warning signs such as difficulty swallowing, weight loss, vomiting, black stools or anaemia need prompt tests.
- Keeping a note of which meals bring on symptoms can help your doctor.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This cannot tell you what is causing your symptoms or whether your antacid use is harming you. A doctor's review is needed.
