Indigestion, or dyspepsia, describes upper-digestive symptoms that often occur after eating or drinking. These include burning behind the breastbone, uncomfortable fullness, bloating, nausea, burping and the return of food or bitter fluid into the mouth. Stomach or back pain is not usually simple indigestion and may need a different assessment.
Acid reflux is a common cause. Symptoms may be aggravated by coffee, alcohol, chocolate, tomatoes, rich or spicy foods, smoking, excess weight, pregnancy, stress, anti-inflammatory painkillers or a hiatus hernia. Less commonly, persistent indigestion can be related to an ulcer or another medical condition.
Practical first steps
Eat at a comfortable pace and notice which foods reliably provoke symptoms. Smaller meals can reduce fullness, and avoiding food for three to four hours before bed may help night-time reflux. Raising the head and shoulders in bed can limit acid travelling upwards. Reducing fatty foods, alcohol, caffeine and smoking often helps more than an elaborate food-combining regime.
There is no physiological need for most people to separate protein and carbohydrate foods. Nor is it necessary to restrict fluid severely at meals; normal hydration does not “dilute” digestive secretions to a harmful degree. Castor-oil packs do not treat reflux or ulcer disease.
Recognising serious symptoms
A pharmacist can recommend antacids, alginates or acid-suppressing treatment where suitable. See a GP for recurrent symptoms, severe pain, unintentional weight loss, difficulty swallowing, repeated vomiting, iron-deficiency anaemia, a persistent abdominal lump, bloody vomit or blood in the stool.
Useful supplements
Supplements should be selected for the individual rather than used automatically. Product directions and advice from an appropriately qualified professional should take precedence over general information.
| Supplement | Effects |
|---|---|
| Peppermint-oil capsules | Intended to ease trapped wind and some forms of indigestion. |
| Zinc citrate | Supports enzymes and processes involved in normal stomach-acid production. |
| Broad-spectrum digestive enzymes | Supplies enzymes intended to assist digestion of proteins, fats and carbohydrates. |
| Aloe vera | Described as supporting intestinal microbial balance and general digestive health. |
| Spirulina powder | Provides concentrated nutrients and is described as supporting acid–alkaline balance. |
| Low-dose B-complex | Provides B vitamins involved in energy metabolism; the source highlights niacin and folate in relation to indigestion prevention. |
| Apple cider vinegar | Traditionally used to support gastric acidity and digestive secretions. |
Peppermint oil can worsen heartburn by relaxing the valve between stomach and oesophagus. Vinegar is acidic and can aggravate reflux or damage tooth enamel; it should never be used to “test” for low stomach acid. Digestive enzymes and aloe can cause adverse effects or interact with medicines.
The best approach is to identify the symptom pattern, address likely triggers and use appropriate short-term treatment while watching for warning signs. Recurrent indigestion deserves investigation rather than repeated self-treatment based on an assumed shortage of acid or enzymes.
