What should you know about food intolerance medication?

A food intolerance is different from an immune food allergy. Some medicines can help with a specific digestive response or symptom, while others may be unsuitable if the cause has not been established. Medicines do not make every food safe, and a product that helps one person may not help another.

Bloating or diarrhoea can have causes unrelated to food. A clinician may therefore review your pattern, other symptoms, medicines, and diet before recommending an option. Testing can be useful when the history leaves the trigger uncertain.

Keep a short food-and-symptom record: note what you ate, the portion, when symptoms began, and what happened afterwards. Do not remove many foods for a long period without support, because restrictive eating can leave gaps in energy or nutrients. Ask whether a supervised elimination and reintroduction plan is appropriate.

Take only the medicine and dose recommended for your situation. Tell the clinician about pregnancy, long-term conditions, allergies, and all medicines or supplements. Nutrition counselling can help you replace a suspected trigger without unnecessarily narrowing your diet.

Arrange medical review if symptoms keep returning, disturb sleep, affect eating, or lead to weight change or dehydration. Seek urgent help for trouble breathing, swelling of the lips or tongue, faintness, severe weakness, blood in stool, or intense and worsening abdominal pain; these features need assessment rather than self-treatment.

Ask: Which symptom is this medicine intended to treat? What should I do if it does not help? Could another condition explain my symptoms? Do I need testing, and how can I keep my diet nutritionally adequate?
