What should you know about digestive enzymes for gas?

Gas forms when swallowed air or gut bacteria contribute to intestinal contents being broken down. Bloating may occur with Food Intolerance, Lactose Intolerance, Irritable Bowel Syndrome, coeliac disease or Giardiasis. The timing of symptoms after meals, stool changes, travel history and unintended weight change can help a clinician decide what to investigate.

Commercial enzyme blends vary, and taking several products can make it hard to identify what helps. A response to a supplement does not confirm a diagnosis, and persistent symptoms deserve a broader assessment.

Eat slowly, chew thoroughly, limit fizzy drinks, and keep a short food-and-symptom diary. Gentle movement may help normal bowel activity. Avoid eliminating many foods at once, especially if you are losing weight or have a restricted diet. A doctor or dietitian can guide a structured trial and may recommend Nutrition Counselling when food choices have become confusing.

Arrange an appointment if bloating is new and persistent, progressively worsening, painful, associated with diarrhoea or constipation, or linked with weight loss, anaemia or blood in the stool. Seek urgent help for severe abdominal pain, repeated vomiting, a swollen rigid abdomen, inability to pass stool or gas, or faintness.

Ask whether your pattern suggests lactose intolerance, another food intolerance or a bowel condition; whether tests are needed; whether an enzyme trial is reasonable; and how to maintain balanced nutrition during any dietary change.
