1.Must include one or more of the following:

People with mild to moderate severity of dyspepsia will be identified with the Short Form Leeds Dyspepsia Questionnaire. This consists of eight items that assess the presence and severity of dyspepsia by measuring the frequency and severity of upper abdominal pain/discomfort, heartburn, regurgitation and nausea. Possible scores range from 0 to 32 with higher values corresponding with increasing severity of dyspepsia. A score of 1 to 23 indicates mild to moderate dyspepsia symptoms.
- Inability to give informed consent
- Severe functional dyspepsia, defined by a score of 23 or higher from the Short Form Leeds Dyspepsia Questionnaire
- Taken antibiotics within the month before starting the study
- Use of certain prescribed medication or recreational drugs. People taking Proton Pump Inhibitors, H2-receptor antagonists, antacids, mucosal protectants, prokinetics, antidepressant drugs if they were prescribed solely for controlling dyspepsia symptoms, anticholinergic agents, cholinergic agents, and over-the-counter herbal remedies used to treat dyspepsia symptoms will be required to stop taking four weeks prior to the start of the study
