Study Notes
Gastrointestinal Tract Anatomy
- The lower oesophageal sphincter (LOS) regulates the movement of food from the oesophagus to the stomach.
- The stomach secretes hydrochloric acid (HCl), approximately 2L per day.
- HCl aids digestion, kills bacteria and creates the ideal pH for the digestive enzyme, pepsin.
Dyspepsia
- "Bad digestion"
- No universally agreed upon definition.
- Describes symptoms of the upper gastrointestinal tract and is a complex group of symptoms rather than a single diagnosis.
Dyspepsia Symptoms
- Upper abdominal pain or discomfort
- Heartburn, gastric acid reflux
- Heaviness or ache
- Fullness, abdominal bloating, belching
- Flatulence
- Nausea, vomiting, early satiety
- Symptoms may be associated with eating
Dyspepsia Causes
- 80% of cases are functional dyspepsia (unknown origin)
- Gastro-oesophageal reflux disease (GORD)
- 20% of cases are peptic ulcer, duodenal ulcer or erosive oesophagitis
- Oesophageal and gastric cancers are rare causes (less than 1%.)
Dyspepsia Red Flags
- Patients over 55 years old who experience dyspepsia for the first time
- Patients experiencing weight loss
- Patients on long term PPI therapy (need to see a specialist.)
- Patients on medications known to worsen dyspepsia symptoms or cause bleeding (e.g. NSAIDs)
Dyspepsia Non-Pharmacological Treatment Options
- Weight management
- Exercise
- Improve posture
- Avoid tight fitting clothes
- Avoid smoking and alcohol
- Raise the head of the bed (not with extra pillows)
- Avoid potential triggers: coffee, chocolate, fatty/spicy foods or eating late at night
- Smaller, more frequent meals
- Getting adequate sleep and reducing stress can improve digestive symptoms
- Identify potentially exacerbating medications.
Dyspepsia Pharmacological Treatment Options: Antacids
- Aluminium hydroxide, magnesium carbonate, magnesium trisilicate, calcium carbonate, sodium bicarbonate.
- Aluminium or magnesium salts are preferred.
- Neutralise stomach acid by balancing pH.
- Provide symptomatic relief.
- Taken as needed (PRN) when symptoms are expected (e.g. 1 hour after a meal and/or prior to bedtime.)
- Only for ages 12 and above with maximum use of 2 weeks. Seek medical advice if symptoms persist after 7 days.
Antacids Adverse Effects
- Diarrhoea (Mg)
- Constipation (Al or Ca)
- Belching
- Sodium content should be considered for all products.
Antacid Advice
- Safe in pregnancy and breastfeeding.
- Do not take at the same time as other medications as absorption may be impaired.
- Medications to avoid with antacids: iron supplements, calcium supplements, antibiotics, levothyroxine, phenytoin, digoxin, aspirin, thiazide diuretics, bisphosphonates, tuberculosis therapy, HIV therapy.
Dyspepsia Pharmacological Treatment Options: Simeticone
- Antifoaming agent to relieve trapped wind.
- Causes gas bubbles to coalesce and disperse, releasing trapped wind.
- Added to antacids to relieve flatulence.
- Safe in pregnancy and breastfeeding.
- Maximum use is 2 weeks. Seek medical advice if symptoms persist after 7 days.
Dyspepsia Pharmacological Treatment Options: Alginates
- Sodium Alginate (e.g., Gaviscon)
- Forms a protective layer on the stomach and oesophageal walls, creating a mechanical barrier.
- Increases viscosity of stomach contents.
- Safe in pregnancy and breastfeeding if clinically indicated.
- Seek medical advice if symptoms do not improve after 7 days.
- Adults and children over 12.
- Take after meals and at bedtime.
Dyspepsia Pharmacological Treatment Options: H2 (Histamine Receptor 2) Antagonists
- Inhibit H2 receptor on parietal cells, competitively reducing the production of acid.
- Short term relief of heartburn, indigestion (dyspepsia) and excess acid.
- Prevents symptoms associated with meals, including nocturnal symptoms.
H2 Antagonist Advice
- Twice daily dosing: before meals and at bedtime.
- Maximum treatment duration is 2 weeks OTC.
- Avoid for children under 16 years.
- Avoid in pregnancy and breastfeeding unless prescribed by a doctor.
- May interact with other medications (WWHAM), consider antacid interactions.
Dyspepsia Pharmacological Treatment Options: Proton Pump Inhibitors (PPIs)
- Esomeprazole, Omeprazole, Pantoprazole.
- Available OTC.
- Block the "proton pump" to suppress acid secretion, regardless of the stimulus.
- Provide prolonged acid suppression, generally dosed once daily.
- Take at least 30 minutes before food, ideally before breakfast.
- Enteric coated, meaning they should be taken on an empty stomach.
- Most OTC products are for over 18 (exception: Losec control does not have an age limit.)
PPI Advice
- Takes 3 days for maximum relief.
- Refer to GP if symptoms are not relieved or persist beyond the licence duration.
- Drug interactions include clopidogrel, some Hep C/HIV antivirals and pH dependent absorption drugs.
OTC PPIs in Pregnancy and Breastfeeding
- Antacids and Alginates can be provided OTC.
- H2 antagonists and PPIs require medical advice from a doctor.
