Careful analysis of symptoms and history is key to diagnosis

Diagnosis based on symptoms can be aided by a trial of treatment

Clear endoscopic abnormalities are found in <50% of patients

Treatment should start with a proton pump inhibitor (PPI)

Most patients will require long-term treatment; anti-reflux surgery may be as effective as PPIs, but is less predictable

Treatment options in GORDTreatment options in GORD• Simple (lifestyle) measures• Medical treatment

antacidsacid secretion suppressors -

PPI, H2RAs, H.p. erad. prokinetics

• Surgery (laparascopic)

Reduce weight

Stop smoking

Avoid reflux-promoting agents (e.g. alcohol, coffee, some foods) (not evidence based)

Elevate headof bed

Consider alternatives to

reflux-promoting drugs (e.g. theophylline, anticholinergics)

ModificationsModifications

Eat small meals,no late meals, reduce

fat

Lifestyle modificationsLifestyle modifications for the management of GORDfor the management of GORD

Lifestyle modificationsLifestyle modifications for the management of GORDfor the management of GORD

Increase the pH of gastric refluxate Reduce the erosive effect and hence reduce symptoms

Suitable for quick relief of mild symptoms

Most antacids are not suitable therapies for established GORD or oesophagitis

Less effective than H2RAs or PPIs for treatment of GORD

Adverse effects include: Accumulation in patients with renal impairment Milk-alkali syndrome with high doses Constipation Diarrhoea

AntacidsAntacids

AntacidsAntacids

Inhibit histamine stimulation of gastric parietal cell, resulting in reduced gastric acid secretion

Slower onset but longer duration of action than antacids

Cimetidine is associated with more drug interactions than other H2RAs, such as ranitidine

H2RAs are generally not as effective as PPIs for symptom relief or healing

ConclusionsConclusions

Long-term GORD can result in serious complications, which may prove fatal

Early treatment of GORD is associated with excellent outcomes

Late treatment is associated with an increased risk of complications and potentially poor outcomes

Early intervention relieves symptoms and helps prevent serious complications
