Understanding Gastroparesis
Gastroparesis is a stomach motility disorder where the stomach takes too long to empty its contents into the small intestine. This delay in gastric emptying happens without any physical blockage, meaning food lingers in the stomach longer than it should.
As a result, patients can experience nausea, vomiting, bloating, early fullness, and unpredictable digestion. The condition can significantly affect quality of life, nutritional health, and social activities.
In Brisbane, patients with suspected gastroparesis are often first assessed by their GP or a gastroenterologist. For persistent or severe cases, referral to an experienced General Surgeon such as Dr. Goutham Sivasuthan ensures access to advanced investigations and, when needed, surgical treatments tailored to improve gastric emptying.
How the Stomach Normally Works
The stomach’s role is to grind food and mix it with digestive juices before sending it into the small intestine. This process is regulated by a coordinated series of muscle contractions and nerve signals.
In gastroparesis, the muscles of the stomach wall or the nerves controlling them (especially the vagus nerve) don’t function properly, slowing or even halting the emptying process.
Common Symptoms of Gastroparesis
Patients with gastroparesis may experience:
Nausea (often worse after meals)
Vomiting (sometimes hours after eating)
Early satiety – feeling full after only a few bites
Bloating and abdominal distension
Upper abdominal pain or discomfort
Fluctuating blood sugar levels (in diabetic patients)
Unintentional weight loss in chronic cases
These symptoms can range from mild to severe, sometimes leading to dehydration, malnutrition, and hospital admissions.
Causes and Risk Factors
Gastroparesis can result from several underlying conditions or events:
Diabetes – the most common cause (due to nerve damage from long-term high blood sugar)
Post-surgical – after certain abdominal or oesophageal operations
Viral infections – some cases follow viral illnesses
Autoimmune diseases – such as scleroderma
Neurological disorders – Parkinson’s disease, multiple sclerosis
Medication-related – drugs that slow gut motility (e.g., opioids, certain antidepressants)
Idiopathic gastroparesis – no clear cause found
Diagnosis – Investigation Pathway
Gastroparesis can mimic other digestive disorders, so accurate diagnosis is essential.
1. Detailed History and Examination
Dr. Sivasuthan will review your symptoms, onset, dietary patterns, medications, and any past medical or surgical history. Physical examination helps rule out other abdominal causes.
2. Blood Tests
Used to check for:
Electrolyte imbalances
Diabetes control (HbA1c)
Nutritional status (vitamin and mineral levels)
3. Endoscopy (Gastroscopy)
This allows direct visualisation of the stomach lining to rule out ulcers, inflammation, or structural blockages.
4. Gastric Emptying Study
The gold standard test for gastroparesis is a gastric emptying scintigraphy. This involves eating a small, harmless radioactive meal and taking scans over several hours to track how quickly food leaves the stomach.
When to See a Specialist in Brisbane
If you experience ongoing nausea, vomiting, bloating, or early fullness without a clear cause, it’s important to seek specialist input. Dr. Sivasuthan accepts referrals for:
Suspected delayed gastric emptying
Unexplained chronic nausea
Diabetic patients with worsening digestion problems
Post-surgical patients with new gastric motility issues
Abnormal results on gastric emptying tests
Treatment Options in Brisbane
Treatment is highly individualised, depending on severity and cause.
Lifestyle and Dietary Modifications
Small, frequent meals
Low-fat and low-fibre diets to ease gastric workload
Pureed or liquid-based meals for severe cases
Avoiding carbonated drinks and alcohol
Dietitian involvement is often essential for maintaining nutrition.
Medication
Medications aim to improve motility or relieve symptoms:
Prokinetic agents – metoclopramide, domperidone (stimulate stomach contractions)
Antiemetics – ondansetron, prochlorperazine (control nausea)
Erythromycin – sometimes used short-term for its motility effects
Medication choice depends on tolerance, side effects, and underlying conditions.
Endoscopic and Surgical Interventions
When conservative measures fail, surgical options may be considered:
1. Pyloroplasty
A procedure to widen the pylorus (stomach outlet) to help food pass more easily.
2. Feeding Tubes
For severe nutritional compromise, a jejunostomy feeding tube may be placed for direct small intestine feeding.
Dr. Sivasuthan works closely with gastroenterologists to determine the best timing and type of surgical intervention.
Gastroparesis vs Other Stomach Conditions
It’s important to distinguish gastroparesis from:
Peptic ulcer disease
Functional dyspepsia
Gastric outlet obstruction
Accurate diagnosis ensures patients receive targeted and effective treatment.
Living with Gastroparesis
Managing gastroparesis often involves long-term lifestyle adjustments. Many patients benefit from:
Keeping a food and symptom diary
Having a structured eating schedule
Seeking regular review with a multidisciplinary team (surgeon, gastroenterologist, dietitian)
Adjusting diabetic medications to accommodate altered digestion
