Conditions
Type2Diabetes
A chronic metabolic condition where the body becomes resistant to insulin or does not produce enough, leading to elevated blood sugar levels. The most common form of diabetes, affecting over 1 million Australians.

Online care is not suitable for every situation. A doctor decides what fits after assessment.
Symptoms
CommonsymptomsofType2Diabetes
Symptoms can overlap across conditions. A doctor considers context, red flags, and whether remote review is appropriate.
Increased thirst and frequent urination
Fatigue and tiredness
Blurred vision
Slow-healing wounds
Frequent infections (thrush, urinary)
Tingling or numbness in hands/feet
Often no symptoms (detected on blood test)
Our Scope
Whereonlinereviewmayfit
Online review can help with some straightforward situations, but it is not a substitute for urgent care, physical examination, or ongoing GP management.
May fit online review
- Prescription renewals for diabetes medication (metformin, SGLT2 inhibitors, etc.)
- Medication review and dose adjustments
- Discussion of treatment options and new therapies
- Medical certificates for diabetes-related absences
- Referral to endocrinologist, diabetes educator, or dietitian
Needs in-person or urgent care
- Initial diabetes diagnosis and workup (requires in-person assessment and blood tests)
- Insulin initiation (requires in-person education and training)
- Diabetic foot assessment (requires physical examination)
- Diabetic eye screening (requires in-person retinal imaging)
Depending on your situation, an AHPRA-registered doctor may be able to issue a medical certificate or arrange a repeat prescription after reviewing your request online.

- 1You need a medication review or prescription renewal
- 2Blood sugar levels consistently above target despite treatment
- 3You want to discuss treatment options or changes
- 4You need a medical certificate related to diabetes management
- 5You are experiencing medication side effects
Seek emergency care if
- Blood sugar above 15 mmol/L with vomiting, confusion, or rapid breathing (diabetic ketoacidosis)
- Severe hypoglycaemia (blood sugar below 4 mmol/L) with confusion or loss of consciousness

Clinical Insight

Type 2 diabetes management has been transformed in the last decade. We have moved beyond simply lowering blood sugar to medications that also protect the heart and kidneys. SGLT2 inhibitors (empagliflozin, dapagliflozin) and GLP-1 receptor agonists (semaglutide, dulaglutide) have proven cardiovascular and renal benefits independent of their glucose-lowering effect. This means the choice of second-line medication now depends on whether a patient has cardiovascular disease or kidney disease, not just their HbA1c. Metformin remains the foundation of treatment -- it is effective, cheap, well-tolerated (after initial GI adjustment), and has decades of safety data. The biggest gap I see in diabetes care is not medication -- it is self-management education. Patients who work with a diabetes educator and accredited practising dietitian consistently achieve better outcomes than those managed by medication alone.
Treatment
TreatingType2Diabetes
Type 2 diabetes treatment follows a stepwise approach. Metformin is first-line alongside lifestyle modification. Second-line agents are now chosen based on cardiovascular and renal risk profile, not just glucose lowering. SGLT2 inhibitors and GLP-1 receptor agonists have proven benefits beyond blood sugar control.
Metformin
Diabex, Diaformin, Glucophage
Class:Biguanide
Typical dose:500mg twice daily initially, increasing to 1000mg twice daily
PBS:PBS listed as first-line therapy for type 2 diabetes
- First-line medication for almost all patients with type 2 diabetes
- Weight-neutral or slight weight loss -- does not cause hypoglycaemia alone
- GI side effects (nausea, diarrhoea) are common initially but settle over 2-4 weeks
- Take with food and start at low dose to minimise GI effects
Empagliflozin
Jardiance
Class:SGLT2 inhibitor
Typical dose:10-25mg once daily
PBS:PBS listed for type 2 diabetes with cardiovascular disease or additional risk factors
- Proven cardiovascular and kidney-protective benefits in landmark EMPA-REG trial
- Promotes weight loss of 2-3kg and modest blood pressure reduction
- Works by blocking glucose reabsorption in the kidneys (causes glucose in urine)
- Risk of genital thrush (especially in women) and urinary tract infections
Dulaglutide
Trulicity
Class:GLP-1 receptor agonist
Typical dose:1.5mg subcutaneous injection once weekly
PBS:PBS authority required for type 2 diabetes with inadequate control on other agents
- Once-weekly injection with significant HbA1c reduction and weight loss
- Proven cardiovascular benefit in the REWIND trial
- Nausea is common initially but usually settles over 4-8 weeks
- PBS authority approval required -- specific criteria must be met

Specialist referral: Referral to an endocrinologist or diabetes specialist is recommended if HbA1c remains above target despite combination oral therapy, if insulin initiation is needed, for type 1 diabetes or uncertain diagnosis, or for diabetes in pregnancy.
Type 2 Diabetes in Australia
Over 1.3 million Australians have type 2 diabetes, with approximately 45,000 new diagnoses per year
An additional 500,000 Australians have undiagnosed type 2 diabetes
Diabetes is the fastest-growing chronic condition in Australia
The annual cost of diabetes in Australia exceeds $17.6 billion (direct and indirect costs)
Recovery
Whattoexpect
Typical recovery timeline and return-to-work guidance for most patients.
Typical recovery
Type 2 diabetes is a chronic condition. Metformin reaches full effect in 2-4 weeks. HbA1c improvements are measured every 3 months. Lifestyle changes (diet, exercise, weight loss) can produce significant improvements within 3-6 months. Some patients achieve remission with substantial weight loss.
Return to work
Type 2 diabetes rarely prevents work. When starting new medication, GI side effects (metformin) or dizziness may affect the first 1-2 weeks. Hypoglycaemia risk is low with metformin alone but may occur with sulfonylureas or insulin.
When to reassess
HbA1c every 3 months when starting or changing treatment, then every 6 months when stable. Annual screening: kidney function, lipids, eye check, foot assessment. See a doctor if blood sugars are consistently above target or you experience medication side effects.
Self-Care
ManagingType2Diabetesathome
Evidence-based tips to support your recovery alongside medical treatment.
Monitor your blood sugar as directed -- knowing your numbers helps you make better food and activity choices
Aim for 150 minutes of moderate-intensity exercise per week -- even a daily 30-minute walk significantly improves insulin sensitivity
Focus on low-GI foods (whole grains, legumes, non-starchy vegetables) rather than eliminating all carbohydrates
Weight loss of 5-10% can dramatically improve blood sugar control -- and may reduce the need for medication
See a diabetes educator and dietitian -- they provide practical, personalised management that medication alone cannot
Check your feet daily for cuts, blisters, or changes -- diabetic foot complications are preventable with early detection
FAQ
CommonquestionsaboutType2Diabetes
Answers to the most common questions from patients.
Normal HbA1c is below 6.0% (42 mmol/mol). The general target for type 2 diabetes is below 7.0% (53 mmol/mol), though this may be individualised. HbA1c reflects your average blood sugar over the past 2-3 months.
Yes, if you have an established diagnosis and are on existing medication, our doctors can review your treatment and issue prescriptions via eScript. New diagnoses and insulin initiation require in-person assessment.
Significant weight loss (10-15% of body weight) can put type 2 diabetes into remission in some people, particularly if achieved early in the disease course. The DiRECT trial showed 46% remission at 1 year with intensive weight management. However, this is not achievable for everyone and ongoing monitoring is required.
GLP-1 receptor agonists (e.g. semaglutide, dulaglutide) are effective for blood sugar control and weight loss. They are PBS-listed for type 2 diabetes in certain circumstances. Availability in Australia has been affected by supply issues. Your doctor can discuss whether they are appropriate for you.
