Type 2 diabetes: what are my treatment options?

Newly told you have type 2 diabetes — or not yet on top of it? See the starting roads Australian GPs actually choose between, and the questions that decide which one is yours.

Prepare for your GP · general information, not a recommendation

Where you're at

Tell me where you're at — type it how you'd say it to a friend.

Optional — these just sharpen the questions. Skip any you're unsure of.

Do you know your last HbA1c? (the diabetes blood number — leave blank if not sure)

Has a doctor ever mentioned any of these?

Is losing weight one of your goals?

Are you worried about hypos (sugar dropping too low)?

Anything that matters to you about treatment? (e.g. fewer tablets, avoiding side effects, trying food/exercise first)

The reframe

Based on the RACGP Management of type 2 diabetes handbook (2024) and the Australian Type 2 Diabetes Glycaemic Management Algorithm (June 2024).

The map — four first-line roads

What each road is, what it actually does, and who the Australian algorithm tends to consider it for. This describes the territory — it is not a recommendation for you.
Road	What it is	What it actually does	Who it's often considered for (AU algorithm)
Lifestyle change	Food pattern, movement, weight, sleep, alcohol, smoking	Can substantially lower blood sugar; meaningful weight loss can put early type 2 diabetes into remission for some. In the Australian DiRECT-Aus primary-care study, 56% of participants reached type 2 diabetes remission at 12 months with a structured weight-management program (mean weight loss 8.1%). Results vary — not a guarantee. Remission is commonly defined as HbA1c <6.5% (48 mmol/mol) for ≥3 months off glucose-lowering medication. DiRECT-Aus, Diabetes Care 2024; Diabetes Australia.	Everyone, at every stage — the foundation under all the others.
Metformin	The long-standing first tablet	Lowers how much sugar the liver makes; weight-neutral; very low hypo risk on its own.	The usual first medicine unless not tolerated or not suitable.
Heart/kidney-protective medicines (SGLT2 inhibitors · GLP-1 receptor agonists)	Newer medicine classes	Lower sugar AND, in the right people, lower the risk of heart failure hospitalisation and slow kidney decline; GLP-1s also drive weight loss.	People with (or at high risk of) heart disease, heart failure, kidney disease, or where weight is a priority.
Combination / step-up	Starting two together, or adding early	Hits sugar from more than one angle; choice shaped by your other conditions.	When one agent won't get you to your target, or your risk profile warrants it upfront.

A common general HbA1c goal is ≤7% (53 mmol/mol), individualised — looser (e.g. <8%) where there's frailty, hypo history, or limited life expectancy. RACGP — Goals for optimum management.

The honest part

The honest part: there is no single 'best' first treatment — the right starting point genuinely depends on you, and only your GP can weigh it with your full picture. Every road has trade-offs. Metformin commonly causes gut upset early (often settles, or a slow-release form helps). SGLT2 medicines raise the risk of genital thrush and, rarely, a serious condition called diabetic ketoacidosis. GLP-1 medicines are usually injections and can cause nausea. And lifestyle change is powerful but hard to sustain alone — needing medication is not a personal failure. This tool can't tell you which road is yours. It hands you the map so the conversation with your GP is a real one.

Three questions that decide which road is yours

Given my heart, kidneys and weight — which first-line road fits me, and why?
What's my HbA1c target, and what's the plan if we don't hit it in 3 months? The Australian algorithm reviews at 3 months — any agent not dropping HbA1c by ≥0.5% should be reviewed. RACGP algorithm.
Could lifestyle change alone get me there first, and is remission realistic for me?
