Newly Diagnosed with Type 2 Diabetes? A Practical Management Guide
By Dr Christopher Irwin · MBChB, FRACGP, MMed (Skin Cancer), FACAM, ASCD · Published 15 July 2026 · Reviewed 15 July 2026
Being diagnosed with type 2 diabetes can feel overwhelming. This is general information to help you understand your diagnosis — bring it along to talk things through with your GP.
The reassuring news is that type 2 diabetes can usually be managed very effectively, particularly when it is identified early.
Type 2 diabetes means that your body is no longer using insulin effectively and may not be producing enough insulin to meet its needs. This causes glucose — often called blood sugar — to build up in your bloodstream. Treatment aims to bring glucose back towards a healthy range and protect your heart, brain, kidneys, eyes, nerves and feet.
At The Local Doctor in Diamond Creek and Ivanhoe, our GPs help patients understand their diagnosis, develop a realistic lifestyle and weight-management plan, select medication when needed, and organise the regular health checks that help prevent diabetes-related complications. We provide ongoing diabetes care for patients throughout Diamond Creek, Ivanhoe, Nillumbik, Banyule and Melbourne’s north-eastern suburbs.
This guide is the overview. Two companion pages go deeper: diet, weight loss and exercise and the medicines used for type 2 diabetes.
What is type 2 diabetes?
When we eat carbohydrate-containing foods, the digestive system breaks some of that carbohydrate down into glucose. Glucose then enters the bloodstream and is used as an important source of energy.
A hormone called insulin, produced by the pancreas, helps move glucose from the bloodstream into the body’s cells.
In type 2 diabetes, two main problems develop:
- Insulin resistance: the muscles, liver and other tissues stop responding to insulin as effectively as they should.
- Reduced insulin production: over time, the pancreas may struggle to produce enough insulin to overcome this resistance.
The result is a persistently elevated blood glucose level. Type 2 diabetes usually develops gradually, and many people have no obvious symptoms when they are first diagnosed.
What is HbA1c?
HbA1c is the blood test most commonly used to diagnose and monitor diabetes. It provides an estimate of your average blood glucose over approximately the previous two to three months.
An HbA1c of 6.5%, or 48 mmol/mol, or higher may indicate diabetes. In someone without clear symptoms, an abnormal result will generally need to be confirmed with another laboratory test.
For many adults with type 2 diabetes, the usual HbA1c treatment target is around:
7%, or 53 mmol/mol, or lower.
This is only a general guide. Your individual target may depend on your age, medications, other health conditions, risk of low blood glucose and personal circumstances.
HbA1c is often checked every three months while treatment is being adjusted. Once diabetes is stable, testing may be spaced to approximately every six months.
Why does controlling diabetes matter?
A high blood glucose level does not always make you feel unwell. However, over many years, excess glucose can gradually damage blood vessels and nerves. This damage is generally divided into microvascular complications, involving the body’s smallest blood vessels, and macrovascular complications, involving the larger arteries.
Diabetic eye disease
Diabetes can damage the small blood vessels at the back of the eye. This is called diabetic retinopathy. Early retinopathy often causes no symptoms — your vision may seem completely normal while changes are already developing.
Everyone diagnosed with type 2 diabetes should have a retinal examination by an optometrist or ophthalmologist at the time of diagnosis. Follow-up is generally required every one to two years, although people at higher risk may need more frequent examinations.
Diabetic kidney disease
The kidneys contain millions of tiny blood vessels that filter the blood. Diabetes can damage these filters, allowing protein to leak into the urine and gradually reducing kidney function. Early kidney disease rarely causes symptoms, so we monitor it using:
- a blood test to measure kidney function
- a urine test for albumin or protein
- regular blood-pressure measurements
A kidney health assessment should generally be completed at least annually.
Nerve damage
Diabetes can damage the nerves, particularly those supplying the feet and lower legs. This is called diabetic peripheral neuropathy. Possible symptoms include numbness or reduced sensation, burning or tingling, shooting pains, increased sensitivity, or a feeling of walking on cotton wool. Some people have significant loss of sensation without noticing any symptoms.
Foot ulcers and infections
Reduced sensation, impaired circulation and slower wound healing can turn a small blister, crack or pressure area into a serious foot ulcer. Your feet should be examined regularly for reduced sensation, circulation problems, skin damage, calluses and pressure areas, changes in foot shape, and poorly healing wounds.
A podiatrist can help with toenail problems, corns, calluses, pressure areas, footwear advice, foot deformities and prevention plans for people with higher-risk feet. Many patients benefit from a baseline podiatry assessment after diagnosis, with the frequency of further appointments depending on your individual level of risk.
Macrovascular complications
Type 2 diabetes also accelerates disease within the larger arteries. This increases the risk of heart attack, stroke, peripheral arterial disease, circulation problems affecting the legs, and cardiovascular death.
For this reason, good diabetes management involves much more than simply lowering your glucose. We also need to manage your blood pressure, cholesterol, weight and waist circumference, smoking status, physical activity, kidney health, sleep and overall cardiovascular risk.
For preventing heart attack and stroke, controlling blood pressure, cholesterol and smoking can be just as important as controlling HbA1c.
Lifestyle is the foundation of treatment
Lifestyle treatment should begin as soon as type 2 diabetes is diagnosed. Medication may also be required, but medicine works best when combined with sustainable changes to eating, movement, weight and other health habits. The aim is not to create a perfect lifestyle overnight — small changes that can be continued for years are more helpful than an extreme plan that lasts only a few weeks.
If you are above your healthiest weight, losing even a relatively modest amount — often an initial target of 5–10% of your starting body weight — can help your body respond to insulin more effectively, and some people who achieve and maintain substantial weight loss reach remission of their diabetes.
Our detailed diet, weight loss and exercise guide covers what to eat, a simple plate method, choosing better carbohydrates, and how much activity to aim for.
Medicines for type 2 diabetes
Lifestyle change is the foundation, but many people also need medication — either from diagnosis or over time as diabetes progresses. Needing medication is not a failure; some medicines are chosen specifically because they protect the heart and kidneys as well as lowering glucose.
Metformin is commonly the first medicine prescribed. Other options include GLP-1 receptor agonists such as Ozempic (semaglutide), SGLT2 inhibitors such as Jardiance and Forxiga, sulfonylureas, DPP-4 inhibitors and insulin. The right choice depends on more than your glucose result — it also considers your weight, kidney function, heart and cardiovascular risk, other conditions and preferences.
Our type 2 diabetes medications guide explains each option, the common side effects, and the Australian brands in more detail.
Will I need to check my glucose every day?
Not necessarily. Regular finger-prick testing is particularly important for people taking insulin or medicines that can cause hypoglycaemia. For someone taking only metformin, Ozempic or certain other medicines with a low risk of hypoglycaemia, daily testing may not provide much benefit. The need for glucose testing should be individualised according to your medications, HbA1c, symptoms, illnesses and treatment plan.
Your diabetes cycle of care
Good diabetes management involves much more than repeating a glucose test.
Usually checked at least every six months:
- weight and waist measurement
- blood pressure
- HbA1c
- medication response and side effects
- foot assessment
Usually checked at least annually:
- cholesterol and triglycerides
- kidney blood tests
- urine albumin or protein
- diet and physical activity
- smoking and alcohol intake
- cardiovascular risk
- vaccinations
- emotional wellbeing and diabetes-related distress
- formal nerve and foot-risk assessment
Eye examinations — arrange an optometry or ophthalmology assessment at the time of diagnosis; every one to two years if no or minimal retinopathy is found; at least annually if you are at higher risk; and more frequently if retinopathy is already present. These intervals may change according to your individual health and results.
Your diabetes healthcare team
Depending on your needs, your care team may include your GP, a practice nurse, a credentialled diabetes educator, an accredited practising dietitian, a podiatrist, an optometrist, an ophthalmologist, an exercise physiologist, an endocrinologist and a pharmacist.
Your GP can also help you register with the National Diabetes Services Scheme (NDSS), which provides access to diabetes information, education, support services and subsidised diabetes products for eligible patients.

Frequently asked questions
- Is type 2 diabetes caused by eating too much sugar?
- Not by itself. Eating a large amount of sugar can contribute to excess energy intake and weight gain, which can increase diabetes risk. However, type 2 diabetes develops through a combination of insulin resistance, genetics, age, body weight, fat distribution, activity levels, medications, health conditions and other factors. A diabetes diagnosis should not be treated as a personal failure.
- Can type 2 diabetes go away?
- Some people can achieve remission, particularly after substantial and sustained weight loss. Remission means glucose levels stay below the diabetes range without glucose-lowering medication for a period of time. However, the underlying tendency towards diabetes remains, and glucose can rise again if weight is regained or pancreatic function declines, so continued monitoring remains necessary even during remission.
- Can I control diabetes without medication?
- Some people with mildly elevated glucose can initially reach their target through eating changes, physical activity and weight loss. Other people need medication from diagnosis because their glucose is significantly elevated, or because a particular medicine offers important heart or kidney protection. Needing medication does not mean that you have failed.
- Will I need to check my glucose every day?
- Not necessarily. Regular finger-prick testing is particularly important for people taking insulin or medicines that can cause hypoglycaemia. For someone taking only metformin, a GLP-1 medicine such as Ozempic, or certain other medicines with a low risk of hypoglycaemia, daily testing may not provide much benefit. The need for testing is individualised according to your medications, HbA1c, symptoms, illnesses and treatment plan.
- Why do I need an eye test when my vision is normal?
- Early diabetic retinopathy usually does not affect your vision. An eye examination can identify changes before you notice symptoms and before permanent vision loss occurs. Everyone diagnosed with type 2 diabetes should have a retinal examination by an optometrist or ophthalmologist at diagnosis, then generally every one to two years, or more often if you are at higher risk.
- Why do I need a foot check when my feet feel normal?
- Loss of sensation can develop gradually and may not be obvious — some people have significant loss of sensation without noticing any symptoms. A foot examination can identify reduced sensation, poor circulation, skin damage or pressure areas before they develop into an ulcer.
