Type 2 Diabetes

Type 2 diabetes is a long-term condition where the body does not use insulin effectively, leading to high blood sugar levels.

When to consult a doctor for type 2 diabetes

If you experience ongoing symptoms of high blood sugar

See a GP if you notice frequent urination, excessive thirst, persistent dry mouth, unexplained weight changes, constant fatigue, or blurred vision. These symptoms may indicate poor blood sugar control and require medical assessment.

If wounds heal slowly or you notice nerve-related symptoms

Consult a doctor if cuts, sores, or infections take longer than usual to heal, or if you experience numbness, tingling, or burning sensations in your hands or feet, as these can be early signs of diabetes-related complications.

If you have risk factors or a family history of diabetes

Speak to a GP if type 2 diabetes runs in your family or if you have risk factors such as obesity, high blood pressure, high cholesterol, or a sedentary lifestyle. Early screening and treatment can help prevent long-term complications.

Symptoms

Some of the symptoms of type 2 diabetes include:

Increased thirst & frequent urination: High blood sugar levels cause excessive thirst and frequent urination.
Unexplained weight loss: Despite normal or increased appetite, the body may break down muscle and fat for energy.
Fatigue & low energy: High blood sugar levels can lead to persistent tiredness and sluggishness.
Blurred vision: Excess glucose can affect the eyes, causing temporary or long-term vision problems.
Slow-healing wounds & infections: Cuts, sores, or infections may take longer to heal.
Tingling or numbness: Nerve damage can cause tingling, pain, or numbness in the hands and feet.
Frequent infections: High sugar levels can weaken the immune system, increasing the risk of skin, gum, and urinary tract infections.
Darkened skin patches: Areas of dark, velvety skin, often around the neck or armpits, can be an early warning sign of insulin resistance.

Causes

Type 2 diabetes develops when the body becomes resistant to insulin or doesn’t produce enough insulin to maintain normal blood sugar levels. Several factors contribute to this condition, including:

Insulin resistance: The body’s cells don’t respond properly to insulin, leading to high blood sugar levels.
Genetics & family history: Having a close family member with type 2 diabetes increases the risk.
Being overweight or obese: Excess fat, particularly around the abdomen, is linked to insulin resistance.
Sedentary lifestyle: Lack of physical activity reduces insulin sensitivity, making it harder to regulate blood sugar.
Unhealthy diet: High consumption of processed foods, sugary drinks, and refined carbohydrates contributes to weight gain and insulin resistance.
High blood pressure & cholesterol: These conditions are often associated with insulin resistance and metabolic syndrome.
Gestational diabetes history: Women who had diabetes during pregnancy are at higher risk of developing type 2 diabetes later in life.

Telehealth for Type 2 Diabetes

Speak to a GP first to get medical advice and check your symptoms

Hola Health provides a convenient way for you to consult a doctor online, 24/7 across Australia. Our AHPRA-registered Australian online GP will conduct a comprehensive assessment to provide the best possible care.

Clinical note: An online GP assessment helps provide medical advice for your diabetes symptoms and evaluate if a face-to-face consultation or physical examination is needed. Online GPs can provide prescriptions, referrals or online medical certificate if clinically indicated. Telehealth is a complementary service; it is not suitable for the initial diagnosis of diabetes or the management of acute complications. Regular physical examinations (including foot checks, eye exams, and blood pressure monitoring) and in-person pathology tests (such as HbA1c and kidney function tests) are mandatory for safe long-term management. After-hours bulk billing is available for eligible patients during Medicare-defined periods; otherwise, private fees apply. Consultations are secure, encrypted, and Australian-stored (in compliance with the Australian Privacy Principles). In case of confusion, persistent vomiting, fruity-smelling breath, or rapid breathing, call 000 immediately. We recommend sharing your consult summaries with your regular GP and Endocrinologist to ensure continuity of care.
