Common Types of Chronic Diseases and How to Manage Them
Hearing that you have a chronic disease can bring up a lot of questions. What does this mean? Will it get worse? Can I still live a normal life? These are concerns we hear from patients every week at Main Street Medical Centre.
The good news is that many chronic conditions can be managed well with the right support. While they often require ongoing care rather than a cure, early diagnosis, regular check-ups, and healthy lifestyle changes can make a real difference. In fact, many people continue working, staying active, and enjoying life by following a personalised management plan.
In this guide, we’ll explain some of Australia’s most common chronic diseases, what causes them, and how they can be managed with practical, evidence-based advice.
10 Common Types of Chronic Diseases in Australia
Chronic diseases are Australia’s biggest health challenge. Around 6 in 10 Australians live with at least one long-term health condition, and many manage more than one at the same time. Together, these conditions contribute to 66% of Australia’s disease burden and almost 9 in 10 deaths.
The good news? Many complications can be delayed, or even prevented, through early intervention, regular GP care, and healthy lifestyle choices.
| Chronic Disease | Australians Affected | Common Causes | Medicare & GP Support | Recommended Management |
| Mental & Behavioural Conditions | 26.1% | Genetics, trauma, chronic stress, and social factors | Mental Health Treatment Plan, psychology referrals | Therapy, medication, and ongoing GP reviews |
| Back Problems | 15.7% | Poor posture, ageing, injuries, repetitive strain | GP care and allied health referrals | Physiotherapy, staying active, and pain management |
| Arthritis | 14.5% | Ageing, obesity, family history, and autoimmune disease | GP care and allied health support | Exercise, medication, weight management |
| Asthma | 10.8% | Allergies, pollution, genetics | Spirometry, Asthma Action Plan | Inhalers, trigger management, and regular reviews |
| Diabetes | 5.3% | Obesity, inactivity, and poor diet | Diabetes educators, dietitians, PBS medicines | Lifestyle changes and blood sugar monitoring |
| Cardiovascular Disease | 5.2% | Smoking, high blood pressure, and cholesterol | Heart Health Checks and specialist referrals | Risk assessment and medication |
| Osteoporosis | 3.4% | Ageing, menopause, low calcium | Bone density scans and GP care | Exercise, calcium, Vitamin D |
| COPD | 2.5% | Smoking, pollution, and workplace exposure | Respiratory specialists and rehabilitation | Smoking cessation and inhaler therapy |
| Cancer | 1.8% | Smoking, UV exposure, alcohol, and obesity | National screening programs | Early detection and specialist treatment |
| Chronic Kidney Disease | Around 1 in 10 show signs | Diabetes, high blood pressure | Kidney Health Checks | Regular monitoring and blood pressure control |
The table above provides a quick snapshot. Now, let’s take a closer look at each chronic disease and how it can be managed.
1. Mental and Behavioural Conditions
Mental health matters just as much as physical health, but it’s still the topic people are most hesitant to bring up. Anxiety and depression are among the most common mental health conditions in Australia, but they are not the only ones. Financial stress, trauma, ongoing illness, big life changes, and genetics can all play a role.
At Main Street Medical Centre, we’ve seen firsthand how much earlier support can change someone’s path. Plenty of patients tell us they wish they’d come in sooner instead of trying to push through alone. The sooner we pick up a condition, the sooner we can build a plan around both your mental and physical well-being.
How to manage it:
- A thorough first conversation about your symptoms, daily life, and overall health
- A Mental Health Treatment Plan, if appropriate, with Medicare-subsidised referrals to a psychologist
- Support through cognitive behavioural therapy (CBT), lifestyle changes, or medication where needed
- Regular follow-ups to check how things are progressing
You don’t have to manage it alone, and the right support can make a real difference.
2. Back Problems
Almost everyone deals with back pain at some point. The trouble starts when it lingers for months or keeps coming back. That’s when it stops being a minor inconvenience and starts affecting sleep, mobility, and everyday tasks.
Here’s something worth knowing: most chronic back pain isn’t caused by a serious spinal condition. It’s far more often linked to muscle strain, poor posture, repetitive movement, ageing, or too many hours sitting down. Stress and anxiety can also amplify pain, creating a loop that’s hard to break without proper guidance.
How to manage it:
- Staying gently active. Complete rest is one of the biggest myths in back pain treatment
- A proper assessment to pinpoint the actual cause before any plan is made
- Physiotherapy, strengthening exercises, and posture correction
- Pain management strategies or further investigation if things aren’t improving
- On-site physiotherapy for coordinated care without long delays
3. Arthritis
Arthritis gets lumped in with “getting older”, but that’s only half the picture. It’s actually a group of more than 100 conditions affecting the joints, and it can show up at almost any age. Osteoarthritis, rheumatoid arthritis, and gout are the types we see most often.
We’ve had patients put off treatment for years, assuming stiff or sore joints were just part of ageing. Unfortunately, waiting usually gives the condition more time to progress. Getting assessed early gives you a better chance of managing pain and staying active.
How to manage it:
- Regular low-impact exercise
- Maintaining a healthy weight to ease pressure on joints
- Medication where appropriate
- Physiotherapy or allied health support
- A Chronic Disease Management Care Plan to coordinate ongoing care
Arthritis can’t always be cured, but it can almost always be managed well.
4. Asthma
Some Australians grow up with asthma; others develop it as adults. Either way, it’s not something to brush off just because symptoms come and go.
Asthma inflames and narrows the airways, making breathing harder. You might notice wheezing, chest tightness, coughing, or shortness of breath, triggered by exercise, cold weather, or allergy season. Common triggers include pollen, dust mites, smoke, pet dander, viral infections, and air pollution.
A question we hear a lot is, “My asthma only bothers me occasionally; do I really need treatment?” The honest answer depends on how well-controlled it is. Even mild, occasional symptoms can escalate if they’re not monitored properly.
How to manage it:
- Reviewing your symptoms and inhaler technique
- Building or updating a personalised Asthma Action Plan
- Lung function testing (spirometry), where needed
- Regular follow-ups to confirm treatment is still working
- Avoiding known triggers, staying active, and keeping vaccinations current
Good asthma management is about preventing flare-ups, not just reacting to them.
5. Diabetes
Diabetes is one of the fastest-growing chronic diseases in Australia, and most cases are Type 2. It develops when the body becomes resistant to insulin or doesn’t produce enough of it, leaving blood sugar levels higher than they should be.
The tricky part is that diabetes often develops quietly, with symptoms going unnoticed until the condition has already started causing damage. Left unmanaged, it raises the risk of heart disease, kidney disease, vision loss, and nerve damage.
Many patients feel overwhelmed at diagnosis, understandably so. But management doesn’t happen overnight. Small, consistent changes can lead to the biggest improvements.
How to manage it:
- Monitoring blood glucose levels and reviewing HbA1c results
- The SNAP approach: quitting Smoking, improving Nutrition, reducing harmful Alcohol intake, and increasing Physical activity
- Coordinated care with diabetes educators, dietitians, or other allied health professionals
- A Chronic Disease Management Care Plan and regular reviews to adjust treatment over time
6. Cardiovascular Disease (Heart Disease, Stroke & Vascular Disease)
Heart disease tends to build quietly over years; it’s one of the reasons it remains one of Australia’s leading causes of death. Most people don’t wake up with heart disease one day; it’s usually the result of risk factors accumulating over time.
High blood pressure, high cholesterol, smoking, diabetes, carrying extra weight, poor nutrition, and inactivity all put extra strain on the heart and blood vessels. Family history can raise your risk, too, even if you feel completely well.
Rather than waiting for symptoms, we encourage patients to think prevention first. A simple check today can catch risks before they turn into an emergency tomorrow.
How to manage it:
- Assessing risk using the Australian CVD Risk Calculator and Medicare Heart Health Checks
- A personalised plan covering diet, activity, blood pressure, and cholesterol
- Support to quit smoking, plus medication where appropriate
- ECGs and ongoing monitoring to track cardiovascular health over time
7. Osteoporosis (or Osteopenia)
Unlike most chronic conditions, osteoporosis usually doesn’t hurt in its early stages. Many people only find out they have it after breaking a bone in what seemed like a minor fall.
Osteoporosis gradually weakens bones, making fractures, especially in the hips, spine, and wrists, more likely. Women are at higher risk after menopause, but men can be affected too, particularly with age. Low calcium intake, vitamin D deficiency, smoking, long-term steroid use, and family history all play a part.
Because bone loss happens gradually and silently, regular screening becomes more important as you get older.
How to manage it:
- A bone density (DXA) scan if you’re at higher risk
- Weight-bearing exercise and strength training
- Adequate calcium and vitamin D intake
- Falls prevention at home
- Prescription medication, where appropriate, to strengthen bone and reduce fracture risk
Early action here can make a real difference to your independence later in life.
8. Chronic Obstructive Pulmonary Disease (COPD)
COPD is a long-term lung disease that makes breathing progressively harder. It covers conditions like chronic bronchitis and emphysema, both of which restrict airflow and make everyday activities more tiring than they should be.
Smoking is the biggest risk factor, but it’s not the only one; years of exposure to workplace dust, chemical fumes, air pollution, or second-hand smoke can also damage the lungs. Many people dismiss breathlessness as “just getting older” or “a bit unfit.” Persistent coughing, excess mucus, wheezing, or shortness of breath deserve a proper check.
How to manage it:
- Quitting smoking or vaping. It’s never too late to slow further lung damage
- Medications, inhalers, and vaccinations to reduce flare-ups
- Pulmonary rehabilitation, where appropriate
- Ongoing monitoring of lung health, with referral to a respiratory specialist if needed
Managing COPD is about protecting the lung function you still have.
9. Cancer
Hearing the word “cancer” is frightening, but outcomes have improved significantly over the past few decades thanks to earlier diagnosis, better treatment, and national screening programmes.
Cancer develops when abnormal cells grow uncontrollably and potentially spread elsewhere in the body. Not every cancer can be prevented, but a large share of cases in Australia are linked to controllable factors, such as smoking, excessive alcohol, obesity, poor diet, and UV exposure.
Screening isn’t about expecting bad news. It’s about giving yourself the best possible chance if something is found.
How to manage it:
- Participating in BreastScreen, the National Bowel Cancer Screening Program, and the Cervical Screening Program
- Prompt referrals for imaging, pathology, or specialist oncology care if something needs a closer look
- Ongoing GP support through and after treatment, managing side effects, monitoring recovery, and looking after your overall wellbeing
10. Chronic Kidney Disease
Your kidneys work around the clock, filtering waste and balancing fluids throughout the body. The catch is that chronic kidney disease (CKD) often develops silently; people can lose a significant amount of kidney function before noticing anything’s wrong.
Diabetes and high blood pressure are the two leading causes of CKD in Australia, which is why regular checks matter if you have either condition. Fatigue, swelling, changes in urination, or nausea tend to show up later, meaning symptoms alone aren’t a reliable early warning sign.
How to manage it:
- Kidney Health Checks: blood pressure measurement, eGFR blood tests, and uACR urine tests
- Managing blood pressure and diabetes
- Reviewing medications that may affect kidney function
- Support for healthier lifestyle habits
- Referral to renal specialists for more advanced cases, keeping care proactive rather than reactive
