Understanding Obesity Causes, Risks, and How to Take Control

Have you ever wondered how extra weight affects your body beyond appearance? Obesity isn’t just about size—it’s a serious health condition linked to diabetes, heart disease, joint problems, and mental health concerns. In 2024 alone, 6,687 Queenslanders were hospitalised due to flu, and obesity increases vulnerability to infections due to a weakened immune system.

The good news? Obesity is manageable and even preventable with the right support. This article explores the causes, risks, and solutions for obesity, with a special focus on how physiotherapy plays a vital role in weight management and improving overall health.

What is Obesity?

Obesity is defined as excessive body fat accumulation that poses a health risk. It is commonly measured using the Body Mass Index (BMI), calculated as:

BMI = weight (kg) ÷ height² (m²)

How to Check Your BMI at Home

To calculate your BMI:

• Weigh yourself using a digital scale.
• Measure your height in meters.
• Use the formula BMI = weight (kg) ÷ height² (m²) or use an online BMI calculator.

BMI Categories:

• Underweight: Below 18.5
• Normal weight: 18.5 – 24.9
• Overweight: 25 – 29.9
• Obese: 30 and above

While BMI is a useful tool, it doesn’t account for muscle mass or fat distribution, so it should be used alongside other assessments.

Are You at Risk? Signs to Watch For:

Along with BMI, check for the following signs of health risks:

• Waist Measurement: Risk increases if waist circumference is >94 cm (men) or >80 cm (women).
• Mobility & Pain Issues: Do you experience joint pain, difficulty walking, or breathlessness with minimal activity?
• Energy Levels & Sleep: Do you feel constantly tired, sluggish, or have sleep issues?
• Medical Conditions: Have you been diagnosed with high blood pressure, diabetes, or heart disease? 

If you answered yes to multiple points, seeking professional support can help improve your overall health and mobility.

Health Risks of Obesity

Obesity is a major risk factor for many chronic conditions, such as:

• Cardiovascular Diseases – Excess weight strains the heart, leading to high blood pressure and cholesterol issues (Heart Foundation Australia).
• Type 2 Diabetes – Insulin resistance and increased blood sugar levels.
• Joint and Musculoskeletal Problems – Knee and back pain, osteoarthritis.
• Mental Health Issues – Depression, anxiety, and low self-esteem (Beyond Blue).
• Reduced Mobility and Independence – Difficulty in daily activities and higher risk of falls.

How Physiotherapy Helps in Weight Management

Physiotherapy is often overlooked in obesity management, yet it plays a crucial role in improving movement, reducing pain, and enhancing quality of life. Here’s how physiotherapists can help:

1. Safe and Effective Exercise Programs

Many individuals with obesity struggle with joint pain and mobility issues, making traditional exercise difficult.
Physiotherapists create personalised exercise plans that focus on low-impact movements like hydrotherapy, strength training, and functional exercises to improve mobility and burn calories safely.

2. Pain Management and Joint Protection

Excess weight puts pressure on joints, leading to arthritis, back pain, and knee issues.
Physiotherapists use manual therapy, soft tissue techniques, and exercise modifications to reduce pain and prevent further joint damage.

3. Improving Cardiovascular Fitness

Obesity is linked to poor heart health, and increasing physical activity is key to improving heart and lung function. (Learn more about heart health)
Physiotherapists incorporate gradual, supervised aerobic exercises such as walking, cycling, or swimming to boost stamina and metabolism.

4. Posture and Movement Correction

Extra weight can alter posture and increase the risk of musculoskeletal imbalances.
Physiotherapists help correct posture and movement patterns, preventing injuries and improving functional independence.

5. Education and Lifestyle Guidance

Physiotherapists educate individuals on healthy movement habits, ergonomics, and the importance of an active lifestyle.
They also collaborate with dietitians, exercise physiologists, and psychologists to provide a holistic approach to weight management.

Along with physiotherapy, here are key lifestyle changes to support weight management:

• Balanced Diet – Focus on whole foods, lean proteins, and fibre-rich meals. (Nutritional guidance from our dietitians)
• Regular Physical Activity – Aim for at least 150 minutes of moderate exercise per week.
• Strength Training – Helps build muscle, improve metabolism, and support joint health.
• Quality Sleep & Stress Management – Reduces cravings and supports healthy hormone function. (Sleep Health Foundation Australia) https://www.sleephealthfoundation.org.au/
• Seeking Professional Help – Physiotherapists, dietitians, and psychologists can guide long-term success.
