Understanding the weight-arthritis connection: how losing excess weight can alleviate pain

Arthritis is a pervasive challenge that affects millions globally, significantly impacting livelihoods through pain and disability. With over 100 types of this condition, including osteoarthritis, rheumatoid arthritis, and gout, the struggle is both physical and emotional. As millions grapple with the realities of arthritis symptoms, the connection between excess weight and the severity of these symptoms is becoming increasingly clear.

Murray Hewlett, CEO of Affinity Health, sheds light on this connection, stating, “Arthritis already places a tremendous burden on the body, and carrying extra weight adds even more strain to joints. The good news is that even modest weight loss can significantly reduce pain, improve mobility, and enhance quality of life for those living with arthritis.”

Understanding Arthritis

Arthritis encompasses various conditions, primarily characterised by joint inflammation and persistent pain. The most common forms — osteoarthritis, where cartilage wears down over time; rheumatoid arthritis, an autoimmune disorder; and gout, caused by uric acid build-up — all lead to debilitating symptoms such as stiffness, swelling, tenderness, and limited range of motion. This not only hampers daily functions, but also takes a toll on overall well-being.

The weight-arthritis connection

Research consistently demonstrates that carrying excess body weight amplifies arthritis symptoms. Here’s how:

• Increased Joint Pressure: Extra weight places undue pressure on weight-bearing joints such as the knees, hips, and ankles. For instance, every kilogram of body weight adds approximately four kilograms of pressure on the knees during walks.
• Faster Cartilage Breakdown: The additional load can expedite cartilage wear, leading to faster degeneration in osteoarthritis patients.
• Worsened Inflammation: Fat tissue releases inflammatory chemicals that heighten arthritis symptoms, affecting not just weight-bearing joints but also hands, wrists, and other areas.
• Reduced Mobility: Excess weight may lead to inactivity, creating a cycle of declined muscle strength and intensified joint pain.
• Increased Risk of Other Conditions: Obesity is linked to diabetes, heart disease, and metabolic syndrome, complicating both arthritis treatment and general health management.

What you can do

Taking proactive steps towards managing weight can yield significant benefits for arthritis management. Here are some recommendations:

• Focus on Healthy Weight Loss: Even modest weight reductions of 5-10% can lead to noticeable improvements in pain and function. Aim for sustainable, gradual changes over aggressive dieting.
• Adopt a Joint-Friendly Diet: Consuming a diet rich in anti-inflammatory foods can aid in weight management while alleviating arthritis symptoms. Focus on fruits, vegetables, whole grains, lean proteins, and healthy fats, while minimising processed foods and sugars.
• Stay Active: Physical activity, particularly low-impact exercises like swimming, walking, and yoga, can alleviate pain and enhance flexibility. Always consult a healthcare professional before starting any new exercise programme.
• Strengthen Supporting Muscles: Building muscle around affected joints helps reduce stress and bolster stability. Consider physical therapy or guided strength training.
• Manage Pain and Inflammation: Use over-the-counter pain relief or prescribed medications and explore complementary therapies, such as massages or acupuncture, for flare-up relief.
• Seek Professional Support: Working with healthcare providers, such as doctors, dietitians, and physiotherapists, can yield tailored management plans.

Emotional Health

The physical struggle of living with arthritis can take an emotional toll. Anxiety, frustration, and even depression are all too common. Engaging with friends and loved ones, joining support groups, or consulting a professional can help maintain a positive outlook during challenging times.

While managing arthritis alongside excess weight may seem daunting, embracing small, consistent lifestyle changes can lead to significant improvements, says Hewlett. A balanced diet, regular low-impact exercise, and professional support not only ease symptoms but also enhance mobility, ultimately promoting a healthier, more confident life.
