Osteoarthritis

Overview

Osteoarthritis is a chronic degenerative joint disease characterized by cartilage breakdown, joint inflammation, and reduced mobility. Obesity is one of the strongest risk factors because excess weight increases mechanical stress on weight‑bearing joints and promotes systemic inflammation. Osteoarthritis commonly affects the knees, hips, spine, and hands, leading to pain, stiffness, and decreased quality of life.

Causes

Causes include aging, obesity, joint overuse, prior injuries, genetics, metabolic inflammation, and biomechanical stress. Obesity accelerates cartilage wear and increases inflammatory mediators.

Risk Factors

Risk factors include obesity, age, female sex, prior joint injuries, repetitive stress, genetics, and metabolic syndrome.

How Osteoarthritis Affects the Body

Cartilage wears down, joint space narrows, and bone spurs form. Inflammation increases pain, stiffness, and reduced mobility. Obesity worsens symptoms by increasing joint load and systemic inflammation.

Complications

Complications include chronic pain, reduced mobility, disability, joint deformity, and increased risk of falls. Severe cases may require joint replacement surgery.

Symptoms & Signs

Symptoms include joint pain, stiffness (especially in the morning), swelling, reduced range of motion, grinding sensations, and difficulty with walking or climbing stairs.

Diagnosis

Diagnosis includes physical exam, X‑rays, MRI (when needed), and evaluation of joint function. Lab tests may be used to rule out inflammatory arthritis.

Differential Diagnosis

Includes rheumatoid arthritis, gout, psoriatic arthritis, bursitis, tendonitis, and fibromyalgia.

Lifestyle Modifications

Lifestyle strategies include weight loss, low‑impact exercise, physical therapy, strengthening programs, joint protection techniques, and anti‑inflammatory nutrition.

Treatment Options

Treatment includes NSAIDs, joint injections, physical therapy, weight‑loss medications, bariatric surgery, bracing, and orthopedic referral for advanced cases. Weight loss significantly reduces joint pain and improves mobility.

When to See a Doctor

Seek evaluation if joint pain persists, mobility decreases, or daily activities become difficult.

When to Seek Treatment

Treatment is recommended when pain affects function, when conservative measures fail, or when obesity contributes to worsening symptoms.

Long-Term Outlook

Long‑term management focuses on weight control, joint protection, physical activity, and monitoring for progression. Bariatric surgery can dramatically improve symptoms in patients with obesity.

‍

Prognosis

Osteoarthritis is progressive but manageable. Weight loss and early treatment significantly improve long‑term outcomes.
