Understanding Rheumatoid Arthritis: A Guide to Early Detection and Treatment

Rheumatoid arthritis (RA) is a chronic autoimmune disease that affects millions of people globally, including in India. In a country where joint pain is frequently dismissed as a part of ageing or overlooked due to limited access to rheumatological care, the importance of recognizing the early signs of RA cannot be overstated. If left untreated, this progressive condition can cause joint deformities, bone erosion, and severe disability. To help, this guide aims to shed some light on the symptoms, risk factors, early diagnosis, and treatment options for rheumatoid arthritis. 

What is Rheumatoid Arthritis? 

Rheumatoid arthritis (RA) is a chronic autoimmune disease in which the body’s immune system mistakenly attacks its own tissues, particularly the synovium—the lining of the joints. It causes inflammation, pain, swelling, and stiffness in the joints, typically affecting both sides of the body symmetrically, such as both wrists, knees, or hands. 

What are the Stages of Rheumatoid Arthritis? 

Rheumatoid arthritis (RA) progresses through different stages, each characterised by specific symptoms and levels of joint damage. Below are four main stages of rheumatoid arthritis:

What are the Early Signs and Symptoms of Rheumatoid Arthritis? 

Recognizing the early signs of rheumatoid arthritis is crucial for timely diagnosis and treatment, as this can prevent irreversible joint damage. Below are the key signs and symptoms of rheumatoid arthritis to watch out for:

• Joint Pain and Tenderness – Persistent joint pain and tenderness in the joints, particularly in smaller joints like the fingers, wrists, and toes, are often among the first symptoms of rheumatoid arthritis.
• Morning Stiffness – Joint stiffness lasting more than 30 minutes after waking is a hallmark of rheumatoid arthritis, even in the early stages.
• Swelling in Joints – Swelling in the hands and feet, often with warmth and redness, is an early indicator of inflammation linked to rheumatoid arthritis.
• Fatigue and Weakness – Fatigue, weakness, and low energy levels frequently occur in rheumatoid arthritis, often preceding severe joint problems.
• Symmetrical Joint Pain – Early signs and symptoms of rheumatoid arthritis often include pain that affects both sides of the body, such as both wrists or knees, distinguishing it from other forms of arthritis.
• Minor Joint Deformities – Although more common in advanced stages, early deformities like slight misalignment of fingers or toes may occur in people dealing with RA.
• Low-Grade Fever – Mild fever or a sense of malaise may signal early rheumatoid arthritis, particularly during flares.
• Reduced Range of Motion – Stiffness and swelling can limit joint mobility, even in the early stages of the disease, making everyday tasks increasingly difficult.
• Rheumatoid Nodules (Rare in Early Stages) – Small, firm lumps, known as rheumatoid nodules, may form under the skin in some cases, though they are more commonly seen in advanced stages of rheumatoid arthritis.

Recognizing these early signs of rheumatoid arthritis can lead to a prompt diagnosis, which is essential to starting treatment and preventing joint damage.

What Causes Rheumatoid Arthritis? 

The exact cause of rheumatoid arthritis (RA) is unknown but likely involves a combination of genetic, environmental, and hormonal factors. RA is an autoimmune condition, meaning the immune system mistakenly attacks the body’s own tissues, particularly the joints. Key factors contributing to the development of rheumatoid arthritis include:

• Immune System Dysfunction
• Genetics
• Environmental Triggers such as infections, air pollution, and occupational hazards
• Smoking
• Hormonal Changes, especially in women
• Obesity
• Infections
• Imbalanced Gut Microbiome

While no single cause of RA has been identified, understanding potential rheumatoid arthritis causes helps in early recognition and effective management. 

What are the Complications of RA? 

If left untreated or poorly managed, rheumatoid arthritis (RA) can lead to various complications, affecting not only the joints but also other systems in the body. Here are the primary complications associated with rheumatoid arthritis disease:

How is Rheumatoid Arthritis Diagnosed?

Diagnosing rheumatoid arthritis (RA) involves a combination of medical history evaluation, physical examinations, imaging tests, and laboratory analyses. Early diagnosis is vital for initiating treatment and averting long-term joint damage. Here’s how diagnosing rheumatoid arthritis typically proceeds:

1. Medical History: The doctor assesses symptoms like joint pain, stiffness, and swelling, particularly symmetrical occurrences. Additionally, the doctor may review the patient’s family history for autoimmune diseases, including rheumatoid arthritis, to assess potential risk factors.
2. Physical Examination: During a physical examination, the doctor evaluates the joints for swelling, warmth, tenderness, and range of motion. Specific signs like joint deformities, redness, or nodules under the skin are examined.
3. Blood Tests: Several blood tests are conducted to confirm rheumatoid arthritis symptoms and differentiate it from other conditions:

• Rheumatoid Factor (RF): Detects an antibody commonly found in RA patients, though not exclusively.
• Anti-Cyclic Citrullinated Peptide (Anti-CCP): A more specific marker for RA, often confirming the diagnosis.
• Erythrocyte Sedimentation Rate (ESR) and C-Reactive Protein (CRP): Measure inflammation levels in the body.
• Complete Blood Count (CBC): Identifies anaemia, which is common in RA patients.

4. Imaging Tests

• X-rays: Used to detect joint damage, though early-stage changes might not be visible..
• Ultrasound or MRI: Provide more detailed images to assess inflammation and joint damage in early RA.

5. Joint Fluid Analysis: A small sample of fluid from the affected joint is extracted and analysed to rule out other conditions like gout or infection.

How is Rheumatoid Arthritis Treated? 

Rheumatoid arthritis (RA) is treated to reduce pain, control inflammation, and prevent joint damage. Although rheumatoid arthritis has no permanent cure, effective management enhances quality of life. The RA treatment entails:

Medications:

• DMARDs and Biologics: Decelerate disease progression and safeguard joints.
• Pain Relievers (NSAIDs): Reduce pain and swelling.
• Steroids: Quickly ease severe symptoms during flares.

Physical Therapy: Exercises to improve joint movement and strength.

Lifestyle Changes: Regular exercise, a healthy diet, stress management, and maintaining a healthy weight help control symptoms.

Surgery for Rheumatoid Arthritis

Surgery may become necessary for individuals with severe rheumatoid arthritis (RA) when medications and other treatments fail to manage symptoms or prevent joint damage. The goal of surgery is to reduce pain, improve joint function, and enhance overall quality of life. Common surgical options for RA include:

• Joint Replacement (Arthroplasty): Severely damaged joints, such as hips or knees, are replaced with prosthetic implants to restore mobility and reduce pain.
• Synovectomy: Removal of the inflamed synovium (joint lining) to reduce swelling and alleviate discomfort in affected joints.
• Tendon Repair: Tendons around inflamed joints may become damaged or rupture over time. Tendon repair surgery restores functionality and stability to the affected area.
• Joint Fusion (Arthrodesis): Fusing bones within a joint to stabilise it and reduce pain, often used when joint replacement is not viable.

Surgical intervention is typically considered as a last resort for managing rheumatoid arthritis after all other rheumatoid arthritis therapies have been exhausted.

Diet and Nutrition Tips for Managing Rheumatoid Arthritis

While there’s no specific diet to cure rheumatoid arthritis (RA), certain foods can help reduce inflammation, strengthen the immune system, and support joint health. Making informed dietary choices can complement medical treatments and improve quality of life. Here are some key tips:

Include Anti-Inflammatory Foods

Anti-inflammatory foods that can help alleviate rheumatoid arthritis symptoms include:

• Fatty Fish: Salmon, mackerel, and tuna are high in omega-3 fatty acids, which can help reduce joint inflammation.
• Fruits and Vegetables: Rich in antioxidants, colourful produce like berries, spinach, and broccoli combat oxidative stress.
• Olive Oil: A healthy fat that contains compounds with anti-inflammatory effects.

Avoid Inflammatory Triggers

Certain foods can worsen inflammation and should be limited:

• Processed Foods: Contain trans fats and added sugars, exacerbating inflammation.
• Refined Carbs: White bread, pastries, and sugary snacks can increase inflammation.
• Red Meat: May trigger inflammation in some individuals.

Opt for Whole Grains

Opt for whole grains such as quinoa, oats, and brown rice, as they are rich in fibre, which helps lower inflammation markers in the body.

Stay Hydrated

Drink plenty of water to stay hydrated and help flush toxins from the body. Avoid sugary drinks that may promote inflammation.

Add Vitamin D and Calcium

RA increases the risk of osteoporosis, so include calcium-rich foods (e.g., dairy, fortified plant milk) and vitamin D sources (e.g., sunlight, fatty fish).

Limit Salt and Sugar

Excessive salt and sugar can exacerbate inflammation and can contribute to other health problems such as hypertension.

Try Supplements (with Medical Advice)

Supplements like omega-3s, turmeric (curcumin), and vitamin D may provide additional anti-inflammatory benefits. Always consult a doctor before starting supplements.

Sample RA-Friendly Diet

• Breakfast: Oatmeal topped with berries and chia seeds.
• Lunch: Grilled salmon with quinoa and steamed spinach.
• Snacks: A handful of walnuts or an apple with almond butter.
• Dinner: Stir-fried vegetables with tofu and brown rice.
