What Is Rheumatology?

Overview and definition

Rheumatology is a branch of internal medicine focused on diagnosing and treating rheumatic diseases. These illnesses often cause inflammation, swelling, and pain in the joints or muscles. Today, rheumatology covers much more than just common aches. It mainly addresses autoimmune diseases, where the immune system attacks healthy tissues. This can affect not only bones, joints, and muscles, but also organs like the kidneys, lungs, heart, and skin. There are over 200 different diseases in this field, such as Rheumatoid Arthritis, Systemic Lupus Erythematosus (SLE), Ankylosing Spondylitis, Gout, and Sjogren’s Syndrome. Since these conditions are usually long-term and affect the whole body, rheumatologists use advanced treatments to slow disease progress and help prevent lasting damage.

What Are Rheumatic Diseases?

Rheumatology

Rheumatic diseases are autoimmune and inflammatory conditions where the immune system attacks the lining of joints and other tissues. They usually cause pain, swelling, and stiffness. Without treatment, these diseases can lead to serious joint damage and loss of movement.

Medical Center and Expertise

307 LIV Hospital

Our specialized Early Arthritis Clinic is set up to diagnose patients as soon as symptoms begin, which is a crucial time for treatment. We also have an infusion center where patients receive advanced biologic therapies in a comfortable environment. Musculoskeletal Ultrasound (MSUS) is used to see joint inflammation in real time and to guide injections accurately.

The Morning Signal

An interesting piece of information: Share an interesting fact: A hallmark sign of inflammatory arthritis is “morning stiffness” that lasts longer than 30 minutes. Unlike mechanical back pain, which worsens with activity, inflammatory pain often improves with movement, suggesting a systemic rather than structural issue.

Understanding Rheumatic Conditions and Body Impact

Chronic inflammation from these diseases does more than harm cartilage and bone. It releases chemicals into the blood that can cause deep tiredness, mild fevers, and trouble thinking clearly. It also speeds up hardening of the arteries, raising the risk of heart disease. In illnesses like Lupus or Scleroderma, inflammation can scar the lungs or hurt the kidneys, so regular checks of these organs are very important.

How Conditions Are Diagnosed at Liv Hospital

Diagnosing these conditions often feels like detective work. Doctors use blood tests to look for autoantibodies (ANA, Rheumatoid Factor, Anti-CCP) and signs of inflammation (CRP, ESR). They also use advanced imaging, such as MRI, to spot inflammation in the bone before any damage shows up on an X-ray.

The Role of Your Rheumatologist

Your rheumatologist is your long-term partner in care. Their main goal is to help you reach remission, meaning no symptoms. They keep track of your immune system and adjust your medications to control inflammation, while also watching for side effects. They can tell the difference between active inflammation and lasting damage.

Personalized Treatment Plans

Treating rheumatic diseases has moved beyond just using painkillers. Now, the standard approach is called “Treat to Target,” which uses DMARDs (Disease-Modifying Antirheumatic Drugs) and Biologics. These medicines are designed to block specific parts of the immune system and stop the disease at its source.

Your Treatment Journey

Outline the patient’s path. It usually starts with a “bridge therapy” (like steroids) to quickly stop pain, followed by the introduction of long-term maintenance medication. The journey involves regular blood monitoring (every 1-3 months) to ensure the liver and kidneys are handling the medication well.

Multidisciplinary Rheumatology Board

Rheumatologists work closely with other specialists to give patients the best care. They team up with orthopedic surgeons for joint replacements if needed, physical therapists to help keep patients moving, and nephrologists for kidney problems in conditions like Lupus. Ophthalmologists also play an important role in checking for eye inflammation, which is common in these diseases.

What Patients Should Know Before Treatment

Advise patients on preparation. Because treatments suppress the immune system, patients must screen for latent infections (such as tuberculosis) and update vaccinations before starting treatment. They should know that biologic drugs are powerful and require vigilance—any fever or infection must be reported to the doctor immediately.

FREQUENTLY ASKED QUESTIONS

What is the difference between a Rheumatologist and an Orthopedist?

While both treat joint and muscle problems, their focus differs.

  • Rheumatologists are internal medicine specialists who focus on the medical management (using medication and lifestyle changes) of autoimmune and inflammatory conditions like Rheumatoid Arthritis and Lupus.
  • Orthopedists are surgeons who focus on mechanical injuries and structural corrections, and who perform surgeries such as joint replacements.

The key difference often lies in morning stiffness and activity:

  • Inflammatory Pain (e.g., RA, Ankylosing Spondylitis): Stiffness lasts for more than 30 minutes (often hours) after waking up. Surprisingly, the pain improves as you move around and gets worse if you sit still for too long.
  • Mechanical Pain (e.g., Osteoarthritis): Stiffness is brief (less than 30 minutes). The pain gets worse with activity and feels better when you rest.

This refers to the critical early months of the disease. Identifying and treating Rheumatoid Arthritis (RA) aggressively during this early phase can prevent permanent joint damage and deformity. Delaying treatment often results in irreversible destruction of the cartilage and bone.

ANA (Antinuclear Antibody) is a screening test. A positive result indicates that your immune system is producing antibodies that target your own cells. While it is the hallmark screening test for Systemic Lupus Erythematosus (SLE), a positive ANA does not automatically mean you have Lupus; further specific testing is required to confirm a diagnosis.

Raynaud’s is a condition where the blood vessels in the fingers or toes overreact to cold or stress. The digits typically turn white (due to lack of blood flow), then blue (due to lack of oxygen), and finally red (as blood rushes back). It is a common early sign of connective tissue diseases like Scleroderma and Lupus.
