Reiter's Disease Is a Type of Reactive Arthritis That Follows a Bacterial Infection

Reiter's disease is an inflammatory condition that develops after a bacterial infection elsewhere in your body — usually in your digestive tract or urinary system. The infection itself may clear up, but weeks later your joints, eyes, and urinary tract become inflamed. It is one form of reactive arthritis, a broader category of joint inflammation triggered by infection.

The condition was named after Hans Reiter, a German physician who described it in 1916. Modern medical practice increasingly uses the term "reactive arthritis" instead, because the older name carried associations with Reiter's involvement in Nazi medicine. The underlying condition remains the same regardless of terminology.

Reiter's disease typically affects people in their 20s and 40s, though it can occur at any age. It is more common in men than women. The condition is not contagious — you cannot catch it from someone who has it — but the bacterial infection that triggers it may be.

Key Takeaways

  • Reiter's disease develops weeks after a bacterial infection in the gut or urinary tract, not during the infection itself.
  • The classic triad of symptoms includes joint inflammation, eye inflammation, and urinary tract symptoms, though not everyone experiences all three.
  • Certain bacteria — including those that cause food poisoning and sexually transmitted infections — are known triggers.
  • The condition usually resolves within months, but some people develop chronic symptoms that persist for years.
  • Blood tests and imaging can support a diagnosis, but there is no single test that confirms Reiter's disease on its own.

The Three Main Symptom Areas: Joints, Eyes, and Urinary Tract

Reiter's disease typically causes inflammation in three areas of the body, though not everyone develops symptoms in all three. The pattern is sometimes called the "classic triad," but many people experience only one or two of these areas.

Joint inflammation is the most common symptom. It usually starts in the knees, ankles, or feet and can spread to other joints. The affected joints become swollen, warm, and painful, especially in the morning or after rest. Some people develop inflammation where tendons attach to bone, causing heel pain or pain along the sole of the foot.

Eye inflammation occurs in roughly half of people with Reiter's disease. The most common form is conjunctivitis — redness and irritation of the membrane covering the white of the eye. Some people develop inflammation inside the eye (uveitis), which causes pain, blurred vision, and sensitivity to light. Eye symptoms may come and go.

Urinary tract symptoms include painful urination, frequent urination, or discharge from the urethra. These symptoms can resemble a urinary tract infection or sexually transmitted infection, but they persist even after antibiotic treatment for those conditions. Some people also develop inflammation of the prostate (in men) or cervix (in women).

Other symptoms may include mouth ulcers, skin rashes (especially on the palms and soles), and general fatigue. Fever is uncommon unless the triggering infection is still active.

Which Infections Trigger Reiter's Disease

Reiter's disease develops after specific bacterial infections. The bacteria themselves do not directly cause the joint and eye inflammation — instead, the immune system's response to the infection triggers the symptoms weeks later. This is why the condition is called "reactive" arthritis.

Gastrointestinal infections are a common trigger. Bacteria including Shigella, Salmonella, Yersinia, and Campylobacter — organisms that cause food poisoning — can precede Reiter's disease. The original infection may have caused diarrhea or abdominal pain that resolved, but the reactive arthritis develops afterward.

Sexually transmitted infections are another major trigger. Chlamydia trachomatis is the most frequently identified culprit. Gonorrhea and other urogenital bacteria can also trigger the condition. A person may not have noticed symptoms of the initial infection, or symptoms may have been mild.

Other bacteria linked to Reiter's disease include Ureaplasma and Mycoplasma species. In rare cases, respiratory infections have preceded the condition, though this is less common than gastrointestinal or urogenital triggers.

Not everyone exposed to these bacteria develops Reiter's disease. Genetic factors play a role — people who carry a specific genetic marker called HLA-B27 are at higher risk. However, many people with HLA-B27 never develop the condition, and some people without the marker do develop it.

How Reiter's Disease Is Diagnosed

There is no single blood test or imaging study that confirms Reiter's disease. Diagnosis relies on recognizing the pattern of symptoms and ruling out other conditions that cause similar inflammation.

A doctor will ask about recent infections — whether you had diarrhea, urinary symptoms, or a sexually transmitted infection in the weeks before your joints became inflamed. They will examine your joints, eyes, and urinary tract for signs of inflammation. They may ask about skin rashes, mouth ulcers, or other symptoms.

Blood tests can support the diagnosis. Tests may show elevated inflammatory markers (such as erythrocyte sedimentation rate or C-reactive protein), indicating that inflammation is present. A test for HLA-B27 may be ordered, since carrying this genetic marker increases the likelihood of Reiter's disease, though it is not required for diagnosis. Blood cultures or tests for specific bacteria may be done to identify the triggering infection if it is still active.

X-rays or ultrasound of affected joints may show inflammation or, in chronic cases, damage to bone or cartilage. These imaging studies help rule out other forms of arthritis.

Because Reiter's disease resembles other conditions — including rheumatoid arthritis, lupus, and other reactive arthritis forms — a doctor may order additional tests to exclude those possibilities.

How Long Reiter's Disease Lasts and What Happens Next

Most people recover from Reiter's disease within three to twelve months. The joint inflammation gradually subsides, eye symptoms resolve, and urinary tract symptoms improve. Some people experience complete recovery with no lasting effects.

However, a significant portion of people develop chronic or recurrent symptoms. Roughly 15 to 50 percent of people (estimates vary) experience ongoing joint pain or stiffness months or years after the initial episode. Some develop permanent joint damage, particularly in the spine or feet. A small number have repeated episodes of Reiter's disease triggered by new infections.

The severity and duration of symptoms vary widely. Some people have mild inflammation that barely interferes with daily life, while others experience severe pain that limits movement and work. Factors that may influence the course include the severity of the initial infection, how quickly treatment begins, and individual genetic and immune factors.

People with HLA-B27 tend to have more severe or longer-lasting symptoms than those without the marker. Those with eye involvement may be at higher risk for chronic inflammation.

Treatment Approaches for Managing Symptoms

Treatment for Reiter's disease focuses on reducing inflammation and managing pain, since there is no cure that directly stops the condition. Most people do not require hospitalization.

Nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen or naproxen are typically the first treatment. These reduce joint pain and swelling. If NSAIDs alone are not sufficient, a doctor may prescribe stronger anti-inflammatory medications or corticosteroid injections directly into affected joints.

If the triggering bacterial infection is still active, antibiotics may be prescribed. However, antibiotics do not prevent or shorten Reiter's disease itself — they treat the underlying infection. Once the reactive arthritis has developed, the inflammation usually continues even after the infection is cleared.

For eye inflammation, topical corticosteroid drops or other eye medications may be prescribed. Severe eye inflammation may require oral corticosteroids or other immunosuppressive medications.

Physical therapy can help maintain joint mobility and prevent stiffness, particularly during the recovery phase. Rest and ice applied to swollen joints provide temporary relief.

In cases of severe or chronic inflammation that does not respond to standard treatments, doctors may prescribe disease-modifying antirheumatic drugs (DMARDs) or biologic medications that suppress immune activity. These are typically reserved for people with persistent symptoms.

Reiter's Disease Versus Other Forms of Reactive Arthritis

Reiter's disease is one form of reactive arthritis, but the terms are not interchangeable. Reactive arthritis is the broader category — it includes any joint inflammation triggered by an infection elsewhere in the body. Reiter's disease specifically refers to reactive arthritis with the classic triad of joint inflammation, eye inflammation, and urinary tract symptoms.

Some people develop reactive arthritis with only joint inflammation and no eye or urinary symptoms. Others have joint and eye inflammation but no urinary symptoms. These presentations are still reactive arthritis, but they would not be called Reiter's disease in the strict sense.

Reiter's disease is also distinct from rheumatoid arthritis, lupus, and other autoimmune conditions that cause chronic joint inflammation. Those conditions develop from the body's own immune system attacking joints over time, not from a reaction to a specific infection. Reiter's disease typically resolves or improves as the immune response to the triggering infection fades.

Frequently Asked Questions

Can you get Reiter's disease more than once?

Yes, though it is uncommon. Some people develop Reiter's disease after one infection and never experience it again. Others have recurrent episodes triggered by new infections with the same or different bacteria. People with HLA-B27 may be at higher risk for recurrence.

Is Reiter's disease contagious?

Reiter's disease itself is not contagious — you cannot catch it from someone who has it. However, the bacterial infection that triggers it may be contagious. For example, chlamydia or food-borne bacteria can spread to others, but those people would not necessarily develop Reiter's disease even if they caught the infection.

Does Reiter's disease cause permanent joint damage?

Most people recover without permanent damage. However, some people develop chronic inflammation or lasting joint changes, particularly in the spine, heels, or feet. Early treatment and managing inflammation may reduce the risk of long-term damage, though individual outcomes vary.

What is the difference between Reiter's disease and chlamydia arthritis?

Chlamydia arthritis is reactive arthritis triggered specifically by chlamydia infection. Reiter's disease can be triggered by chlamydia or other bacteria. The terms overlap — chlamydia arthritis is a type of reactive arthritis, and if it includes eye and urinary symptoms, it would be called Reiter's disease.

Can you have Reiter's disease without the eye symptoms?

Yes. While the classic triad includes joint, eye, and urinary symptoms, many people develop only one or two of these. Joint inflammation alone is the most common presentation. The condition is still reactive arthritis, though it may not be called Reiter's disease in the strict sense.
