Overview

Rheumatoid Arthritis
Rheumatoid arthritis is a chronic autoimmune disease that primarily causes inflammation of the joints. The immune system mistakenly attacks tissues around the joints, leading to pain, swelling, stiffness and reduced movement. It often affects the hands, wrists and feet symmetrically, but can involve other joints and organs. Persistent inflammation can damage joints and affect overall health.
Anal Fistula
An anal fistula is an abnormal tunnel that develops between the inside of the anus or rectum and the skin near the anus. It often develops after an infection or abscess in an anal gland. Symptoms may include persistent drainage, pain, swelling, irritation, or recurrent abscesses around the anus.

Diagnosis

Rheumatoid Arthritis
Diagnosis is based on symptoms, physical examination, blood tests and imaging. Blood tests may measure rheumatoid factor and anti-CCP antibodies and assess inflammation. X-rays, ultrasound or MRI can show joint inflammation or damage. No single test confirms rheumatoid arthritis in every person, so the overall clinical picture is considered.
Anal Fistula
An anal fistula is diagnosed through a medical history and examination of the anus and surrounding skin. The healthcare professional may look for an external opening, drainage, swelling, or tenderness. A digital rectal examination may help identify the tract. Imaging such as MRI or ultrasound may be used when the fistula is complex, recurrent, or difficult to identify during examination.

Prevention

Rheumatoid Arthritis
Rheumatoid arthritis cannot always be prevented because genetic and immune factors contribute to its development. Avoiding tobacco use is an important way to reduce risk. Maintaining a healthy weight and addressing other modifiable health factors may also be beneficial. Early medical evaluation of persistent joint swelling and stiffness allows appropriate treatment to begin before significant joint damage develops.
Anal Fistula
Preventing anal fistula mainly involves reducing the risk of anal abscesses and treating infections promptly. People with inflammatory bowel disease should follow appropriate medical treatment and monitoring. Persistent pain, swelling, drainage, or recurrent abscesses around the anus should be evaluated by a healthcare professional rather than left untreated.

Risk Factors

Rheumatoid Arthritis
Risk factors include having certain genetic traits, being female, increasing age and having a family history of rheumatoid arthritis. Smoking is an important modifiable risk factor. Obesity and some environmental exposures may also contribute. The disease can occur in people without any known risk factor.
Anal Fistula
Risk factors include a previous anal abscess, inflammatory bowel disease such as Crohn disease, recurrent infections in the anal region, previous anal or rectal surgery, and conditions that interfere with normal healing or immunity. A history of an anal fistula also increases the likelihood of recurrence.
