Overview

Thyroiditis
Thyroiditis is inflammation of the thyroid gland. Different forms can cause temporary release of thyroid hormones followed by low thyroid hormone levels, while other forms may cause persistent changes in thyroid function. Symptoms therefore vary and may include neck pain or tenderness, fatigue, changes in heart rate, heat or cold intolerance, weight changes, or symptoms of an underactive thyroid.
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

Thyroiditis
Diagnosis begins with symptoms, medical history, and examination of the thyroid gland. Blood tests can measure thyroid-stimulating hormone and thyroid hormone levels and may include tests for thyroid antibodies. Depending on the suspected type, a healthcare provider may use an ultrasound or other thyroid imaging and, in selected cases, tests of thyroid hormone uptake. The pattern of thyroid function over time can help distinguish different forms of thyroiditis.
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

Thyroiditis
Thyroiditis cannot always be prevented because many forms are related to autoimmune processes, viral illnesses, or other factors that cannot be controlled. Appropriate management of underlying autoimmune or medical conditions and review of medicines that may affect the thyroid can help reduce complications. People who develop persistent symptoms of abnormal thyroid function should seek medical evaluation and follow recommended monitoring.
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

Thyroiditis
Risk factors depend on the type of thyroiditis. A recent viral illness may precede subacute thyroiditis, while autoimmune thyroid disorders are associated with other immune-related conditions and family history. Postpartum thyroiditis can occur after pregnancy. Some medicines and treatments can also affect the thyroid and contribute to inflammation or changes in thyroid function.
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.
