Overview

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.
Asthma
Asthma is a chronic condition in which the airways become inflamed and can narrow or become more sensitive to triggers. This may cause repeated episodes of wheezing, coughing, chest tightness, or shortness of breath. Symptoms can vary over time and may become worse during an asthma attack. Asthma can begin in childhood or adulthood and affects people of all ages.

Diagnosis

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.
Asthma
Asthma is diagnosed using the pattern of symptoms, medical history, physical examination, and lung function testing. Spirometry can assess how much air a person can breathe out and how quickly it moves through the airways. Additional testing may be used when the diagnosis is uncertain or to identify allergic or other triggers. Symptoms and lung function are considered together.

Prevention

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.
Asthma
Asthma cannot always be prevented, but attacks can often be reduced by identifying and avoiding personal triggers and following an individualized treatment plan. Avoiding tobacco smoke, reducing exposure to known allergens or irritants, managing respiratory infections, and taking prescribed medicines as directed can help control symptoms. Regular follow-up is important when symptoms are persistent or changing.

Risk Factors

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.
Asthma
Risk factors include a family history of asthma, allergies, exposure to tobacco smoke, certain workplace chemicals or dusts, repeated viral respiratory infections during childhood, and obesity. The likelihood of asthma may also be influenced by environmental conditions and individual sensitivity to allergens or irritants. Risk factors and triggers differ between people.
