Overview

Hay Fever
Hay fever, also called pollen allergy or seasonal allergic rhinitis, occurs when the immune system reacts to airborne allergens such as pollen. It commonly causes sneezing, a runny or blocked nose, itching of the eyes, nose or throat, watery eyes, coughing, and postnasal drainage. Symptoms may occur during seasons when trees, grasses, or weeds release pollen into the air.
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

Hay Fever
Hay fever is usually diagnosed from the pattern of symptoms, their seasonal timing, and a physical examination. The healthcare provider may examine the nose, eyes, throat, and other areas affected by allergies. When the specific allergen is unclear or symptoms are difficult to control, allergy testing may be performed using skin tests or blood tests to identify relevant triggers.
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

Hay Fever
Hay fever symptoms can be reduced by limiting exposure to pollen and other known allergens. During periods of high pollen, keeping windows closed, reducing outdoor exposure, and changing clothes after spending time outside may help. Showering can remove pollen from the skin and hair. Saline nasal rinsing may also help clear allergens, but sterile, distilled, or properly treated water should be used.
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

Hay Fever
The likelihood of hay fever is higher in people who have allergies or a family history of allergic conditions. Repeated exposure to pollen and other environmental allergens can trigger symptoms. Seasonal pollen levels, geographic location, and outdoor exposure influence when symptoms occur. People with other allergic diseases may also be more likely to experience allergic rhinitis.
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.
