Overview
Polycystic Ovary Syndrome
Polycystic ovary syndrome (PCOS) is a common hormonal and metabolic disorder that can affect ovulation, menstrual cycles, androgen levels, and metabolism. People with PCOS may have irregular or absent periods, difficulty becoming pregnant, increased facial or body hair, acne, or thinning scalp hair. Some also have insulin resistance or increased risk of metabolic problems. The exact cause is not fully understood, but genetic and hormonal factors appear to contribute. Symptoms vary considerably, and diagnosis is based on the overall clinical picture rather than a single test.
Allergic Rhinitis
Allergic rhinitis is a group of symptoms affecting the nose and often the eyes after exposure to substances that trigger an allergic response. Common triggers include pollen, dust, mold and animal dander. Seasonal allergic rhinitis, commonly called hay fever, is often caused by pollen from trees, grasses or ragweed. Symptoms can include sneezing, itching, runny or stuffy nose, watery eyes, reduced sense of smell and throat irritation.

Diagnosis
Polycystic Ovary Syndrome
PCOS is diagnosed from the overall clinical picture because there is no single definitive test. Evaluation commonly includes a history of menstrual patterns, symptoms of androgen excess, physical examination, and selected blood tests. Pregnancy and other conditions that can cause irregular periods or androgen-related symptoms may need to be excluded. Pelvic ultrasound may be used to assess ovarian morphology when appropriate, but polycystic-appearing ovaries are not required for diagnosis in every diagnostic framework. Metabolic assessment may also be recommended.
Allergic Rhinitis
Diagnosis is based on symptoms, medical history and physical examination. The healthcare provider may ask when symptoms occur, whether they vary by season and whether they are associated with exposure to pets, dust or other allergens. Allergy testing can identify specific triggers. Skin testing is commonly used, while blood tests measuring allergy-related antibodies may be used when skin testing is not appropriate. An eosinophil count may also provide supporting information in some cases.
Prevention
Polycystic Ovary Syndrome
PCOS cannot currently be prevented in every individual because its underlying causes are complex and include genetic and hormonal factors. Maintaining regular physical activity, a balanced diet, and a healthy body weight where appropriate can support metabolic health and may improve some PCOS-related features. Early evaluation of persistent irregular periods, excessive hair growth, acne, or fertility difficulties can help identify the condition and associated metabolic risks. Regular monitoring can help address complications such as abnormal glucose regulation and cardiovascular risk.
Allergic Rhinitis
Symptoms can sometimes be prevented or reduced by avoiding the allergens that trigger them. During pollen season, people with hay fever may benefit from staying indoors when pollen levels are high, keeping windows closed and using air conditioning when possible. Reducing exposure to known household allergens can also help. Identifying triggers through allergy testing may make avoidance strategies more effective. People with persistent symptoms should discuss appropriate preventive treatment with a healthcare provider.
Risk Factors
Polycystic Ovary Syndrome
Factors associated with PCOS include a family history of the condition, insulin resistance, excess body weight, and metabolic abnormalities, although PCOS can occur in people of different body sizes. The condition commonly becomes apparent around puberty or during the reproductive years. Some individuals have a higher risk of related metabolic problems, including impaired glucose regulation and abnormal cholesterol levels. Symptoms and risk factors vary, and the presence of one feature does not by itself establish a diagnosis.
Allergic Rhinitis
Risk factors include a personal or family history of allergies, repeated exposure to pollen, dust mites, mold or animal dander, and living or working in environments where these allergens are common. Seasonal exposure is particularly important for hay fever. The amount of pollen in the air can influence symptoms, with higher pollen levels often occurring on hot, dry and windy days. People with other allergic conditions may also be more likely to develop allergic rhinitis.
