[…] trees) season defined by pollen counts, birch pollen allergens are present in the air. 52, 53 These atmospheric allergens may induce allergic rhinitis symptoms, but more research is needed to confirm this hypothesis. [onlinelibrary.wiley.com]
The research presented here did not identify any birch trees in which Bet ν 1 variants with a high IgE-reactivity are reduced in abundance or are absent. [library.wur.nl]

Most common symptoms of a reaction are: Itchy, tingly mouth, lips, or throat Very mild swelling of the lips, tongue, or throat Watery, itchy eyes, runny nose, sneezing Some people develop itching, redness, or slight swelling of the hands if they peel [chkd.org]
AVOID THE DANGER FOODS Around half will suffer an itching and/or swelling in the lips or tongue from eating celery Certain ‘healthy’ foods can cause people with hay fever to suffer other effects too, says Professor Stephen Durham, head of allergy and [dailymail.co.uk]
Swelling of the lips, tongue, and uvula, and a sensation of tightness in the throat may be observed. [en.wikipedia.org]
If, for example, you have a birch pollen allergy and eat raw apple or pear, you may experience a localized allergic reaction with mild swelling and itchiness inside your mouth. [jaxallergy.com]
More severe reactions may include dysphagia or throat swelling, but patients may also experience systemic reactions such as urticaria, rhinitis, or anaphylaxis. 58, 66 Thus, the initial general designation “oral allergy syndrome” for this phenomenon is [onlinelibrary.wiley.com]
- Inflammation
inflammation varies with the pollen season. [ncbi.nlm.nih.gov]
The discomfort can be due to inflammation, post-nasal drip or both. Depending on how much you’re coughing, you could also develop laryngitis and hoarseness. [jaxallergy.com]
- Asymptomatic
Patients without GI symptoms (NS-group) In asymptomatic patients there was no correlation between the degree of intestinal inflammation and the reactivity to PR-10 proteins. [ncbi.nlm.nih.gov]
Respiratoric
- Rhinitis
Birch pollen is the most dominant tree pollen in Northern and Central Europe and is a major cause of allergic rhinitis and, possibly, asthma symptoms. [onlinelibrary.wiley.com]
Antihistamines and allergy shots for allergic rhinitis/hay fever may sometimes help prevent or reduce symptoms associated with Oral Allergy Syndrome. [chkd.org]
Pollen of the European white birch (Betula pendula) is a considerable cause of hay fever (seasonal allergic rhinitis) in northern and central Europe. [library.wur.nl]
There are a number of studies that found that patients with allergic rhinitis or chronic sinusitis who use regular saline rinses have less bacterial load and require fewer antibiotics. [jaxallergy.com]

Sneezing and congestion. You may sneeze frequently, have an itchy nose, and feel pressure in your nose and sinuses. Coughing fits or sore throats. Allergies to tree pollen may also cause you to experience a scratchy, sore throat. [jaxallergy.com]
The overall odds ratio of having allergic rhinitis symptoms at age 8 or 16 years in children with Bet v 1 sensitization at age 4 was 7.1 (95% CI, 3.3‐15.3). 76 Symptoms associated with birch pollen allergy include nasal symptoms such as rhinorrhea, sneezing [onlinelibrary.wiley.com]

Neurologic
- Headache
Those who have more than 14 drinks a week are 78 per cent more likely to develop the sore eyes, runny nose and headaches associated with reactions to house dust mites or animal fur. [dailymail.co.uk]
- Confusion
Often well-cooked, canned, pasteurized, or frozen food offenders cause little to no reaction due to denaturation of the cross-reacting proteins, [7] causing delay and confusion in diagnosis as the symptoms are elicited only to the raw or fully ripened [en.wikipedia.org]
Treatment
Also, allergic symptoms are common during the treatment until tolerance is built. We want to make the treatment more efficient, less time-consuming, safe and patient-friendly. [desentum.fi]
The treatment has to be prescribed by an allergy specialist and it can take a few months to get referred. The best results are seen four months after treatment begins, says Professor Durham. [dailymail.co.uk]
It’s common to ignore allergy symptoms, especially if you do not know enough about the available treatment options. But, for many, pollen allergy can be more than just a minor inconvenience. [alk.net]

Another option is nasal air filters — clear, soft rubbery implants worn outdoors to prevent allergens from being inhaled. [dailymail.co.uk]
Consequently, prevention of birch pollen allergy and OAS would contribute to an improvement of the quality of life of many patients. [library.wur.nl]
