Some individuals are highly sensitive to eucalyptus pollen. A reaction might arise if exposed to the pollen while outdoors. Take note that the allergy symptoms are likely to manifest during the peak of its reproductive season. On the other hand, odor reactions to the eucalyptus leaves and essential oils can arise any time.
If an individual inhale the eucalyptus pollen, it causes the immune system in some individuals to release chemicals that are responsible for the allergy symptoms.
Directly handling the oily leaves or bark of the tree might also instigate symptoms that often start with itchiness. The inflammation of the mucous membranes results to sensations of itchiness. In some cases, an itchy mouth, nose and throat might arise after exposure.
Once the mucous membranes of the eyes are affected by the eucalyptus pollen, the symptoms of allergic conjunctivitis arises.
The eyes start to turn red and become watery. The itchiness often spreads to the eyes and might become more intense if the individual rubs them. Take note that the inflammation triggered by hay fever can also cause the eyelids to become swollen or darkened circles form under the eyes.
The inflammation and increased production of mucus and drainage that occurs with hay fever can disrupt the respiratory system.
Individuals who breathe in the eucalyptus pollen might end up with swelling in the throat and nasal passages as the body tries to get rid of the allergens. Sneezing occurs to clear the irritants in the throat and nasal membranes.
These respiratory symptoms can cause difficulty breathing. A runny nose might alternate with congestion until exposure to the allergen ends.
Fatigue and pain
If the individual suffers from prolonged allergic reactions, it can take its toll on overall health. The swelling of the airways as well as irritation due to mucus drainage can cause dry cough and sore throat.
The pressure brought about by sinus congestion and inflammation results to facial pain, headaches and tenderness. A lengthy or severe allergy can cause the individual to feel tired even after the other symptoms have settled.
