Hay cold, that so?
The summer spring season often coincides with allergies: this is the case of hay, Also known as allergic rhinitis, which has symptoms similar to common cold:
- a runny nose
- nasal obstruction
- itching intra nasal
Other symptoms that can accompany hay cold cold
Other symptoms that can accompany these, are: headache, loss of the sense of the smell, eye symptoms such as excessive tearing, itching or eye redness.
The cause must be sought in external or internal allergens such as pollen, dust mites or animal hair which cause the allergy.
Specifically, in the predisposed subjects (it is estimated that 1 person out of 5 is affected), the immune system considers harmful to the substances that are normally harmless, producing specific antibodies (IGE) to fight them.
The IgE in turn bind to other cells of the immune system, the mastocytes, which release large quantities of histamine, a substance that causes the dilation of the arterial capillaries, induces the secretion of watery mucus, stimulates nerve endings causing the sensation of itching and sneeze.
Finally, it recalls the blood plasma in the tissues and thus causes the edema of the affected part.
The symptoms can then extend throughout the year or manifest themselves only in some periods (spring, summer, autumn).
If you suffer from these symptoms and suspect you have hay fever, it is advisable to visit the allergist specialist who, on the basis of the symptoms, medical history and allergy tests (on the skin or on the blood), will carry out the diagnosis and will prescribe drug therapy (antihistamines, nasal sprays, eye drops) to keep symptoms under control.
Eventually an allergen-specific immunotherapy will also be prescribed to obtain a clinical benefit and to prevent any complications.
In fact, not correctly treated, hay colds can lead to complications such as sinusitis,#8217; otitis media and the evolution of allergic disease up to the appearance of bronchial asthma.
