Symptoms of an Allergy
An allergic reaction begins when an allergen enters the body, triggering an antibody response. When the allergen comes into contact with the antibodies, these cells respond by releasing certain substances including histamine. These substances cause the symptoms. The symptoms of an Allergy are like an alarm signal, warning that something is wrong.
Common symptoms associated with allergic conditions include:
- sinus pain
- runny nose
- nettle rash / hives
- itchy eyes, ears, lips throat and mouth
- shortness of breath
- sickness, vomiting & diarrhea
- increase in nasal and airway secretions
Sneezing helps clearing the airways from substances identified as harmful. This is associated to allergic disorders such as rhinitis, hay fever and anaphylaxis.
It is an alarm signal warning that something is going wrong in our nose.
A nasal blockage can happen when there is an obstruction due to mucus secretion, to the inflammation of the nose or to the growth of nasal polyps.
The mucus in the nose is necessary to catch and neutralize harmful. The mucus in the nose can be liquid or thick, transparent or colored.
It is due to the flow of liquid from the blood vessels to the deeper layers of the skin.
It is an alarm signal, warning that something is going wrong in our eyes.
Dilation of blood vessels in the surface of the eyeballs leads to eye redness.
Coughing helps to clear the airways from secretions or foreign particles such as allergens and microbes.
The feeling of a pressure of the chest, that causes difficult breathing. You feel that sensation, if the airways are narrowed and the air cannot pass easily.
Shortness of breath or breathlessness
It is associated to disorders such as asthma and anaphylaxis. It is difficult to inhale or exhale air. It is a warning signal. You can have this feeling if you try to breathe through a straw.
Nasal congestion or the blockage of mucus secretion in the sinuses can lead to headache.
It is often associated to allergic disorders such as food allergy and anaphylaxis. Food that has not been digested or an accelerated transit of the food in the bowels can lead to liquid stools.
When the digestive system is not functioning correctly you feel a pain in the belly, often associated to vomiting or diarrhea.
Vomiting has the objective of getting rid of a content that the organism identifies as harmful. It occurs at allergic disorders such as food allergy and anaphylaxis.
When the air passes through a narrowed or obstructed airway a whistling sound is produced during breathing. This is called “wheezing”. This is associated with asthma.
It is often associated to atopic dermatitis or contact dermatitis. Skin redness appears, when the blood vessels are dilated due to harmful stimuli.
It is always a signal that something is wrong. Receptors in the skin are stimulated and are the cause, why we want to scrape us. (atopic dermatitis, contact dermatitis)
IMPORTANT: Any of these symptoms can be caused by other conditions, none of these symptoms are exclusive of allergy and some of them can be very serious. If you suffer from them we recommend you to visit a doctor.
