Causes Of Allergic Reactions And Allergy Symptoms
The most common allergens are those that affect our respiratory system, such as pollen and dust mites. In this article, we will tell you more about the most common causes of allergic reactions, as well as the most common allergy symptoms.
According to current estimates, about one in four people suffers from some degree of allergy throughout their lives. In fact, it is the most common disease in children.
What are the most common causes of allergic reactions?
The causes of allergic symptoms are caused by symptoms caused by a substance, either in the respiratory system, digestive system, nervous system or on the skin. In other words, it is an abnormal reaction of our body’s resistance to a substance that should not normally cause such a reaction.
In general, a person can be allergic to virtually any substance.
What does it mean to be allergic to someone?
The body’s resistance works constantly, identifying and protecting the body from harmful factors and bacteria, to protect the body from various diseases. Sometimes, however, it may be too active.
When the body’s own resistance begins to overreact to certain stimuli that are normally harmless to humans, an allergic reaction occurs. In other words, the body activates several defense mechanisms after being exposed to a particular substance, causing symptoms such as sneezing.
This is often the case, for example, with pollen.
Allergy symptoms vary depending on the substance to which the person is allergic. If you are allergic to dust mites, the person is most likely to suffer from respiratory allergy symptoms. In other words, the person then suffers e.g. coughing, sneezing, and bleeding eyes.
The most common allergy symptoms
As we mentioned earlier, allergy symptoms depend on the type of allergy in question. Similarly, reactions depend on the route through which the allergen has been exposed.
This means that the causes of allergic reactions affect the symptoms they cause – whether you have been exposed to the allergen by eating, touching or inhaling an allergen.
Therefore, the most common allergy symptoms are rhinitis and allergic conjunctivitis. The runny nose causes itching in the nose, sneezing, nasal congestion, and constant watery discharge from the nose.
Allergic conjunctivitis, in turn, causes severe itching of the eyes, followed by constant bleeding of the eyes. In addition, people who suffer from it sometimes feel like they have sand in their eyes.
However, the most common allergens are related to the respiratory system.
It is also important to mention that allergic symptoms are often associated with asthma. Asthmatics often suffer from coughing, wheezing, and difficulty breathing.
Food allergies
When a person is allergic to a food, the most common allergy symptoms are itchy mouth and a nasty tingling that can reach all the way to the throat. In some cases, symptoms also include swelling of the lips, tongue, or even the entire facial area.
Urticaria may also occur later. In addition, in some cases, food allergy symptoms may include diarrhea, vomiting, and persistent flatulence.
The most common foods that cause allergy symptoms are milk, nuts, and eggs.
Drug allergies
Many people are allergic to a particular drug. Physicians should always ask the patient if this is potentially allergic to any medication. Symptoms of this type of allergy usually include skin symptoms such as hives, other rashes, and itchy skin.
Anaphylaxis
Anaphylaxis is a serious reaction that occurs when the allergic reaction is very strong. Then the body’s resistance secretes substances into the body that cause a sudden drop in blood pressure. This in turn leads to narrowing of the airways, making breathing difficult.
Anafylaxis can occur very suddenly when a person is exposed to an allergen. For example, it is quite common in people who are allergic to wasp stings.
When someone suffers from an anaphylactic reaction, his heart rate accelerates and he becomes weak. In addition to difficulty breathing, symptoms may include rash, nausea, or vomiting. In these cases, it is important to seek emergency care.
Conclusion
Many people are allergic to several different substances. Therefore, it is important to know the most common allergy symptoms. In this way, you can, if necessary, guide your doctor to understand what has caused the allergy and to avoid the cause of the allergy yourself.
