Allergy is generally defined as the reaction of the body or one of its organs to an external stimulus. Some people have an abnormal reaction that results in a set of symptoms and signs that vary depending on the organ that is sensitive, for example:
Eye allergies result in symptoms such as burning, itching, and increased tearing
Allergic rhinitis results in symptoms such as sneezing, nasal itching, nasal congestion, and nasal congestion.
Chest allergy, which results in symptoms such as coughing, shortness of breath, and the appearance of chest congestion.
Digestive system allergy, the symptoms of which are diarrhea if the digestive system is sensitive, for example, to some type of food.
Many scientists consider that the appearance of headaches resulting from migraines is only one of the types of allergies to the head.
Skin allergies result in symptoms such as itching, redness, and rashes. In this topic, we will talk in detail about the types of skin allergies and methods of treating and preventing them.
What is the cause of allergic diseases?
Until now, science has not been able to provide a satisfactory answer about why some people are susceptible to sensitivity to certain substances and stimuli that result in known allergic diseases, while these substances do not affect other people. However, scientists have developed theories and factors that help the emergence of allergic diseases, and among these theories are The following factors:
They found that children who were breastfed were less susceptible to allergic diseases than children who were not breastfed.
They found that children who consumed foodstuffs such as bananas, egg whites, and cow’s milk in the months between four and eight years of age had an increase in allergic diseases. Therefore, there is a healthy scientific system for how to wean children, which depends first on not introducing other foodstuffs into the mother’s milk before they are fed. The child exceeds the fourth month of age, and after that, other foodstuffs will be introduced gradually, each type of food at an appropriate time. For example, meat, egg yolks, and fish are introduced after the child reaches the eighth month, while egg whites, cow’s milk, and bananas are introduced after the child reaches the age of one year. As for food items such as rice, potatoes, cerelac, vegetables, and fruits, they are introduced after the child reaches the fourth month of age, provided that they are introduced These foods gradually.
Scientists also found that allergic diseases increase in people who are most exposed to chemicals and industrial substances, such as people who work in factories or who live in places where there is increased pollution and gases emitted from factories and car exhausts.
There is a genetic and familial factor in the emergence of allergic diseases, such that their appearance increases in people who have a family history of the presence of these diseases among their family members and relatives.
