With the onslaught of pollen and dust in spring, allergies are high and many people suffer from allergy symptoms, but can allergies heal themselves? Can allergies be hereditary? Do you know these cold knowledge about allergy? Here, Alopah will answer all of them.
Can allergies heal themselves?
When it comes to the question of whether allergies can heal on their own, it depends on what the specific disease is. For common hives, acute hives, many people may have them once or twice in their life, and they will heal themselves with or without medication, because it is a state of susceptibility and it is something that can heal on its own. But the common atopic dermatitis, for example, can last for the rest of a person’s life, from infancy to childhood, to adolescence, to adulthood, and even to old age. This disease is not self-healing and requires long-term management and medication.
Do allergies run in families?
Do not think that dermatitis can be inherited dermatitis, because our skin includes the body system, your parents may show allergic rhinitis, but you may show the state of dermatitis, the state of asthma, etc. For example, the most common symptoms of atopic dermatitis we just mentioned are food allergy and dermatitis in infants, and a little bit older, asthma may occur in children, and allergic rhinitis may occur in adolescents, and this is the atopic process of it. Therefore, it is important to look at the heredity of allergies systematically. It cannot be said that dermatitis is hereditary, but the hereditary quality of allergies can occur, but there are different diseases.
Are allergies contagious?
Allergic diseases, our common urticaria, dermatitis, eczema, including also some drug allergies, are not contagious.
Do allergies occur when allergic substances such as pollen and dust are inhaled into the nasal cavity?
When we inhale (group) allergies, the first to be affected is our nasal mucosa, which can develop allergic rhinitis, sneezing and runny nose; and the eye mucosa, which can have symptoms such as itchy eyes or conjunctival congestion and tearing; our respiratory tract can also have symptoms such as cough and asthma. This is the inhalation group of allergies. In addition to inhalation allergies, there are also skin contact allergies. When we come in contact with an allergen, it will give us a contact allergy. So allergy is not just through respiratory allergy, but also contact with the skin can cause allergy.
Why do people who were not allergic to seafood, beef and mutton and other allergenic substances suddenly become allergic?
Because the state of the human organism is constantly changing, and so is the state of various immune systems. Our human organism will slowly age, and our life and environment are constantly changing, which will lead to changes in the human system and state. As an example, it is the same as when we get sick everyday. It is the same thing when a person who has never had allergies suddenly becomes allergic. Through a change in the immune environment and immune status of the body in a certain state, a substance that was harmless to you suddenly overreacts with your own body, and you become allergic. This is an immunological mechanism that occurs, but the cause is not particularly clear.
Some people believe that allergic reactions are a sign of increased immunity, while others believe that allergies are due to poor resistance.
Because the human organism is a very large and balanced organ, we have a lot of self-antigens, and we slowly develop tolerance to some of our own antigens, but allergies are actually not very related to increased immunity. Some people think that it is because my immunity and resistance is weak that I have allergies. It is true that when our immunity is weak, our resistance can be combined with other diseases, such as colds and flu. The human body does not live in a sterile environment, nor is it a hood. It will come into contact with different things, including viruses, bacteria, fungi and other harmful substances from outside. Therefore, allergy is not an enhanced or weakened immune system, but it has a lot to do with genetic allergy quality and the state of the human organism.
