A Breakdown of the Symptoms of Nut Allergies
There are many people who suffer from nut allergies, both children and adults. While some people only suffer with a mild rash or a bit of facial swelling, there are others who have immune systems that overreact severely not only to nuts, but to any food that they may be allergic to. Symptoms can begin within minutes of consuming an offending food or within hours. Whether symptoms that present themselves are mild or life threatening, the amount of people with nut allergies continues to increase across the country.
Nut allergies are present when the body over reacts to something that is harmless to others that are not allergic to nuts. When a person comes in contact with something that they are allergic to, the cells in the body release histamine. This makes the tiny blood vessels in the tissues of the body leak fluids, causing them to swell. Depending on the severity of the nut allergies, the swelling can affect only the lips a little bit or the entire airway of a person, sometimes sending them into cardiac arrest.
There is no cure for nut allergies, and the only way to avoid reactions is to avoid the offending nuts. If someone who has nut allergies does come into contact with them and a reaction starts, treating it quickly will help minimize the potentially serious risks to the person. If the person has a severe allergic reaction, if it is available, they should be given an adrenaline injection right away, and 911 should be called. Other than peanuts, some of the most common nuts that can cause a nut allergy are hazelnuts, walnuts, cashews, pecans, Brazil nuts, and pistachios.
With nut allergies, when a person comes into contact with nuts for the first time in their lives, the immune system reacts and prepares to fight. In this initial meeting with nuts, there is no reaction! It is during the second exposure to nuts that we see a reaction. Children usually already have come in contact with nuts through the mother while still in the womb or from breast milk as infants. The sensitivity that people have to nuts varies greatly; while one person can handle and be near nuts and have no reaction, others cannot even get the nut oils on their hands without going into anaphylactic shock. Difficulty breathing, swelling of the lips, face, and hands, rashes, sweating, and dizziness are some of the most common symptoms of nut allergies.
