Your DNA raw data from ancestry genetic testing service providers like 23andMe, AncestryDNA, Family Tree DNA (FTDNA), Living DNA, My Heritage can be used to get personalized and actionable recommendations to prevent allergic reactions.
Cockroaches are nocturnal insects and they come out during the night to feed. The protein present in the body parts of cockroaches, their saliva and their waste trigger allergies. They live in drain pipes and in all types of houses and buildings. Nearly 60% of houses contain cockroach allergens, so there is year-long exposure to these allergens. People of certain genetic types are at a higher risk of being allergic to cockroaches.
Milk allergy occurs when the body's immune system recognizes milk proteins as foreign and mounts an immune response. The symptoms of milk allergy usually begins within a few minutes to a few hours after consumption of milk. This type of food allergy is identified during infanthood but most children with milk allergy normally outgrow it. People of certain genetic types are at a higher risk of being allergic to milk.
Hay fever may be triggered by many allergens including pet allergens and pollen grains. This type of allergy gets its name from incidents of a stuffy nose, nasal congestion, itchy eyes and watery eyes while harvesting fields. People of certain genetic types are at a higher risk of having hay fever and may experience the following symptoms: runny nose and other symptoms similar to a common cold but with red and itchy eyes.
Dust mite allergy
Dust mites are extremely small creatures, belonging to the same family as spiders and ticks, and found in many homes. According to the Asthma and allergy foundation of America, dust mites are one of the most common triggers for year round allergy. Dust mites feed on human skin that is shed every day, on an average 1.5 kg of human skin is shed by every human. The flakes of skin may be present on furniture, bedding and even on toys.
Lactose intolerance is a condition in which there is decreased ability to digest lactose, a sugar present in milk. People of certain genetic types stop producing lactase during adulthood, an enzyme needed to breakdown lactose and may experience the following symptoms: abdominal cramps, bloating, nausea, fatigue or diarrhoea.
Pollen allergy is one of the leading causes of hay fever. The immune system of the host recognizes pollen grain as foreign and mounts a strong reaction which is exhibited as classic symptoms of pollen allergy. People of certain genetic types are at a higher risk of being allergic to pollens and may experience the following symptoms: an asthma attack, conjunctivitis or a stuffy nose
According to American Academy of Allergy Asthma and Immunology, 62% of households in the US have pets. Animal protein from skin cells, waste, hair and saliva could trigger an allergic reaction, known as pet allergy. Pets tend to shed dead skin and hair which can accumulate in all corners of the house. People of certain genetic types are at a higher risk of being allergic to pets and may experience the following symptoms: sniffling, itchiness, sneezing and watery eyes.
Nearly 3 million people in the U.S. have peanut and tree nut allergy. A study by researchers from Mount Sinai School of Medicine(New York) has shown that genes account for 81.6% of the risk for peanut allergies. The symptoms of peanut allergy are triggered with even the slightest of exposure.People of certain genetic types are at a higher risk of being allergic to peanuts and may experience the following symptoms: an itchy mouth, a tingling sensation runny nose, congestion or anaphylaxis.
Grass allergy is very common as grass pollens scatter in the wind, which is different from other pollens that are transmitted by insects. This increases the risk of these allergens being inhaled. Grass pollen is released during late spring and early summer. People of certain genetic types are at a higher risk of being allergic to grass and may experience the following symptoms: itchy eyes, stuffy nose and a cough.
Tree Nut Allergy
Tree nut allergy is a hypersensitive immune reaction towards tree nuts and edible tree seeds. walnuts, cashew nuts, almonds, lychee nuts, pistachios or pecans could trigger an allergy. People of certain genetic types are at a higher risk of being allergic to tree nuts and may experience the following symptoms: asthma, itchy throat, skin rashes, swollen eyes, diarrhea, difficulty in swallowing and shortness of breath.
Egg allergy occurs when the body’s immune system recognizes egg protein as foreign and mounts an immune reaction. The symptoms of egg allergy usually begin within a few hours of consuming egg and this allergy is most common among children. However, most children outgrow this allergy. People of certain genetic types are at a higher risk of beng allergic to eggs.
Histamine intolerance occurs when the functions of the histamine N-methyltransferase (HNMT) and histamine-degrading enzyme diamine oxidase (DAO) are impaired. Histamine is produced by the body during a local immune response and is a neurotransmitter. It is present in our stomach, skin and lungs. In typical individuals, excess of histamine is degraded rapidly but when this degradation is affected, it leads to histamine intolerance.
