This is how the Blood Type Diet can help. The body's response to allergens can be mediated by reducing overall stress on the body. Atopic asthma is more common in children, but most asthma sufferers have a combination of both types. Intrinsic asthma is caused by cold air, infections, inhaled irritants, exercise or emotional distress. Both of these conditions are worsened when allergies increase mucus in the nose.Įxtrinsic asthma, also called atopic asthma, is directly related to allergens and IgE reactions. Ear infections can occur when the Eustachian tube is not properly drained and pathogens take root. Sinusitis can occur when excess mucus in the sinus cavity is not properly drained and harmful bacteria or fungi grow out of control. This is why an EpiPen is carried by many with severe food allergies - in case accidental exposure to an allergen causes the throat to close rapidly.Īllergies can lead to complications like sinusitis, asthma, or ear infections. True food allergies usually cause symptoms within two hours, though some can happen in less than two minutes. Food sensitivities or intolerances don't create IgE cells, but can still cause digestive or mood problems and can increase the body's allergic response to other substances. Each species' pollen is slightly different, so it's possible to be allergic to the pollen from one specific plant but not another or to be allergic to many of them at once.įood allergies can cause hives, digestive problems, eczema and respiratory reactions. It is typically smaller than the width of a human hair and carried by the wind from one plant to another. Pollen is the egg-shaped male reproductive cell of flowering plants.

Antihistamines suppress allergy symptoms because histamine is the chemical responsible for them.Įnvironmental allergies can be caused by pollen, animal dander, smoke or chemicals, such as air fresheners or pollution.

Once created, the IgE cells can last for months, immediately releasing histamine and causing symptoms whenever an offending substance is eaten or inhaled. Immune cells called Immunoglobulin E (IgE for short) are created by the body in response to specific allergens. But when there's no actual threat to the body and it falsely sets off these countermeasures, the normally helpful symptoms serve no purpose and become disruptive. Allergy means 'altered working.' Watery eyes and a runny nose are great to wash away germs when your body is fighting a virus.
