1. Hypersensitivity Revealed
There is a great chance that everyone may acquire food allergies and food intolerances. Some
individuals often wonder why they experience unpleasant reactions after ingesting some types of food.
This is because many people are unaware that they have food allergies.
There is one out of three people who claim that either they have acquired food allergy or a family
member is suspected to have food allergy that is why they tend to modify their diet. Among children, 5%
are diagnosed of having food allergies. About 4% of the teen and adult populations are being diagnosed
of having allergies to food.
The perception of the public to the problem and the clinically proven cases of food allergy are altered.
This is because there is a misconception of the difference of food allergies and food intolerance. A food
allergy is characterized by the body's hypersensitivity to a certain type of food. The immune system
releases histamine that causes an allergic response. Food intolerance and food allergy may have similar
symptoms. However, the immune system is only responsible for the symptoms of allergy to food. For
example, milk allergy and lactose intolerance may share similar symptoms. However, the former is
characterized by an adverse reaction of the body due to milk, and the former is the inability to absorb or
digest milk.
Pollen Allergies Facts
These round or oval pollen grains used by plants for reproduction are tiny so that it cannot be seen by
the naked eye In some species, the plant uses the pollen from its own flowers to fertilize itself. Other
types of plants should be pollinated with others of their own species.
In order for the plant’s fertilization to take place and for the seeds to form, the pollen must be
transferred from the flower of one plant to that of another of the same species; thus cross-pollination.
For some flowering plants, insects do the job of pollination. For some, it is carried by the wind. Plain-
looking plants such as trees, grasses, and weeds; the ones that do not have showy flowers, are the types

2. of pollen that commonly cause allergic reactions. The pollens produced by these plants have to be
suitable for air transport, therefore they must be small, light, dry.
Vaccine Allergy
Although it is not a common response that the body be allergic to vaccine, it can still cause anaphylaxis.
There is a one in a million chance for an allergic reaction due to vaccination to develop. Before deciding
between getting vaccinated or not, take note of the dangers of skipping a vaccination. Mumps and
measles are both reported to have caused death. Children may be required by their schools to get
vaccinated. Moreover, parents may also protect their children from acquiring these conditions.
In this case, what can become potential triggers that may be acquired in the vaccine? Egg protein and
gelatin are considered to be the main ingredients in vaccines. In fact, flu and yellow vaccine contains egg
protein. Varicella, Japanese encephalitis, Mumps, Measles, and Rubella vaccine contains gelatin. The use
of thimerosal as preservative for vaccines has been stopped in the U.S. This was done after it was
discovered that it can trigger allergic reactions to several individuals.
Allergy Overview
There are symptoms that a person is experiencing allergies and these include wheezing, coughing,
rashes, itchy eyes, and runny nose. How a person experiences the symptoms depends on the allergen
and how he was exposed to it.
For instance, an individual may experience difficulty in breathing if he inhales pollen grains or skin rashes
if he applies a certain type of lotion which contains some of the chemicals he is allergic to, or nausea and

3. vomiting if he eats something he is allergic to. Some people inherit their allergies from their family
members. You are said to have atopic allergy if this happens. Babies who have low birth weight are more
likely to inherit allergies. On the other hand, boys are also said to be more likely to inherit the condition
than girls. Mild, moderate, and severe are the levels of allergic reactions.
There are cases that are life threatening. This is what is referred to as anaphylaxis. Being a medical
emergency, anaphylaxis must be attended to right away.
Cigarette Smoke Allergy
Research shows that respiratory infections and asthma are
higher in the family smoking individuals. According to
research, a child growing in a family of smokers has a higher
tendency to develop respiratory infections and asthma. An
individual suffering from a smoke allergy is more sensitive
to smoke than others.
People suffering from cigarette smoke allergy may be easily
affected than others. A number of toxic chemicals and
irritants are present in a cigarette smoke. Bronchitis and
sinusitis are allergic complications. Exposure to secondhand
smoke increases the risk of experiencing complications.
