Anemia in Adolescents
To understand what is anemia one should begin with breathing. The oxygen that is inhaled simply doesn’t stop in lungs. It circulates though out the body and fuels the brains also. Oxygen travels to all parts of the body though bloodstream and to be precise in the RBCs I.e. red blood cells. Now, these RBCs are produced in the bone marrow of the body and they serve as boats carrying oxygen in the bloodstream. RBCs have something called hemoglobin, a protein which holds oxygen. To make adequate hemoglobin body requires iron in plenty. The iron is supplied by the foods that we take along with other nutrients. When these RBCs are fewer in number than what is needed anemia occurs in the body. There can be 3 primary reasons: RBCs are lost due to some reason, the production of RBCs is slower than what is needed and lastly the body is destroying the RBCs. Different types of anemia are linked to at least one of these causes.
The bone marrow replaces small amounts of blood is lost due to some reason without making a person anemic. But in cases where considerable amount of blood flows in small amount of time as a result of an injury due to a serious example for instance, it may not be possible for bone marrow to replace RBCs so quickly resulting in anemia. Also, losing small amounts of blood over long periods of time may also lead to anemia. Example of this situation can be seen in girls who get heavy periods attributed mainly to deficiency of iron in the diet.
Anemia due to iron deficiency is the most common kind of anemia in the United States. It occurs mainly due to lack of iron in a person’s diet. A teen with iron deficiency would have lower hemoglobin production and consequently lower RBCs. When the production of RBCs is low the person is regarded as anemic. The signs of anemia are paleness and tiredness. There can be other reasons as to why enough RBCs are not produced in the body. Folic acid and Vitamin B-12 are also essential to produce RBCs. Getting these in adequate quantities is this important too. There can be a problem with bone marrow’s working too resulting in anemia.
Hemolytic anemia occurs when a person has RBCs whose lifespan is shorter. The bone marrow may not be able to produce new blood cells if the blood cells die too early. This can result due to many reasons including person having disorders like sphenocytosis or sickle cell anemia. In some cases the immune system of the body may itself destroy the RBCs. In some cases certain antibodies can form in the blood as a result of reaction to certain drugs or infections and may attack the RBCs.
Teens get anemia as they grow rapidly the amount of iron intake may not be enough to keep up with the pace of the growth as it needs more nutrients in this process. In the case of girls they need more iron after puberty and are at risk due to heavy blood loss during menstrual periods. In some cases pregnancies also leads to anemia. Also, teens who diet excessively to lose weight may also be at risk of having iron deficiency. Meat eaters especially red meat eaters are at less risk compared to vegetarians as meat has rich iron in it.
Allergies in Adolescents
Allergies are reactions by immune system that are abnormal in nature to stuff that are usually harmless to majority of the people. When somebody is allergic to something the immune system of that person gets confused and thinks that the substance is detrimental to the body. The substances causing allergic reactions are known as allergens. The examples of allergens are dust, food, plant pollen, medicine etc. The body produces antibodies to protect itself from these allergens. The antibodies make certain cells present in the system to let chemicals to mix with the bloodstream and one of them is histamine. This chemical then acts on nose, eyes, skin, lungs, gastrointestinal tract and results in allergic reaction symptoms. Exposure to the same chemicals in future triggers same response to the antibodies again meaning every time one comes in contact with the same allergen, allergic reaction is produced in the body.
Allergic reactions can range from mild symptoms like runny nose to more severe ones such as difficulty in breathing. Teenagers suffering from asthma often have allergic reaction to cold and get asthma attack is another example of allergies. Some kinds of allergies trigger multiple symptoms. Allergic reactions in very rare cases also produce severe reaction known as “anaphylaxis” for which the signs are difficulty in breathing, difficulty in swallowing, swelling in tongue, lips and throat and dizziness. This allergic reaction occurs as soon as the system is exposed to substances that trigger allergic reactions like peanut although some reactions are delayed by as much as four hours.
The reasons why people get allergies can be various and one of the reasons could be hereditary but that that does not necessarily mean that children are bound to get allergies from their parents. Some of the common allergens include food, airborne particles, insect bite and sting, medicines, chemicals etc. Food allergies typically occur in infants and usually vanish as the child grows. The list of food allergens includes milk & dairy products, wheat, soy, eggs, peanuts, and seafood. Some people are allergic to stings and bites of certain insects. The venom in the bite is the one which actually causes reaction and can be as serious as anaphylactic in some teens. Some teens are also allergic to airborne particles which are also known as environmental allergens. They are also the commonest of all the allergens. Examples of these allergens include dust mites, animal dander, mold spores, grass pollens, trees and ragweed. Some adolescents are also allergic to certain antibiotic medicines. Another common allergen is chemical, certain chemicals present in laundry detergents or cosmetics can cause rashes that are itchy in nature.
Allergists usually treat allergic problems. They may ask questions like symptoms of the allergy and whether it is hereditary. They may also prescribe certain diagnostic tests like blood or skin test depending on the type of allergy. The best way to treat allergies is to completely avoid the substances that cause allergies. However there are certain medications and injections are also available to treat allergies.
One can follow certain things to avoid allergies like people who have food allergies that contain should peanuts and any food containing smallest amount of peanuts. Also avoid using cosmetic that contain chemicals allergic to the skin. One can also avoid airborne allergies by keeping pets in restricted areas and away from bedroom. Replace carpets and rugs from time to time. Avoid keeping things that accumulate dust. And also clean the room and house frequently.
Adolescent Pregnancy
Adolescent pregnancy in ninety nine percent of the cases is unwanted and is the major consequence of adolescent sexual activity, other than STDs. This issue has affected youth, families, educators, health care professionals, and government official. A study on the high school adolescents has concluded that forty eight percent of the males and forty five percent of the females are sexually active. One fourth of the high school students had sexual contact by fifteen years of age. The average age of boys is sixteen and a girl is seventeen, who have had intercourse. Ninety percent of adolescents, in the age range of fifteen to nineteen, say their pregnancy is unintended.
Seventy four percent of females above fourteen years and sixty percent of females below fifteen years have reported to have involuntary sex. Fifty percent of the adolescent pregnancies are within the time period of six months after the initial sexual intercourse. More than nine hundred thousand teenagers are reported to have become pregnant every year in the United States. Fifty one percent of the adolescent pregnancies result in live birth, thirty five percent result in induced abortion and fourteen percent result in stillbirths or miscarriages. Four out of ten adolescent females get pregnant, before they turn twenty, at least once. Twenty five percent of adolescent deliveries aren’t the mother’s first child. When a teenager gives birth to her first child, she increases the risk of begetting another child. One third of the adolescent parents are themselves result of adolescent pregnancies.
There are many reasons why adolescents choose to become sexually active at an early stage in life. The reasons can be early pubertal development, poverty, sexual abuse in childhood, lack of parent’s attention, lack of career goals, family and cultural patterns of early sex, substance abuse, dropping out from school and poor school performance. Factors which discourage an adolescent to become sexually active are stable family environment, parental supervision, good family income, regular prayers, connectedness with parents and living with complete family and both the parents. The factors which are responsible for the consistent use of contraceptive among adolescents are academic success, anticipation for successful future, and involvement in a stable relationship.
There are many medical risks associated with adolescent pregnancies. Adolescents who are less than seventeen years are at a greater risk of developing medical complications, when compared to adult females. The risk is even more in teenagers below seventeen. The weight of the child, given birth by an adolescent, is very low in these pregnancies. It is usually below 2.5 kilogram. The rate of neonatal birth is also three times greater in adolescents, when compared to adults. Other problems caused by adolescent pregnancies are prematurity of the child, birth of underweight child, poor maternal weight gain, poor nutritional status, anemia, STDs and hypertension induced due to pregnancy.
Although there is an increase in the use of contraceptive methods by adolescents during their first sexual contact, only sixty three percent of the high school students have said to use condom while having sex previously. Adolescents, who use prescription contraceptives, delay their doctor’s visit until the time they become sexually active for over a year.
According to a research, youngsters who have participated in sex education programs which gave them knowledge about contraception methods, abstinence, sexually transmitted diseases and youngsters who involved in discussions in order to get a clear picture, used contraceptives and condoms effectively without any increase in sexual activity. The Center for Disease Control & Prevention has said that the solution for unwanted adolescent pregnancies and STDs are barrier contraceptive use and abstinence.
