Illness and Disability
Medical terms
 All those new, confusing words could be enough to drive you crazy. It can really
be tough to hear your doctors say things you don’t understand. This is especially
true if they are in a hurry and don’t have time to explain things to you right
away. To help make you more comfortable, use the links below to get to the definitions.
You’ll be an expert in “doctor speak” in no time!
Here are some medical words in alphabetical order that you might be hearing:
AIDS (say: ayds) = This disease hurts the immune system, the
body’s way of protecting itself, so that it becomes easy to get dangerous infections
and cancers. It is caused by the HIV infection.
Albinism (say: al-byn-is-em) = A group of conditions that
cause a problem with your body’s ability to make melanin, which is the
pigment (color) of your skin, hair and eyes. This can make the skin and hair
look very white.
Allergies (say: al-ur-jee) = When someone has an allergic
reaction to something, the body’s protective immune system gives off a much bigger response than it normally
would. The result is to have a reaction, such as sneezing or trouble breathing,
to things that are usually not harmful, such as certain foods or animals.
Analgesics (say: ah-nuhl-jee-zicks) = Analgesics are meant
to relieve pain. These pain relievers don't get rid of what causes your pain,
they block the nerve pathways that send pain signals from the body part to the
brain so that you don't hurt as much.
Anemia (say: uh-nee-mee-uh) = When there are less red blood
cells in the blood, it can cause health problems. This is measured by a decrease
in what is called hemoglobin, which makes blood red in color and moves oxygen
through the body. There are many different types of anemia.
Anorexia nervosa (say: an-or-eck-see-ah nur-vo-sah) = An eating
disorder causes people to refuse to stay at a healthy body weight by not eating.
People with anorexia have a fear of gaining weight and a picture of what their
body looks like in their mind that is not what it really is.
Antibiotic (say: an-ty-by-ah-tiks ) = Antibiotics fight bacterial
infections by killing bacteria or stopping it from growing. Antibiotics can
help your body’s immune system fight off infections. If you have ever
had strep throat, your doctor probably gave you an antibiotic to take.
Antibodies (say: an-ty-bod-ees) = Proteins produced by white
blood cells to fight bacteria, viruses, and other foreign substances.
Arteries (say: ar-tuh-reez) = Thick-walled blood vessels that
carry blood away from the heart to other parts of the body.

makes it hard for people to pay attention and concentrate.

wheeze, feel shortness of breath, cough and feel a tightness in your chest.
Autism (say: ah-tiz-em) = A disorder in the brain that affects both
verbal and nonverbal communication (speaking and non-speaking) skills.
Bone marrow (say: bone mair-oh) = Soft tissue found inside bones from

multiply. There are at least 200 different kinds of cancers, which can grow in almost any
organ.
Capillaries (say: kap-il-air-eez) = Tiny blood vessels that branch
through body tissues to deliver oxygen and nutrients and carry away waste products.
Carbon dioxide (say: kar-bun dy-ocks-ide) = A body waste product that
is a colorless gas.
Celiac disease (say: see-lee-ack diz-eez) = When the small
intestine is hurt from eating gluten and other substances like it. Glutens are
found in wheat, rye, oats, barley and other grains.
Cerebral Palsy (say: se-reeb-rul pahl-zee) = When injuries
to the brain cause damage to the nerves and loss of movement. The injuries happen
while a baby is growing in the womb or near the time the baby is born.
Chemotherapy (say: key-mo-ther-uh-pee) = Chemotherapy is often known as chemo, a term used for medicines to treat cancer. Cancer happens when cells in the body develop wrong and grow in an uncontrolled way. Since cancer cells tend to divide very fast, chemotherapy works by getting in the way of these cells dividing and trying to stop the cancer from spreading. Sometimes chemo can cure the disease by helping to get rid of all the cancer cells in the body.
Chronic Fatigue Syndrome (say: kron-ick fah-teeg) = A very severe and
long-term feeling of weakness and being tired, even after getting rest.
Circulatory system (say: sur-kue-la-tor-ee sis-tem) = The heart, the
blood, and the system of blood vessels that moves blood through the body.
Cleft lip and palate (say: kleft lip and pal-it) = Abnormal growth of
the lip and or roof of the mouth that happens before a baby is born. This can affect the
way the lip looks, and also cause problems feeding as an infant and learning to speak.
Clotting (say: klod-ing) = When the body forms a plug
to seal damaged blood vessels and stop bleeding.
Cystic Fibrosis (say: sis-tick fy-broh-sis) = A disease that causes
both breathing and digesting problems. Cystic fibrosis runs in the family.

red blood cells, which helps the blood carry and deliver oxygen to body tissues.
Hemophilia (say: heem-o-feel-ee-ah) = A disease that makes
