a philosophy of giving birth developed by Dr. Ferdinand Lamaze. The goal of Lamaze classes is to increase women's confidence in their ability to give birth. Lamaze classes teach women simple coping strategies for labor, including focused breathing. But Lamaze also teaches that breathing techniques are just one of the many things that help women in labor. Movement, positioning, labor support, massage, relaxation, hydrotherapy and the use of heat and cold are some others.

a condition in which abnormal cells are found in the breast lobules. Since these cells have not spread outside the breast lobules, it's called "in situ," which means "in place." With LCIS, there are more abnormal cells in the lobule than with atypical hyperplasia. LCIS is not cancer, but having it increases breast cancer risk.
an analgesic is a drug that relieves pain. Pain-relieving drugs can be given to a woman during labor and delivery locally through a needle inserted into a muscle (intra-muscular) or under the skin (subcutaneous).

infection which causes inflammation of the membranes covering the brain and spinal cord.
replaces the hormones that a woman's ovaries stop making at the time of menopause, easing symptoms like hot flashes and vaginal dryness. It involves using man-made estrogen alone or estrogen with progestin, often in the form of a pill or skin patch. MHT used to be called hormone replacement therapy, or HRT. [A recent, large study found that use of MHT poses some serious risks, such as increasing some women's risk for breast cancer, heart disease, stroke, and pulmonary embolism (blood clot in the lung). Women who choose to use MHT should use the lowest dose that helps for the shortest time needed. Talk with your doctor to find out if MHT is right for you and discuss other ways to relieve menopause symptoms.]

a sudden illness caused by the virus paramyxovirus. It is spread by direct contact as well as by airborne droplets and saliva. Since 1967 the mumps vaccine (MMR, or measles, mumps and rubella) has helped cases decline in the United States. Symptoms include inflamed salivary glands (causing a child to have full cheeks like a chipmunk), inflamed tissues of the central nervous system (brain and spine), and an inflamed pancreas. Mumps in a child who has gone through adolescence tends to affect the ovary and the testes, which can lead to infertility.
necrotizing enterocolitis occurs when the lining of the intestinal wall dies and the tissue falls off.It mainly affects premature infants or sick newborns. The cause for this disorder is unknown. But it is thought that a decrease in blood flow to the bowel keeps the bowel from making mucus that protects the gastrointestinal tract. Bacteria in the intestine may also be a cause.
cells in the human body that are the building blocks of the nervous system (the system that records and transmits information chemically and electrically within a person). Nerve cells, or neurons, are made up of a nerve cell body and various extensions from the cell body that receive and transmit impulses from and to other nerves and muscles. Nerve tissue in the breast makes breasts sensitive to touch, allowing the baby's sucking to stimulate the let-down or milk-ejection reflex and milk production.
A major birth defect caused by abnormal development of the neural tube, or the structure in an embryo which develops into the brain and spinal cord. Neural tube defects are among the most common birth defects that cause infant death and serious disability. The most common neural tube defects are anencephaly, spina bifida, and encephalocele. In anencephaly the skull and most or all of the brain does not develop. Encephalocele is a hernia of part of the brain and of the membranes covering it. Spina bifida is an opening in the column encasing the spinal cord.

a bone disease that is characterized by progressive loss of bone density and thinning of bone tissue, causing bones to break easily.
cancer of the ovary or ovaries, which are organs in the female reproductive system that make eggs and hormones. Most ovarian cancers develop from the cells that cover the outer surface of the ovary, called epithelial cells.
health of the ovaries and eggs. It is an important factor in female fertility and decreases with age.
part of a woman's reproductive system, the ovaries produce her eggs. Each month, through the process called ovulation, the ovaries release eggs into the fallopian tubes, where they travel to the uterus, or womb. If an egg is fertilized by a man's sperm, a woman becomes pregnant and the egg grows and develops inside the uterus. If the egg is not fertilize, the egg and the lining of the uterus is shed during a woman's monthly menstrual period.
the release of a single egg from a follicle that developed in the ovary. It usually occurs regularly, around day 14 of a 28-day menstrual cycle.
a method used by couples trying to get pregnant, in which they have intercourse just before or after ovulation.
a hormone that increases during pregnancy and acts on the breast to help produce the milk-ejection reflex. Oxytocin also causes uterine contractions.
a feeling triggered in the nervous system. Pain may be sharp or dull. It may come and go, or it may be constant. Once it is treated, pain usually goes away. However, sometimes pain goes on for weeks, months or even years. This is called chronic pain.
a glandular organ located in the abdomen. It makes pancreatic juices, which contain enzymes that aid in digestion, and it produces several hormones, including insulin. The pancreas is surrounded by the stomach, intestines, and other organs.
an anxiety disorder in which a person suffers from sudden attacks of fear and panic. The attacks may occur without a known reason, but many times they are triggered by events or thoughts that produce fear in the person, such as taking an elevator or driving. Symptoms of the attacks include rapid heartbeat, chest sensations, shortness of breath, dizziness, tingling, and feeling anxious.

during this exam, the doctor or nurse practitioner looks for redness, swelling, discharge, or sores on the outside and inside of the vagina. A Pap test tests for cell changes on the cervix. The doctor or nurse practitioner will also put two fingers inside the vagina and press on the abdomen with the other hand to check for cysts or growths on the ovaries and uterus. STD tests may also be done.
an infection of the female reproductive organs that are above the cervix, such as the fallopian tubes and ovaries. It is the most common and serious problem caused by sexually transmitted diseases (STDs). PID can cause ectopic pregnancies, infertility, chronic pelvic pain, and other serious problems. Symptoms include fever, foul-smelling vaginal discharge, extreme pain, and vaginal bleeding.
a sore on the lining of the stomach or duodenum (beginning of the small intestine). Peptic ulcers are common — one in 10 Americans develops an ulcer at some time in his or her life. One cause of peptic ulcer is bacterial infection, but some ulcers are caused by long-term use of nonsteroidal anti-inflammatory agents (NSAIDs), like aspirin and ibuprofen. In a few cases, cancerous tumors in the stomach or pancreas can cause ulcers. Peptic ulcers are not caused by stress or eating spicy food.
the phase in a woman’s reproductive lifecycle leading up to menopause. Menopause is reached when a woman hasn’t had a period for 12 months in a row. Before that point, during perimenopause, a woman's body slowly makes less of the hormones estrogen and progesterone. This causes some women to have symptoms such as hot flashes and changes in their periods. Many women go through it in their 40s and 50s.

therapy aimed to restore movement, balance and coordination.
a small gland in the head that makes hormones that control other glands and many body functions including growth.
during pregnancy, a temporary organ joining the mother and fetus. The placenta transfers oxygen and nutrients from the mother to the fetus, and permits the release of carbon dioxide and waste products from the fetus. The placenta is expelled during the birth process with the fetal membranes.
when the placenta separates from the uterine wall before delivery, which can mean the fetus doesn’t get enough oxygen.
when the small milk ducts in the breast become blocked, or plugged. This is often caused by mastitis.
a severe inflammation of the lungs in which the alveoli, or tiny air sacs in the lungs, are filled with fluid. This may cause a decrease in the amount of oxygen that the blood can absorb from air breathed into the lung. Pneumonia is usually caused by infection but may also be caused by radiation treatment, allergy, or irritation of lung tissue by inhaled substances. It may involve part or all of the lungs.

also called premature birth, it is a birth that occurs before the 37th week of pregnancy.
labor that occurs before 37 completed weeks of pregnancy.
when a person is born with the inability to digest lactose, a sugar found in milk and milk products. Lactose can't be digested because there is not enough of an enzyme, called lactase, in the body. Consuming milk and dairy products causes diarrhea, bloating, gas, and discomfort. This deficiency can also develop over time, as the amount of lactase in the body decreases with age.
a reproductive health problems that occurs when a woman's ovaries stop working normally before she is 40. POI is not the same as early menopause. Some women with POI still get a period now and then. But ovulation problems can make getting pregnant hard for women with POI.
a female hormone produced by the ovaries. Progesterone, along with estrogen, prepares the uterus (womb) for a possible pregnancy each month and supports the fertilized egg if conception occurs. Progesterone also helps prepare the breasts for milk production and breastfeeding.
a hormone that works by causing changes in the uterus. When taken with the hormone estrogen, progestin works to prevent thickening of the lining of the uterus. This is helpful for women who are in menopause and are taking estrogen for their symptoms. Progestins also are prescribed to regulate the menstrual cycle, treat unusual stopping of the menstrual periods, help a pregnancy occur or maintain a pregnancy, or treat unusual or heavy bleeding of the uterus. They also can be used to prevent pregnancy, help treat cancer of the breast, kidney, or uterus, and help treat loss of appetite and severe weight or muscle loss.
a hormone that increases during pregnancy and breastfeeding. It stimulates the human breast to produce milk. Prolactin also helps inhibit ovulation.
a gland in a man's reproductive system. It makes and stores seminal fluid. This fluid is released to form part of semen.

a chronic (long-lasting) skin disease of scaling and inflammation that mostly affects adults. It occurs when skin cells quickly rise from their origin below the surface of the skin and pile up on the surface before they have a chance to mature. Usually this movement takes about a month, but in psoriasis it may occur in only a few days. Psoriasis results in patches of thick, red (inflamed) skin covered with silvery scales. These patches usually itch or feel sore, and most often occur on the elbows, knees, other parts of the legs, scalp, lower back, face, palms, and soles of the feet, but they can occur on skin anywhere on the body.
a doctor (M.D.) who treats mental illness. Psychiatrists must receive additional training and serve a supervised residency in their specialty. They can prescribe medications.
a clinical psychologist is a professional who treats mental illness, emotional disturbance, and behavior problems. They use talk therapy as treatment, and cannot prescribe medication. A clinical psychologist will have a master's degree (M.A.) or doctorate (Ph.D.) in psychology, and possibly more training in a specific type of therapy.
counseling or "talk" therapy with a qualified practitioner in which a person can explore difficult, and often painful, emotions and experiences, such as feelings of anxiety, depression, or trauma.

a protein found on most people's red blood cells. If you do not have the protein, you are Rh negative. Most pregnant women who are Rh negative need treatment to protect the fetus from getting a blood disease that can lead to anemia.
form of arthritis that causes pain, swelling, stiffness and loss of function in your joints. It can affect any joint but is common in the wrist and fingers. If one hand has RA, the other one usually does too. It’s an autoimmune disease. This means the arthritis is caused by your immune system attacking your body's own tissues. RA can affect body parts besides joints, such as your eyes, mouth and lungs.
a reflex that newborn babies have, along with the reflexes for sucking and swallowing. Rooting means turning the head to search for the nipple and milk.

sexual advances (like touching, grabbing) or sexual comments (that can be offensive and/or joking) that are not wanted or appropriate. This can happen in the workplace and a person can feel like they have no control over it. They may decide not to deal with it because they fear they will lose their job or not get a raise or promotion.
see sexually transmitted infections (STIs).
diseases that are spread by sexual activity. Also called sexually transmitted diseases (STDs).
a disease that occurs when the same virus that causes chicken pox becomes active again. After a person has chicken pox, the virus stays in the body. It may not cause problems for many years. As a person gets older, the virus may come back as shingles. It can cause mild to severe pain, usually on one side of the body or face. Unlike chicken pox, you can’t catch shingles from someone who has it. A vaccine can prevent shingles or lessen its effects. The vaccine is for people 60 and older.
a blood disorder passed down from parents to children. It involves problems in the red blood cells. Normal red blood cells are round and smooth and move through blood vessels easily. Sickle cells are hard and have a curved edge. These cells cannot squeeze through small blood vessels. They block the organs from getting blood. Your body destroys sickle red cells quickly, but it can't make new red blood cells fast enough — a condition called anemia.
a disorder involving brief interruptions of breathing during sleep.
an anxiety disorder in which a person feels overwhelming anxiety and excessive self-consciousness in everyday social situations. It can be limited to only one type of situation, such as a fear of speaking in formal and informal situations, or eating or drinking in front of others.

This damage includes paralysis (not being able to move or feel a part of the body), numbness, blindness, dementia, and even death.
an autoimmune disease that can cause inflammation and damage to the joints, skin, kidneys, heart, lungs, blood vessels, and brain.
buildup of plaque, a filmy substance, on the teeth.
a fatal genetic disorder in which harmful quantities of a fatty substance called ganglioside GM2 build up in the nerve cells in the brain and damage the cells. In children, this begins in the fetus early in pregnancy. By the time a child with Tay-Sachs is three or four years old, the nervous system is so badly affected that death usually results by age five.
the male sex gland. There are a pair of testes behind the penis in a pouch of skin called the scrotum. The testes make and store sperm, and make the male hormone testosterone.

Can be contracted by touching the hands to the mouth after gardening, cleaning a cat's litter box, or anything that came into contact with cat feces; or by eating raw or partly cooked meat, or touching the hands to the mouth after touching raw or undercooked meat.
a type of unsaturated fat. Foods made with partially hydrogenated or hydrogenated oils contain trans fat. Food manufacturers use trans fat to prolong the shelf life of processed food. Some trans fats occur naturally in meat and dairy products from animals such as cattle, goats, and sheep. Eating trans fats increases the risk of certain long-term illnesses, such as coronary artery disease.
a "mini-stroke" where there is a short-term reduction in blood flow to the brain usually resulting in temporary stoke symptoms. Does not cause damage to the brain, but puts a person at higher risk of having a full stroke.)
a brain injury that results from a sudden blow to the head. Symptoms may be mild, moderate or serious, depending on the extent of damage.
a very common STD in both women and men that is caused by a parasite that is passed from one person to another during sexual contact. It also can be passed through contact with damp, moist objects such as towels or wet clothing. Symptoms include yellow, green, or gray vaginal discharge (often foamy) with a strong odor; discomfort during sex and when urinating; irritation and itching of the genital area; or lower abdominal pain (rare).
a type of fat in the blood stream and fat tissue. High triglyceride levels (above 200) can contribute to the hardening and narrowing of arteries.

a condition in which a baby is conceived with three copies instead of the normal two copies of chromosome #18. Children with this condition have multiple malformations and mental retardation due to the extra chromosome #18. Some of the problems include: low birth weight, small head, small jaw, malformations of the heart and kidneys, clenched fists with abnormal finger positioning, and malformed feet. The mental retardation is severe. Ninety five percent of children with this condition die before their first birthday.
a disease caused by bacteria that usually affects your lungs. Tuberculosis (TB) bacteria is spread through the air from one person to another. If someone with TB of the lungs or throat coughs or sneezes, people nearby who breathe in the bacteria can get TB. If your body can't stop the bacteria from growing, you will develop TB disease.
an abnormal mass of tissue that results when cells divide more than they should or do not die when they should. Tumors can be benign or malignant. Benign tumors are not cancer. Malignant tumors are cancer.
a painless, harmless test that uses sound waves to produce images of the organs and structures of the body on a screen. Also called sonography.
connected to the placenta and provides the transfer of nutrients and waste between the woman and the fetus.
includes both polyunsaturated and monounsaturated fats. Found mainly in nuts, seeds, many fish, and oils from plants, unsaturated fat helps your body to work well and may also lower your blood cholesterol level when used in place of saturated fat and trans fat.
the tube that carries urine from the kidney to the bladder. You have two ureters, one for each kidney.
the tube that releases urine from the body.
a chemical created when the body breaks down substances called purines. Purines are found in some foods and drinks, such as liver, anchovies, mackerel, dried beans and peas, beer, and wine. Most uric acid dissolves in blood and passes out of the body in urine. If your body produces too much uric acid or doesn't remove enough of it, you can get sick.

during the birthing process, a woman's uterus tightens, or contracts.
