prematurely — before the expected time.

primary lactase deficiency — 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.

progesterone — 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.

progestin — 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.

Tay-Sachs disease — 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.

testicle (testis) — 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.

thalassemia — a group of blood diseases, that are inherited, which affect a person's hemoglobin and cause anemia. Hemoglobin is a protein in red blood cells that carries oxygen and nutrients to cells in the body.

tonsillitis — inflammation of the tonsils, which are lymph nodes in the back of the mouth at the top of the throat. Tonsils help to filter out bacteria and other microorganisms to prevent infection in the body. When they become overwhelmed by bacterial or viral infection they can become swollen and inflamed.

toxemia — see preeclampsia.

toxoplasmosis — an infection caused by the parasite named Toxoplasma gondii that can invade tissues and damage the brain, especially in a fetus and in a newborn baby. Symptoms include fever, fatigue, headache, swollen lymph glands, and muscle aches and pains. 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.

transient ischemic attack (TIA) — 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.

trichomoniasis — 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).

triple screen — blood test that indicates if there’s an increased risk of a birth defect, or a condition like Down Syndrome, in the fetus. This test can also show twins.

trisomy 18 — 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.

urinary tract infection — an infection anywhere in the urinary tract, or organs that collect and store urine and release it from your body (the kidneys, ureters, bladder, and urethra). An infection occurs when microorganisms, usually bacteria from the digestive tract, cling to the urethra (opening to the urinary tract) and begin to multiply.

uterine contractions — During the birthing process, a woman's uterus tightens, or contracts. Contractions can be strong and regular (meaning that they can happen every 5 minutes, every 3 minutes, and so on) during labor until the baby is delivered. Women can have contractions before labor starts; these are not regular and do not progress, or increase in intensity or duration.

uterine fibroids — common, benign (noncancerous) tumors that grow in the muscle of the uterus, or womb. Fibroids often cause no symptoms and need no treatment, and they usually shrink after menopause. But sometimes fibroids cause heavy bleeding or pain, and require treatment.
