Pregnancy: Preeclampsia and Eclampsia Glossary of Terms

The following are health and medical definitions of terms that appear in the Pregnancy: Preeclampsia and Eclampsia article.

Abdominal: Relating to the abdomen, the belly, that part of the body that contains all of the structures between the chest and the pelvis. The abdomen is separated anatomically from the chest by the diaphragm, the powerful muscle spanning the body cavity below the lungs.
See the entire definition of Abdominal

Abdominal pain: Pain in the belly (the abdomen). Abdominal pain can come from conditions affecting a variety of organs. The abdomen is an anatomical area that is bounded by the lower margin of the ribs above, the pelvic bone (pubic ramus) below, and the flanks on each side. Although abdominal pain can arise from the tissues of the abdominal wall that surround the abdominal cavity (the skin and abdominal wall muscles), the term abdominal pain generally is used to describe pain originating from organs within the abdominal cavity (from beneath the skin and muscles). These organs include the stomach, small intestine, colon, liver, gallbladder, and pancreas.

Antihypertensive: Something that reduces high blood pressure (hypertension).

Arthritis: Inflammation of a joint. When joints are inflamed they can develop stiffness, warmth, swelling, redness and pain. There are over 100 types of arthritis. (see osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, lupus, gout, pseudogout).

Blood in the urine: Blood in the urine is termed hematuria.

Blood pressure: The blood pressure is the pressure of the blood within the arteries. It is produced primarily by the contraction of the heart muscle. It's measurement is recorded by two numbers. The first (systolic pressure) is measured after the heart contracts and is highest. The second (diastolic pressure) is measured before the heart contracts and lowest. A blood pressure cuff is used to measure the pressure. Elevation of blood pressure is called "hypertension".

Cerebral: Pertaining to the brain, the cerebrum or the intellect.
See the entire definition of Cerebral

Cerebral palsy: An abnormality of motor function (the ability to move and control movements) that is acquired at an early age, usually less than a year of age, and is due to a brain lesion that is non-progressive. Cerebral palsy (CP) is frequently the result of abnormalities that occur in utero, while the fetus is developing inside the mother's womb. Such abnormalities may include accidents of brain development, genetic disorders, stroke due to abnormal blood vessels or blood clots, or infection of the brain. In rare instances, obstetrical accidents during particularly difficult deliveries can cause brain damage and result in CP. CP may be divided into spastic, choreoathetoid, and hypotonic (flaccid) CP. In spastic CP, there is an abnormality of muscle tone in which one or more extremities (arm or leg) is held in a rigid posture. Choreoathetoid CP is associated with abnormal, uncontrollable, writhing movements of the arms and/or legs. The child with hypotonic CP appears floppy -- like a rag doll. Treatment may include casting and braces to prevent further loss of limb function, speech therapy, physical therapy, occupational therapy, the use of augmentative communication devices, and the use of medications of botox injections to treat spasticity.

Chronic: This important term in medicine comes from the Greek chronos, time and means lasting a long time.
See the entire definition of Chronic

Coma: A state of deep unarousable unconsciousness.
See the entire definition of Coma

Cure: 1. To heal, to make well, to restore to good health. Cures are easy to claim and, all too often, difficult to confirm.
2. A time without recurrence of a disease so that the risk of recurrence is small, as in the 5-year cure rate for malignant melanoma.
3. Particularly in the past, a course of treatment. For example, take a cure at a spa.
See the entire definition of Cure

Diabetes: Refers to diabetes mellitus or, less often, to diabetes insipidus. Diabetes mellitus and diabetes insipidus share the name "diabetes" because they are both conditions characterized by excessive urination (polyuria).
See the entire definition of Diabetes

Dizziness: Painless head discomfort with many possible causes including disturbances of vision, the brain, balance (vestibular) system of the inner ear, and gastrointestinal system. Dizziness is a medically indistinct term which laypersons use to describe a variety of conditions ranging from lightheadedness, unsteadiness to vertigo.
See the entire definition of Dizziness

Eclampsia: Convulsions (seizures) occurring with pregnancy-associated high blood pressure and having no other cause.

Epilepsy (seizure disorder): When nerve cells in the brain fire electrical impulses at a rate of up to four times higher than normal, this causes a sort of electrical storm in the brain, known as a seizure. A pattern of repeated seizures is referred to as epilepsy. Known causes include head injuries, brain tumors, lead poisoning, maldevelopment of the brain, genetic and infectious illnesses. But in fully half of cases, no cause can be found. Medication controls seizures for the majority of patients.

Fetal distress: Compromise of the fetus during the antepartum period (before labor) or intrapartum period (birth process). The term "fetal distress" is commonly used to describe fetal hypoxia (low oxygen levels in the fetus). The concern with fetal hypoxia is it may result in fetal damage or death if not reversed or if the fetus is not promptly delivered.
See the entire definition of Fetal distress

Gestation: Period of time from conception to birth.

Gynecology: The branch of medicine particularly concerned with the health of the female organs of reproduction and diseases thereof.
See the entire definition of Gynecology

High blood pressure: Also known as hypertension, high blood pressure is, by definition, a repeatedly elevated blood pressure exceeding 140 over 90 mmHg -- a systolic pressure above 140 with a diastolic pressure above 90.
See the entire definition of High blood pressure

Hypertension: High blood pressure, defined as a repeatedly elevated blood pressure exceeding 140 over 90 mmHg -- a systolic pressure above 140 with a diastolic pressure above 90.
See the entire definition of Hypertension

Kidney: One of a pair of organs located in the right and left side of the abdomen which clear "poisons" from the blood, regulate acid concentration and maintain water balance in the body by excreting urine. The kidneys are part of the urinary tract. The urine then passes through connecting tubes called "ureters" into the bladder. The bladder stores the urine until it is released during urination.


See the entire definition of Kidney

Labor: Childbirth, the aptly-named experience of delivering the baby and placenta from the uterus to the vagina to the outside world. There are two stages of labor. During the first stage (called the stage of dilatation), the cervix dilates fully to a diameter of about 10 cm. In the second stage (called the stage of expulsion), the baby moves out through the cervix and vagina to be born.
See the entire definition of Labor

Lupus: A chronic inflammatory condition caused by an autoimmune disease. An autoimmune disease occurs when the body's tissues are attacked by its own immune system. Patients with lupus have unusual antibodies in their blood that are targeted against their own body tissues.
See the entire definition of Lupus

Magnesium: A mineral involved in many processes in the body including nerve signaling, the building of healthy bones, and normal muscle contraction. About 350 enzymes are known to depend on magnesium.
See the entire definition of Magnesium

Nausea: Nausea, is the urge to vomit. It can be brought by many causes including, systemic illnesses, such as influenza, medications, pain, and inner ear disease. When nausea and/or vomiting are persistent, or when they are accompanied by other severe symptoms such as abdominal pain, jaundice, fever, or bleeding, a physician should be consulted.

Nutrition: 1) The science or practice of taking in and utilizing foods. 2) A nourishing substance, such as nutritional solutions delivered to hospitalized patients via an IV or IG tube.

Obesity: The state of being well above one's normal weight.
See the entire definition of Obesity

Obstetrics: The art and science of managing pregnancy, labor and the puerperium (the time after delivery).

Pain: An unpleasant sensation that can range from mild, localized discomfort to agony. Pain has both physical and emotional components. The physical part of pain results from nerve stimulation. Pain may be contained to a discrete area, as in an injury, or it can be more diffuse, as in disorders like fibromyalgia. Pain is mediated by specific nerve fibers that carry the pain impulses to the brain where their conscious appreciation may be modified by many factors.
See the entire definition of Pain

Palsy: Paralysis, generally partial, whereby a local body area is incapable of voluntary movement (motor function). For example, Bell's palsy is localized paralysis of the muscles on one side of the face. The word "palsy" is a corruption (and contracture) of the French word "paralysie" which means "paralysis."

Placenta: 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. It is roughly disk-shaped, and at full term measures about seven inches in diameter and a bit less than two inches thick. The upper surface of the placenta is smooth, while the under surface is rough. The placenta is rich in blood vessels.
See the entire definition of Placenta

Preeclampsia: A condition in pregnancy characterized by abrupt hypertension (a sharp rise in blood pressure), albuminuria (leakage of large amounts of the protein albumin into the urine) and edema (swelling) of the hands, feet, and face. Preeclampsia is the most common complication of pregnancy. It affects about 5% of pregnancies. It occurs in the third trimester (the last third) of pregnancy.
See the entire definition of Preeclampsia

Pregnancy: The state of carrying a developing embryo or fetus within the female body. This condition can be indicated by positive results on an over-the-counter urine test, and confirmed through a blood test, ultrasound, detection of fetal heartbeat, or an X-ray. Pregnancy lasts for about nine months, measured from the date of the woman's last menstrual period (LMP). It is conventionally divided into three trimesters, each roughly three months long.
See the entire definition of Pregnancy

Pregnant: The state of carrying a developing fetus within the body.
See the entire definition of Pregnant

Protein: A large molecule composed of one or more chains of amino acids in a specific order determined by the base sequence of nucleotides in the DNA coding for the protein.
See the entire definition of Protein

Rheumatoid arthritis: An autoimmune disease which causes chronic inflammation of the joints, the tissue around the joints, as well as other organs in the body. Autoimmune diseases occur when the body tissues are mistakenly attacked by its own immune system. The immune system is a complex organization of cells and antibodies designed normally to "seek and destroy" invaders of the body, particularly infections. Patients with these diseases have antibodies in their blood which target their own body tissues, where they can be associated with inflammation. Because it can affect multiple other organs of the body, rheumatoid arthritis is referred to as a systemic illness and is sometimes called rheumatoid disease. While rheumatoid arthritis is a chronic illness (meaning it can last for years) patients may experience long periods without symptoms.
See the entire definition of Rheumatoid arthritis

Toxemia: A condition in pregnancy, also known as pre-eclampsia (or preeclampsia) characterized by abrupt hypertension (a sharp rise in blood pressure), albuminuria (leakage of large amounts of the protein albumin into the urine) and edema (swelling) of the hands, feet, and face. Pre-eclampsia is the most common complication of pregnancy. It affects about 5% of pregnancies. It occurs in the third trimester (the last third) of pregnancy.
See the entire definition of Toxemia

Urine: Liquid waste. The urine is a clear, transparent fluid. It normally has an amber color. The average amount of urine excreted in 24 hours is from 40 to 60 ounces (about 1,200 cubic centimeters). Chemically, the urine is mainly an aqueous (watery) solution of salt (sodium chloride) and substances called urea and uric acid. Normally, it contains about 960 parts of water to 40 parts of solid matter. Abnormally, it may contain sugar (in diabetes), albumen (a protein) (as in some forms of kidney disease), bile pigments (as in jaundice), or abnormal quantities of one or another of its normal components.

Uterus: The uterus (womb) is a hollow, pear-shaped organ located in a woman's lower abdomen between the bladder and the rectum. The narrow, lower portion of the uterus is the cervix; the broader, upper part is the corpus. The corpus is made up of two layers of tissue.

  • Related Diseases & Conditions

    • High Blood Pressure
      • High blood pressure, also known as hypertension, is a repeatedly elevated blood pressure exceeding 140 over 90 mmHg -- a systolic pressure above 140 with a diastolic pressure above 90. There are two causes of high blood pressure, primary and secondary. Primary high blood pressure is much more common that secondary and its basic causes or underlying defects are not always known. It is known that a diet high in salt increases the risk for high blood pressure, as well as high cholesterol. Genetic factors are also a primary cause. Secondary high blood pressure is generally caused by another condition such as renal hypertension, tumors, and other conditions. Treatment for high blood pressure is generally lifestyle changes and if necessary, diet.
    • Pregnancy (Stages - Trimesters of Pregnancy)
      • There are many symptoms involved in the 1st, 2nd and 3rd trimesters of pregnancy. The first early pregnancy symptom is typically a missed period, but others include breast swelling and tenderness, nausea and sometimes vomiting, fatigue and bloating. Second trimester symptoms include backache, weight gain, itching, and possible stretch marks. Third trimester symptoms are additional weight gain, heartburn, hemorrhoids, swelling of the ankles, fingers, and face, breast tenderness, and trouble sleeping. Read more to learn about recommended procedures and tests for each stage of a healthy pregnancy.
    • Edema
      • Edema is the swelling of tissues as a result of excess water accumulations. Peripheral edema occurs in the feet and legs. There are two types of edema, non-pitting edema and pitting edema. Causes of pitting edema is caused by systemic diseases, most commonly involving the heart, liver, and kidneys. Local conditions that cause edema are thrombophlebitis and varicose veins. Edema is generally treated with medication.
    • Pregnancy Symptoms
      • Pregnancy symptoms vary from woman to woman. There are some symptoms that are more frequent in some women. These symptoms include a missed period, nausea, vomiting, bloating, weight gain, headaches, food cravings, and mood changes.
    • Pulmonary Edema
      • Pulmonary edema (swelling or fluid in the lungs) can either be caused by cardiogenic causes (congestive heart failure, heart attacks, abnormal heart valves) or noncardiogenic causes such as ARDS, kidney failure, high altitude, pneumothorax, pleural effusion, aspirin overdose, pulmonary embolism, and infections. The treatment of pulmonary edema depends on the cause of the condition.
    • Infertility
      • Infertility is the diminished ability to conceive a child. The primary cause of infertility in men is a sperm disorder. In women, the primary cause of infertility is an ovulation disorder. Most forms of infertility can be treated. Conventional infertility therapies include drugs or surgery.
    • Graves' Disease
      • Graves' disease is an autoimmune disease that affects the thyroid. Some of the symptoms of Graves' disease include hand tremors, rapid heartbeat, trouble sleeping, enlarged thyroid, thinning of the skin or fine brittle hair. Causes of Graves' disease are thought to be multifactorial such as genes, gender, stress, and infection. Treatment for Graves' disease is generally medication.
    • Pregnancy: Trying to Conceive
      • Trying to get conceive, or become pregnant can be challenging, frustrating, and an emotional rollercoaster for some couples. There are things you can do to chart progress, which may ultimately lead to a successful healthy pregnancy, or, when necessary, lead to discussions with a fertility specialist. Being aware of your menstrual cycle, charting your fertility pattern, knowing the reasons for infertility, and treating infertility are key points to discuss with your partner and physician.
    • Gestational Diabetes
      • Gestational diabetes is a condition that is first recognized during pregnancy and is characterized by high blood sugar. Approximately 4% of all pregnancies are diagnosed with gestational diabetes. Low blood sugar is prevented by hormones produced by the placenta during a woman's pregnancy. The actions of insulin are stopped by these hormones. Gestational diabetes is the result of the pancreas' s inability to produce enough insulin to overcome the effect of the increase hormones during pregnancy.
    • Women's Health
      • Women's health is an important topic area to guide a woman through the stages of her life, as well as knowing the conditions and diseases that may occur. Educating yourself so that the transitions into different phases of life is key to a healthy, happy, and productive life.
    • Pregnancy Basics
      • Pregnancy can bring challenges like weight gain, stretch marks, varicose veins, heartburn, constipation, hemorrhoids, problems sleeping, and wondering if it is safe to have sex while pregnant. Learn how to manage and move through these challenges during pregnancy.
    • Sexually Transmitted Diseases and Pregnancy (STDs)
      • When you are pregnant, many sexually transmitted diseases (STDs) can be especially harmful to you and your baby. These STDs include herpes, HIV/AIDS, genital warts (HPV), hepatitis B, chlamydia, syphilis, gonorrhea, and trichomoniasis. Symptoms include bumps, sores, warts, swelling, itching, or redness in the genital region. Treatment of STDs while pregnant depends on how far along you are in the pregnancy and the progression of the infection.
    • Pregnancy: Pain Relief Options for Childbirth
      • Women experience and tolerate pain differently. For some pregnant women, focused breathing is all they need to get through labor and childbirth; but for others, numbing of the pain is desired. There are a number of different medications a woman can take during labor and childbirth. It is important for you to learn what pain relief options are available. Please discuss the options with your health care provider well before your "birth day" so that when you are in labor you understand the choices.
    • Smokeless Tobacco
      • Smokeless tobacco can have negative health effects such as cancers, poor oral health (gum disease and tooth decay), infertility, pregnancy complications, and nicotine addiction.
    • Breast Cancer During Pregnancy
      • Breast cancer occurs in about 1 in every 1,000 pregnant women. Treatment of breast cancer during pregnancy involves surgery, but it is very difficult to protect the baby from the dangerous effects of radiation and chemotherapy. It can be an agonizing to decide whether or not to undergo breast cancer treatment while one is pregnant.
    • Reproductive Health
      • Reproductive health encompasses the beginning of menstruation for women, choosing the right birth control method for you and your partner, preventing contracting sexually transmitted diseases (STDs), and for women, ending with the menopausal transition.

Pregnancy: Preeclampsia and Eclampsia

What is pulmonary edema?

Edema, in general, means swelling. This typically occurs when fluid from inside blood vessels seeps outside the blood vessel into the surrounding tissues, causing swelling. This can happen either because of too much pressure in the blood vessels or not enough proteins in the bloodstream to hold on to the fluid in the plasma (the part of the blood that does not contain any blood cells).

Pulmonary edema is the term used when edema happens in the lungs. The immediate area outside of the small blood vessels in the lungs is occupied by very tiny air sacs called the alveoli. This is where oxygen from the air is picked up by the blood passing by, and carbon dioxide in the blood is passed into the alveoli to be exhaled out. Alveoli normally have a thin wall that allows for this air exchange, and fluids are usually kept out of the alveoli unless these walls lose their integrity.
