HIGH RISK PREGNANCY
Complications of pregnancy
Complications of pregnancy are health problems that are related to pregnancy. Complications that occur primarily during childbirth are termed obstetric labor complications, and problems that occur primarily after childbirth are termed puerperal disorders. Severe pregnancy complications, childbirth, and puerperium are present in 1.6% of mothers in the US and 1.5% of mothers in Canada. In the immediate postpartum period (puerperium), 87% to 94% of women report at least one health problem. Long-term health problems (persisting after six months postpartum) are reported by 31% of women.
In 2016, complications of pregnancy, childbirth, and the puerperium resulted globally in 230,600 deaths, down from 377,000 deaths in 1990. The most common causes of maternal mortality are maternal bleeding, postpartum infections including maternal sepsis, hypertensive diseases of pregnancy, obstructed labor, and pregnancy with the abortive outcome, including miscarriage, ectopic pregnancy, and elective abortion.
There is no clear distinction between complications of pregnancy and symptoms and discomforts of pregnancy. However, the latter does not significantly interfere with activities of daily living or pose any significant threat to the health of the mother or baby. Still, in some cases, the same basic feature can manifest as either a discomfort or a complication depending on the severity. For example, mild nausea may merely be a discomfort (morning sickness), but if severe and with vomiting causing water-electrolyte imbalance, it can be classified as a pregnancy complication (hyperemesis gravidarum

Maternal problems
The following problems originate mainly in the mother.
Gestational diabetes
Gestational diabetes is when a woman without diabetes develops high blood sugar levels during pregnancy.
Hyperemesis gravidarum
Hyperemesis gravidarum is the presence of severe and persistent vomiting, causing dehydration and weight loss. It is more severe than the more common morning sickness and affects 0.5–2.0% of pregnant women.
Pelvic girdle pain
- Caused by: Pelvic girdle pain (PGP) disorder is pain caused by instability and limitation of mobility and functioning in any three pelvic joints. PGP can begin peri or postpartum. PGP resolves in the weeks after delivery for most pregnant individuals, but for some, it can last for years, resulting in a reduced tolerance for weight-bearing activities. PGP affects around 45% of individuals during pregnancy: 25% report serious pain, and 8% are severely disabled.
- Treatment: The treatment modality is based on the severity. A mild case would require rest, rehabilitation therapy, and pain is usually manageable. More severe cases would also include mobility aids, strong analgesics, and sometimes surgery. One of the main factors in helping women cope is education, information, and support. Many treatment options are available.
High blood pressure
Potential severe hypertensive states of pregnancy are mainly:
- Preeclampsia – gestational hypertension, proteinuria (>300 mg), and edema. Severe preeclampsia involves a BP over 160/110 (with additional signs). It affects 5–8% of pregnancies.
- Eclampsia – seizures in a pre-eclamptic patient affect around 1.4% of pregnancies.
- Gestational hypertension
- HELLP syndrome – Hemolytic anemia, elevated liver enzymes, and a low platelet count. Incidence is reported as 0.5–0.9% of all pregnancies.
- Acute fatty liver of pregnancy is sometimes included in the preeclamptic spectrum. It occurs in approximately one in 7,000 to one in 15,000 pregnancies.
Venous thromboembolism
Deep vein thrombosis (DVT), a form of venous thromboembolism (VTE), has an incidence of 0.5 to 7 per 1,000 pregnancies and is the second most common cause of maternal death in developed countries after bleeding.
- Caused by: Pregnancy-induced hypercoagulability as a physiological response in preparation for the potential bleeding during childbirth.
Treatment: Prophylactic treatment, e.g., with low molecular weight heparin, may indicate additional risk factors for deep vein thrombosis.
Anemia
Levels of hemoglobin are lower in the third trimesters. The United Nations (UN) estimates that approximately half of pregnant individuals suffer from anemia worldwide. Anemia prevalences during pregnancy differed from 18% in developed countries to 75% in South Asia.
Treatment varies due to the severity of the anemia and can be used by increasing iron-containing foods, oral iron tablets, or using parenteral iron. infection.
A pregnant woman is more susceptible to certain infections. An increased immune tolerance in pregnancy causes this increased risk to prevent an immune reaction against the fetus and secondary to maternal physiological changes, including decreased respiratory volumes and urinary stasis due to an enlarging uterus. Pregnant individuals are more severely affected by, for example, influenza, hepatitis E, herpes simplex, and malaria. The evidence is more limited for coccidioidomycosis, measles, smallpox, and varicella. Mastitis or inflammation of the breast occurs in 20% of lactating individuals.
Some infections are vertically transmissible, meaning that they can affect the child as well.
Peripartum cardiomyopathy
Peripartum cardiomyopathy decreases heart function in the last month of pregnancy or up to six months post-pregnancy. It increases the risk of congestive heart failure, heart arrhythmias, thromboembolism, and cardiac arrest.
Hypothyroidism: Thyroid disease in women
Hypothyroidism (also called Hashimoto’s disease) is an autoimmune disease that affects the thyroid in pregnant individuals. This condition can have a profound effect during pregnancy and on the child. The infant may be seriously affected and have a variety of congenital disabilities. Many pregnant individuals with Hashimoto’s disease develop an underactive thyroid. The clinician will do an exam and order one or more tests.
Fetal and placental problems
The following problems occur in the fetus or placenta but may have serious consequences on the mother.
Ectopic pregnancy
Ectopic pregnancy is the implantation of the embryo outside the uterus
- Caused by: Unknown, but risk factors include smoking, advanced maternal age, and prior surgery or trauma to the fallopian tubes.
- Treatment: In most cases, keyhole surgery must be carried out to remove the fetus, along with the fallopian tube. If the pregnancy is very early, it may resolve independently, or it can be treated with methotrexate, an abortifacient.
Miscarriage
Miscarriage is the loss of a pregnancy before 20 weeks. In the UK, miscarriage is defined as the loss of a pregnancy during the first 23 weeks.
Placental abruption
Placental abruption is the separation of the placenta from the uterus.
- Caused by: Various causes, risk factors include maternal hypertension, trauma, and drug use.
- Treatment: Immediate delivery if the fetus is mature (36 weeks or older) or if a younger fetus or the mother is in distress. In less severe cases with immature fetuses, the situation may be monitored in the hospital, with treatment if necessary.
Placenta praevia
Placenta praevia is when the placenta fully or partially covers the cervix. placenta accreta
Placenta accreta is an abnormal adherence of the placenta to the uterine wall.
Multiple pregnancies
Multiples may become monochorionic, sharing the same chorion, with a resultant risk of twin-to-twin transfusion syndrome. Monochorionic multiples may become monoamniotic, sharing the same amniotic sac, resulting in umbilical cord compression and entanglement risk. In sporadic cases, there may be conjoined twins, possibly impairing the function of internal organs.
Vertically transmitted infection
The embryo and fetus have little or no immune function. They depend on the immune function of their mother. Several pathogens can cross the placenta and cause (perinatal) infection. Often microorganisms that produce minor illnesses in the mother are hazardous for the developing embryo or fetus. This can result in spontaneous abortion or major developmental disorders. For many infections, the baby is more at risk at particular stages of pregnancy. Problems related to perinatal infection are not always directly noticeable.
The term TORCH complex refers to a set of several different infections that may be caused by transplacental infection.
Babies can also become infected by their mothers during birth. During birth, babies are exposed to maternal blood and body fluids without the placental barrier intervening and the maternal genital tract. Because of this, blood-borne microorganisms (hepatitis B, HIV), organisms associated with sexually transmitted disease (e.g., gonorrhea and chlamydia), and normal fauna of the genito-urinary tract (e.g., Candida) are among those commonly seen in infection of newborns.
Intrauterine bleeding
There have been rare but known cases of intrauterine bleeding caused by the injury inflicted by the fetus with its fingernails or toenails.
General risk factors
Factors increasing the risk (to either the pregnant individual, the fetus/es, or both) of pregnancy complications beyond the normal level of risk may be present in the pregnant individual’s medical profile before becoming pregnant or during the pregnancy. These pre-existing factors may relate to the individual’s genetics, physical or mental health, environment, social issues, or a combination of those.
Biological
Some common biological risk factors include:
- Age of either parent
- Adolescent parents
- Adolescent mothers are at an increased risk of developing certain complications, including preterm birth and low infant birth weight.
- Older parents
- Adolescent parents
individuals are at an increased risk of complications during pregnancy and childbirth as they age. Complications for those 45 or older include increased risk of primary Caesarean delivery (i.e., C-section).
- Height: Pregnancy in individuals whose height is less than 1.5 meters (5 feet) correlates with higher incidences of preterm birth and underweight babies. Also, these individuals are more likely to have a small pelvis, resulting in such complications during childbirth as shoulder dystocia.
- Weight
- Low weight: individuals whose pre-pregnancy weight is less than 45.5 kilograms (100 pounds) are more likely to have underweight babies.
- Obese individuals are more likely to have huge babies, potentially increasing difficulties in childbirth. Obesity also increases the chances of developing gestational diabetes, high blood pressure, preeclampsia, experiencing post-term pregnancy, and requiring a cesarean delivery.
- Pre-existing disease in pregnancy or an acquired disease: A disease and condition not necessarily directly caused by the pregnancy, such as diabetes mellitus in pregnancy, lupus in pregnancy, or thyroid disease in pregnancy.
- Risks arising from previous pregnancies
- Complications experienced during a previous pregnancy are more likely to recur.
- Many previous pregnancies: individuals who have had five previous pregnancies face increased risks of very rapid labor and excessive bleeding after delivery.
- Multiple previous fetuses: individuals who have had more than one fetus in a previous pregnancy face an increased risk of the mislocated placenta.
- Multiple pregnancies: Having more than one fetus in a single pregnancy.
Environmental
810 women die every day from preventable causes related to pregnancy and childbirth; 94% occur in low and lower-middle-income countries.
Some common environmental risk factors include:
- Exposure to environmental toxins in pregnancy
- Exposure to recreational drugs in pregnancy
- Ethanol during pregnancy can cause fetal alcohol syndrome and a fetal alcohol spectrum disorder.
- Tobacco smoking and pregnancy, when combined, cause twice the risk of premature rupture of membranes, placental abruption, and placenta previa. Also, it causes a 30% higher odds of the baby being born prematurely.
- Prenatal cocaine exposure is associated with, for example, premature birth, congenital disabilities, and attention deficit disorder.
- Prenatal methamphetamine exposure can cause premature birth and congenital abnormalities. Other investigations have revealed short-term neonatal outcomes to include small deficits in infant neurobehavioral function and growth restriction compared to control infants. Also, prenatal methamphetamine use is believed to have long-term effects on brain development, which may last for many years. Cannabis in pregnancy is possibly associated with adverse effects on the child later in life.
- Ionizing radiation
- Social and socioeconomic factors: Generally speaking, unmarried individuals and those in lower socioeconomic groups experience an increased level of risk in pregnancy, due at least in part to lack of access to appropriate prenatal care.
- Unintended pregnancy: Unintended pregnancies preclude preconception care and delay prenatal care. They preclude other preventive care, disrupt life plans, and have worse health and psychological outcomes for the mother and, if birth occurs, the child.
- Exposure to pharmaceutical drugs in pregnancy: Anti-depressants, for example, may increase the risks of such outcomes as preterm delivery.
High-risk pregnancy
Some disorders and conditions can mean that pregnancy is considered high-risk (about 6-8% of pregnancies in the USA) and, in extreme cases, may be contraindicated. High-risk pregnancies are the main focus of doctors specializing in maternal-fetal medicine.
Serious pre-existing disorders which can reduce a woman’s physical ability to survive pregnancy include a range of congenital disabilities (that is, conditions with which the woman herself was born, for example, those of the heart or reproductive organs, some of which are listed above) and diseases acquired at any time during the woman’s life.

Water deficiency is more common during pregnancy than at other times. Most cases of water loss during pregnancy are mild, but severe water deficiency can be dangerous for both mother and child. The fetus places intense demands on the body and women who become pregnant need to consume extra nutrients.
Symptoms of water deficiency in pregnancy
Usually, the first sign of water deficiency is feeling thirsty. People who feel thirsty after sweating, spending long periods in the summer, or staying for long periods without water are particularly likely to become dehydrated. Other symptoms of water deficiency include:
-
Dry throat or mouth
-
Dry looking skin
-
Dark-colored urine
-
Constipation
Reasons for lack of water during pregnancy
1-Not drink enough water
Although nothing can be said about how much water people should drink, everyone’s needs are different. Pregnancy places additional demands on the body.
So women usually need to drink more water during pregnancy, who is physically active or who lives in a hot climate, She will sweat more and need more water. Individuals who abruptly change their activity level or move into warmer climates may require more water than they once had.
२-Not absorbing a sufficient amount of water
Certain medical conditions, especially those that cause vomiting and diarrhea, can make it difficult for the body to absorb the water it needs. Nausea and vomiting are more common during pregnancy than at other times. With hyperemesis gravidarum, which occurs in 3 percent of pregnancies, intense vomiting may be experienced, which causes weight loss and water loss.
Loss due to lack of water during pregnancy
A little water deficiency is not generally dangerous in pregnancy unless the woman quickly corrects the lack of water. Severe water deficiency can be dangerous for both mother and child. Lack of water can reduce amniotic fluid levels, which can affect the development of the baby and the production of breast milk. Lack of water can cause nutritional deficiencies, important for the pregnant woman’s health and the developing child.
How to reduce water loss during pregnancy?
To prevent water shortages, consider increasing fluid intake, carrying a water bottle, or taking frequent water breaks. Women who exercise in the hot summer or spend time outdoors should increase their fluids intake more. Some foods may make people more likely to experience water scarcity, including caffeine-rich foods or water. It is necessary to drink lots of water while consuming these foods.
