Haemorrhoids (piles) are swollen veins at or inside the anal area, resulting from impaired venous return, straining associated with constipation, or increased intra-abdominal pressure in later pregnancy. They are more common in pregnant than non-pregnant women. It is reported by 16% of women at 6 months postpartum. Most pregnant women in countries where the diet is not heavily fiber-based may develop hemorrhoids, although they will usually be asymptomatic. Hemorrhoids can cause bleeding, itching, soiling or pain, and they can become strangulated. Symptoms may resolve spontaneously after pregnancy, although hemorrhoids are also common in the days after childbirth. Conservative treatments for hemorrhoids in pregnancy include dietary modification, local treatments, bowel stimulants or depressants, or phlebotonics (to strengthen capillaries and improve microcirculation). Treatment with oral hydroxyethylrutosides may help improve first and second degree hemorrhoids, but more information on safety in pregnancy is needed. Other treatments and approaches have not been evaluated in pregnant women.

Physicians, Nurse Practitioners, Physician Assistants, Nurses and Midwives will typically ask for the need of relief. Women in labor have many pain relief options that work well and pose small risks when given by a trained and experienced clinician. Clinicians also can use different methods for pain relief at different stages of labor. Still, not all options are available at every hospital and birthing center. Depending on the health history of the mother, the presence of allergies or other concerns, some choices will work better than others.

There are many methods of relieving pain used for labor. Rare and unpredictable, serious complications sometimes occur. Also, most medicines used to manage pain during labor pass freely into the placenta to the baby. Asking questions about the procedures and medications might affect the baby are valid questions.

Pica is a craving for nonedible items such as dirt or clay. It is caused by iron deficiency which is normal during pregnancy and can be overcome with iron in prenatal vitamins or, if severe, parenteral iron

An epidural is a procedure that involves placing a tube (catheter) into the lower back, into a small space below the spinal cord. Small doses of medicine can be given through the tube as needed throughout labor. With a spinal block, a small dose of medicine is given as a shot into the spinal fluid in the lower back. Spinal blocks usually are given only once during labor. Epidural and spinal blocks allow most women to be awake and alert with very little pain during labor and childbirth. With an epidural, pain relief starts 10 to 20 minutes after the medicine has been given. The degree of numbness felt can be adjusted. With spinal block, good pain relief starts right away, but it only lasts 1 to 2 hours.

Although movement is possible, walking may not be if the medication affects motor function. An epidural can lower your blood pressure, which can slow your baby's heartbeat. Fluids given through IV are given to lower this risk. Fluids can cause shivering. But women in labor often shiver with or without an epidural. If the covering of the spinal chord is punctured by the catheter, a bad headache may develop. Treatment can help the headache. An epidural can cause a backache that can occur for a few days after labor. An epidural can prolong the first and second stages of labor. If given late in labor or if too much medicine is used, it might be hard to push when the time comes. An epidural increases risk of assisted vaginal delivery.

Although the definition is imprecise, it occurs in approximately 0.3-1% of vaginal births.

For most women, PGP resolves in weeks after delivery but for some it can last for years resulting in a reduced tolerance for weight bearing activities. PGP can take from 11 weeks, 6 months or even up to 2 years postpartum to subside. However, some research supports that the average time to complete recovery is 6.25 years, and the more severe the case is, the longer recovery period.

Overall, about 45% of all pregnant women and 25% of all women postpartum suffer from PGP. During pregnancy, serious pain occurs in about 25%, and severe disability in about 8% of patients. After pregnancy, problems are serious in about 7%. There is no correlation between age, culture, nationality and numbers of pregnancies that determine a higher incidence of PGP.

If a woman experiences PGP during one pregnancy, she is more likely to experience it in subsequent pregnancies; but the severity cannot be determined.

The most common cause is the mismanagement of 3rd stage of labor, such as:

- Fundal pressure

- Excess cord traction during the 3rd stage of labor

Other natural causes can be:

- Uterine weakness, congenital or not

- Precipitate delivery

- Short umbilical cord

It is more common in multiple gestation than in singleton pregnancies.

The incidence is of 1/2000 pregnancies.

Factors increasing the risk (to either the woman, the fetus/es, or both) of pregnancy complications beyond the normal level of risk may be present in a woman's medical profile either before she becomes pregnant or during the pregnancy. These pre-existing factors may relate to physical and/or mental health, and/or to social issues, or a combination.

Some common risk factors include:

- Age of either parent

- Adolescent parents

- Older parents

- Exposure to environmental toxins in pregnancy

- Exposure to recreational drugs in pregnancy:

- Ethanol during pregnancy can cause fetal alcohol syndrome and fetal alcohol spectrum disorder.

- Tobacco smoking and pregnancy, when combined, causes twice the risk of premature rupture of membranes, placental abruption and placenta previa. Also, it causes 30% higher odds of the baby being born prematurely.

- Prenatal cocaine exposure is associated with, for example, premature birth, birth defects 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 when compared to control infants. Also, prenatal methamphetamine use is believed to have long-term effects in terms of brain development, which may last for many years.

- Cannabis in pregnancy is possibly associated with adverse effects on the child later in life.

- Exposure to Pharmaceutical drugs in pregnancy. Anti-depressants, for example, may increase risks of such outcomes as preterm delivery.

- Ionizing radiation

- Risks arising from previous pregnancies:

- Complications experienced during a previous pregnancy are more likely to recur.

- Many previous pregnancies. Women who have had five previous pregnancies face increased risks of very rapid labor and excessive bleeding after delivery.

- Multiple previous fetuses. Women who have had more than one fetus in a previous pregnancy face increased risk of mislocated placenta.

- Multiple pregnancy, that is, having more than one fetus in a single pregnancy.

- Social and socioeconomic factors. Generally speaking, unmarried women 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 delays prenatal care. They preclude other preventive care, may disrupt life plans and on average have worse health and psychological outcomes for the mother and, if birth occurs, the child.

- Height. Pregnancy in women whose height is less than 1.5 meters (5 feet) correlates with higher incidences of preterm birth and underweight babies. Also, these women are more likely to have a small pelvis, which can result in such complications during childbirth as shoulder dystocia.

- Weight

- Low weight: Women whose pre-pregnancy weight is less than 45.5 kilograms (100 pounds) are more likely to have underweight babies.

- Obese women are more likely to have very large babies, potentially increasing difficulties in childbirth. Obesity also increases the chances of developing gestational diabetes, high blood pressure, preeclampsia, experiencing postterm pregnancy and/or requiring a cesarean delivery.

- Intercurrent disease in pregnancy, that is, a disease and condition not necessarily directly caused by the pregnancy, such as diabetes mellitus in pregnancy, SLE in pregnancy or thyroid disease in pregnancy.

One reason that poverty produces such high rates of fistula cases is the malnutrition that exists in such areas. Lack of money and access to proper nutrition, as well as vulnerability to diseases that exist in impoverished areas because of limited basic health care and disease prevention methods, cause inhabitants of these regions to experience stunted growth. Sub-Saharan Africa is one such environment where the shortest women have on average lighter babies and more difficulties during birth when compared with full-grown women. This stunted growth causes expectant mothers to have skeletons unequipped for proper birth, such as an underdeveloped pelvis. This weak and underdeveloped bone structure increases the chances that the baby will get stuck in the pelvis during birth, cutting off circulation and leading to tissue necrosis. Because of the correlation between malnutrition, stunted growth, and birthing difficulties, maternal height can at times be used as a measure for expected labor difficulties.

High levels of poverty also lead to low levels of education among impoverished women concerning maternal health. This lack of information in combination with obstacles preventing rural women to easily travel to and from hospitals lead many to arrive at the birthing process without prenatal care. This can cause a development of unplanned complications that may arise during home births, in which traditional techniques are used. These techniques often fail in the event of unplanned emergencies, leading women to go to hospital for care too late, desperately ill, and therefore vulnerable to the risks of anesthesia and surgery that must be used on them. In a study of women who had prenatal care and those who had unbooked emergency births, “the death rate in the booked-healthy group was as good as that in many developed countries, [but] the death rate in the unbooked emergencies was the same as the death rate in England in the 16th and 17th centuries.” In this study, 62 unbooked emergency women were diagnosed with obstetric fistulae out of 7,707 studied, in comparison to three diagnosed booked mothers out of 15,020 studied. In addition, studies find that education is associated with lower desired family size, greater use of contraceptives, and increased use of professional medical services. Educated families are also more likely to be able to afford health care, especially maternal healthcare.

Uterine inversion is often associated with significant Post-partum hemorrhage. Traditionally it was thought that it presented with haemodynamic shock "out of proportion" with blood loss, however blood loss has often been underestimated. The parasympathetic effect of traction on the uterine ligaments may cause bradycardia.

PGP in pregnancy seriously interferes with participation in society and activities of daily life; the average sick leave due to posterior pelvic pain during pregnancy is 7 to 12 weeks.

In some cases women with PGP may also experience emotional problems such as anxiety over the cause of pain, resentment, anger, lack of self-esteem, frustration and depression; she is three times more likely to suffer postpartum depressive symptoms. Other psychosocial risk factors associated with woman experiencing PGP include higher level of stress, low job satisfaction and poorer relationship with spouse.

The major concern of shoulder dystocia is damage to the upper brachial plexus nerves. These supply the sensory and motor components of the shoulder, arm and hands. The ventral roots (motor pathway) are most prone to injury. The cause of injury to the baby is debated, but a probable mechanism is manual stretching of the nerves, which in itself can cause injury. Excess tension may physically tear the nerve roots out from the neonatal spinal column, resulting in total dysfunction.

- Klumpke paralysis

- Erb's Palsy

- Fetal hypoxia

- Fetal death

- Cerebral palsy

- Maternal post partum hemorrhage (11%)

- Vaginal lacerations and 3rd/4th degree tears, extended episiotomies

- uterine rupture

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 specialising in maternal-fetal medicine.

Serious pre-existing disorders which can reduce a woman's physical ability to survive pregnancy include a range of congenital defects (that is, conditions with which the woman herself was born, for example, those of the heart or , some of which are listed above) and diseases acquired at any time during the woman's life.

Emergency exploratory laparotomy with cesarean delivery accompanied by fluid and blood transfusion are indicated for the management of uterine rupture. Depending on the nature of the rupture and the condition of the patient, the uterus may be either repaired or removed (cesarean hysterectomy). Delay in management places both mother and child at significant risk.

Usually, acute pain is generated from an obvious cause and is expected to last for only a few days or weeks. It is usually managed with medication and non-pharmacological treatment to provide comfort. Acute pain is an indication for needed assessment, treatment and prevention. While a child is experiencing pain, physiological changes occur that can further jeopardize healing and recovery. Unrelieved pain can cause alkalosis and hypoxemia that result from rapid, shallow breathing. This shallow breathing then leads to the accumulation of fluid in the lungs, taking away to the ability to cough. Dangerously enough, this can prevent the secretions from being expelled. Pain can cause an increase in blood pressure and heart rate, creating great stress on the heart. Additionally, pain increases the release of anti-inflammatory steroids that reduce the ability to fight infection. These same steroids that are released increase the metabolic rate and impact healing. Another harmful outcome of acute pain is an increase in sympathetic effects such as the inability to urinate. Such aches can even slow down the gastrointestinal system.

Inadequate pain management in children can lead to psycho-social consequences. Disinterest in food, apathy, sleep problems, anxiety, avoidance of discussions about health, fear, hopelessness and powerlessness are just some of the many. Other consequences can be extended hospital stays, high readmission rates and a longer recovery. On the other hand, the American Association of Pediatrics describes pain with immunizations as "The pain associated with the majority of immunizations is minor.".

Examples of harmful consequences due to unrelieved pain:

- infants with a higher than average heel sticks can have poor cognitive and motor function

- distress caused by needle-sticks make medical treatments later on more difficult

- children who have experienced invasive procedures often times develop post-traumatic stress (PST)

- boys circumcised without anesthesia were found to have greater distress than uncircumcised boys.

- severe pain as a child is associated with higher reports of pain in adults

Acute pain can be expected in response to many if not most invasive procedures. Anticipation of pain and distress can guide a pre-treatment, pain-prevention plan based on past reports of pain associated with the medical procedure. Individuals with technical expertise and experience are more likely to minimize the pain as much as possible. Preparation before a procedure with information that is understood by children and parents decrease distress. Parents can contribute to the improvement of this issue by learning effective methods/ways to comfort their child. Types of procedures determine the use of deep sedation or anesthesia. In some cases, the best method to prevent and relieve pain is by building self-esteem. Suggested cognitive behavioral strategies are: imagery, relaxation, a massage, heat compression, calm adults, a quiet environment, and confident explanations by providers. Since distress can be addressed and controlled, some children benefit from the opportunity for self-regulation. Pain reduction during invasive procedures is closely linked to controlling distress. Treating distress even for minor or uncomplicated procedures, likes venipuncture can be implemented.

Neuropathic pain is associated with nerve injuries or abnormal sensitivities to touch or contact. Other causes are, postsurgical, post-amputation.

In 2013 it resulted in 19,000 maternal deaths down from 29,000 deaths in 1990.

If cesarean section is obtained in a timely manner, prognosis is good. Prolonged obstructed labour can lead to stillbirth, obstetric fistula, and maternal death.

A 2008 study found that over 85% of women having a vaginal birth sustain some form of perineal trauma, and 60-70% receive stitches. A retrospective study of 8,603 vaginal deliveries in 1994 found a third degree tear had been clinically diagnosed in only 50 women (0.6%). However, when the same authors used anal endosonography in a consecutive group of 202 deliveries, there was evidence of third degree tears in 35% of first-time mothers and 44% of mothers with previous children. These numbers are confirmed by other researchers in 1999.

A study by the Agency for Healthcare Research and Quality (AHRQ) found that in 2011, first- and second-degree perineal tear was the most common complicating condition for vaginal deliveries in the U.S. among women covered by either private insurance or Medicaid.

Second-degree perineal laceration rates were higher for women covered by private insurance than for women covered by Medicaid.

Risk factors for developing a cystocele are:

- an occupation involving or history of heavy lifting

- pregnancy and childbirth

- chronic lung disease/smoking

- family history of cystocele

- exercising incorrectly

- ethnicity (risk is greater for Hispanic and whites)

- hypoestrogenism

- pelvic floor trauma

- connective tissue disorders

- spina bifida

- hysterectomy

- cancer treatment of pelvic organs* childbirth; correlates to the number of births

- forceps delivery

- age

- chronically high intra-abdominal pressures

- chronic obstructive pulmonary disease

- constipation

- obesity

Connective tissue disorders predispose women to developing cystocele and other pelvic organ prolapse. The tensile strength of the vaginal wall decreases when the structure of the collagen fibers change and become weaker.

A uterine scar from a previous cesarean section is the most common risk factor. (In one review, 52% had previous cesarean scars.) Other forms of uterine surgery that result in full-thickness incisions (such as a myomectomy), dysfunctional labor, labor augmentation by oxytocin or prostaglandins, and high parity may also set the stage for uterine rupture. In 2006, an extremely rare case of uterine rupture in a first pregnancy with no risk factors was reported.

In the US, greater than than 200,000 surgeries are performed each year for pelvic organ prolapse and 81% of these are to correct cystocele. Cystocele occurs most frequently compared to the prolapse of other pelvic organs and structure. Cystocele is found to be three times as common as vaginal vault prolapse and twice as often as posterior vaginal wall defects. The incidence of cystocele is around 9 per 100 women-years. The highest incidence of symptoms occurs between ages of 70-79 years old. Based on population growth statistics, the number of women with prolapse will increase by a minimum of 46% by the year 2050 in the US. Surgery to correct prolapse after hysterectomy is 3.6 per 1,000 women-years.

During labor the shoulder will be wedged into the pelvis and the head lie in one iliac fossa, the breech in the other. With further uterine contractions the baby suffocates. The uterus continues to try to expel the impacted fetus and as its retraction ring rises, the musculature in the lower segments thins out leading eventually to a uterine rupture and the death of the mother. Impacted shoulder presentations contribute to maternal mortality. Obviously a cesarean section should be performed before the baby has died, but even when the baby has died or impaction has occurred, C/S is the method of choice of delivery, as alternative methods of delivery are potentially too traumatic for the mother. If the baby is preterm or macerated and very small a spontaneous delivery has been observed.

Causes of postpartum hemorrhage are uterine atony, trauma, retained placenta, and coagulopathy, commonly referred to as the "four Ts":

- Tone: uterine atony is the inability of the uterus to contract and may lead to continuous bleeding. Retained placental tissue and infection may contribute to uterine atony. Uterine atony is the most common cause of postpartum hemorrhage.

- Trauma: Injury to the birth canal which includes the uterus, cervix, vagina and the perineum which can happen even if the delivery is monitored properly. The bleeding is substantial as all these organs become more vascular during pregnancy.

- Tissue: retention of tissue from the placenta or fetus may lead to bleeding.

- Thrombin: a bleeding disorder occurs when there is a failure of clotting, such as with diseases known as coagulopathies.
