Nausea and vomiting of pregnancy is a common condition during early pregnancy. It is often called morning sickness as the symptoms are usually worse in the morning but can occur at any time of the day, and sometimes continue throughout the day. Nausea and vomiting typically commence around weeks 8 or 9 of pregnancy and subside after 12—14 weeks.

Managing nausea and vomiting in pregnancy in a primary care setting
This common condition of pregnancy has potential for costly medical management and significant psychosocial and medical morbidity. Practice Bulletin No. September American College of Obstet Gynecol ;e Furthermore, some women do not seek treatment because of concerns about safety of medications 3.
Once nausea and vomiting of pregnancy progresses, it can become more difficult to control symptoms; treatment in the early stages may prevent more serious complications, including hospitalization 4.
Mild cases of nausea and vomiting of pregnancy may be resolved with lifestyle and dietary changes, and safe and effective treatments are available for more severe cases. The purpose of this document is to review the best available evidence about the diagnosis and management of nausea and vomiting of pregnancy.
A common condition of pregnancy with potential for costly medical management and significant psychosocial and medical morbidity. Nausea and vomiting is an expectation for the majority of women during the first trimester of pregnancy. Among affected woman, subsequent pregnancies have a recurrence of Conditions with increased placental mass such as molar pregnancy and multiple gestations are associated with a higher risk for nausea and vomiting. The severity of symptoms is variable from patient to patient and they typically peak by 9 weeks.
With early treatment and dietary counseling, the severity of symptoms diminishes as gestation advances; for most women, symptoms abate or resolve by the end of the first trimester. However, for some women, the condition is severe and progresses to hyperemesis gravidarum, which occurs in 0.
Hyperemesis is the most common reason for obstetrical triage visits and hospital admission in the first half of pregnancy and significantly impacts psychosocial well-being, loss of productivity, and quality of life. Symptoms of fever or abdominal pain should also prompt an investigation for other causes in the differential because neither are typical features of hyperemesis.
Abnormal laboratory findings in hyperemesis can include mildly elevated liver transaminase and bilirubin, elevated amylase, and suppressed thyroid stimulating hormone TSH levels.
While death due to hyperemesis is rare, morbidity can be significant if the condition is not properly managed, not to mention the psychological impact that prompts some women to consider termination of pregnancy. Wernicke encephalopathy is caused by vitamin B1 deficiency as a result of persistent vomiting leading to nutrition deprivation and has resulted in permanent neurological disability and death.
As such, it is important that treatment, particularly on admission, include hydration and replacement of the B vitamin, thiamine and attention to electrolyte balance. A systematic review and meta-analysis of women with hyperemesis gravidarum showed a higher incidence of low birthweight and small for gestational age infants at birth, and premature infants.
Treatment of nausea and vomiting depends on the perception of severity. Basic recommendations include avoidance of stimuli that provoke nausea and vomiting such as sensory stimuli to strong odors, and other sensory stimuli such as heat and noises that trigger the labyrinthine areas. Dietary counseling about frequent small meals and avoidance of spicy or fatty foods is appropriate even though the evidence for such recommendation is lacking.
Ginger has been recommended and shown, in some randomized trials, to improve symptoms for some women. A systematic review of randomized trials found no difference for P6 acupuncture and acupressure wristbands compared to placebo. For many decades pyridoxine vitamin B6 has been the primary recommendation for pharmacotherapy for nausea and vomiting of pregnancy. Doxylamine 10 mg and vitamin B6 10 mg was available for use in the United States from to as Bendectin until removed from the market.
Many clinicians continued to prescribe vitamin B6 and doxylamine as first line as an over-the-counter regimen for nausea and vomiting. In the US Food and Drug Administration has approved the release of a new product containing doxylamine-vitamin B6, marketed as Diclectin, which was proven effective in significantly improving nausea and vomiting symptoms compared to placebo.
Various phenothiazines have been prescribed and are effective as treatment for more significant nausea and vomiting. Over the last decade drugs that reduce chemotherapy-induced emesis the 5-hydroxytryptamine 3 inhibitor, ondansetron, and metoclopramide have gained favor as a treatment for women with hyperemesis. In various trials both have been found to have similar efficacy when given orally, subcutaneously and intravenously IV.
For hyperemesis resistant to traditional antiemetic regimens, corticosteroids have been studied in randomized trials to reduce readmission with IV dosing followed by oral tapering. Treatment with methylprednisolone should be reserved for refractory cases of hyperemesis as a last-resort treatment. Prolonged and persistent nausea and vomiting can lead to dehydration, ketosis, and electrolyte imbalance.
As such, judicious IV hydration, including electrolytes, dextrose and thiamine-containing vitamins, should be administered to women who cannot tolerate oral liquids or feeding.
Enteral or parenteral nutrition is occasionally required for women with persistent hyperemesis who are not responsive to medical management and unable to stabilize their weight.
If necessary, total parenteral nutrition through a peripherally inserted central catheter PICC can be used as a last resort. However, PICC parenteral nutrition is not without the potential for maternal infectious morbidities. Nausea and vomiting of pregnancy is common, impacts quality of life, and is costly. Hyperemesis is a serious form of the conditions and has the potential for serious morbidity if not managed appropriately.
Prenatal vitamins in the preconception period may reduce the severity of nausea and vomiting in early pregnancy. Early treatment with vitamin B6 and B6 plus doxylamine as a first-line therapy is safe and effective. Hyperemesis or refractory cases lead to dehydration, vitamin deficiency, and weight loss, therefore, attention to hydration, vitamin replacement, nutrition, and antiemetic therapy is critical to avoid maternal morbidity.

The exact cause is unknown. In most cases, it is a mild, self-limited condition that can be controlled with conservative measures and has no adverse fetal sequelae. Patients with nausea and vomiting of pregnancy should be evaluated for other causes, particularly if symptoms are unremitting or presentation is atypical. Initial treatment is conservative and includes dietary changes, emotional support, and vitamin B 6 supplementation. Several safe and effective pharmacologic therapies are available for women who do not improve with initial treatment. Women with hyperemesis gravidarum may require more aggressive interventions, including hospitalization, rehydration therapy, and parenteral nutrition.

Because morning sickness is common in early pregnancy, the presence of nausea and vomiting of pregnancy may be minimized by obstetricians, other obstetric care providers, and pregnant women and, thus, undertreated 1.

Сьюзан вздохнула, мысли ее вернулись к Цифровой крепости. Она не могла поверить, что такой алгоритм может быть создан, но ведь доказательство налицо - у нее перед глазами. ТРАНСТЕКСТ не может с ним справиться. Сьюзан подумала о Стратморе, о том, как мужественно он переносит тяжесть этого испытания, делая все необходимое, сохраняя спокойствие во время крушения. Иногда она видела в нем что-то от Дэвида.
Сьюзан вдруг поняла, что стала смеяться гораздо чаще, чем раньше. Казалось, не было на свете ничего, что Дэвид не мог бы обратить в шутку. Это было радостное избавление от вечного напряжения, связанного с ее служебным положением в АНБ. В один из прохладных осенних дней они сидели на стадионе, наблюдая за тем, как футбольная команда Рутгерса громит команду Джорджтауне кого университета. - Я забыла: как называется вид спорта, которым ты увлекаешься? - спросила Сьюзан.
Стратмор сжимал ее все сильнее.
Сирены продолжали завывать; то и дело вспыхивали сигнальные огни. Тремя этажами ниже дрожали и гудели резервные генераторы. Сьюзан знала, что где-то на дне этого погруженного в туман подземелья есть рубильник. Кроме того, она понимала, что времени почти не оставалось. Стратмор сидел наверху с береттой в руке.
Я его выгнал.
