Hyperemesis gravidarum is a severe form of toxicosis characterized by significant nausea and vomiting that makes adequate nutrition and hydration difficult or impossible. This condition usually occurs in the first trimester of pregnancy and can persist until delivery. Hyperemesis gravidarum differs from normal morning sickness in its intensity and duration, and sometimes leads to significant weight loss, electrolyte imbalances, and other systemic complications. These manifestations can negatively affect not only the health of the pregnant woman, but also the development of the fetus, which makes timely diagnosis and treatment especially important.
History of the disease and interesting historical facts
Hyperemesis gravidarum has been known for centuries. In ancient times, it was described as a “curse” associated with pregnancy and was thought to be the result of an evil eye. In the Middle Ages, according to some sources, women suffering from the disorder could be accused of witchcraft. In more modern times, hyperemesis gravidarum began to be closely analyzed in the early 20th century, and its mechanisms were first studied. In the 1940s, extensive research was conducted that showed a link between hyperemesis and vitamin deficiency, which influenced changes in clinical practice in the treatment of this condition.
Epidemiology
According to modern research, hyperemesis gravidarum occurs in 0.3-3% of all pregnancies. The frequency of its occurrence varies depending on the population and a number of other factors. In some ethnic groups, this syndrome is more common, which may be due to genetic, environmental and social factors. A high risk is observed in women who have already had cases of hyperemesis in their anamnesis, as well as in women with multiple pregnancies. Scientists have found that patients with hyperemesis have increased rates of hospitalization in the first months of pregnancy, which emphasizes the importance of early diagnosis and treatment.
Genetic predisposition to this disease
Current genetic research suggests a possible predisposition to hyperemesis gravidarum. In particular, neurotropic genes responsible for the regulation of vomiting and nausea, such as the serotonin (5-HT3) gene, may play a key role in the pathogenesis of the condition. Some studies suggest that mutations in these genes may lead to a strong reactivity to pregnancy hormones such as hCG and estradiol, which contributes to the development of hyperemesis gravidarum. However, more research is needed to better understand the genetic factors associated with this condition.
Risk factors for the development of this disease
Risk factors for hyperemesis gravidarum can be divided into several categories:
- Physical factors: previous experience of hyperemesis, multiple pregnancy, history of migraine.
- Chemical factors: the influence of pregnancy hormones, especially hCG and estrogens.
- Psychological factors: presence of stress or previous anxiety disorders.
- Other factors: the woman’s age (more common in young women), the presence of certain genetic predispositions.
A good understanding of these risk factors allows physicians to more effectively diagnose and manage patients' conditions.
Diagnosis of this disease
Diagnosis of hyperemesis gravidarum includes several stages:
- Main symptoms: persistent vomiting, severe nausea, loss of appetite, weight loss of more than 5% from the initial weight, electrolyte disturbances.
- Laboratory tests: blood tests to determine electrolyte levels, glucose and kidney function.
- Radiological examinations: If necessary, ultrasound examination may be used to assess the condition of the fetus and exclude other complications.
- Other types of disease diagnostics: keeping a food diary, assessing the quality of life.
- Differential diagnosis: It is important to exclude conditions such as gastritis, pancreatitis and other infections.
This comprehensive approach allows for the identification of hyperemesis at an early stage and the initiation of appropriate treatment.
Treatment
Treatment for hyperemesis gravidarum usually involves several components:
- General treatment: correction of water-electrolyte balance using infusion therapy.
- Pharmacological treatment: use of antiemetics such as metoclopramide, ondansetron, etc., to reduce vomiting.
- Surgical treatment: In rare cases, placement of a feeding tube or gastrostomy may be required.
- Other treatments: Alternative methods such as acupuncture and the use of ginger.
Treatment should be individually tailored based on the severity of the condition and response to therapy.
List of medications used to treat this disease
Some of the commonly used medications to treat hyperemesis gravidarum include:
- metoclopramide
- Ondansetron
- Dexamethasone
- Pyridoxine (vitamin B6)
- Ginger (as supplements or tea)
It is also worth noting that drug treatment should be carried out under the strict supervision of a physician.
Disease monitoring
Monitoring the condition of a pregnant woman with hyperemesis is a key aspect to prevent complications. It usually includes:
- Monitoring body weight and water-electrolyte balance.
- Regular laboratory tests to assess liver and kidney function.
- Assessment of the condition of the fetus using ultrasound.
- Prognosis: With timely treatment, most women recover without serious consequences.
- Complications: May occur in advanced cases, including dehydration and electrolyte imbalance.
Proper monitoring can reduce the risk of complications.
Age-related features of the disease
Hyperemesis gravidarum can manifest itself in different ways depending on age:
- Young women (under 25 years of age) are more likely to experience more severe forms of hyperemesis.
- Middle-aged women (25-35 years) may have more persistent symptoms that are easier to treat.
- Older women (over 35 years) may be at risk for developing underlying medical conditions, which can complicate diagnosis and treatment.
This requires an individual approach and a combination of treatment methods.

Advice from Dr. Oleg Korzhikov
If symptoms of hyperemesis occur, it is important not to delay a visit to the doctor and strictly follow his instructions. Questions that patients often have:
— Nutrition: “What should I eat if everything makes me vomit?” Answer: Try to eat small portions, avoiding fatty and heavy foods.
— Hydration: “How should I drink if I am constantly vomiting?” The answer is to drink sips, use special solutions for rehydration.
— Medicines: “Can I take medicines without a doctor’s prescription?” The answer is no way, it can make the condition worse.
