Hyperemesis gravidarum is rejection of the fetus

When a woman enters pregnancy, vomiting is a normal physiological reaction, because during this period, the hormones in the woman's body will undergo certain changes, thus affecting her daily eating habits, etc. Generally speaking, morning sickness will occur in the early stages of pregnancy. However, for some pregnant women, vomiting is more serious. This is not rejection of the fetus, it's just that your endocrine system is disordered.

More than half of women will experience early pregnancy reactions in the early stages of pregnancy, including dizziness, fatigue, drowsiness, loss of appetite, picky eating, aversion to greasy foods, nausea, vomiting, etc. The severity and duration of symptoms vary from person to person. Most symptoms appear around 6 weeks of pregnancy, reach a peak at 8 to 10 weeks, and disappear on their own around 12 weeks of pregnancy. A small number of pregnant women experience severe early pregnancy reactions, with frequent nausea and vomiting, and inability to eat, which can lead to fluid imbalance and metabolic disorders, and even endanger the life of the pregnant woman.

The causes of early pregnancy reactions may be related to increased human chorionic gonadotropin (HCG) in the body, gastrointestinal dysfunction, decreased gastric acid secretion and prolonged gastric emptying time. 0.3% to 1% of pregnant women will experience hyperemesis gravidarum, which is more common in young primiparas and is generally believed to be related to a significant increase in HCG.

Hyperemesis gravidarum occurs between early pregnancy and 16 weeks of gestation and is more common in young primigravidas. Generally, early pregnancy reactions appear about 40 days after menstruation has ceased and gradually worsen until frequent vomiting and inability to eat. The vomit contains bile or coffee-like substance. Severe vomiting can cause dehydration and electrolyte imbalance, and mobilize body fat, causing the intermediate product acetone to accumulate, causing metabolic acidosis. Patients experience significant weight loss, pale complexion, dry skin, weak pulse, decreased urine volume, and in severe cases, a drop in blood pressure, causing prerenal acute renal failure.

Patients with hyperemesis gravidarum should be hospitalized and fast for 2 to 3 days. The amount of water loss and electrolyte imbalance should be determined based on laboratory test results, and water and electrolytes should be supplemented as appropriate. Glucose solution and Ringer's solution are dripped intravenously every day, with the addition of vitamin B6, vitamin C, potassium chloride, etc. Maintain daily urine volume above 1000 ml. And give vitamin B1 intramuscular injection. People with malnutrition can be given fat emulsion and amino acids intravenously. Generally, the condition will improve after 2 to 3 days of the above treatment. Pregnant women can try a small amount of liquid food after vomiting stops and symptoms are relieved. If there are no adverse reactions, they can gradually increase the amount of food they eat and adjust the amount of fluid replacement.
