Mild nausea and vomiting in early pregnancy is the most common symptom during early pregnancy to 16 weeks of gestation. If the change is only mild, the diet can be changed to a small number of meals and taking vitamin B6 can often relieve it. If frequent nausea and vomiting occur, leading to blood, urine and water-electrolyte disorders, it is what we call severe pregnancy vomiting, which can be treated by hospitalization, fasting for 2-3 days, daily rehydration with Ringer’s solution, glucose, vitamin B6, vitamin C, and intramuscular vitamin B1 injection. If acidosis is present in the blood check, sodium bicarbonate can be supplemented appropriately. Those with low potassium can also be supplemented with potassium, and those with malnutrition can also be given intravenous injections of amino acid and fatty milk. After treatment, the vomiting stops and the symptoms are reduced, you can try to eat and drink, and if the effect is not good, you can also apply Chinese medicine to the umbilical cord to assist in the treatment.
