Acidosis in pregnant women will be followed by symptoms of fatigue, weakness and thirst in the early stage, and will also be accompanied by nausea, vomiting, dry mouth, dry skin mucosa, decreased blood pressure, polyuria and headache. Acidosis in pregnant women is common in patients with severe early pregnancy reactions. This is because some pregnant women have severe vomiting in the early stage and cannot eat normally, so the fat in their bodies will become a substitute, and the concentration of ketone bodies increases when there is too much fat decomposition, and when too much acid contained in ketone bodies accumulates in the blood, it can cause acidosis due to the imbalance of normal blood acidity and acidity. In addition, poor glycemic control in gestational diabetes can also easily induce ketoacidosis. In general, when acidosis is detected, it is necessary to consult a doctor in a timely manner to clarify the cause of the disease and provide targeted treatment, as well as to correct metabolic disorders. If it is caused by early pregnancy reaction, the first thing to do is to ensure sufficient daily caloric intake, mild nausea and vomiting can be relieved by small and frequent meals and taking vitamin B6 and other drugs. For more serious nausea and vomiting that have affected normal eating, hospitalization is recommended. If gestational diabetes is caused by poor blood glucose control, it is recommended to consult an endocrinologist to assess the need for medication to control blood glucose.
