Patient's question:
I have an itchy lower body, and my underwear is always yellow. What's going on? How long into the pregnancy do nausea and vomiting start?Doctor's answer:
Generally, in the early stages of pregnancy (around six weeks post-menstruation), the levels of human chorionic gonadotropin (HCG) in a pregnant woman's body increase, while gastric acid secretion decreases and gastric emptying time extends. This leads to a series of symptoms such as dizziness and fatigue, loss of appetite, a preference for sour foods or aversion to greasy and nausea, and morning vomiting, collectively known as early pregnancy symptoms. These symptoms usually do not require special treatment. After the 12th week of pregnancy, as the levels of HCG in the body decline, the symptoms often naturally disappear, and appetite returns to normal.
