Patient's question:
I have an itchy lower body, and my underwear is always yellow. What's going on? When do pregnancy symptoms usually appear?Doctor's answer:
After a woman becomes pregnant, the placenta secretes human chorionic gonadotropin (hCG), which inhibits the secretion of gastric acid. The reduced amount of gastric acid secretion significantly decreases the activity of digestive enzymes, thereby affecting the pregnant woman's appetite and digestive function. At this time, pregnant women may experience symptoms such as nausea, vomiting, and loss of appetite. Generally, pregnant women exhibit morning sickness, characterized by mild nausea and vomiting in the morning on an empty stomach during the period of 40 to 80 days of pregnancy. This condition naturally subsides afterward, although some may continue to have a lack of appetite for a longer duration.
