Patient's question:
NoDoctor's answer:
After a woman becomes pregnant, the placenta secretes human chorionic gonadotropin (hCG), which inhibits gastric acid secretion. The reduction in 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. Subsequently, these symptoms naturally disappear. However, some may persist for a longer period, leading to a lack of interest in eating.
