Morning sickness and its causes

Morning sickness is a type of early pregnancy reaction. As a result, vomiting occurs. I was eating peacefully, but when I smelled the food I felt nauseous and wanted to vomit. Appetite completely disappeared, weight was lost, and most had various types of headaches. Because after a woman becomes pregnant, the testosterone in her body increases, which can easily cause nausea and vomiting. In addition, during pregnancy, the pregnant woman's body will secrete a large amount of luteinizing hormone to stabilize the uterus and reduce the contraction of the uterine smooth muscle, but at the same time it will also affect the intestinal peristalsis of the gastrointestinal smooth muscle, causing indigestion, nausea, vomiting, acid reflux and other symptoms.

When does morning sickness start during pregnancy?

Morning sickness is just one type of early pregnancy reaction. Generally, nausea, vomiting, loss of appetite, sleepiness, fatigue and other early pregnancy reactions will appear around 40 days of pregnancy. Early pregnancy reactions vary from person to person. Some people have no early pregnancy reactions or the manifestations are not very obvious. Some people's early pregnancy reactions such as vomiting are severe. Therefore, vomiting is not common for every pregnant woman.

Many women do not realize they are pregnant at first until they experience morning sickness and other symptoms, then they realize they might be pregnant. Therefore, morning sickness is not a bad thing. Although it will make pregnant women uncomfortable, some people's morning sickness symptoms will be relatively mild and will be fine after vomiting for a day or two, but for many people, it will last for a longer time.
