Harmful Joy, also known as pregnancy vomiting, is a term used in Chinese medicine to refer to nausea and vomiting in the early stages of pregnancy, which is often severe in the morning when a woman wakes up. It is often severe when waking up in the morning, because it is caused by a woman’s loss of appetite, choice of food, and vomiting after eating, due to the reversal of fetal qi and gastric dysfunction (obstruction of the stomach’s function of passing and descending) after she becomes pregnant. It is generally categorized into physiological and pathological causes. If nausea and vomiting occur during normal pregnancy, there is no need to worry too much about interference if it does not affect the fetus or the pregnant woman. If the nausea and vomiting are severe or due to pathological factors then treatment is required. They can be categorized as causes of liver qi stagnation (poor qi and blood transportation in the liver, emotional depression) and vegetative weakness of the spleen and stomach. 1. Weakness of the spleen and stomach: early pregnancy, vomiting and inappetence, distention and fullness of the epigastrium (abdomen), generalized weakness, dizziness, drowsiness, pale mouth or vomiting of clear saliva, pale tongue, white moss, and weak pulse. This is mostly due to the deficiency of the spleen and stomach, the upward reversal of the qi of the flushing vein, and the failure of the stomach qi to descend. 2. Liver-Qi stagnation: in the early stages of pregnancy, vomiting of bitter or sour water, chest fullness (chest distension and discomfort), dystocia (pain in the area of the ribs), belching (hiccups), sighing, head distension and dizziness, irritable thirst and bitterness, depression, pale tongue with reddish moss, and a slippery pulse. This is mostly due to liver qi stagnation and lack of detachment, liver qi upturning against the stomach, and loss of gastric harmony. Happiness is a normal phenomenon in the early stage of pregnancy, the individual physique is different, whether such symptoms and the severity of the symptoms there are differences, usually recommended to maintain a happy mood, stools. If you experience any of the above symptoms, it is recommended that you seek prompt medical attention to avoid delaying your condition.
