If the examination during the preparation period is normal, simple anger at the beginning of pregnancy usually does not affect the baby; however, if the pregnant woman has a history of multiple miscarriages or cervical insufficiency, etc., anger may lead to an increased risk of preterm miscarriage or miscarriage. We should pay more attention to the causes of easy anger after pregnancy than to the effects of anger on the baby. After pregnancy, due to changes in hormone levels in the body and early pregnancy reaction and other symptoms will cause psychological changes in pregnant women, such as moodiness, irritability, fear, anxiety, crying, memory loss, sleep disorders and other psychological changes, mostly in the 6-10 weeks of pregnancy, and will gradually ease, is a normal phenomenon, pregnant women need to formalize this series of psychological changes, and pay attention to self-regulation, in most cases will not have an impact on the baby. In most cases, it will not affect the baby. If the above psychological changes are aggravated, such as excessive anxiety, nervousness, irritability, crying and difficulty in stopping, sleep disorder and so on for a longer period of time, you need to be alert to the occurrence of depression. If you find that your personality changes after pregnancy and you show signs of accelerated metabolism such as impatience, anxiety, irritability, excessive sweating and panic, you need to be alert to the occurrence of hyperthyroidism (hyperthyroidism). If the early pregnancy anger is caused by depression, serious psychological changes can increase the baby’s activity, leading to premature birth, stillbirth or baby malformation, and affect the development of the baby’s intelligence, language and other brain functions, and after birth, the baby is prone to split personality or emotional disorders. In case of hyperthyroidism, the risk of miscarriage, preterm delivery, stillbirth, low birth weight baby, hypertension during pregnancy, thyroid crisis and congestive heart failure in pregnant women increases if the condition is mild or can be controlled by treatment. In summary, anger in early pregnancy is in most cases a normal physiological change during pregnancy, which has no effect on the baby, but pregnant women need to correctly understand the physical and psychological changes after pregnancy, and take measures to cope with them. If the degree of emotional changes such as anger is heavy and prolonged, or even if other psychological changes occur, depression or hyperthyroidism cannot be ruled out, prompt medical attention is needed to clarify the cause and treatment to avoid increasing the risk of miscarriage, premature birth, stillbirth and stillbirth of the baby.
