After pregnancy, it is easy to have emotional problems, accompanied by discomfort, boredom, grumpiness and so on. The main reasons are as follows: 1. It may be due to the rapid change in endocrine secretion, especially the rapid change in the secretion of estrogen and androgen during pregnancy, which will easily cause emotional changes, accompanied by symptoms of physical discomfort, such as chest tightness, panic, palpitations, hot flashes, trembling and so on. It may also be accompanied by problems with appetite and sleep, such as nausea, vomiting, difficulty sleeping. 2. It is possible that interpersonal stress, or marital discord, or conflict between mother-in-law and daughter-in-law, or lack of access to exercise, etc., may cause chest tightness, difficulty, discomfort, etc. 3. It is important to exclude somatic diseases, such as having an electrocardiogram, to see if there are changes in the electrocardiogram. If the heart problem is ruled out, only then consider the problem caused by psychological factors. These reasons are more common.
