After pregnancy, women may experience slight changes in their body organs, such as a slightly faster heart rate due to estrogen levels. If you feel palpitations and panic attacks that affect your daily life, they may be caused by poor rest during this period. An electrocardiogram can be done to check if there is any disorder of blood supply to the heart muscle, such as myocardial ischemia. In addition, it is also necessary to check whether there is anemia, because during the first trimester there is a pregnancy reaction, some people may not eat well, resulting in a decrease in body mass and a slight anemia. Be sure to enhance nutrition and eat more red dates, peanuts and wolfberry-type foods. If there is pathological myocardial ischemia, use the medication for treatment according to the doctor’s instruction.
