The process of giving birth to a child is a very exhausting and physical process, so it is a very common and imaginative expression to say that you stay for three years after giving birth. Most women experience memory loss and slow reactions after giving birth, which is a normal physiological phenomenon. Usually, as maternity leave ends and you actively participate in work and interact with people, this feeling will gradually decrease. However, if this symptom is more than half a year, you need to consider the possibility of postpartum depression. You can go to the psychiatric department of a regular hospital for examination to see if there is any postpartum depression, and you can take oral antidepressants for treatment. Secondly, hormonal changes in the body, especially sex hormone changes, or low thyroid function, may also cause this condition. You can also go to the endocrinology department for examination to see if there is any memory loss or slow reaction caused by endocrine disorders.
