When hair loss occurs during pregnancy, it is advisable to seek medical attention and improve tests such as blood count, blood sugar, thyroid function, etc. It is recommended to eat more iron-rich foods, such as animal liver, blood products, spinach, dates, etc., and pay attention to balanced nutrition and no partial diet. Pregnancy can also lead to abnormal blood glucose, and abnormal blood glucose can lead to diffuse hair loss, which needs to be monitored and controlled. Patients may suffer from hair loss due to abnormal thyroid function, which must be treated under the guidance of a doctor. It is also necessary to avoid stress and anxiety during pregnancy, to take rest and not to stay up late.
