If you are exposed to external factors or improper diet and nutrition during the breastfeeding period, it will often lead to an increase in the rate of maternal illness. There are often the following reasons: 1, mental and psychological factors: insufficient rest and sleep at this particular stage, coupled with the worry about the child and their own health, causes anxiety and tension, which seriously affects sleep, and then dizziness occurs; 2, nutritional deficiencies: the most common is iron-deficiency anemia during breastfeeding, which leads to a decrease in hemoglobin and a decrease in the oxygen-carrying function of the blood, which in turn leads to lethargy and dizziness. So nutritional status and iron deficiency anemia are also one of the most fundamental and major etiological factors of dizziness. If dizziness occurs during breastfeeding, it is necessary to check yourself for certain diseases, adjust your mental and psychological state, take care of nutrition and regulate your mental structure. If dizziness occurs on the basis of a good night’s sleep, it is necessary to consult a doctor in a timely manner, except for pathologic factors, and to treat it in time, so as not to affect your health.
