Drowsiness is one of the pregnancy reactions, which usually starts to appear after 6 weeks of menopause and lasts until about 12 weeks of pregnancy and disappears on its own. During pregnancy, the hormones in the body change, the metabolism speed up, the body calories have to be consumed more than usual, pregnant women will often feel weak and tired. Don’t put too much pressure on yourself during this period, as long as you ensure a balanced nutrition in your diet every day and eat less and more, the fetus will not be affected too much. Drowsiness is a common reaction in early pregnancy, but drowsiness is not a criterion to determine pregnancy, because many women do not necessarily experience drowsiness or even any abnormal discomfort after pregnancy. Therefore, it is recommended to consider testing with an early pregnancy test after a week’s delay in menstruation. It is necessary to identify physiological drowsiness or pathological drowsiness in time. Physiological drowsiness can disappear on its own with the end of early pregnancy reaction and does not require any intervention or treatment. Pathological drowsiness is most common in brain disorders and is often characterized by uncontrollable bouts of sleep that last for several hours or even days at a time. It may be related to obesity and elevated blood sugar during pregnancy. If the drowsiness is due to pathological factors, the primary disease should be actively controlled, such as strengthening exercise and closely monitoring blood sugar.
