Heavy sweating at night during early pregnancy is a common condition during pregnancy, mainly related to a variety of physiological or pathological factors that lead to excessive sweat secretion by sweat glands. At this time, we should pay more attention to observe whether there are uncomfortable symptoms during pregnancy, pay attention to distinguish the causes and take treatment methods for the symptoms. I. Physiological factors: 1, the external temperature is high: such as air conditioning temperature is set too high, pajamas, bedding thicker, etc., may lead to pregnant women sleep at night feel the body surface temperature rise, accelerate sweat discharge heat dissipation, so that the situation of sleeping dripping sweat, it is recommended to adjust the indoor temperature to a comfortable state, choose the appropriate thickness of pajamas, bedding, etc., usually the situation can be self-relieved; 2, hormone secretion Increase: The hormones such as human chorionic gonadotropin, estrogen and progesterone in pregnant women’s bodies are significantly higher in early pregnancy, which can lead to an increase in metabolism of pregnant women and accelerate sweat secretion, usually more hormone secretion at night than during the day, which can cause pregnant women to sleep heavily at night in early pregnancy, which is a normal physiological phenomenon and does not require special treatment, so pay attention to wiping the sweat clean in time to avoid catching a cold. Second, the pathological factors: 1, fever: early pregnancy if the pregnant women in the night fever, can lead to an increase in body temperature, if at night sleep, the body is in the heat dissipation stage, sweating can significantly increase to help dissipate heat, so that the situation of night sleep dripping sweat, at this time can be accompanied by chills, weakness of the limbs, dizziness and other symptoms. The phenomenon of dripping sweat indicates that the body is continuing to dissipate heat, fever symptoms can gradually improve, if necessary, priority can be given to physical cooling methods, such as forehead cold towels, warm water wipe the armpits, neck and groin area, to assist in increasing the body’s heat dissipation; 2, hyperthyroidism: referred to as hyperthyroidism, if pregnant women in early pregnancy combined with hyperthyroidism, can lead to increased secretion of thyroid hormones, which increases the body’s metabolism, so that The body needs to increase sweat discharge and accelerate heat dissipation to maintain body temperature balance. If thyroid hormone secretion increases during nighttime sleep, pregnant women may experience profuse sweating during nighttime sleep. At this time can be accompanied by accelerated heart rate, easily agitated, hyperphagia, wasting and other symptoms, can strictly follow medical advice to apply vitamin B6, vitamin C injection treatment, or oral methimazole tablet treatment, and at the same time pay attention to avoid the intake of kelp, nori and other foods containing more iodine; 3, tuberculosis: if the early pregnancy combined with tuberculosis, due to the high basal metabolic rate of the body after lunch, most pregnant women with combined tuberculosis can occur after lunch Low fever. If they sleep at night to increase heat dissipation, they may sweat profusely at night, and at the same time, pregnant women with combined tuberculosis may have a long-term cough, coughing sputum, or even blood in the sputum. In this case, treatment should be focused on tuberculosis, and medications such as ethambutol hydrochloride tablets and bedaquiline fumarate tablets can be applied as prescribed by the doctor, and if necessary, pregnancy should be terminated.
