Snoring starts after pregnancy due to changes in hormone levels that cause congestion and swelling of the mucous membranes. At the same time, with the increase of weight and the accumulation of local fat, the snoring symptom will occur when the airflow through the throat vibrates the uvula. If the snoring symptoms are not very heavy and are not accompanied by breath-holding and apnea, no special treatment can be required. Avoid straining and keep sleeping in side position. If snoring seriously affects the rest of the cohabitants, accompanied by apnea and the symptoms of breath-holding, further treatment is needed. Because of long-term oxygen deprivation, it is more harmful to the body, especially for pregnant women, and also affects the growth and development of the fetus. Sleep monitoring should be improved and ventilator treatment may be given depending on the situation. After the delivery is over and the weight is normalized or reduced, the snoring symptoms will be reduced or disappear.
