Sitting on the moon during the higher incidence of hemorrhoids, caused by the main constipation, there are several reasons: 1, a single diet: sparse rice and eggs, fruits and vegetables less. After the young women sitting on the moon, too many over to give guidance, tell what what can not eat, and finally left with millet and eggs, vegetables and fruits have become taboo, resulting in constipation occurs. Drink thin as usual cause constipation, because the amount of water will not go from the stool, but from the urine. Plant fiber can stimulate intestinal peristalsis, reduce constipation. 2, less activity, bedridden time is too long: most of the bedridden patients have constipation, because the upright position, in favor of food in the role of gravity to move down, reduce the food in the intestinal tract time is conducive to the prevention of constipation. 3, the indoor temperature is too high, the maternal body is weak and sweaty, coupled with the baby breastfeeding, the body is not enough water, so the indoor temperature should not be too high, while replenishing adequate water in a timely manner.
