What are the health knowledge about constipation?

Common sense of life and health care for constipation: 1, drink more yogurt. The lactic acid bacteria used in yogurt production can promote the proliferation of beneficial lactic acid bacteria in large intestine and inhibit the proliferation of harmful bacteria. At the same time, lactic acid bacteria can also improve immunity and sterilize, making it difficult for Escherichia coli to reproduce. 2. Drink water early in the morning. After getting up in the morning, drink 2 glasses of water (about 500 ml). At this time, 80% of the water is absorbed by the small intestine and 10% by the large intestine, which can effectively promote defecation. People who don't like drinking water can also try to drink drinks with good taste and high water content such as milk and fruit juice. In addition, cold water is more irritating to the intestines, so it is more conducive to smooth defecation. For many years, I have been drinking warm water that naturally cools after boiling that day. I should drink at least 8~ 10 cups every day, or cassia seed tea and green tea, and insist on drinking a cup of boiled water every night before going to bed, when I wake up in the middle of the night and after getting up in the morning. 3. eat apples. Experiments show that apple pectin can increase lactic acid bacteria in the intestine, so it can clean the intestine. Apple contains water-soluble fiber commonly known as "pectin", which has strong water-retaining ability and can absorb water equivalent to 30 times the weight of the fiber itself. Pectin is mostly concentrated in the skin and the joint between pulp and skin. Therefore, when you are constipated, you might as well eat apples that are not peeled.
