Constipation in adolescents and young people who cannot pass stool for a long period of time will lead to accumulation of toxins, intestinal diseases, and cardiovascular and cerebrovascular diseases. 1. Toxin accumulation: Stools are worthless residues of food and toxins, which need to be discharged on a regular basis. Prolonged constipation will lead to reabsorption of water and toxins from the stools in the intestinal tract. 2. Intestinal diseases: long-term constipation in adolescents leads to hard and dry stools, squeezing the blood vessels of the intestinal wall, resulting in impaired blood circulation, easy to form enteritis, hemorrhoids and other intestinal diseases. 3. Cardiovascular diseases: long-term constipation, leading to difficulties in discharging stools, abdominal force, compression of blood vessels, which can easily lead to increased blood pressure, blood clots, triggering a variety of cardiovascular and cerebrovascular diseases.
