Constipation is a common hidden problem for the vast majority of people, although constipation is not a big disease, but long-term constipation is not treated in time, there will be many hazards, even life-threatening. 1, face damage: long-term constipation, fecal matter for a long time to stay in the intestinal tract, abnormal fermentation, corruption and produce a large number of toxins, easy to lead to metabolic disorders in the body, endocrine disorders and imbalance of micronutrients, which will appear skin pigmentation, facial darkness and roughness, and chloasma, acne and acne and so on. 2, anal disease: feces is too dry and hard, can lead to abdominal pressure rises, make the anal vein blood circulation is not good, appear hemorrhoids, prolapse (rectal prolapse), anal fissure and so on. Prolonged straining to defecate makes the pressure of rectal upper and lower venous plexus increase for a long period of time, resulting in the smooth muscle fibers and elastic connective tissue surrounding the outside of the gradually destroyed, the veins gradually varicose and become hemorrhoids. Prolonged constipation, due to dry and hard stools, stool force discharge, will cause anal canal skin cracks, cracks secondary bacterial infection, so it is not easy to heal the formation of anal fissure. 3, secondary anemia: hemorrhoids, anal fissure patients will have bleeding when defecating, less than the blood drops after defecation, more than the spray of blood, long-term anemia will be triggered. General development is slow, early no symptoms or mild symptoms, anemia is more serious or faster progress, there will be pale, fatigue, dizziness, loss of appetite, panic and shortness of breath and other symptoms, sitting for a long time squatting suddenly stand up, can lead to collapse or fainting. If there is blood in the stool, you should consult a doctor in time to avoid excessive bleeding leading to more adverse consequences. 4, induce cancer: long-term constipation can make intestinal bacteria multiply, fermentation process is enhanced, and more carcinogens are produced. Long-term stimulation of intestinal tract by carcinogens can induce colorectal cancer, and there is also the possibility of inducing breast cancer. 5, induce cerebral hemorrhage: when constipation, defecation force, abdominal wall muscle contraction, abdominal pressure rises, thus compression of intra-abdominal veins so that the venous blood flow increases, the burden on the heart increases, and blood pressure rises. For hypertensive patients have the risk of cerebral hemorrhage. 6, induced angina: defecation can reflexively cause coronary artery spasm, resulting in myocardial ischemia and hypoxia, for patients with coronary artery disease, easy to induce angina pectoris or myocardial infarction.
