Constipation and colorectal cancer are two different diseases, but they are related. Frequent constipation can increase the risk of colorectal cancer because long-term constipation can lead to restricted toxin elimination from the body. Some of the foods we eat daily, including proteins, fats, and sugars, decompose in the intestine into substances like ammonia, benzene, and phenol, which have carcinogenic effects. Therefore, people who are frequently constipated may face an increased risk of colorectal cancer. Thus, to address frequent constipation, it is important to solve constipation issues. One's diet should be light, incorporating more fruits and vegetables, drinking more water, and exercising more, to resolve the issues of constipation.
