Fecal matter is mainly accumulated in the colon and rectum, and since this part of the intestine no longer has a significant digestive function, even if you don’t eat breakfast, there will be no digestion of fecal matter in the colon and rectum. However, if you do not eat breakfast, the lack of food stimulation in the intestinal tract will lead to a decrease in intestinal peristaltic capacity, resulting in a decrease in the ability of the colon and rectum to pass stool, and the amount of stool passed will decrease. At the same time, because the colon and rectum have the ability to absorb water, if feces accumulate in the colon and rectum for a long time, a large amount of water will be reabsorbed, resulting in dry stools. Therefore, if you do not eat breakfast, it is easy to reduce the total amount of excreted stool, but it is not the same thing as digesting feces. Long-term skipping breakfast can have a negative impact on health, so patients are advised to eat on time and regularly.
