Normal healthy adult stools are generally banana-like, dark yellow in color, with a smooth surface and soft stools. The shape of the stool can often determine a person’s health status, so doctors often pay attention to the condition of the stool during consultations. The thinning of the stool is a warning against intestinal occupational disease. Sticky and unformed stools are often considered to be due to spleen deficiency and poor transportation. Watery stools often indicate the presence of enteritis, intestinal flora imbalance, and parasitic infections. Hard, lumpy stools are usually considered to have accumulated in the intestinal tract for a long time, and the water is excessively absorbed by the intestinal tract.
