The normal color of stool is usually yellow or dark yellow, and the shape is dry and definable. 1. Normal color of stool: Generally speaking, the color of young children’s stool is mainly yellow, and the color of adults’ stool is mainly dark yellow. As the color of stool is greatly influenced by diet, it cannot be judged simply by color. If the color of stool is tarry, patients should pay attention to the possibility of gastrointestinal bleeding, and promptly carry out stool routine and fecal occult blood tests. 2. Normal shape of stool: Generally speaking, the stool is dry but not thin, and the shape of normal stool is stereotyped. Usually too thin stool is more common in patients with acute and chronic enteritis, while too dry stool is more common in patients with constipation and poor gastrointestinal dynamics. It is recommended that once patients find abnormal stools, they should consult a doctor and choose the appropriate treatment and medication under the doctor’s guidance to avoid delaying their condition.
