What adults eat and what they poop may be due to physiological factors such as food types and eating habits, as well as pathological factors such as gastrointestinal dysfunction and indigestion. 1. Physiological factors: certain foods that are not easily digested by the digestive tract, such as mushrooms like enoki mushrooms and fungus, or foods rich in dietary fiber like spinach and corns, are not easily digested after eating, leading to the excretion of the food itself. If the food is not completely chewed when eating and swallowed, it is not easy to be digested by the digestive tract, and the phenomenon of what to eat and what to pull may also occur. 2. Pathological factors: mainly gastrointestinal diseases, such as gastrointestinal dysfunction, dyspepsia, gastroenteritis, gastrointestinal phytophysiopathy, gastrointestinal tumors, etc., which can affect the digestive and absorptive functions of the gastrointestinal tract, resulting in food not being completely digested and absorbed after entering the digestive tract, causing patients to experience the symptom of “what to eat what to poop”. If patients have long-term or recurrent symptoms of what to eat and what to poop, it is recommended to seek timely medical treatment to identify the cause of the disease and carry out targeted treatment to avoid delaying the condition.
