Functional dyspepsia is very common in life, especially among adolescents, which can lead to a further decrease in appetite. Food accumulates in the gastrointestinal tract for a long time, making it difficult to move downwards, causing stomach and intestinal bloating. Over time, it affects the appetite, and the patient's mental and nutritional status will be impacted. It is necessary to use some digestive aids and drugs that promote gastrointestinal motility in a timely manner. Attention should also be paid to dietary adjustments, eating regular meals in fixed quantities, and eating more soft, easily digestible food. Try to eat less raw, cold, or spicy food.
