What are the symptoms of digestive enzyme deficiency?

The main symptoms of digestive enzyme deficiency include: 1. Indigestion: Food cannot be adequately digested, leading to symptoms such as bloating, belching, nausea, and vomiting. In severe cases, it may affect appetite, causing reduced appetite or anorexia. 2. Abdominal distension and diarrhea: Undigested food accumulates in the intestines, causing bloating. At the same time, intestinal bacteria may break down food residue, potentially causing diarrhea, with food particles and oil droplets possibly present in the stool. 3. Malnutrition: Long-term deficiency of digestive enzymes can impair nutrient absorption, resulting in weight loss, emaciation, anemia, and other symptoms of malnutrition. 4. Other symptoms: Such as acid reflux, discomfort or pain in the upper abdomen, constipation, and others may also occur concurrently.
