Probiotics for functional dyspepsia are effective for some patients. Probiotics contain a variety of intestinal probiotics, such as Bifidobacterium or Lactobacillus acidophilus, which can supplement the intestinal physiological flora, re-establish the intestinal micro-ecological balance and reduce the reproduction of pathogenic bacteria. For some patients, it can improve the symptoms of postprandial discomfort, such as abdominal distension, stomach pain, poor appetite and poor digestion. It is more effective when used in combination with other gastro-dynamic drugs and digestive enzymes.
