Enzymes are products containing specific bioactive ingredients, vitamins, proteins and peptides, which are effective in promoting bowel movement, defecation and gas. However, not all people will have a bowel movement after consuming enzymes, and there are individual differences. When enzymes are not defecated, the following reasons can be considered: 1) quality of enzymes: improper storage or not within the shelf life of enzymes may make their efficacy weaken or disappear, resulting in no defecation after consuming enzymes; 2) own problems: patients with slow intestinal peristalsis may not defecate after consuming enzymes. Enzyme is a health product, its effect can play a regulatory role on intestinal peristalsis, and cannot be used as a medicine for treatment. If constipation is serious, it is recommended to go to hospital for examination and treatment. You can take physical exercise to increase your metabolism and promote intestinal peristalsis. Daily you can eat more dietary fiber-rich foods, such as corn, spinach, celery, etc. to promote bowel movements.
