Eating thioglycollate aluminum suspension gel after gastric polyp removal is to protect the gastric mucosa. After the removal of gastric polyps, the gastric mucosa will have incision damage, the barrier function of the gastric mucosa is damaged, the secretion of gastric acid is increased, and a large number of hydrogen ions in the stomach will stimulate the damaged parts of the stomach, damaging the blood vessels and mucous membranes and causing corrosion. In addition to gastric acid in the stomach there is also pepsin, as well as pathogenic microorganisms, and these damaging substances will cause damage to the gastric mucosal epithelial cells. Thioglycolla suspension gel is a very good neutralizer of gastric acid, can neutralize gastric acid to reduce the damage caused by gastric acid, and can be attached to the gastric mucosa, to a certain extent, blocking pepsin and other damaging substances on the gastric mucosa invasion. Therefore, after the removal of gastric polyps, eating aluminum thioglycollate suspension gel can be the barrier of the gastric mucosa, the gastric mucosa damage regeneration plays a great role in protection.
