The reason why gastric ulcer does not want to eat, there are two main reasons: 1, its own ulcer if repeated symptoms do not see relief, or has infiltrated the submucosa, most prone to gastrointestinal dysfunction, some may appear stomach cramps. This situation can lead to gastrointestinal indigestion, which causes slow gastric emptying, resulting in a poorer diet, epigastric discomfort, bloating, poor nausea, abdominal pain, so it can lead to not wanting to eat. 2. Its own gastric ulcer can easily lead to vagal nerve excitation, and the plant nerves often become dysregulated. The body has a self-protective role, and this protection often plays a restorative role in ulcer disease, but will lead to not want to eat. This not wanting to eat has the effect of less damage to the organism, reducing the effect of damage to the stomach, thus reducing the stimulation of the ulcer and effectively speeding up the recovery time of the ulcer.
