Untreated severe gastroparesis can lead to complications such as malnutrition, dehydration, electrolyte disorders and can be life-threatening, so prompt and standardized treatment is required. Severe gastroparesis is generally not self-healing. If left untreated, patients will not only experience worsening gastrointestinal symptoms such as vomiting, abdominal distension and abdominal pain, but will also suffer from serious complications such as dehydration (even shock), electrolyte disorders (alkalosis is common), and malnutrition (malnutrition, even cachexia), which can be life-threatening. Therefore, people with severe gastroparesis must be treated under the guidance of a doctor in a timely manner in order to strive for a good prognosis, and should not blindly dispose of the condition on their own, as this may delay treatment and cause adverse consequences.
