How long does it take for gastric paresis to return to normal?

Gastroparesis usually returns to normal within 3–5 weeks. It can be caused by various factors, and if the condition is severe, recovery may take longer, depending on the individual patient's condition.

Gastroparesis refers to impaired gastric emptying due to dysfunction of the stomach's nerves and muscles. It is commonly caused by abdominal surgery or diabetes. Since the underlying causes vary, recovery times also differ. Most cases of gastroparesis result from abdominal surgeries—for example, during a partial gastrectomy, the vagus nerve may be severed, impairing normal gastric motility and emptying. Additionally, prolonged exposure of organs during surgery can lead to reduced function and delayed gastric emptying. If the condition is mild, normal function typically resumes within 3–5 weeks after surgery. However, in more severe cases, recovery may take longer, requiring active adherence to medical treatment recommendations. Diabetes is another common cause of gastroparesis; improvement can only occur once blood glucose levels are maintained within a normal range. If blood sugar control is difficult, recovery from gastroparesis will be prolonged, with no fixed recovery timeline—it depends entirely on the clinical course.

Moreover, other digestive system disorders can also lead to gastroparesis. Treating the underlying disease is essential; once the primary condition is cured or improved, gastroparesis symptoms gradually resolve. Patients with gastroparesis should actively cooperate with their physicians' treatments to promote faster recovery of gastric function.
