Hiatus hernia with erosive reflux esopha

My daughter has been suffering with vomitings continuously from 5th month of her pregnancy, she delivered healthy baby in Dec 2020, but still her vomitings are not subsiding. Initially we thought that vomitings are because of pregnancy but recently after consulting gasterologist endoscopy is performed  attaching the report. Kindly suggest any proper treatment She would vomit everything including water whenever she enters the vomiting phase, sometimes medication will control but mostly it  is not controlable. This vomiting phase would be present for 7-10 days She also complains severe spine pain and stomach pain during the vomiting phase, massage on back is giving temporary relief from back pain. She is currently using the medication suggested by gasterologist from 3 days but there is no improvement. Is there any surgery required for this case ?
