Hi, Thanks for posting your query. Let me know the cause of jaundice, his liver function test status, ultrasound imaging study. There may be chances of relapse in case of hepatitis A, Hepatitis B and obstructive jaundice. In obstructive jaundice, until unless the obstruction is relieved there is high chances of relapse. Vomiting may be due to liver dysfunction or may be due to upper gastro-intestinal tract pathology. You should again consult with your treating doctors and take proper treatment. You should also take anti-emetics and potassium rich supplements. Keep keen eyes on the hydration of the patients. Take care, Dr. Mayank Bhargava
