HELLO, YES, IT'S TYPHOID. FEVER IS NOT PRESENT DUE TO PREVIOUS TREATMENT. HIGHER ANTIBIOTICS IN INJECTABLE FORM   FOR THREE DAYS AFTER AST( AFTER SENSITIVITY TEST). DIET IS VERY IMPORTANT. ONLY LIQUID DIET FOR FIVE TO SEVEN DAYS. EG, DISSOLVE BISCUITS IN MILK OR TEA. ROTI WITH MILK  PERFECTLY MESSED. RATHER CHURNED LIKE WISE. THAN SLOWLY SEMI SOLID LIKE KHICHARI, PORRIDGE WITH MILK.   DIET IS ADVISABLE BECAUSE THE ULCERS IN INTESTINE ARE FORMED DUE TO THYROID DISORDER AS MUCOSA OF GUT BECOMES ERRODADE SO ANYTHING HARD CAN CAUSE RUPTURE OF ULCERS MAY LEAD TO BLOOD VOMITING. DURING THIS YOU HAVE TO TAKE  COMPLETE REST. I HOPE THIS HELPS YOU. O.K, BYE.
