Hi, Sarah, your father has I.B.S. suffering with constipation
, like wise he had constipation and diarrhea with lactulose
now he has fainted and had fever
, cough with sputum
. The doctors treatment is good, if he didn't recover from fever, you can consult him for follow up.
Hi may need to have blood examination for confirmation of the type of fever. Accordingly he may be treated. Thank you.
