Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice.
As I was going through the medical history of your 60 year old husband Tom, I noted that he has been diagnosed with
diverticulitis. This is associated with
frequent abdominal pain and sometimes with
chills especially if the patient is not following the diet as advised by his doctor.
So, I highly recommend to consult with his gastroenterologist in order to re-evaluate his case better and rule out a possible
diverticulosis attack.
Give plenty of plain water and liquid foods including ice chips, broth, gelatin, etc. Advise to take medium fiber foods like milk, yogurt, cheese, pasta, bread, noodles, etc.
But most important is to consult with gastroenterologist and run a few diagnostic tests to evaluate his case better (including
colonoscopy, ct-scan, abdominal ultrasound; urine analysis).
Hope I have answered your query. Let me know if I can assist you further.
