Dad has A-fib?

Diverticulitis would cause a pain in the Left lower abdomen when palpated (pushed on). These are just small pockets in the intestine that are inflamed, he should avoid nuts, corn, anything that could possibly get stuck and irritate these sacs.

This should resolve and become Diverticulosis (just having the sacs with no infection.

Crohns disease effects the entire large intestine, and has lots of dietary restrictions, and is not cureable. He would poop 3 to 4 times a day and it would float,(this indicates undigested fats in stool) and may have small amounts of blood. He should have his stool tested for fats.

Nausea isn't uncommon with A-fib. The real danger with it initially is clot formation...

Thanks Canan!

In reading this again after your reply I felt I left out a little!

Diverticulosis would also cause an increase in White Blood Cells since it is an infection.

It would be very important to find out first from the treating physician exactly which disorder, or possibly another, before treatment and dietary changes are made.

Like I said before Crohns had many dietary restriction, as does diverticultitis but the main this with that is to avoid the irritating foods and increase fiber-basically prevent constipation.

The symptoms you're describing could be of course one or the other (or even all of them). Aterial-fib can cause dizzyness, weakness, pain, and if cardiac blood circulation is sufficiently disrupted, vomitting and other serious symptoms can occur. The heart has two upper chamber (Atriums) and two lower chambers (Ventricles).

A-fib is common and although it can be the precursor to other medical problems (see below) many people have it without knowing for a long time. A good indicator of it is a (consistently) irregular heartrate. But since your father is taking medications for it, his a-fib may be exacerbating (getting worse). Depending on his heart rate, it means the upper electrical conduction in his heart is getting further disrupted and lower parts of the heart are taking over to initiate the beating of the heart (perhaps the Bundle-of-His, purkinje fiber etc. )

Most serious medical conditions caused by A-fib are blood clots that then can cause pulmonary embolism, myocardial infarction - heart attack - or cervical vascular "accidents" - stroke. Gastrointestinal problems are complex in their own right and I believe a medical student/future physician was giving you quite good (and FREE information! But ask your questions also to the treating physicians and the more you research the subject the more informed you guys can decide on treatment and preventation. Good luck!
