Detailed Answer:
Hi.
Thanks for your query and an elucidate history.

To recapitulate: Female / 79 - 5 abscesses in sigmoid 3 years ago - 6 inches colon removed - Surgeon said could not get them all - Main C/O spontaneous diarrhea on eating almost anything, bloating, flatulence - Hospitalized for 3 months - lost 40 lbs in 2 months - blood clots - Paranoid - Immodium and Gas Plus - stopped Lovaza (fish oil)- same - good cardiac part with multiple problems treated -

May I please know a few things please :
May I please know the histo-pathology report of the colon that was removed ?
What is the present diagnosis that your Doctors have been thinking of ?
You were admitted for so long hence all the investigations must have been done.
What is the opinion and treatment given by the Gastroenterologist ?
How much Immodium is helping ?
Which foods suit you ?

This will help me to help you more.
You may please attach important reports with this query. YYYY@YYYY

My thoughts till I get the reports and additional information:
Spontaneous diarrhea on eating is suggestive of Irritable bowel, the cause of which has to be found or must have already been found.

Since the colon has abscesses, this indicates you had infection of the intestinal tract. Bloating and flatulence also suggest the same things in addition to the other causes that may cause it like- certain foods and beverages, aerophagia meaning inadvertent swallowing of air due to anxiety and stress, disturbed Bacterial flora.

As a general guideline:
-Take Prebiotic and probiotics available in the Pharmacy.
-Try taking Banana, curd, and other foods and beverages that you must have noticed to cause less or no problem.
-Activated Charcoal ( I hope Gas Plus may be the same - not found the composition on net) 2 tablets 3 times a day.
-You may also try Pancreatic Enzymes 2 tablets to be taken with food.
-A course of oral antibiotics and Metronidazole or Tinidazole for 5 days.

Yet the most important part is the diagnosis; the following things may help us to get the diagnosis if not yet done:
-Repeated examination of stool
-Routine blood and urine test to know the status along with specific tests as may be warranted on clinical evaluation by your Gastroenterologist as specific diseases prevail in particular area of the country you reside which He would be aware of.

-Enteroclysis (Barium study under fluoroscopy, so that the exact transit time, movement of the bowel, strictures, large ulcers or diverticuli any internal fistula can be diagnosed well.
- Capsule endoscopy shows what exactly is the interior of the intestines.
- CT scan of abdomen.

I am sure most of the tests might have been done under the examination, clinical evaluation and guidance of the Gastroenterologist.

Cardiac care to be continued as per your Cardiologist's guidance.

I hope this answer helps you at least in part to start with. I would be really happy to help you in such a situation, which I know is frustrating for the patients, relatives and the Doctor in the same way. Yet with the advent of newer techniques, medicines, better understanding of the diseases has made this possible to get a diagnosis in most of the cases and better cure or at least control of the problems to make life more easy and comfortable.

Please feel free to have more interaction, give me feedback about your reports, condition, improvements, anything tried new, its effects and so on; ask for further relevant queries or if you feel that there is a gap-of-communication.
