Yes thank you, I have read all of the posts and the one from @nogginquest provides a guarded but very positive prospect.
Presently my wife is suffering a fair bit of mid-back pain and is now taking 4 doses of diclofenac 50 mg suppositories a day (every 6 hours) and potassium chloride as her potassium levels have been low . She also has diarrhea and was given a prescription for some pancreatic enzymes. Interesting to note that she hasn't shown any signs of yellowing skin or had fatty substances in her stools. Other than the diarrhea her energy levels are dropping off and she is still loosing some weight, but is trying to eat well.
We were both on the Ketogenic lifestyle (low carbs and sugars replaced with high fats. protein and lots of vegetables ) as her doctor told her last year after knee replacement surgery that it would help to shed some extra pounds. To date she has lost 65 lbs, now down to 175 lbs, however the last few months she has lost most of the weight, probably more related to the cancer than the lifestyle. Her medical Oncologist advised her to get off the Keto lifestyle and eat a well balanced diet.
We will be talking to the dietitian tomorrow so will have a better idea as to what is best to eat moving forward.
