Is it normal for a type 1 diabetic to have high/low swings in sugar levels 5mos after liver resection?

Brittle. Type 1 insulin dependent diabetes is often brittle with swings in blood sugars at times without rhyme or reason. The liver does play an important role in glucose metabolism, but I doubt that partial resection of the liver is a major cause of the blood sugar swings. A diabetologist or endocrinologist is better qualified to answer your question. Addition of some of the newer diabetic meds may help.
