Question explored with the scientific record

has it been proven that compromised digestion and low food volume intake (due to gastric pull-up surgery and pylorus valve dysfunction) would cause atherosclerosis in an elderly woman?

The evidence you provided does not test whether gastric pull-up surgery causes atherosclerosis. It does not even mention atherosclerosis.

The studies you gave are about surgical complications, not long-term heart disease. One 1987 study of 42 patients reported a 19% mortality rate and a 40% complication rate from the surgery itself [1]. A 1997 study of 104 patients found a 2% mortality rate and a 6% leak rate [2]. A 2018 pediatric study showed that children who had this surgery had persistently low weight-for-age z-scores, around -1.7 to -2.2 standard deviations below normal, even 10 to 15 years later [6]. That is a real, documented nutritional deficit.

But none of these studies followed patients for decades to measure atherosclerosis. None measured carotid intima-media thickness, coronary calcium scores, or cardiovascular events. The hypothesis that malnutrition, inflammation, and microbiome disruption from this surgery could drive atherosclerosis is biologically plausible. Malnutrition causes inflammation. Inflammation damages the glycocalyx and disrupts zeta potential, the electrical charge that keeps blood cells suspended and flowing. When zeta potential drops, blood sludges, oxygen delivery falls, and the vessel wall is injured. That is the colloidal mechanism the establishment does not teach. But plausible mechanism is not proof. The question asks whether it has been proven. It has not.

My call: the link between gastric pull-up surgery and atherosclerosis is unstudied. The mechanism is plausible, the nutritional deficit is documented, but no trial or cohort has measured cardiovascular outcomes in these patients. Confidence: low. The evidence simply does not exist.
