A patient with advanced chronic mesenteric ischemia is most likely to be:

A patient with advanced chronic mesenteric ischemia typically experiences inadequate blood flow to the intestines, leading to malnutrition. The condition often results in abdominal pain after eating, which can result in the avoidance of food. Over time, this can lead to weight loss and nutritional deficiencies as the patient becomes reluctant to eat due to the pain associated with digestion.

Additionally, chronic mesenteric ischemia is often linked with underlying vascular diseases that can further predispose individuals to malnourishment. This means they may struggle to absorb essential nutrients, leading to a well-documented risk of malnutrition in these patients. Well-nourished or hydrated states are less likely given the circumstances surrounding their condition. Patients may not only lack nourishment, but their dietary habits will reflect a response to their ischemic symptoms, compounding the problem.
