Detailed Answer:
Your research has revealed appropriate answers. Postprandial hyperadrenergic reaction is a medical entity known to pose challenges to diagnosis and treatment. It can be a perplexing condition.

It is related to a couple medical conditions.

One of them is post-bariatric surgery. Has the person you are referring to, undergone any type of weight loss surgery? There is a phenomenon called dumping syndrome that presents just like this, some time after kind of surgeries (such as gastric bypass).

The other is Reactive hypoglycemia. This occurs in individuals with pre diabetes or early type 2 diabetes. Typically these individuals have insulin resistance and are overweight/obese. There is a rise in blood glucose levels after meals, and owing to a exuberant insulin response to the elevation in blood glucoses, a sharp fall in glucose levels follows. This rate of fall in blood glucose concentrations has been associated with the development of these hyperadrenergic symptoms. They mimic low blood glucose reactions even though there is no true hypoglycemia (blood glucose below 70 mg/dl). it is just the rapid rise followed by the quick dip in the blood sugar levels that causes these frustrating symptoms.

To manage these, first the diagnosis needs to be ascertained. Once that is clear, treatment includes seeing a dietitian who will advise eating frequent (every three hours) small meals or snacks, consuming foods high in fiber, avoiding foods high in sugar. A regular exercise regimen have been recommended. If dietary modification is not successful in reducing symptoms, some advocate a trial of a type of medication called alpha-glucosidase inhibitors to delay carbohydrate absorption and thereby reduce the insulin response to a meal.

There are 2 types of specialists who deal with this. Endocrinologists and gastroenterologists.
