Chronically elevated cortisol causes weight gain.

Is it true that Chronically elevated cortisol causes weight gain?

Unclear. The retrieved items consistently associate chronic cortisol excess with weight gain: a reference article lists Cushing's syndrome among pathological causes of weight gain, and three case reports or observational studies describe weight gain or obesity in patients with hypercortisolism. None of these items establishes a general causal link at the strength the claim asserts; they provide only partial, largely case-level support.
