Is there a vascular disorder that causes severe raynauds w/ digital ischemic, partial adrenal insuff, and multi-wk episodes of ovarian failure, carb intol, bradycardia, & sev. constip (sibo etc.)?

Rheum and endo: Scleroderma comes to mind from what you've described. Many autoimmune rheumatologic disorders are associated with autoimmune endocrine disorders, most common are hypothyroidism (hashimotos); also adrenal, ovarian. At age 45 you could be perimenopausal. Acth/cortisol ratio is not reliable. Need Cortrosyn stim test. And a rheumatologist and endocrinologist to sort things out.

Not likely: It is unlikely that you have a single disorder causing all of the above. However, from the data it sounds like you have a primary rheumatologic disorder ( which may cause vasculitis). Some of these other issues may be distractors.

Check out endocrine : These systemic issues would seem to hint of more than a vascular disorder. Would look into your endocrine system (hormones), as features of adrenal insufficiency, and thyroid insufficiency (bradycardia and constipation) seem to be at play (pituitary might be the common denominator). Raynauds canoccurfora for primary or secondary reasons. In absence of a known ctd, shd rule out hormone issues.
