I am one of the few who loves the endocrine chapters. I feel like it is in need of advocation and is very often overlooked. Once you catch the pathways to the organs, to me, it is not that tricky. Cardiology is much more difficult for me to understand. My feeling with endocrine - most people hate it so it needs advocates. Personally, in my family self included, have diabetes, addisons, hypo thyroid, and poly-cycstic ovarian which can fall under ob/gyn or under endocrine from my understanding since poly-cystic can destroy the pancreas. However since the latter affects the pancreas and insulin production, I always think of it under endocrine. It is so difficult to find an effective treatment. Too bad there is not a larger role for RN's when it comes to endocrine, as in my experience, the endocrinologists are like many specialists and have very little time....in general. I'm many years into my hashimotos and still STILL Looking for an endo who actually listens. Most have told me I need to eat fewere hamburgers and for the record, I work out INTENSELY 6 days a week and eat only salad with olive oil dressing and chicken breast most days. Still I gain weight even on medication. I know from my experience that it is extremely frustrating. The world needs more advocates for this system. Just my opinion.
