My bloodwork came back abnormal and now i have to see an endocrinologist. what could be the problem?

Many reasons: An endocrinologist takes care of diabetes (blood sugar), lipids (cholesterol), thyroid, adrenal, pituitary, parathyroid (calcium), and reproductive hormones. Many of these items may be found or suggested on routine bloodwork. Ask your doctor what it was in the blood work that made him make the referral. You should probably follow through and see the endocrinologist.
