If I have grave's disease am I more at risk of getting diabetes or other endo disorder?

Mild increased risk. Graves' disease is an autoimmune condition, in which the immune system makes antibodies that target one's own proteins. Having one autoimmune condition does increase the risk of developing another, including type 1 diabetes, or addison's disease (hypoadrenalism) by about 10-20% compared to someone with no known autoimmune disorders.
Yes. Autoimmune thyroid disease of which graves is part of them increases your chances of developing type i diabetes (autoimmune destruction of cells that produce insulin) and addisons disease (adrenal insuficiency due to developed autoimmunity to the adrenal glands.
