Not pregnant obgyn lab work requests

Is it weird my obgyn requested lab work to be done such as, 12 hour fasting glucose, cholesterol, vitamin d levels? I'm not pregnant, I went to have my iud removed and overdue pap done. When I told my sister and mom my ob requested labs to be done they were confused as to why and acted weird. I didn't think it was weird but idk lol. A little back information, I had pre-eclampsia 2 years ago during my pregnancy I went from 132-208 lbs and delivered early. I lost all my weight gained during pregnancy took about 16 months but over winter I gained some back so I'm at 156 now. My family thinks my doctor was in directly telling me I'm over weight ?! I do gain weight very quick though.. I'm 27 years old. Has any one else had their obgyn request these labs while not being pregnant ? Shouldn't my primary be the one requesting if concerned? Thanks for reading !
