Around 4-5 months back my mother started to have patches of brown colour with lumps in her legs upon getting a blood test ( in September) her
glucose fasting was- 85 mg/dl ,
hba1c- 5.5% , estimated average glucose - 111mg/dl which were normal, but her
vitamin b 12 - 78 pg/ml ( ref range- 180-914), vit D- 42.96 ( ref range- 75-250)
Can these brown patches be due to vitamin deficiency?
Or is it
diabetes and some other diabetic tests have to done?
