I am 25 male. I got checked my blood today and results in 190mg% of Rbs which is the indication of diabetes. Previously I didn't even noticed Diabetes symptoms and this is the first time I got this result. Does the following really affects my high sugar levels or I really have diabetes? 1. Didn't brushed teeth for the past 2 days 2. Didn't took enough water from the past 15 hrs and also urinated yellowish 3. Donated blood before 25 days pls confirm me.
