Blood glucose level is a function of food intake and blood hormone levels. Insulin and glucagon are two key hormone that regulate the glucose levels in blood. Medications used to treat diabetes may alter blood glucose levels and lower them. Fluctuating glucose levels in diabetes patients warrant a doctor visit to titrate the dose or medications, as applicable. The kidney functions need to be measured as declining renal functions is known to cause impaired insulin levels and hence, similar fluctuations.
