Amylase and Lipase in Acute Pancreatitis
Test Rise Peak Return to baseline Lipase 4-6 hours 48 8-14 days Amylase 2-4 hours 24-48 5-7 days Serum lipase elevation has a better diagnostic value as compared to serum amylase due to its superior specificity. Amylase has a low molecular weight and as a result can easily pass through…

How Metformin Causes Vitamin B12 deficiency?
Multiple studies have shown that metformin reduces serum B12 levels in 10–30% of patients. The effect increases with the duration of the therapy. Decrease in vitamin B12 absorption and levels following metformin use typically starts as early as the 4th month. Mechanisms of Vitamin B12 deficiency with Metformin Use: It…
