Comment VITAMINS and I’ll send you the full PDF.
Your diabetic patient has numbness in both feet. You document “diabetic neuropathy” and move on.
Check the B12 first.
Metformin is one of the most missed causes of B12 deficiency — on the ward and in Part 1 stems.
Two more you prescribe every day:
Long-term PPIs → B12 and magnesium
Isoniazid → B6 (this is why we co-prescribe pyridoxine)
The list is longer than three. We’ve put every drug that causes a vitamin deficiency on one page — comment VITAMINS below and it lands in your DMs.
Follow .medicos so the DM doesn’t go to your Requests folder.
