As a general clinical principle: Retest HbA1c no sooner than three months after commencing B12 replacement therapy, and ideally once haematological recovery has been confirmed Confirm haematological recovery normalisation of MCV and haemoglobin before interpreting the repeat HbA1c as reliable Use interim glucose monitoring such as fasting plasma glucose, OGTT, or self-monitored blood glucose (SMBG) to assess glycaemic control during the treatment period
In addition to the symptoms above, B12 deficiency may lead to the following: Muscle cramps and muscle weakness : B12 deficiency negatively impacts motor and sensory nerve function, which can cause muscle cramps and weakness (7,27)
The timeline will depend on safety data, final trial outcomes, and regulatory review
