Please share the actual
B12 value and the lab report; treatment depends on the severity and cause of deficiency.
A 1000 mcg B12 injection is commonly used for marked deficiency or malabsorption, but the schedule should be confirmed by a doctor rather than repeated on your own.
Vitamin D 60,000 IU every 2 weeks should also follow the measured level and
calcium/
kidney status.
Please consult or book on Practo with the report so I can tailor the plan.
Next Steps
Check CBC, folate,
ferritin,
thyroid and renal profile as appropriate; also review diet, gastritis, metformin or acid-suppressant use.
