B12 injections are also used to treat people with malabsorption (gastrointestinal conditions that prevent proper absorption of B12 from the gut), for example, people with atrophic gastritis (stomach inflammation) and intrinsic factor deficiency (pernicious anemia) or those who have undergone surgical procedures such as gastrectomy or small bowel resection (stomach or intestine removed), autoimmune diseases, etc
Many symptoms of B12 deficiency develop gradually, and patients who have experienced deficiency before often become attuned to their body's warning signs
It belongs to a class of drugs known as GLP-1 receptor agonists, which help regulate blood sugar levels and reduce appetite
B12 deficiency is a common problem for people who follow vegetarian or vegan diets, and absorption can be unpredictable
If you ever feel worse after a B12 injection, the cause is most likely not the B12 itself, but some troublesome excipient
Staying at each dose level for 6 weeks instead of 4 reduces side effects for sensitive individuals
