dosage b12 injection and Frequency: 7 Guidelines for Adults Vitamin B12 Injections (Cyanocobalamin Injections)

Felzartamab (from I-Mab), already approved for treating membranous nephropathy, is undergoing trials for additional diseases

While B12 can be found in foods like meat, fish, and dairy, some people struggle to absorb enough through diet alone

As discussed, GLP-1 therapy creates a real risk of B12 depletion over time

Additional at-risk groups include: Vegans and strict vegetarians , who may have low dietary B12 intake People with autoimmune conditions , including pernicious anaemia or type 1 diabetes Individuals with gastrointestinal conditions such as Crohn's disease or coeliac disease, which impair nutrient absorption People who have undergone bariatric surgery , which can significantly reduce B12 absorption Long-term users of proton pump inhibitors (PPIs) or H2-receptor antagonists , which reduce gastric acid and impair B12 release from food Those with a family history of either pernicious anaemia or diabetes For these groups, simultaneous monitoring of B12 status and glycaemic markers is particularly important to avoid diagnostic errors

Consequently, it is hoped that in the near future, individualized pharmacological management of obesity could be meaningfully achieved by targeting different pathways governing energy homeostasis and weight regulation
