These include: swollen face, tongue, and throat difficulty swallowing difficulty breathing While B12 is fairly safe on its own, it doesnt always play well with certain drugs or supplements
Below is a clinicians view of who actually needs B12 injections, how often, what the NHS will and will not do for you, and what we check before we book the first shot
elevated triglycerides (defined as 150 mg/dL), decreased High Density Lipoprotein (HDL) (ranges below 40 mg/dL in men and 50 mg/dL in women), elevated blood pressure (defined as systolic blood pressure above 130 mmHg or diastolic blood pressure above 85 mmHg) and elevated fasting glucose (defined as blood glucose above 100 mg/dL)
This can actually help prevent the gaunt look sometimes associated with rapid weight loss
If you are making a subcutaneous injection just under your skin, pinch the area where you will be taking the shot
