Other reactions warranting urgent GP contact include: Unexplained muscle weakness or cramping Persistent vomiting or severe abdominal pain Signs of hypokalaemia (low potassium) during initial treatmentmuscle weakness, irregular heartbeat, or severe fatigue In patients with severe, longstanding B12 deficiency, rapid correction can occasionally precipitate hypokalaemia as new red blood cells are produced, consuming available potassium
For example, those with severe B12 deficiency or nerve damage might need more
Moreover, those who combine diet with intense physical activity or high-output cardio may experience increased fatigue if B12 levels are not optimal
At comparable timepoints, tirzepatide showed 3-5 percentage points greater weight loss across dose ranges
Surprisingly Institutions such as the Cleveland Clinic, the NIH, amongst others appear to be totally obvious to this
