Nausea often appears around a new start, a dose increase, or the first 24-72 hours after a shot because GLP-1 medicines slow gastric emptying and change appetite signals. The useful move is not to guess from memory: track shot timing, meal size, hydration, and whether nausea is improving or escalating.
Search answers should end in a record, not another vague article.
Shot date, medication, dose, and whether this was a step-up week
Nausea severity, start time, duration, and vomiting status
Meal size, food texture, fluids, protein, sleep, and reflux/burping context
Whether symptoms repeat at 24, 48, or 72 hours after each shot
Contact a clinician or urgent care for severe, persistent, rapidly worsening symptoms, inability to keep fluids down, severe abdominal pain, fainting, or other concerning changes.
