Dizziness on standing and the electrolyte explanation

Nausea: the most common side effect and the most dose- and titration-dependent one. It is usually most prominent in the first 24 to 48 hours after injection and attenuates as the dose is held stable. At each escalation step it often resets briefly before attenuating again.

post #2 answers the question as asked. The question underneath it is different.

Constipation: common, manageable, and frequently under-reported because it is not dramatic. Increasing fibre and fluid intake helps. Over-the-counter management is usually effective. This is worth addressing proactively rather than waiting for it to worsen.

On post #2 — agreed on the reasoning, with one qualification.

Vomiting: when it is expected (first-dose reactions or early titration) and when it is a reason to stop and seek help are different. Occasional vomiting during titration is ordinary. Persistent vomiting or vomiting of a new character later in treatment warrants contact with your clinician.

Pancreatitis: a rare but serious event with a specific presentation (epigastric pain, back pain, elevated lipase). If this constellation of findings appears, stopping the drug and seeking immediate evaluation is appropriate. Do not interpret this as "likely" — it is rare — but recognize the pattern if it appears.

Recognition and grading: nausea ranges from "noticeable" to "limiting". Constipation ranges from mild to severe. Having language to describe the magnitude helps you track whether something is worsening or stable and helps your clinician understand what you are reporting.
