Accepted answer
Week 7 is day 49: on a four-week ladder that is week 3 of dose step 2, and — at the seven-day half-life this class runs on — 7 half-lives in. Steady state is about five half-lives, so day 35 is where the concentration stops climbing on its own. Day 49 is 2 weeks past it, which means the level is no longer the variable. That distinction is most of the question: at week 3 of a step, an effect that is still accumulating is indistinguishable from one that is not resolving unless you know which side of day 35 you are on. Reflux follows delayed gastric emptying, so it tends to track meal size, meal timing and posture after eating more closely than it tracks the week number. Dose decisions are made under supervision, and nothing here is medical advice.
Answer first: the gastrointestinal effects in this class share one mechanism — slowed gastric emptying plus central signalling — and present as nausea, fullness, reflux, constipation or diarrhoea depending on the person.
Anticipating a slower-than-label titration from the start is a legitimate approach and costs only time, since the exposure ceiling is the same.
Reflux occurs because a slower-emptying stomach retains volume for longer against a lower oesophageal sphincter that has not changed. Smaller meals and not lying down within a few hours are the direct responses.
Dietary fat slowing gastric emptying is basic gastrointestinal physiology and independent of any drug effect.
Slow the titration first. It is the intervention with the best evidence and the lowest cost.
