Aetna Wegovy coverage — new criteria effective June 2026

Taking the question as asked, rather than the general version of it. The mechanism that matters here is not stomach emptying, it is central. GLP-1 receptor agonism in the arcuate nucleus stimulates POMC neurons and suppresses AgRP/NPY signalling, which is why the effect is appetite and food salience rather than physical fullness. Delayed gastric emptying largely tachyphylaxes over the first months; the appetite effect does not.

Happy to go further on any of that.

That holds for the injectable. The oral formulation has different absorption behaviour and the dose numbers are not interchangeable, which is worth saying out loud because people quote them as if they were.

The list price and the price I actually pay differ by a factor of six depending on which of four routes I use, and none of that is transparent from…

All true, with one condition: that curve is for people who reached the dose on schedule. Anyone who slowed the ladder for tolerability is on a different, flatter curve, and comparing yourself with the published mean will make you feel like a non-responder when you are not.

That is the short version; the long version is somebody else's post.

Clinical perspective, offered as context rather than as advice.

...regarding the discontinuation data for cost and coverage...

I want to reframe the discontinuation narrative. We don't say "insulin fails because blood sugar rises when you stop it." We don't say "antihypertensives fail because BP goes up without them."

Why do we apply different logic to anti-obesity medications? The answer is stigma. We still, unconsciously, believe obesity is about willpower rather than biology. The discontinuation data actually PROVES it's a chronic biological condition requiring ongoing treatment.

This reframing isn't semantic — it has implications for insurance coverage, treatment duration, and patient expectations.
