Tirz and sleep apnea

Summary

Does tirzepatide improve sleep apnea and can users stop using CPAP after weight loss on these meds?

Users report that weight loss from reta or tirz reduces snoring and apnea events for many, with some ditching CPAP entirely after 20-125 lbs lost while others see only partial improvement or none. Tirz has specific approval for OSA in obese adults but participants attribute benefits mainly to fat reduction around the airway rather than a direct drug effect. Dosing discussions focus on staying low if loss continues instead of escalating per standard schedules.

What this discussion establishesWhere people disagree

Whether the medications provide any direct benefit to sleep apnea beyond the weight they help users lose

Still open

How much additional weight loss is required for any given person to fully eliminate the need for CPAP

Nothing here is advice.

Hello everyone. On my fourth dose of reta today at 1mg and planning to raise it to 1.5 or 2mg next week. Results so far are solid with 12 pounds gone in three weeks, which feels great. Reading about tirz and sleep apnea caught my interest. I deal with SA and keep pulling the CPAP off while asleep no matter how hard I try. For others who have SA, how well has tirz worked and what is the best way to add it in. I am considering reta on Monday morning and tirz on Wednesday evening. Does that plan make sense and what amount would help?

I cannot comment on tirz but I can on reta. After a month the weight loss was notable and snoring stopped completely at night. No new sleep studies have been done yet but rest is much better without constant waking from snoring. It is unclear if the medication itself helps directly or if the weight reduction is doing most of the work. Either way the improvement is credited to reta.

Not enough weight has come off yet to judge whether snoring has changed and my partner has not noticed anything either. Falling asleep has been harder since starting reta so magnesium and cherry extract are being used for that. Still, mornings feel less exhausted than before. The tirz and SA reports are interesting.

Apnea is also an issue here and the studies were read. The main factor seems to be the weight reduction itself, with no real difference between tirz or reta.

A quick search showed that tirzepatide is the first medication approved specifically for moderate to severe obstructive sleep apnea in adults with obesity. Weight loss remains the biggest driver in lowering SA.

The CPAP community is fairly quiet yet helpful when questions come up. A durable medical provider can assist in locating a mask that fits comfortably. Adjusting to it takes time.

Twenty pounds came off with reta and the C-PAP was no longer needed. The specific medication does not seem to matter as much as shedding the weight around the neck and upper airway. Tirz is often chosen for SA because of its approval status for that use in weight loss, though the approval may have been influenced by other factors.

If it works the details do not matter much.

Every mask option from the health service has been tried and they all get fought off during sleep.

The medication was prescribed for sleep apnea. When brand pricing did not work out a smaller pharmacy option was used at first. Later other sources became known. Events per hour on the machine have dropped a lot after 35 pounds lost. The doctor thinks the machine might be unnecessary once goal weight is reached.

After losing 125 pounds sleep apnea was thought to be gone and the CPAP seemed to be interfering with rest, so the pulmonologist's assistant was asked about stopping it. That was tried two months ago. Sleep remains poor and peptides have been blamed, yet a recent sleep study confirmed apnea is still present.

It probably does not disappear once present. That is unfortunate but seems to be how it goes.

Keep going. Hope the machine can be left behind.

Thanks. The target weight has been adjusted and another attempt will be made. Starting weight was 335 and reached 210 recently, but sub-200 may be needed to stop using the machine. Good luck with your own effort.

Any weight reduction should help. Sleep actually got worse on reta along with heart rate changes that prompted a return to mostly tirz. The CPAP remains difficult to tolerate at night despite using a favored mask. It gets used during computer time instead because it helps shift into a calmer state. A septoplasty was done recently and a special side-sleeping pillow was ordered from overseas. It is a long process.

Over 100 pounds lost yet OSA continues because of a naturally small airway. A recent test still showed nearly 50 episodes an hour. The same issue appears in a child so testing is being considered. Hoped tirz would resolve it but that has not happened. A particular pillows-style mask works well for sleep on most nights.

We seem to share some history including gastric bypass. Recent study shows AHI at 9, improved from 35 before the medication. Still not resolved and an airway factor may be involved. A full-face mask is used because mouth breathing prevents pillows style. Taping the mouth once caused a panic attack so that was stopped. More loss and another study are planned.

You are planning to raise the dose next week while still losing. Some follow trial schedules even when loss is happening. If weight keeps dropping there may be no need to increase until a four-week plateau occurs. Rushing the dose is common.

WarmWillow43archiveJul 28

Three to four pounds weekly is a solid pace. The body has a daily limit on how many calories can come from fat stores and that rate is near the top end.

IronHarbour83archiveJul 28

That is worth considering. Loss will be tracked over the next two weeks to decide next steps.

IronHarbour83archiveJul 28
↳ replying to @SlowAnchor55

True, the standard approach was being followed without question. Loss will be watched for a few weeks to check for a plateau before any increase.

WarmWillow43archiveJul 28

If progress continues there is no reason to change. With a roughly five-day half-life it takes about four weeks for levels to build up fully. A 2.5 mg dose would reach nearly 4 mg accumulation by then.

SteadyKettle52archiveJul 29

Initial sleep study showed 115 events per hour about a year ago. Average is now one event per hour with the machine. Tirz has been used with substantial weight loss since then. Snoring occurred even when younger and fit so CPAP will likely be needed at goal weight. The doctor noted that weight loss does not always eliminate sleep apnea.
