Doctors Warn GLP-1 Users About This Overlooked Ear Condition
Sarah Ago lost 60 pounds on a GLP-1 medication. She also spent months hearing her own voice echoing inside her skull at what felt like 400 times normal volume — along with her breathing, her heartbeat, and sounds most people never notice their bodies making at all.
"It was like being in a tunnel, only able to hear my own magnified voice," the 46-year-old minister said. "You're in your own head, hearing yourself like Darth Vader."
The condition has a name: patulous Eustachian tube dysfunction, or pETD. And doctors say they're seeing it in growing numbers of patients who've lost weight rapidly on GLP-1 drugs like Ozempic, Wegovy, Mounjaro, and Zepbound.
"This used to be something we wouldn't even see once a year," said Dr. Jessica Lee, a board-certified otolaryngologist at Charleston ENT and Allergy in South Carolina. "Now it's gone up to one every other month."
What's Actually Happening
Every person has two Eustachian tubes — one on each side — connecting the middle ear to the back of the throat. Normally these tubes stay closed and open briefly to equalize pressure, like when your ears pop on an airplane. In pETD, one or both tubes stay open permanently.
The result is that sounds that are normally muffled or filtered out become overwhelming. Your own voice echoes back at you. You can hear yourself breathe. In more severe cases people can hear their own heartbeat, blood flow, neck movement — even their eyes moving in their sockets.
The connection to rapid weight loss is mechanical and specific. The Eustachian tube is surrounded by cartilage, bone, and fat. The fat pad around the tube acts as structural support, keeping it closed. When someone loses weight quickly, that fat pad shrinks — and without that cushion holding the tube shut, it stays open.
"Because the fat pad provides structural support to keep the tube shut, when it shrinks, it causes problems," said Dr. Hamid Djalilian, an ear specialist at the UC Irvine School of Medicine.
This isn't entirely new — doctors saw the same pattern when bariatric surgery became widespread decades ago. But GLP-1 drugs have brought it back at scale. A German ENT clinic documented seven pETD cases in a single year between 2024 and 2025, all in GLP-1 users who developed symptoms after four to ten months on the medication, with weight loss ranging from 8% to nearly 19% of their baseline body weight.
Why It Often Gets Missed
Part of what makes pETD frustrating is how frequently it gets misdiagnosed.
"Many patients are initially misdiagnosed with things like allergies or fluid in the ear," Lee said. "Some people, women especially, are just told it's anxiety."
Ago herself went to urgent care first, where doctors assumed she had a snorkeling-related ear infection and gave her antibiotics. Six months later she was still symptomatic. It wasn't until she saw an ENT specialist that she got an actual diagnosis.
The symptoms — echoing voice, muffled hearing, ear fullness, ringing, pressure — overlap with enough other conditions that pETD often doesn't get on a doctor's radar, particularly if the patient hasn't mentioned their recent weight loss or their GLP-1 use.
What Can Be Done
The most obvious fix — regaining weight — restores the fat pad and often resolves symptoms. But for people who've worked hard to lose weight and are seeing real health benefits, that's not a realistic option.
Conservative approaches include staying well-hydrated, using certain nasal sprays, and avoiding decongestants, which can worsen the problem by drying out the tissue further. A middle-ground intervention involves placing a small patch or piece of paper over the eardrum to dampen sound transmission. More invasive options include injectables, stents, or surgery.
Ago has had a small patch placed on her eardrum twice. She still experiences symptoms but says they've decreased dramatically — about 90% of the time she's symptom-free now. She's still on tirzepatide and says she doesn't regret taking it.
"This side effect has not been fun and has been challenging, but I think the benefits have outweighed the cost," she said.
Lee's most important advice for GLP-1 users is about pace. "There is pretty good evidence from previous studies that if you slow the rate of weight loss down, the body has more time to acclimate and you're less likely to get these symptoms." Working with a prescribing doctor to adjust the rate of weight loss — rather than pushing for the fastest possible results — may significantly reduce the risk of developing pETD in the first place.
With at least 1 in 8 American adults having tried a GLP-1, and pill versions making these drugs even more accessible, doctors expect pETD cases to keep climbing. If you're on a GLP-1 and start hearing yourself breathe, echo, or notice unusual internal sounds — it's not anxiety. It has a name, and an ENT specialist can help.
