GLP-1 Medications, Sleep Apnea & Oral Health

GLP-1 Weight Loss Medications and Sleep Apnea: What Patients Need to Know

More and more patients are taking GLP-1 weight loss medications such as Ozempic®, Wegovy®, Rybelsus®, Mounjaro®, and Zepbound® to help manage diabetes or lose weight.

While these medications can be very effective, many people are unaware that they may also affect sleep, breathing, reflux, and oral health — especially in patients with snoring or obstructive sleep apnea (OSA).

How GLP-1 Medications Can Affect Sleep and Breathing

GLP-1 medications slow how quickly the stomach empties. This can increase acid reflux, particularly at night when you’re lying down.

For people who snore or have sleep apnea, this combination may quietly increase the risk of:

• Nighttime acid reflux
• Gasping or choking during sleep
• Mouth breathing and dry mouth
• Inflammation of the airway
• Cough, hoarseness, or asthma-like symptoms

Many patients don’t realize these symptoms may be connected to their new medication.

 

The Hidden Link Between Sleep Apnea and Acid Reflux

Sleep Apnea Can Make Reflux Worse

During sleep apnea events, your body creates strong pressure trying to breathe. This pressure can pull stomach acid upward, making nighttime reflux more likely.

Nasal Congestion Increases Mouth Breathing

If your nose is congested, you may breathe through your mouth at night. Mouth breathing increases dryness and makes it easier for stomach acid or contents to reach the throat and airway.

Micro-Aspiration: A Silent Problem

Tiny amounts of stomach contents can enter the airway during sleep without obvious symptoms. Over time, this may cause:

• Chronic cough
• Frequent throat clearing
• Hoarse voice
• Wheezing or breathing discomfort

 

Why Your Dentist Cares About Your Sleep and Medications

Your dentist may notice signs of sleep apnea, reflux, or dry mouth before you do. Dental changes linked to these conditions include:

• Tooth enamel erosion
• Increased cavities, especially near the gumline
• Tooth sensitivity
• Jaw clenching or grinding (bruxism)
• Dry mouth (xerostomia)
• Mouth soreness or fungal infections

Dentistry isn’t just about teeth — it’s also about airway health and sleep safety.

 

Common Symptoms to Watch For If You’re Taking GLP-1 Medications

If you’ve started a GLP-1 medication and notice any of the following, it’s worth mentioning to your dentist or doctor:

• Increased heartburn or nausea
• Dry mouth or waking up thirsty
• More snoring or mouth breathing
• Chronic cough or hoarse voice
• Jaw soreness or cracked teeth
• Poor sleep or frequent awakenings

 

Protecting Your Teeth and Mouth

If You Have Acid Reflux or Vomiting:

• Do not brush immediately afterward
• Rinse with water mixed with a little baking soda
• Wait 30 minutes before brushing
• Ask about high-fluoride toothpaste to protect enamel

If You Have Dry Mouth:

• Stay well hydrated
• Use xylitol lozenges or gum
• Ask about prescription-strength fluoride if you’re at high cavity risk

 

The Bottom Line

GLP-1 medications can be life-changing for weight loss and diabetes — but they may also affect sleep apnea, reflux, breathing, and oral health.

If you snore, have sleep apnea, or notice new dental or breathing symptoms after starting a GLP-1 medication, your dental team can help identify problems early and guide you toward safer, more restful sleep.
