When I talk to my patients about their health, sleep often comes up. But there is a specific conversation I find myself having over and over again, particularly with my female patients. They come to me feeling exhausted, foggy, and frustrated. They have been to other doctors. They have been told they are stressed. They have been told they are depressed. They have been told it is just part of getting older.
Rarely have they been told they might have sleep apnea.
For decades, Obstructive Sleep Apnea (OSA) was considered a “man’s disease.” We have all seen the caricature: an older, overweight man who snores loud enough to rattle the windows. But as a healthcare provider, I am here to tell you that this stereotype is dangerous. It leaves millions of women suffering in silence. Sleep apnea in women looks different, sounds different, and feels different. And because the symptoms are often subtler, they are incredibly easy to ignore or misdiagnose.
In this guide, I want to walk you through the signs that women often overlook. If you have been struggling with your energy and mood, this might be the missing piece of the puzzle you have been looking for.
The Gender Gap in Sleep Health
Before we dive into the specific symptoms, it is important to understand why this is happening. Women are biologically different from men, and that includes how our airways function and how our bodies react to a lack of oxygen. While men typically experience what we call “apneas” (complete blockages of the airway), women are more likely to experience “hypopneas” or “RERAs” (Respiratory Effort-Related Arousals).
This means you might not stop breathing completely. Instead, your breathing becomes very shallow and requires a lot of work. Your brain realizes you are struggling and wakes you up just enough to take a better breath. You might not remember waking up, but this struggle pulls you out of deep, restorative sleep all night long. Because you aren’t gasping for air in the dramatic way men often do, your partner might not notice anything wrong, and neither do you.
This leads to a staggering statistic regarding sleep apnea in women.
Data Point: According to the American Academy of Sleep Medicine, it is estimated that nearly 90% of women who have sleep apnea have not been diagnosed. That means the vast majority of women with this condition are walking around untreated, wondering why they feel so terrible.
Symptom 1: Insomnia and “Wired” Fatigue
If you ask a man with sleep apnea how he sleeps, he will often say, “I sleep great, but I’m tired.” He hits the pillow and is out like a light. Women are different. In my practice, I find that women with sleep apnea often complain about insomnia.
You might have trouble falling asleep because your body is in a state of low-level “fight or flight” anxiety about breathing. Or, more commonly, you have trouble staying asleep. You might wake up at 2:00 AM and 4:00 AM and stare at the ceiling. Because you woke up, you assume you have insomnia. However, the reality is often that an apnea event (a pause in breathing) woke you up, and now your brain is too alert to drift back off.
This creates a sensation of being “tired but wired.” You are exhausted, but your body won’t let you rest. It is a cruel cycle, and it is rarely the first thing doctors think of when they hear “insomnia.”
Symptom 2: Morning Headaches
Do you wake up reaching for the ibuprofen? Morning headaches are a classic sign of sleep apnea, yet many women attribute them to clenching their jaw, sleeping in a bad position, or stress.
When you have sleep apnea in women, your oxygen levels drop repeatedly throughout the night. At the same time, carbon dioxide builds up in your blood because you aren’t exhaling fully. This leads to the dilation of blood vessels in the brain, which causes a throbbing headache when you wake up. These headaches usually go away within an hour or two of waking up as you breathe normally and get oxygen back into your system.
If you are waking up with a dull ache effectively every morning, your body is trying to tell you that it was starving for air during the night.
Symptom 3: Anxiety and Mood Changes
This is perhaps the most heartbreaking symptom because it leads to so many misdiagnoses. When a woman goes to her general practitioner complaining of fatigue, irritability, and trouble sleeping, she is very often walked out with a prescription for antidepressants or anti-anxiety medication.
While depression and anxiety are real and serious conditions, they are also symptoms of chronic sleep deprivation. When you have sleep apnea, your sleep is fragmented. You miss out on REM sleep, which is the stage of sleep where we process emotions and regulate our mood. Without it, we become emotionally fragile.
I have seen patients who were convinced they had developed an anxiety disorder, only to find that their anxiety significantly decreased once we treated their airway issues. When your body fights for breath all night, it releases stress hormones like cortisol. You wake up with a body full of stress chemicals, so naturally, you feel anxious.
Symptom 4: The “Silent” Snorer
We need to talk about snoring. Yes, many women with sleep apnea snore. However, it often doesn’t sound like the buzz-saw snoring we associate with men. For many of my female patients, the sound is more subtle. It might be a heavy breathing sound, a soft purring, or occasional light gasping.
Many women are embarrassed to admit they snore, or they simply don’t believe they do. “I’m a lady, I don’t snore,” is a phrase I hear often. But snoring is simply the sound of air vibrating against collapsed tissue. It is a mechanical issue, not a character flaw. Even if you don’t snore loudly, silence doesn’t mean safety. As I mentioned earlier, women often have silent pauses in breathing that are just as disruptive as loud snoring.
Symptom 5: Frequent Trips to the Bathroom
This symptom surprises almost everyone. It is called nocturia. If you are waking up two, three, or four times a night to use the restroom, you probably blame a small bladder or maybe aging.
Here is what is actually happening: When your breathing is obstructed, the pressure in your chest cavity changes. This signals your heart that it is working too hard. In response, your heart releases a protein that signals your kidneys to dump fluid to lower the pressure. The result? You suddenly have a full bladder.
If you treat the sleep apnea, the urge to go to the bathroom in the middle of the night often disappears or reduces significantly. It wasn’t a bladder problem; it was a breathing problem.
The Hormonal Connection: Menopause and Pregnancy
We cannot discuss sleep apnea in women without discussing hormones. Hormones play a massive role in the tone of our muscles, including the muscles that keep our throat open while we sleep.
Progesterone and estrogen act as protective agents for the airway. They help keep the muscles toned and the airway patent (open). This is why younger women have lower rates of sleep apnea than younger men. However, this protection doesn’t last forever. During perimenopause and menopause, these hormone levels drop drastically.
Data Point: Research indicates that post-menopausal women are three times more likely to have moderate to severe sleep apnea compared to pre-menopausal women. The risk effectively catches up to that of men once the protective hormones decrease.
Many women assume that their sleep issues during menopause are just hot flashes. While hot flashes are certainly disruptive, they often mask the development of sleep apnea. If you are going through menopause and your sleep quality has plummeted, it is worth looking beyond the hormones.
The Consequence of Ignoring Symptoms
I want to keep this positive because there is a solution, but I also need to be real with you about the risks. Ignoring these symptoms isn’t just about feeling tired. Sleep apnea is a serious inflammatory condition.
When untreated, sleep apnea in women is linked to:
- Heart Health Issues: High blood pressure and irregular heartbeats (arrhythmias) are common.
- Weight Gain: Sleep deprivation messes with your hunger hormones (ghrelin and leptin), making it chemically difficult to lose weight.
- Diabetes Risk: Poor sleep affects how your body processes glucose.
- Cognitive Decline: Chronic lack of oxygen can lead to memory loss and difficulties with focus.

Diagnosis and Treatment: It’s Not Just CPAP
Now for the good news. If you recognize yourself in these symptoms, you can get better. The first step is a diagnosis. The days of needing to sleep in a cold, clinical lab with wires glued to your head are largely behind us. Home sleep tests are now very common, affordable, and accurate for most people. You can take the device home, sleep in your own bed, and bring it back.
Once diagnosed, many women fear the CPAP machine—the mask and hose. While CPAP is the “gold standard” and a lifesaver for many, it is not the only option. Especially for mild to moderate sleep apnea, which is very common in women, oral appliance therapy is a fantastic alternative.
As a specialist in this field, I fit many patients with a custom-made dental device. It looks a bit like a sports mouthguard or a retainer. It gently positions your jaw forward just a few millimeters. This prevents the tongue from collapsing backward and keeps the airway open. It is silent, portable, and requires no electricity. For many of my female patients, this is the preferred solution.
Taking Back Your Vitality
I hope this article has shed some light on why you might be feeling the way you do. If you are exhausted, anxious, or suffering from morning headaches, please do not accept “it’s just stress” as the final answer. You know your body better than anyone else. If something feels off, it probably is.
Sleep apnea in women is treatable. I have seen countless patients transform their lives simply by getting oxygen back into their systems at night. The color returns to their face, the sparkle comes back to their eyes, and they have the energy to enjoy their lives again.
You deserve to wake up feeling refreshed. You deserve to have energy for your family, your career, and your passions. Do not ignore the signs. Talk to a sleep specialist or a dentist qualified in sleep medicine today. It might just be the most important appointment you make this year.
