Why Am I So Tired? Understanding Sleep Apnoea in Women

Many women are told they are tired because of stress, hormones, anxiety, or simply doing too much. While all of those things can contribute to fatigue, there is one condition that is consistently overlooked in women — obstructive sleep apnoea.

Sleep apnoea is often thought of as a condition affecting overweight middle-aged men who snore loudly. The reality is quite different. Women develop sleep apnoea too, and when they do, it frequently looks nothing like the textbook picture.

What is Obstructive Sleep Apneoa?

Obstructive sleep apnoea (OSA) occurs when the muscles of the throat relax during sleep, causing the airway to narrow or close. Breathing stops briefly, sometimes hundreds of times a night, and the brain partially wakes to restore normal breathing. Most people have no memory of this happening.

The result is fragmented, unrefreshing sleep, even after a full eight hours in bed.

How does it present differently in women?

In men, OSA typically presents with loud snoring and witnessed breathing pauses, symptoms a partner is likely to notice. In women, the picture is often subtler. Common symptoms include:

• Persistent fatigue or exhaustion that doesn't improve with rest

• Waking with headaches, particularly in the morning

• Difficulty concentrating or brain fog

• Low mood, irritability, or symptoms resembling anxiety or depression

• Insomnia or restless sleep

• Frequent waking through the night

Because these symptoms overlap with so many other conditions such as thyroid disorders, iron deficiency, perimenopause, depression, OSA is often the last thing investigated. Research suggests women with OSA wait significantly longer for a diagnosis than men.

Why does it matter?

Untreated OSA places considerable strain on the cardiovascular system. It is associated with high blood pressure, increased risk of heart disease and stroke, diabetes, and impaired immune function. Beyond the physical risks, the cognitive and emotional burden of chronic poor sleep affects every aspect of daily life.

What can be done?

The good news is that OSA is very treatable. At Perth Oral Medicine and Dental Sleep Centre, we offer oral appliance therapy as an effective, comfortable alternative to CPAP, particularly well-suited for mild to moderate OSA, or those who have struggled to tolerate a CPAP mask.

Using the latest intraoral scanning technology, each appliance is custom-designed for your mouth, 3D printed for precision fit, and calibrated to gently hold the airway open during sleep.

When should you seek help?

If you are waking unrefreshed, feeling exhausted despite adequate sleep, or experiencing any of the symptoms described above, it is worth raising OSA with your GP or dentist. A referral to our practice is all you need to get started.

You deserve restorative sleep. It is not a luxury, it is a foundation of good health.
