Why Has My Snoring Suddenly Become Worse?

Snoring that was previously manageable - or barely noticeable - can change quite abruptly. Partners are often the first to raise the alarm, reporting that snoring has become louder, more consistent, or accompanied by new sounds like gasping or choking that weren't there before. When snoring suddenly worsens, there is almost always a trigger, and identifying it is the first step toward doing something about it.

Common Reasons Snoring Gets Suddenly Worse

Weight gain is one of the most common culprits. Even modest weight gain - particularly around the neck, jaw, and throat - increases the volume of soft tissue surrounding the upper airway, narrowing the space available for airflow during sleep. The effect on snoring can be disproportionate to the amount of weight involved, particularly in people who were already borderline snorers.

Alcohol and sedatives are powerful airway relaxants. If you have recently started drinking more frequently before bed or have introduced a new medication that acts on the central nervous system, this alone can transform an occasional snorer into a habitual one. Even a single standard drink consumed within a few hours of bedtime measurably increases airway collapsibility and snoring severity.

Nasal congestion from a cold, flu, sinus infection, or seasonal allergy flare-up forces mouth breathing during sleep, significantly worsening both snoring severity and airway stability. If the sudden worsening has coincided with a respiratory illness or a change in season, nasal obstruction may be the primary driver.

Ageing produces a gradual but real decline in the muscle tone of the throat and airway. For some people, this process reaches a tipping point and snoring that was previously occasional becomes consistent. This can happen without any obvious external trigger, and often comes as a surprise.

Hormonal Changes in Women

Hormonal shifts are a significant and frequently underappreciated cause of worsening snoring in women. Perimenopause, menopause, and pregnancy all produce hormonal changes that affect upper airway muscle tone and the propensity of the airway to collapse during sleep. Women who previously snored only occasionally often find that snoring becomes far more regular and disruptive during these periods. The decline in oestrogen and progesterone associated with menopause is particularly significant, as these hormones play a protective role in maintaining airway muscle tone during sleep.

When Worsening Snoring Signals Something More Serious

A noticeable and sustained increase in snoring warrants proper assessment, particularly if it is accompanied by any of the following: waking unrefreshed despite adequate sleep time, excessive daytime tiredness or difficulty concentrating, morning headaches, a partner reporting pauses in breathing or witnessed gasping during sleep, or a general sense that sleep quality has declined. These symptoms together paint a picture of possible new or worsening obstructive sleep apnoea - a condition in which the airway repeatedly collapses during sleep, with real and accumulating health consequences if left untreated.

Sleep apnoea is significantly underdiagnosed in Australia, and a sudden worsening of snoring is one of the most common presentations that prompts diagnosis. The good news is that once identified, it is very treatable and a custom mandibular advancement splint offers a comfortable, effective option for the majority of patients.
