Sleep apnoea is more than just loud snoring—it’s a serious condition that disrupts breathing during sleep, leading to fatigue, poor concentration, and even long-term health risks like heart disease and high blood pressure. One of the biggest risk factors for sleep apnoea is excess weight, but the good news is that losing weight can significantly reduce symptoms and improve overall sleep quality.
What is Sleep Apnoea?
Sleep apnoea occurs when the airway becomes blocked or collapses during sleep, causing temporary pauses in breathing. This forces the brain to wake the body up repeatedly throughout the night to restore airflow. While there are different types of sleep apnoea, obstructive sleep apnoea (OSA) is the most common and is strongly linked to excess weight.
How Excess Weight Contributes to Sleep Apnoea
Carrying extra weight, especially around the neck and upper body, can put pressure on the airway, making it more likely to collapse during sleep. Fat deposits around the throat and tongue can narrow the airways, while excess abdominal fat can reduce lung capacity, making breathing more difficult.
In addition, obesity can contribute to inflammation and fluid retention, further increasing the risk of airway obstruction. This is why people with higher body mass indexes (BMI) are at greater risk of developing sleep apnoea.
How Weight Loss Can Improve Sleep Apnoea
Losing weight doesn’t just improve overall health—it can directly help manage and, in some cases, even resolve sleep apnoea. Here’s how:
1. Reduces Fat Around the Airway
As weight decreases, the fat deposits around the neck and throat shrink, reducing airway obstruction and making it easier to breathe during sleep.
2. Decreases Inflammation
Excess weight is linked to chronic inflammation, which can contribute to airway swelling. Losing weight helps lower inflammation levels, improving airflow and reducing apnoea episodes.
3. Improves Lung Function and Oxygen Intake
Carrying excess fat around the abdomen can make it harder for the lungs to expand fully. Weight loss can ease this pressure, allowing for better breathing and increased oxygen levels.
4. Enhances CPAP Effectiveness
Many people with sleep apnoea use a CPAP (Continuous Positive Airway Pressure) machine to keep their airways open at night. Weight loss can improve the effectiveness of CPAP therapy, sometimes even reducing the need for it altogether.
Best Ways to Lose Weight for Sleep Apnoea Relief
If you’re looking to manage sleep apnoea through weight loss, here are some effective strategies:
- Increase Protein Intake: A high-protein diet helps preserve muscle while promoting fat loss. Meal replacements like Formulite shakes and bars provide a convenient way to get balanced nutrition without excess calories.
- Focus on Whole Foods: Prioritise lean proteins, vegetables, healthy fats, and whole grains while reducing processed foods and refined sugars.
- Stay Active: Regular exercise, even moderate activities like walking, can support weight loss and improve sleep quality.
- Limit Alcohol and Smoking: Both alcohol and smoking can worsen sleep apnoea by relaxing the airway muscles and causing inflammation.
- Maintain a Regular Sleep Schedule: Good sleep hygiene can help improve sleep quality and support weight management.
Final Thoughts
Weight loss is not a guaranteed cure for sleep apnoea, but for many people, it can significantly reduce symptoms and improve sleep quality. Even a small amount of weight loss—5 to 10% of body weight—can make a big difference. If you struggle with sleep apnoea and excess weight, making healthy lifestyle changes could be the key to better sleep and overall well-being.
