Following a positive diagnosis of laryngopharyngeal reflux (LPR), typical treatments are medication, diet changes and lifestyle tweaks or surgery.

The REZA BAND is one of the first non-medicinal, non-surgical devices designed to reduce symptoms associated with laryngopharyngeal reflux (LPR) – also known as silent reflux – including chronic throat irritation and cough, hoarseness, difficulty swallowing and post nasal drip.

What is the REZA BAND?
The REZA BAND is a device that is worn around the neck while you sleep. The band aims to stop the regurgitation of stomach contents from passing through the upper oesophageal sphincter (UES) – the muscle at the top of your oesophagus that opens when you swallow and should otherwise remain closed – by adding a small amount of pressure (between 20-30 mmHg) on the UES.

What happens when I breathe or swallow?
According to the manufacturer Somna Therapeutics, using the REZA BAND feels like wearing a shirt collar buttoned with no effect on breathing or swallowing.

How is it fitted?
The REZA BAND is positioned around your neck with cushions positioned over the cricoid cartilage area. A Comfort Dial allows you to slightly adjust the REZA BAND for comfort.

How much does it cost?
The REZA BAND is available in the US for $299 (£194) and must be prescribed by your doctor to ensure it fits properly and is comfortable. In the UK it is expected to be available via GDS Medtech.

How effective is it?
According to studies, the REZA BAND can significantly reduce the symptoms of LPR within the first two weeks of use. 85 per cent of people studied experienced greater than 25 per cent improvement in their symptoms, with the average improvement being 54 per cent.

Are there any associated problems?
Problems such as skin irritation, pain and choking have been reported by a tiny minority but these symptoms were generally mild and short in duration. According to research, there has been no effect on heart rate, blood pressure or cardiac rhythm either when the band is placed as intended over the cricoid cartilage, or when it is laterally displaced, over the jugular and carotid vasculature.
