About us ashansiam March 4, 2022

Suwa Ninda is an educational website for the general public on healthy sleep and sleep disorders with an emphasis on sleep related breathing disorders. This website is developed by the Sleep Assembly of the Sri Lanka College of Pulmonologists.

This website mainly addresses the commonest cause of sleep disordered breathing which is obstructive sleep apnoea (OSA). Each section has a video narration giving an outline of the content for those who prefer to “watch” than “read”. There are interactive tools to determine the ideal bedtime, how sleepy a person is and to calculate the risk of OSA.

A key area in the diagnosis and management of OSA is the upper airway assessment and upper airway surgery. This is done by the ENT surgeons. (Consultant Otorhinolaryngologists and Head and Neck Surgeons). The content area pertaining to these sections were developed by the College of Otorhinolaryngology and Head and Neck surgeons.

In addition to OSA this website also gives an overview of the neurological diseases associated with sleep. These conditions are managed by our colleagues in neurology. We partnered with the Association of Sri Lankan Neurologists for the development of this content.

Obstructive sleep apnea (OSA) is the main sleep related breathing disorder seen worldwide affecting almost 1 billion of the population. In Sri Lanka 16.8 % of the population are at risk of having OSA. As respiratory physicians we see OSA frequently in our practice and sadly on most occasions patients come to us after developing OSA related complications such as a heart attack or a stroke and sometimes even after road traffic accident as a consequence of falling asleep at the wheel. Early recognition and treatment can prevent these complications. As such there is a dire need to educate the public on OSA. There are respiratory physicians in state sector hospitals across the country and most of the state sector hospitals have facilities to investigate for sleep related disorders; OSA can be easily diagnosed and treated. There is a lot that can be done.
The development of a webpage for the general public, was the brain child of Dr Amitha Fernando, Senior Consultant Respiratory Physician and a member of the sleep assembly. The webpage is written in an easy-to-understand simple language avoiding medical terms as much as possible. It is available in Sinhala, Tamil and English.
I sincerely hope “suwa ninda” webpage will pave the way to creating awareness on sleep disorders amongst the public.
