Testimonials

"I came to Nithra Institute of Sleep Sciences with complaints of excessive daytime sleepiness and a history of diabetes and hypertension for more than a decade. I try to stay active, eat healthily, and take my vitamins, and yet every day was a battle against fatigue and sleepiness. I was finding it too difficult to manage. I want to take this opportunity to express my heartfelt thanks and appreciation to Dr N Ramakrishnan and his team for the kind of service and genuine attention that I received during my evaluation. A sleep study was promptly scheduled, the sleep lab was comfortable, and the staff were courteous. The Sleep Specialist interpreted my results and advised me to start CPAP (Continuous Positive Airway Pressure) therapy. After using CPAP, I felt comfortable and refreshed. I was no more falling asleep during the day!"

"For a long time, I have faced trouble in getting a good night's sleep. I was tossing and turning all night long, waking up in the middle of the night and not getting back to sleep. Because of this, I had a severe headache that impacted my performance at work. While searching for a solution on the internet, I came across the Nithra website, where details of sleep-related problems were mentioned. Knowing the aspects, I realized that I had to meet a Sleep Specialist. I took an appointment for a consultation. I filled out a questionnaire; was advised to do a sleep study to diagnose the severity of the apnea. I was diagnosed with severe obstructive sleep apnea from my test results and was recommended to use CPAP. Knowing the seriousness of my apnea, I have started to use CPAP without any hesitation. I feel great, waking up in the morning when the alarm is going off the first time. I have more energy and seem to be thinking clearly."
