Dr. Preeti Devnani, MD
Sleep Medicine Specialist & Health Science Writer
Dr. Preeti Devnani is a Sleep Medicine Specialist at Cleveland Clinic, where she practices within one of the world's most respected academic medical institutions. She holds triple board certification from the American Board of Psychiatry & Neurology in Neurology (2003), Sleep Medicine (2011), and Clinical Neurophysiology (2019) — a combination of credentials that reflects both the breadth and depth of her expertise in sleep-disordered breathing, brain function, and neurological sleep conditions. She completed her medical education at Dr DY Patil Medical College, Mumbai, and her residency and fellowship training at Loyola Medical Center, bringing both an Indian clinical foundation and a rigorous North American academic formation to her practice.
Dr. Devnani's clinical focus encompasses the full range of sleep disorders, with particular expertise in obstructive sleep apnea, snoring, insomnia, and parasomnias in adult patients. Her neurophysiology training gives her a distinctive perspective on how sleep disorders manifest at the level of brain activity — including how EEG patterns, arousal thresholds, and cortical dysregulation interact with airway mechanics to produce the clinical picture seen in snoring and OSA patients. She is affiliated with the Association of Sleep Sciences and Medicine (ASSM) and is active in international sleep medicine education.
For Snorple, Dr. Devnani contributes content grounded in current sleep medicine evidence — covering topics including the neurological consequences of fragmented sleep, the clinical basis for oral appliance therapy, sleep architecture and its disruption by snoring, and the practical decision-making process patients and clinicians navigate when choosing between CPAP and alternative interventions. Her writing brings academic rigor and clinical nuance to readers seeking reliable, medically authoritative guidance on sleep health.
Dr. Manu Chopra, MD
Pulmonologist & Sleep Medicine Writer
Dr. Manu Chopra is a pulmonologist and sleep medicine specialist at Army Research and Referral Hospital, New Delhi, where he practices as a Consultant and Interventional Pulmonologist. He holds an MD in Pulmonary Medicine from the Armed Forces Medical College (AFMC), Pune — one of India's most prestigious medical institutions — and his clinical skill set spans bronchoscopy, polysomnography, asthma management, COPD, and the full spectrum of sleep-disordered breathing from primary snoring through to severe obstructive sleep apnea. His work within a tertiary defence hospital setting exposes him to a high-acuity patient population where sleep disorders frequently intersect with cardiovascular and metabolic comorbidities.
Dr. Chopra's approach to sleep medicine is shaped by the clinical realities of treating sleep apnea in the Indian context — where CPAP adherence is notoriously challenging, where patients often present late with already-established sequelae, and where affordable, patient-tolerable oral appliance alternatives have an important role to play. His polysomnography expertise informs a nuanced understanding of sleep stage architecture and how disruption at different stages manifests differently in terms of cognitive, cardiovascular, and metabolic outcomes. He approaches PAP therapy and oral device prescription with a strong emphasis on patient adherence as the deciding clinical factor — the best device is the one the patient will actually use.
For Snorple, Dr. Chopra contributes content on the respiratory science of snoring, the cardiovascular and metabolic consequences of untreated sleep-disordered breathing, the practical case for oral appliance therapy versus CPAP, and the sleep medicine considerations relevant to South Asian patients and populations. His writing bridges the gap between clinical pulmonology and accessible patient education, drawing on his hospital-based practice to ground evidence in real-world clinical context.
Indu Vaishnavi, RD
Consultant Dietitian & Health Content Writer
Indu Vaishnavi is a Gold Medalist Consultant Dietitian based in Bengaluru, India, with over 12 years of experience spanning clinical nutrition, food safety, and health content creation. She holds an M.Sc in Food and Nutrition and is a Certified Food Safety Auditor (ISO 22000:2018 Internal Auditor) — credentials that reflect both her clinical depth and her systems-level understanding of nutrition in healthcare environments. She has served as a Corporate Nutritionist across healthcare and wellness organisations and maintains an active online counselling practice focused on lifestyle disorders including obesity, diabetes, and metabolic syndrome.
Her perspective on snoring is grounded in the dietary and lifestyle factors most commonly overlooked in clinical practice: how excess weight loads the upper airway, how alcohol relaxes pharyngeal musculature, how blood sugar dysregulation and chronic inflammation alter sleep architecture, and how micronutrient deficiencies affect airway muscle tone and mucosal health. With more than a decade of patient counselling experience, she understands how the same physiological mechanisms that drive metabolic disease also drive sleep-disordered breathing — and how sustainable dietary change can reduce snoring severity independently of device-based interventions.
For Snorple, Indu contributes content covering the nutritional and lifestyle dimensions of snoring — including weight management, anti-inflammatory eating, hydration, gut microbiome health, and the evidence linking specific dietary patterns to reduced sleep-disordered breathing. Her writing brings a practical, evidence-informed dietitian's perspective to readers who want to understand not just what devices can do, but what lifestyle changes can achieve alongside them.
