Sleep Apnea Treatment in Hyderabad
You stop breathing dozens — sometimes hundreds — of times each night. Your brain rouses you each time to restart breathing. You never enter deep sleep. You wake exhausted, having "slept" 7–8 hours.
This is sleep apnea. It is not snoring. It is a medical condition — and it is fully treatable.
Sleep Apnea in Hyderabad
Urban lifestyle, sedentary IT-sector work patterns, and South India's high prevalence of Type 2 diabetes make Hyderabad a high-risk city for obstructive sleep apnea.

What Is Sleep Apnea?
A disorder where the airway repeatedly collapses during sleep — blocking breathing, dropping oxygen, and fragmenting sleep — every single night.
What Happens During an Apnea
- Throat muscles relax → airway narrows or collapses
- Blood oxygen (SpO2) falls — sometimes below 80%
- Brain detects hypoxia → triggers arousal response
- You partially wake, restart breathing — often without knowing
- This cycle repeats — 5 to 100+ times per hour
The AHI — How Severity Is Measured
Apnea-Hypopnea Index = number of breathing events per hour of sleep
- Normal: AHI below 5
- Mild OSA: AHI 5–14
- Moderate OSA: AHI 15–30
- Severe OSA: AHI above 30
- Treatment recommended above AHI 5 with symptoms
Chronic but Treatable
- CPAP therapy eliminates events in 90%+ of patients
- Most patients feel significantly better within 1–2 weeks
- Blood pressure often improves without medication changes
- Cardiovascular risk reduces substantially with treatment
- Weight loss in obese patients can resolve OSA entirely
Types of Sleep Apnea
The type determines the treatment. OSA and CSA require different approaches — misidentification leads to ineffective therapy.
Obstructive Sleep Apnea (OSA)
The airway physically collapses due to relaxed throat muscles, enlarged tonsils, or excess tissue. Oxygen falls. Brain triggers arousal. Treated effectively with CPAP/APAP.
- Loud snoring
- Witnessed pauses
- Gasping on waking
- Daytime sleepiness
Central Sleep Apnea (CSA)
The brain fails to send the signal to breathe — not an airway obstruction issue. Associated with heart failure, opioid use, high altitude, and stroke. CPAP alone is insufficient; BiPAP or ASV therapy needed.
- No snoring (airway is open)
- Associated with heart failure
- No airway obstruction
- Requires BiPAP or ASV
Complex Sleep Apnea Syndrome
Also called treatment-emergent central sleep apnea — OSA patients who develop central apneas after starting CPAP therapy. Requires ASV (Adaptive Servo-Ventilation) or BiPAP-ST. Needs specialist assessment.
- Starts as OSA
- CSA emerges on CPAP
- Requires ASV therapy
- Specialist evaluation needed
UARS (Upper Airway Resistance Syndrome) is a related condition where the airway partially narrows — not enough to cause measurable apneas, but enough to fragment sleep and cause fatigue. AHI may be normal; diagnosis requires assessment of respiratory effort-related arousals (RERAs).
Signs and Symptoms of Sleep Apnea
Sleep apnea has two faces — what happens at night and how you feel during the day. Most patients focus only on snoring; the daytime symptoms are often the more damaging.
You may not be aware of the nighttime symptoms — your partner often notices them first.
Nighttime Symptoms
- Loud, chronic snoring — often described as disruptive
- Witnessed pauses in breathing by a partner
- Gasping, choking, or snorting sounds during sleep
- Waking up feeling breathless or with chest tightness
- Nocturia — waking to urinate 2–3 times per night
- Night sweats unrelated to temperature
- Restless sleep, tossing and turning
- Teeth grinding (bruxism) — common OSA association
Daytime Symptoms
- Excessive daytime sleepiness — falling asleep during meetings, driving
- Morning headaches — from CO₂ retention and hypoxia overnight
- Cognitive fog — poor memory, difficulty concentrating
- Irritability, mood swings, anxiety, depression
- Dry mouth or sore throat on waking
- Decreased libido and sexual dysfunction
- Uncontrolled hypertension despite medication
- Poor exercise tolerance — fatigue on minimal exertion
Could This Be Sleep Apnea?
You don't need to have every symptom. If you recognise two or more of these — it warrants investigation.
Your partner says you snore loudly
You wake up tired after a full night of sleep
You fall asleep easily during the day
You have been told you stop breathing during sleep
You have uncontrolled blood pressure
You wake with a headache or dry mouth regularly
You get up to urinate 2+ times per night
You have Type 2 diabetes or are overweight
If you checked even two of these — a home sleep study will give you a definitive answer.
You sleep in your own bed. Results are ready in 24–48 hours.

How We Diagnose Sleep Apnea — Not Guesswork
We do not prescribe CPAP based on symptoms alone. Every patient receives objective testing before treatment begins.
Home Sleep Apnea Test (HSAT)
Recommended first-line for most patients
- Sleep in your own bed — no hospital admission
- Measures: SpO2, heart rate, airflow, respiratory effort, body position
- Results and AHI calculation within 24–48 hours
- Accurate for moderate-to-severe OSA
- Significantly lower cost than in-lab PSG
Device collected and returned from Respire Basheerbagh or Jubilee Hills clinic
Polysomnography (PSG)
Full in-lab sleep study — for complex cases
- Full EEG, EMG, EOG + respiratory monitoring
- Gold standard — captures all sleep stages
- Required for suspected CSA, narcolepsy, or UARS
- Split-night option: diagnose + titrate CPAP in one night
- Recommended when HSAT is inconclusive

Causes and Risk Factors for Sleep Apnea
OSA is multifactorial. Anatomy, weight, age, hormones, and lifestyle all contribute — often together.
Obesity and Excess Weight
The single biggest modifiable risk factor. Fat deposits around the neck (>40 cm in women, >43 cm in men) narrow the airway. A 10% increase in body weight increases OSA risk by six times.
Upper Airway Anatomy
Large tonsils or adenoids, retrognathia (receding jaw), macroglossia (large tongue), elongated uvula, or low-set soft palate — all reduce airway space and increase collapse risk.
Age
Muscle tone decreases with age, making the upper airway more collapsible. Prevalence increases significantly after age 50. However, OSA affects all age groups including children.
Male Sex
Men are 2–3× more likely to have OSA than premenopausal women. Testosterone promotes central fat deposition and reduces upper airway muscle tone. Post-menopausal women approach male risk levels.
Type 2 Diabetes
60–70% of patients with T2DM have OSA — and vice versa. Insulin resistance, autonomic neuropathy affecting pharyngeal muscles, and shared obesity link both conditions. Treating OSA improves glycaemic control.
Alcohol, Sedatives, and Opioids
All relax pharyngeal muscles and reduce the arousal response, worsening OSA severity significantly. Even moderate alcohol before sleep doubles breathing events in OSA patients.
Sleeping Position
Supine (back) sleeping increases OSA severity. Gravity causes the tongue and soft palate to fall back, narrowing the airway. Positional OSA — where severity drops significantly on the side — is common.
Nasal Obstruction
Chronic nasal congestion (from allergic rhinitis, deviated nasal septum, or nasal polyps) forces mouth breathing, destabilising the upper airway and worsening OSA. Treating nasal obstruction often reduces CPAP pressure requirements.
Sleep Apnea Treatment at Respire
Treatment is matched to severity, anatomy, and patient preference. We do not prescribe CPAP to everyone. We prescribe the right treatment.
Mild OSA
AHI 5–14
- APAP therapy (auto-titrating CPAP)
- Weight loss programme if BMI > 25
- Positional therapy if supine-predominant
- Mandibular advancement device (MAD)
- Treat underlying nasal obstruction
- Alcohol and sedative reduction counselling
Moderate OSA
AHI 15–30
- CPAP or APAP — first-line treatment
- Nasal interface fitting (pillow, mask, or full-face)
- Heated humidifier to reduce dryness and leaks
- ENT evaluation for structural correction
- Lifestyle: weight loss + sleep position + alcohol
- Follow-up at 4–6 weeks with machine data review
Severe OSA
AHI > 30
- CPAP/BiPAP — urgent initiation
- BiPAP for CPAP-intolerant patients or CSA
- Oxygen supplementation if SpO2 dips below 88%
- Cardiovascular risk management (BP, ECG, echo)
- Surgical evaluation for anatomic correction
- Bariatric referral if BMI > 35
Why CPAP Therapy Fails
- Wrong mask type — leaks cause ineffective therapy and noise
- Fixed pressure too high or too low — APAP mode resolves this
- No humidifier — dryness causes mouth breathing and aerophagia
- Claustrophobia — nasal pillow interface often resolves this
- Not using it — patients stop because of discomfort, not the condition
- CSA or complex apnea — CPAP is the wrong treatment
What Makes Treatment at Respire Different
- Machine data reviewed at every follow-up — AHI on therapy confirmed
- Mask fitting by our team — not left for you to figure out
- APAP preferred over fixed CPAP — self-adjusts to your breathing pattern
- ENT + pulmonology in one clinic — anatomy and physiology both addressed
- Intolerant patients switched to BiPAP, MAD, or surgery — never abandoned
- Long-term monitoring — not just initial setup
What You Can Expect After Starting Treatment
Mental Clarity
Cognitive fog lifts — often within 1–2 weeks of consistent use
Energy Returns
Daytime sleepiness resolves — often dramatically in the first month
Blood Pressure
Systolic BP drops 2–10 mmHg on average — reduces medication dependence
Sleep Quality
Deep sleep (stages 3 and 4) restored — waking refreshed after years of fragmentation
Stop Waking Up Exhausted
A home sleep study is all it takes to confirm or rule out sleep apnea. You do it in your own bed. Results in 48 hours.
Book a ConsultationCPAP Therapy — What You Need to Know
CPAP (Continuous Positive Airway Pressure) is the gold-standard treatment for OSA — but it is not one machine and one mask. Matching the device and interface to the patient is critical.
CPAP
Continuous Positive Airway Pressure
Delivers one fixed pressure throughout the night. Pressure is set based on titration study results. Best for patients with consistent, predictable obstruction.
Best for: Moderate-to-severe OSA with known fixed pressure requirement
APAP
Auto-Titrating Positive Airway Pressure
Adjusts pressure breath-by-breath within a set range based on detected airway resistance. Most patients find this better tolerated than fixed CPAP — lower average pressure while maintaining therapeutic effect.
Best for: First-line for most OSA patients. Preferred at Respire.
BiPAP
Bilevel Positive Airway Pressure
Delivers two separate pressures: higher IPAP on inhalation, lower EPAP on exhalation. Easier to breathe against than CPAP. Required for central apnea, overlap COPD+OSA, or CPAP-intolerant patients.
Best for: CSA, overlap syndrome (COPD+OSA), CPAP failure, or very high pressure requirements
Mask Types — The Most Overlooked Part of CPAP Success
Nasal Pillow
Small cushions that seal at the nostril entrance. Minimal contact, no claustrophobia. Best for: side sleepers, claustrophobia, glasses wearers, low pressure requirements.
✓ Least intrusive
✗ Not for mouth breathers
Nasal Mask
Covers the nose only. Good seal, handles higher pressures. Comfortable for most patients. Best for: active sleepers, moderate-to-high pressure, patients who breathe through the nose.
✓ Best for most patients
✗ Mouth breathing causes leaks
Full Face Mask
Covers nose and mouth. Handles mouth breathing effectively. Required for patients who cannot breathe through the nose. Higher risk of aerophagia at high pressures.
✓ Works for mouth breathers
✗ More intrusive, harder to fit

Sleep Apnea and Coexisting Conditions
Sleep apnea rarely exists in isolation. Treating it often improves conditions that appeared unrelated.
Hypertension
Found in 50% of OSA patientsOSA causes a surge in sympathetic nervous activity with each apnea — raising blood pressure acutely and chronically. 50% of OSA patients have hypertension, and 30% of hypertension patients have OSA. CPAP therapy reduces systolic BP by 2–10 mmHg on average, sometimes eliminating the need for one antihypertensive.
Atrial Fibrillation
2–4× increased risk in untreated OSAOSA is a major independent risk factor for AF — nocturnal hypoxia, sympathetic activation, and negative intrathoracic pressure changes stretch the left atrium. AF recurrence after cardioversion is significantly higher in untreated OSA. Cardiologists increasingly screen all AF patients for sleep apnea.
Type 2 Diabetes
60–70% of T2DM patients have OSAOSA impairs insulin sensitivity through intermittent hypoxia and sleep fragmentation. HbA1c improves modestly with CPAP therapy. 60–70% of T2DM patients have coexisting OSA — often undiagnosed. Screening is recommended in all patients with poorly controlled diabetes.
Depression and Anxiety
OSA frequently misdiagnosed as depressionMany patients with OSA are diagnosed with depression or anxiety when sleep deprivation is the root cause. OSA-related fatigue, irritability, cognitive fog, and reduced libido are mistaken for primary psychiatric illness. CPAP therapy often resolves depressive symptoms without antidepressants.
COPD + OSA (Overlap Syndrome)
Worse outcomes than either condition aloneWhen COPD and OSA coexist, the combination is far more dangerous than either alone — more severe oxygen desaturation, higher risk of pulmonary hypertension, and greater mortality. BiPAP is preferred over standard CPAP. Requires careful titration and specialist management.
See our COPD + OSA (Overlap Syndrome) page →GERD (Acid Reflux)
Bidirectional relationship — each worsens the otherNegative intrathoracic pressure during apnea events literally sucks acid up the oesophagus. GERD is significantly more common in OSA patients. Both conditions worsen each other. CPAP therapy reduces nocturnal GERD events in many patients.
Conditions That Can Mimic Sleep Apnea
Daytime fatigue and poor sleep have many causes. Objective testing is the only way to confirm sleep apnea.
We do not diagnose on symptoms alone.
Insomnia
Overlap: Fatigue, poor sleep, cognitive fog
Insomnia = difficulty falling or staying asleep despite opportunity. OSA = fragmented sleep from breathing events. Can coexist (COMISA). PSG distinguishes both.
Narcolepsy
Overlap: Excessive daytime sleepiness, sleep attacks
Narcolepsy involves cataplexy, hypnagogic hallucinations, and REM intrusion. PSG + MSLT (Multiple Sleep Latency Test) confirms. Often coexists with OSA.
Hypothyroidism
Overlap: Fatigue, weight gain, cognitive fog, snoring
Hypothyroidism causes myxoedema of the tongue and pharynx — worsening or causing OSA. TSH screening is part of our sleep apnea workup for all patients.
Depression
Overlap: Fatigue, poor sleep, cognitive impairment, reduced libido
OSA frequently masquerades as depression — same symptoms, different cause. If antidepressants aren't working, investigate sleep. ESS and HSAT clarify.
Restless Leg Syndrome / PLMD
Overlap: Disrupted sleep, daytime sleepiness
RLS causes uncomfortable leg urges at rest; PLMD causes periodic limb movements during sleep — both fragment sleep. PSG with EMG differentiates from OSA.
Circadian Rhythm Disorder
Overlap: Sleepiness, sleep-wake misalignment, fatigue
Shift workers and IT professionals often have circadian rhythm disruption — similar fatigue and cognitive symptoms. Actigraphy + sleep diary over 2 weeks distinguishes from OSA.
Sleep Apnea in Special Populations
Presentation, diagnosis, and treatment differ across groups. Generic advice misses these nuances.
Women
- Present with fatigue, insomnia, and depression — not classic snoring
- Often treated for mood disorders when OSA is the cause
- Menopausal women lose protective effect of progesterone — risk approaches male levels
- Require lower diagnostic AHI threshold for symptom-based diagnosis
- CPAP compliance is often better in women once correctly diagnosed
Children
- Adenotonsillar hypertrophy is the main cause in children — different from adults
- Presents with hyperactivity, ADHD-like behaviour, bedwetting, and poor school performance — not sleepiness
- Adenotonsillectomy is first-line treatment — curative in many cases
- Weight-related OSA in obese children mirrors adult disease
- Paediatric CPAP available with child-specific mask sizing
IT Sector & Night Shift Workers
- Hyderabad's largest at-risk group — sedentary work, stress eating, irregular sleep schedules
- Night shifts disrupt circadian rhythm — worsening sleep quality and OSA severity
- High BMI from desk work and irregular meal patterns increases anatomic risk
- High-pressure work culture delays help-seeking despite significant symptoms
- APAP therapy adapts to variable sleep schedules better than fixed CPAP
Elderly
- OSA prevalence increases significantly after age 65
- Comorbidities (heart failure, stroke, diabetes) worsen OSA severity
- Cognitive impairment may be partially driven by untreated OSA
- Tolerates CPAP well when correctly fitted and followed up
- CSA more common in elderly due to heart disease — BiPAP preferred in some cases

What is the Apnea-Hypopnea Index (AHI)?
AHI is the number of apnea (complete breathing stop ≥10 seconds) and hypopnea (partial reduction ≥30%) events per hour of sleep. Mild OSA: AHI 5–14. Moderate: 15–30. Severe: above 30. Treatment is recommended above AHI 5 with symptoms, or above 15 regardless of symptoms.
Can sleep apnea be diagnosed at home?
Yes. A Home Sleep Apnea Test (HSAT) measures breathing, oxygen levels, heart rate, and body position during sleep — in your own bed. Results and AHI calculation are available within 24–48 hours. HSAT is accurate for moderate-to-severe OSA. Respire provides the device; you collect it from the clinic.
Is CPAP therapy permanent?
For most patients, CPAP is a long-term treatment because sleep apnea is a chronic condition. However, significant weight loss (10–15% of body weight) can resolve OSA in obese patients. CPAP is used nightly — skipping nights leads to return of symptoms and cardiovascular risk.
What if I cannot tolerate CPAP?
CPAP intolerance is common but addressable. Mask fit issues, pressure discomfort, and claustrophobia are the main causes. Switching to a nasal pillow interface, using APAP mode, adding a heated humidifier, or trying BiPAP resolves most issues. For genuine CPAP failure: oral appliances (MAD) or surgical correction are alternatives.
Does sleep apnea cause heart problems?
Yes. Untreated OSA significantly increases risk of hypertension (50% of OSA patients), atrial fibrillation, heart failure, and stroke. Each apnea episode causes an acute blood pressure surge and sympathetic activation. Treating OSA reduces cardiovascular event risk.
What is the difference between CPAP, BiPAP, and APAP?
CPAP delivers one fixed pressure throughout the night. APAP adjusts pressure breath-by-breath — better tolerated, preferred for most patients. BiPAP delivers two pressures: higher on inhalation (IPAP), lower on exhalation (EPAP) — used for central apnea, COPD overlap, or CPAP intolerance.
Can women have sleep apnea?
Yes — and OSA is significantly underdiagnosed in women. Women present with fatigue, insomnia, and depression rather than classic snoring. Menopause markedly increases risk — oestrogen and progesterone protect the upper airway. Many women are treated for mood disorders when sleep apnea is the actual cause.
How long before I feel better on CPAP?
Most patients notice improved sleep quality within 1–2 weeks. Daytime sleepiness often improves within days. Blood pressure benefits accumulate over months. Consistent use — at least 4 hours per night — is required for full therapeutic benefit.
You're Not Just Tired. You're Untreated.
Millions of people in India live with undiagnosed sleep apnea — accepting exhaustion as normal. A home sleep study changes that. One night. One test. A clear answer.
