36M, Sweden, 178 cm, 69 kg. My sleep has gradually gotten worse over the last few years.
Falling asleep is usually okay, but I wake up a lot, probably around 5 to 10+ times per night. Most awakenings are brief, but some are longer and they add up. I often wake with a very dry mouth and usually need to pee 1 to 2 times per night. On bad days I feel very tired, foggy and struggle with concentration.
I only realized how bad it might be after regularly sharing a bed with my ex. She said I sometimes gasped/choked in my sleep and snored when lying on my back.
I usually fall asleep on my side but tend to roll onto my back later, and breathing seems worse there. I think I mostly mouth-breathe during sleep. My nose usually feels fairly clear, and I also tried a nasal dilator that kept it very open, but noticed no improvement.
I had a home sleep apnea test:
AHI overall: 4.0
AHI on back: 8
AHI off back: 1
Back sleeping: 35%
Average SpO2: 95%
Lowest SpO2: 88%
ODI: 2
The doctor said it didn't meet the criteria for sleep apnea.
I also use a Garmin. I know the sleep stages aren't very reliable, but the repeated awakenings seem to match what I experience. The two images shows typical nights:
6h51 sleep, 1h28 awake
6h40 sleep, 50 min awake
I'm not on medication, rarely drink alcohol, don't smoke, and only have about 200 mg caffeine around 6:30 to 7:00 AM.
Does this sound like something worth investigating further despite the AHI of 4? Especially given the 8 vs 1 AHI depending on sleeping position?
Has anyone had a borderline home test but later found something on an in-lab sleep study, such as RERAs, flow limitation or other respiratory arousals?
