Possible AMS after arriving in Leh — advice before Khardung La?
Hi everyone, I'm in Leh for a 7-day bike trip and would appreciate some advice.
Flew Delhi → Leh yesterday (18 Aug), arriving around 9:30 AM after a very sleep-deprived journey. Developed a 4–5/10 throbbing headache, which got worse at night along with nausea and dizziness. Took Ondem-MD + paracetamol around 3–4 AM and slept.
Today (19 Aug) I feel substantially better. There is no headache or nausea. No breathlessness at all. However, my Noise smartwatch showed SpO₂ around 80%.
I am a little scared due to this. Is 80% a normal reading? Our itinerary as part of a tour group is:
18–19: Leh/rest and acclimatization
20: Leh local sightseeing on bike
21: Khardung La → Nubra
Then Turtuk → Pangong → Leh ending on 25th.
We'll only spend a short time at Khardung La and descend afterward.
Were my symptoms AMS, sleep deprivation/dehydration, or a combination? And if I'm completely symptom-free by the 21st, would you consider the Khardung La ride reasonable?
Thanks!
