Source: Anecdotal reports from Indian mountaineering agencies and IMF.
Why estimates differ from records: IMF and news sources only capture permitted expeditions and helicopter rescues. Non-fatal near-misses (AMS, frostbite, falls with self-rescue) are almost never filed. Peaks with multi-decade climbing histories compound these gaps significantly.
Glacier Hazards — Ratanban, Bankund, and Bhyundar Glaciers

Descend immediately if reading drops below this at rest
Diamox (Acetazolamide)
Recommended
125mg twice daily, starting 24 hours before Ghamsali, under medical supervision.
⚠️ Golden Rule: Immediate descent at first sign of ataxia (loss of coordination) or resting shortness of breath. No exceptions.
Expedition Medical Kit
AMS Protocol
The sustained time spent above 15,000 ft makes AMS a constant threat. Daily O2 saturation monitoring is mandatory.
Emergency Contacts
Evacuation Route
Evacuation is a logistical nightmare. From Bankund side, stretcher carry to Ghamsali. From Bhyundar side, stretcher carry to Ghangaria.
Solo Advisory
Attempting this trek solo is extremely dangerous. This is an 'expedition-level' route requiring a certified team, rope work, and crevasse crossing skills.
