Diamox (Acetazolamide) is worth discussing with your doctor if you plan to attempt Kang Yatse 1 Peak Expedition (20,997ft). It is not routinely required for healthy trekkers but is recommended if you have had AMS symptoms on a previous high-altitude trip. Never start Diamox without medical advice — it has side effects including tingling fingers and increased urination.

At 6,400m, a resting SpO2 below 80% is a medical emergency and requires immediate descent. Between 80–85% — monitor closely and do not ascend further. Most acclimatized trekkers maintain 85–92% at this altitude. Carry a pulse oximeter and check readings morning and night.

Solo expeditions are strictly discouraged. The route involves technical glacier travel, steep snow faces, and knife-edge ridges requiring a roped team.
