Acute Mountain Sickness generally develops within which time frame after ascent?

• A. Within 6-10 hours to 3 days
• B. 1 Week
• C. Immediately
• D. 2 Days

Answer: (A)

Acute Mountain Sickness appears after exposure to high altitude as the body struggles to compensate for lower oxygen. The typical window for symptom onset is within the first day to a couple of days after ascent, most often within 6–12 hours, but it can start as early as about 6–10 hours and may persist for up to around 3 days if no acclimatization occurs. So the broad range of 6–10 hours to 3 days best fits how AMS usually presents. Options like a full week or immediate onset don’t fit the usual timeline, and while two days is possible, it doesn’t encompass the full common window as effectively.
