[Official sources ↗](https://ntb.gov.np/mount-manaslu)[What to recheck →](/data-methodology) Details and source context Status Planning guidance reviewed Applies to Manaslu Circuit Trek Last checked 21 Aug 2026 On this page ## Prevention - Discuss the risk during the pre-trek briefing. - Carry the required equipment and insurance details. - Report concerns early rather than protecting the schedule. - Give the guide authority to change the route for safety. ## If the problem occurs Headache with nausea, dizziness, fatigue or poor sleep after ascent can indicate AMS; stop ascent and report symptoms early. For AMS Symptoms on the Manaslu Circuit, stabilise the immediate situation, avoid further exposure, communicate clearly and document insurer or medical instructions. Severe altitude illness requires descent rather than waiting for a helicopter. ## Before leaving Kathmandu - Save documents offline. - Confirm emergency roles. - Check the group medical summary. - Verify communication equipment and battery power. ## Recognize a change early Symptoms can be confused with dehydration, exhaustion or a poor night's sleep, which is why timing and the full picture matter. A guide should record the recent sleeping elevation, ascent rate, symptoms, hydration, medication and response to rest. Do not hide a problem to protect the itinerary or group pace. Headache with nausea, dizziness, marked fatigue or reduced coordination deserves attention. Confusion, inability to walk normally, breathlessness at rest, a worsening cough or blue lips are emergency signs. The appropriate response may be descent and medical support, not a wait for a helicopter or another night's sleep. - Stop gaining altitude while symptoms are being assessed. - Tell the guide, companions and operator exactly what has changed. - Keep insurance details, emergency contacts and medication information accessible. ## Build a decision plan before the high stages Ask the operator how the group monitors health, who can call for help, where the lower sleeping options are and how transport or evacuation is coordinated. A licensed guide can help interpret symptoms, but the plan should also identify local medical support and the insurer's authorization process. Acclimatization comes from a gradual itinerary, sensible rest and the willingness to descend. Medication decisions belong with an appropriate clinician and do not make a rapid ascent safe. Keep the route flexible enough that one trekker can descend without forcing the rest of the group into a dangerous schedule. - Confirm acclimatization nights in the written itinerary. - Ask how an early descent affects rooms, transport and cost. - Never treat a fixed pass date as more important than health. ## AMS Symptoms on the Manaslu Circuit in your plan Before you book or set out for ams symptoms on the manaslu circuit, keep these details visible in the plan: 2026 guide: Updated; Restricted area: Guided; Conditions vary: Flexible; Field planning: Practical Use these details to decide whether the place or activity belongs in your trip.
