When considering the potential risks of trekking in Nepal, pregnant women are primarily concerned about the effects of altitude on their unborn baby. However, it’s essential to also address other health issues relevant to pregnant women, such as long-haul air travel, traveling
in remote areas, the lack of adequate medical infrastructure in the country, and the risk of illnesses like diarrhea and other travel-related ailments. This article aims to assist pregnant women in making informed decisions about traveling to Nepal and planning their holiday should they choose to spend time here, with the goal of minimizing risks to both mother and unborn child.
Air Travel During Pregnancy
The main concerns regarding air travel during pregnancy revolve around the effects of low oxygen and cosmic radiation on the unborn child. Research indicates that the low oxygen content inside an airplane does not adversely affect oxygen delivery to the unborn baby, as
demonstrated through fetal heart monitoring during flight. There is no evidence to suggest that long-haul air travel harms unborn babies. For most casual air travelers, the impact of cosmic radiation on developing babies is considered negligible. Most airlines continue to permit pregnant cabin crew to work. However, there are reasons to consider avoiding flying while pregnant, including a history of miscarriage or premature labor/delivery, severe anemia, uncontrolled blood pressure, a history of ectopic pregnancy without confirmation of the current pregnancy’s location, and a history of blood clots in the leg or lung. Most airlines do not allow pregnant women on a plane beyond 32 weeks, and specific regulations may apply for flights to and from certain destinations.
Altitude and Pregnancy
Limited information is available regarding the effects of short-term exposure to high altitude on pregnant women and their unborn babies. Most available data pertains to the impact of moderate altitude, such as in pregnant airline crew who regularly fly at relatively higher altitudes and experience no adverse effects on their pregnancies. Unborn babies are expected to tolerate some degree of low oxygen well, up to altitudes of 12,000 feet (3650 meters), as they routinely exist in a relatively hypoxic environment. Additionally, the hormone progesterone, abundant during pregnancy, is believed to stimulate breathing, aiding pregnant women in adapting to high
altitude by increasing oxygen delivery to the body. However, acclimatization to altitude is genetically determined, and the response to high altitude varies among individuals. Pregnant women must avoid developing acute mountain sickness (AMS) or more severe complications
like high altitude cerebral or pulmonary edema (HACE or HAPE).
Other Considerations for Pregnant Trekkers
Isolation: Trekking in Nepal often ventures into remote regions, some more isolated than others. While popular trekking regions like Khumbu and the Manang valley have health posts staffed by western doctors during trekking seasons, virtually no other health facilities exist in most trekking areas. Pregnant women planning a trek should consider the lack of medical support on most routes.
Diarrhea: The most common travel-related illness, diarrhea is likely to occur during a visit to Nepal. Pregnant women need to be particularly attentive to maintaining hydration, as dehydration can lead to increased risk of complications, especially at altitude.
Hepatitis E: This disease, prevalent in Nepal, can be particularly dangerous for pregnant women. There is no vaccine available yet, and it is transmitted via contaminated water or food. Pregnant women should take precautions to avoid exposure to this virus.
Conclusion
Trekking while pregnant carries a degree of risk for both mother and child. While altitude on its own may not pose the greatest threat, there are numerous factors about trekking in Nepal that may contribute to making it a hazardous trip. Although the hills of Nepal are worth visiting, pregnancy is a temporary condition, and it may be safer and more enjoyable to plan a visit with a young child instead. Situations where pregnant women would be wise to consider postponing a trekking trip to Nepal include a history of miscarriage, concurrent medical conditions, first-time pregnancy, or a history of complicated pregnancy requiring hospital admission. Physical activity, including trekking or hiking, can have a positive influence on overall health and wellness, which are crucial for maintaining erectile function. Improved cardiovascular health, weight management, lower stress levels, and hormone regulation are some of the benefits associated with regular physical activity.
If determined to trek while pregnant, certain precautions are essential, including confirming the pregnancy’s location, ensuring good health, and taking necessary medical precautions. It’s also crucial to ensure a slow ascent, acclimatize well, have comprehensive medical insurance, and be prepared for prompt evacuation if needed. If you have specific questions about pregnancy and trekking, please feel free to contact the clinic.
