For some hunters, it’s pukey at the top.

“Man, I feel like I’m getting the flu.”

Mark Cousins, hunter education coordinator for the Colorado Division of Parks and Wildlife, wishes he’d get a big game preference point for every time he heard somebody hunting in the mountains say that.

However, it’s not the flu that’s causing that throbbing headache and nausea. The more likely culprit is acute mountain sickness or AMS.

“For hunters who have traveled across the country for a Colorado hunt of a lifetime, the last thing they want to happen is end up curled up in a ball, throwing up,” Cousins said. “However, about 20 to 30 percent of people suffer from AMS to some degree.”

While flatlanders do run a risk of feeling the effects of AMS, even those living at 4,000 feet who take the fast track to the top can end up with it.

There is an easy cure. Cousins recommends dropping down to a lower elevation if you start feeling nauseous, tired, light-headed, short of breath and have a headache.

“Hunters who drive straight to 10,000 feet are courting trouble. They may feel great at first but it can come back to bite them by the second day,” Cousins said. “If you’re climbing above 8,000 feet, the smart thing to do is acclimate to the lower air pressure and oxygen levels by stopping to rest for a day or two every 2,000 feet.”

Cousins also recommends the following preventive measures:

  • Stay hydrated by drinking lots of fluids.
  • Eat regular meals that are high in carbs.
  • Cut back on caffeine and avoid adult beverages during story time around the campfire.
  • Visit your doctor before you hit the high country. If you’re a cancer survivor, have suffered a heart attack or lung disease, or are just out-of-shape, you’ll face special challenges hunting at high altitudes. Lower oxygen levels put additional strain on your cardiovascular system.

Hunters suffering from AMS who are too stubborn to retreat to lower elevations could wind up with more serious health issues. If left untreated, AMS can lead to fluid in the lungs, which is known as high-altitude pulmonary edema (HAPE). Another serious condition is high-altitude cerebral edema (HACE). Both conditions can be fatal.

According to Cousins, if you develop a fever and your breathing sounds wet and gurgley, it’s time to come down from the mountain because it could be pulmonary edema.

Cerebral edema symptoms include headache, fatigue, visual impairment, loss of coordination and even paralysis.

The best advice is to learn to recognize the symptoms of AMS, and seek relief immediately.
