Medication
When this happens, symptoms may include:
- confusion
- congestion
- coughing
- chest tightness
- decreased consciousness
- paleness or skin discoloration due to the lack of oxygen
Therapy
- Give yourself 2 to 4 days at a slightly lower elevation to adjust to the altitude.
- Avoid exercising vigorously for the first 2 days after arriving at a high altitude.
- If you plan to travel to altitudes above 8,000 feet, it helps to descend at night so you can sleep at lower altitudes.
- Consider taking acetazolamide when you start your trip.
Self-care
Symptoms of high-altitude illness usually begin 12 to 24 hours after you reach a high altitude. Early symptoms include: Headache; Dizziness; Nausea; Trouble breathing when active; Weakness or fatigue; Trouble sleeping; Increased heart rate; If you have these symptoms, stop, rest, and drink water.

Can you get Diamox over the counter?
Acetazolamide is a prescription only medicine (POM).
When should I take Diamox?
Dose. Take one 125 mg tablet twice a day. Begin this medicine 24 hours before arriving at high altitude and continue for 48 hours while at high altitude. You may continue taking Diamox up to 48 hours longer if your symptoms indicate the need for additional pills.
Why is Diamox used for altitude sickness?
It starts to breathe deeper and faster, getting rid of the carbon dioxide, and also taking in more oxygen. In effect, the increased oxygen speeds up the acclimatisation process. It also greatly reduces you of any symptoms of altitude sickness.
Should I take Diamox to prevent altitude sickness?
Acetazolamide, or Diamox, is the standard medical prophylaxis agent for high altitude illness. The medication is effective in preventing acute mountain sickness (AMS), high altitude pulmonary edema (HAPE), and high altitude cerebral edema (HACE).
How does dexamethasone work for altitude sickness?
A single dose of intravenous dexamethasone given after 8 hours in normobaric hypoxia at 12% inspired oxygen concentration (FiO2) reduces the incidence or severity of the symptoms of AMS, as determined by MRI changes due to cerebral oedema.
How does acetazolamide work?
Mechanism of Action Acetazolamide is a carbonic anhydrase inhibitor. That means this drug works to cause an accumulation of carbonic acid by preventing its breakdown. The result is lower blood pH (i.e., more acidic), given the increased carbonic acid, which has a reversible reaction into bicarbonate and a hydrogen ion.
What is an alternative to Diamox?
Between 19–48% of patients will not tolerate acetazolamide due to side effects (5,6) and consequently alternative drugs maybe prescribed such as topiramate, furosemide, amiloride and octreotide. However, there is extremely limited mechanistic and clinical data to support their use.
Who should not take Diamox?
You should not use Diamox if you are allergic to it, or if you have: severe liver disease, or cirrhosis; severe kidney disease; an electrolyte imbalance (such as acidosis or low levels of potassium or sodium in your blood);
Is Diamox worth taking?
Several studies have confirmed that trekkers who take low doses of Diamox, in conjunction with a good acclimatization protocol, are less likely to develop mountain sickness, and if they do, it's usually less severe. Diamox is used as a preventative measure (prophylaxis) and does not cure altitude sickness.

What is the best way to get energy at altitude?
Eat Carbs: Carbohydrate is the preferred energy source at altitude. Carbohydrate replaces depleted muscle glycogen, prevents muscle from being used as energy, and requires less oxygen for metabolism. Glycogen is a form of sugar stored in muscles. A high-carbohydrate diet can reduce the onset and severity of Acute Mountain Sickness or (AMS) ...
How does altitude affect water?
Altitude increases water losses from the lungs due to the cold, dry air. There is also increased urinary loss of water because altitude and cold have diuretic affect. Sweating adds to the water loss. Drink a minimum of 1 quart of water every three hours.

What happens when you climb high above the altitude?
Rapidly ascending above altitudes of 8,200 feet (2,500 meters) from lower elevations can result in illness ranging from mild nausea and headaches, to life-threatening edema of the lungs or brain. Truth is, there is little data to help physicians prevent or treat high-altitude illnesses, or to counsel patients with confidence as to their risk. A recent New England Journal of Medicine review by Peter Bärtsch and Erik Swenson summarizes what's known and what's not about illnesses resulting from high-altitude ascents.

What is the best medicine for altitude sickness?
Acetazolamide is one of the medications for the prevention and treatment of altitude sickness. It increases the breathing rate allowing more oxygen to be taken in. This helps the body adjust to higher altitudes faster and reduces some of the symptoms of altitude sickness.
Why do people get altitude sickness?
Altitude sickness is directly related to how rapid the climb to high altitude is. It is more likely to occur if the climbs are more difficult and take more strength and energy than with a slow and easy climb. Some of the factors that determine a person’s risk for altitude sickness are: Genetic makeup. A history of previous altitude sickness.
What is the term for a group of symptoms that occur when you climb a mountain?
What is altitude sickness? Altitude sickness or mountain sickness, also called acute mountain sickness (AMS), refers to a group of symptoms occurring on climbing or walking to a higher altitude or elevation too quickly. Since the body is unable to take in enough oxygen, breathing becomes difficult.
What factors determine a person's risk for altitude sickness?
Some of the factors that determine a person’s risk for altitude sickness are: Genetic makeup. A history of previous altitude sickness. Residing at an altitude below 3,000 ft. Presence of respiratory infections or diseases. Obesity. A rapid rate of ascent. Over-exertion before the climb.
What does it mean to go down to a lower altitude?
It means to go down to a lower altitude as swiftly and safely as possible. For mild headache, rest and over-the-counter pain killers may provide relief. Most of the symptoms will typically go away quickly at a lower altitude. Maintaining adequate water intake may help.
Does inflating a bag help with altitude sickness?
On inflating, the bag increases the oxygen concentration. This allows the person in the bag with altitude sickness to breathe in more oxygen. This simulates going to a lower altitude. Having 70% of the diet as carbohydrates may also keep AMS at bay. Acetazolamide is one of the medications for the prevention and treatment of altitude sickness.
Can altitude sickness cause headaches?
The swelling puts pressure on the brain, squeezing it against the skull. Altitude sickness may rarely advance to a more severe form of the illness called high altitude cerebral edema (HACE).
How does altitude affect cooking?
Cooking at a high altitude requires some special considerations. The thin air — less oxygen and atmospheric pressure — affects both the time and the temperature of most everything that's cooked.
Why does it take longer to cook food at higher elevations?
Because water boils at a lower temperature at higher elevations, foods that are prepared by boiling or simmering will cook at a lower temperature, and it will take longer to cook. High altitude areas are also prone to low humidity, which can cause the moisture in foods to evaporate more quickly during cooking.
Which states are at high altitude?
Most of the western United States (Alaska, Arizona, California, Colorado, Idaho, Montana, Nebraska, New Mexico, Nevada, Oregon, South Dakota, Texas, Utah, Washington, and Wyoming) are wholly or partly at high altitude, however many other states contain mountainous areas that are also well above sea level.
