Is It Safe To Travel To A High Altitude While Pregnant
Yes: There are millions of people who live in high altitude areas of the world who are pregnant and do just fine. If you are not used to it you may be more prone to altitude sickness and feeling of shortness of breath though. For prolonged sitting during travel make sure you get up and walk every few hours to prevent blood clots. Support stockings on your feet prevent some swelling too. ...Read more
As one ascends through the atmosphere, every breath contains fewer molecules of oxygen. One must work harder to obtain oxygen, by breathing faster and deeper. The % of oxygen in the atmosphere at sea level is 21%. As altitude increases, the % remains the same but the number of oxygen molecules per breath is reduced. At 12, 000 feet 40% fewer oxygen molecules per breath. Your ...Read more
Yes: It is safe to travel to high altitude areas but you may experience shortness of breath faster than you would at home because of the lower oxygen levels. Pregnancy women who live in high altitude areas permanently actually experience different fetal growth curves but for a short vacation this is fine. ...Read more
Travel to high altitude (above 8000 ft / 2400 m) can be very stressful on both parents and babies. Babies have a limited ability to communicate if they are having difficulty at high altitude. Older children and adults are fatigued, have nausea & headache, and are short of breath. Waiting until the child is able to talk makes monitoring for altitude sickness symptoms easier.
Symptoms mean descend. ...Read more
How safe is it for someone who had been smoking for 27 yrs to move to a high altitude city of 5000 or 6000 ft elevation?
Is it safe to take a healthy 7 month old baby to high altitude, specifically Cusco, Peru (11, 000 ft.)?
Safe?: Possible, but why take the chance!Get a more detailed answer ›
2 yr old w/ history of chronic lung disease (bronchopulmonary dysplasia), recently d/c supplemental O2. Is it safe to travel to high altitudes?
1. You breath faster to compensate for the thinned density of oxygen.
2 body makes more oxygen carrying red cells at altitude
3. Kidneys put out more bicarbonate (sodium bicarbonate) to keep your acid base state adjusted. Your rapid breathing blows off carbon dioxide and your kidneys adjust for this change but it takes a few days to body to alter. There are medicines to speed this acclimatization. ...Read more
Not well studied: Very likely. The particular risks for children to high altitude have not been thoroughly studied. Children born ; living at altitude to have normal risk for high altitude pulmonary edema but there may be some increased risk for this condition if a child then travels down to lowland ; then re-enters high altitude. Very small older studies are suggestive but reasons are not clear. New info pending. ...Read more
Pacemakers: The function of a pacemaker is not affected by long distance flights or altitude. The patient's underlying disease process depending on what it is, could however be affected by either. ...Read more
Water and cardio: It is important to drink more water. Also, doing cardiovascular exercises can help aclimate you to the new environment sooner. I'm presuming that we are discussing places like colorado or similar mountain areas which are typically a mile above sea level. For extreme high altitudes, such as himalayan mountains, there are significant dangers from altitude and that is a more complicated answer. ...Read more
What do YOU mean by: "well controlled"? Asthma in america study reveals that most patients rating their asthma well controlled are not in control by the standards of allergists & pulmonologists. A simple yardstick is the rule of twos. Asthma is in control when albuterol use <3x/week & waking up at night from asthma <3x/month & exacerbation of asthma requiring Prednisone or er visit <2x/year. Pass & you're good to go. ...Read more
Can high altitude cause hypertension or aggravate it if it already exists? If so what causes this?
No, Internal Control: Bp: a result of cardiac output vs. Average resistance of the 20, 000 to 30, 000 end arteries (arterioles) which determine blood flow to each capillary bed, both co ; size of all arterioles (degree of constriction) are under split-second control from brain ; constantly being adjusted. BP is just a momentary result. Brain integrates many variables, including perceptions/feelings ; adjusts accordingly. ...Read more
What could it be to have high hemoglobin? No smoke, no live on high altitude, no kidney issues. Please help!
P vera is rare ; genetic. Be sure you are talking about truly high number.
Other causes are sleep apnea, lung disease, non smoking chronic carbon monoxide exposure, liver disease, kidney cysts or obstruction that may be unknown, adrenal causes, very rare tumors that put out EPO (which tell the body to make more hemoglobin) no need to guess though--your provider will be able to sort it out for you. ...Read more
Depends: This is a difficult one to answer. The changes that may occur at high altitude, such as relatively less oxygen may lead to increased heart rates, especially with exertion, and that is an undesirable effect. However, more details are needed: location of the aneurysm? Size and the etiology of the aneurysm? M how far above sea level is your location? What would be a rate of ascent? ...Read more
Yes, however:: At altitude above 4300 meters, there are certainly reports of retinal hemorrhage but it can be difficult to exclude other causes.High altitude retinopathy (harh) is seen in up to 29% of everest climbers above 5300 meters. There seems to be an association with altitude sickness raising questions whether slow ascent ; other factors may reduce risk for bleeding in the small vessels of the eye. ...Read more
It's possible...: ... But other causes should be ruled out. Retinal hemorrhages are more often caused by uncontrolled hypertension or diabetes, as well as occasional association with bad floaters. The decreased pressure from high altitude has been known to rupture small blood vessels on the white of the eye as well. Have your eye doctor examine you carefully. ...Read more
Spaced out Air!: As one ascends through the atmosphere, every breath contains fewer molecules of oxygen. One must work harder to obtain oxygen, by breathing faster and deeper. The % of oxygen in the atmosphere at sea level is 21%. As altitude increases, the % remains the same but the number of oxygen molecules per breath is reduced. At 12, 000 feet 40% fewer oxygen molecules per breath. Your body has to cope! ...Read more
1.Your bone marrow will makes more oxygen carrying red cells at altitude
2.The body produces more of a particular enzyme which increases release of oxygen from hemoglobin to the body tissues
3.Your kidneys adjust the acid base state of your body by changing amount bicarbonate (sodium bicarbonate) excreted.
4. Pulmonary capillary pressure increases, forcing parts of the lung to work that are dormant at sea level. ...Read more
Hemoglobin at altitu: Weeks to months depending on the altitude. The immediate response to altitudes over 10, 000 feet is an increase in the depth and rate of breathing to help maintain the level of oxygen in the blood. As the length of exposure persists, the kidneys will start producing a hormone to increase the rate of production of red blood cells to pick up and carry more of the available oxygen at that altitude. ...Read more
Altitude Sickness: Leh, altitude 11500 ft (3500 m), is at the defined border between high and very high altitude. Low o2, pulmonary and cerebral edema are the main concerns with altitude sickness, which is made worse by rapid ascent. Precautions and treatment will depend on your health. You should consult with your physician about specifics. ...Read more
My BP suddenly went dangerously high after living at high altitude for over 6 months. What is the reason for this?
Not the cause: It's unlikely that altitude is the cause. See this science-based article from the u of hawaii: http://www. Ncbi. Nlm. Nih. Gov/pubmed/10453102. ...Read more
When your due date arrives, you will be more than ready to have your baby! Most women deliver the baby somewhere between 37 and 42 weeks. According to the American College of Obstetricians and Gynecologists, only 5% of babies arrive on the exact due date. Approximately 7% of babies are not delivered by 42 weeks, and when that happens, it is referred to ...Read more
