The incidence of acute altitude sickness was positively correlated with male body mass index (weight/height 2) (P < 0.05), but not with female body mass index, indicating that obese men are more susceptible. People who can't go in particular: obese men had better not go.
Extended data:
The speed and degree of altitude maladjustment determine the clinical manifestations of acute relief of altitude sickness. Acute mountain sickness can be divided into three types, namely, acute altitude sickness, altitude pulmonary edema and altitude cerebral edema. They can cross or coexist with each other. Chronic mountain sickness, also known as Monch disease, is rare.
It mainly happens to people who live on the plateau for a long time or a few people who live above 4000 meters above sea level. There are four clinical types: chronic altitude sickness, altitude polycythemia, altitude blood pressure change and altitude heart disease. Acute and chronic altitude sickness is the lightest of acute and chronic altitude sickness.
1, acute altitude sickness (acute altitude sickness)
Very common. The maladjusted person starts to get sick 6-24 hours after entering the plateau area one day, and has symptoms such as bilateral forehead pain, palpitation, chest tightness, shortness of breath, anorexia, nausea and vomiting. The symptoms of the central nervous system are similar to those of drinking too much.
Some cases have cyanosis of lips and nail bed. Usually, after staying at the plateau for 24 ~ 48 hours, the symptoms are relieved and disappear after a few days. A few may develop into high altitude pulmonary edema and/or high altitude cerebral edema.
(1) Quickly enter the plateau above 3000 meters above sea level from the plain, or enter a higher altitude area from the plateau, and the onset occurs within a few hours or 1 ~ 3 days.
(2) One or more of the following performances should be considered:
① Symptoms such as headache, dizziness, nausea and vomiting, palpitation, shortness of breath, chest tightness and chest pain, insomnia, lethargy, anorexia, abdominal distension, numbness of hands and feet. After examination, it cannot be explained by other reasons. The evaluation of symptoms mainly depends on the degree of headache and/or vomiting (mild, moderate and severe), combined with other symptoms.
② Only mild symptoms such as palpitation, shortness of breath, chest tightness and chest pain. It is manifested during rest, but the symptoms are especially obvious after exercise.
③ Those with the following signs, such as obviously increased pulse, slight or moderate increase (also low) of blood pressure, cyanosis of lips and/or fingers, edema of eyelids or face, etc.
(3) After oxygen inhalation, or adapting to 1 ~ 2 weeks, or moving to a lower place, the above symptoms or signs are obviously alleviated or disappeared.
2. Chronic altitude sickness.
Symptoms of acute altitude sickness last for more than 3 months, which are manifested as headache, dizziness, insomnia, hypomnesis, inattention, palpitation, shortness of breath, anorexia, indigestion, numbness of hands and feet, facial edema, and sometimes arrhythmia or transient fainting.
