Hypothermia is the cause of at least 1,500 deaths a year in the United States. [2] It is more common in older people and males. [ 5 ] One of the lowest documented body temperatures from which someone with accidental hypothermia has survived is 12.7 °C (54.9 °F) in a 2-year-old boy from Poland named Adam. [ 6 ]
One of the major symptoms of Shapiro syndrome is the hypothermia. Clonidine , an alpha 2-adrenoreceptor agonist, is a medication commonly used for hypertension. However, clonidine has been found to aid in hypothalamic regulation and is the most effective medication for symptom management in Shapiro syndrome . [ 5 ]
[1] [2] Patients observe these symptoms and seek medical advice from healthcare professionals. Because most people are not diagnostically trained or knowledgeable, they typically describe their symptoms in layman's terms, rather than using specific medical terminology. This list is not exhaustive.
Brutally cold weather is affecting large swaths of the United States, with about 80% of the population experiencing temperatures below freezing.
Causes: Exposure to cold temperatures [6] Risk factors: Military occupation, recreational winter activities, homelessness, inadequate or wet clothing, substance abuse, diabetes, peripheral vascular disease [6] [7] Diagnostic method: Based on symptoms [1] [6] Differential diagnosis: Hypothermia, Raynaud's phenomenon, chilblains (pernio), cold ...
In hypothermia, body temperature drops below that required for normal metabolism and bodily functions. In humans, this is usually due to excessive exposure to cold air or water, but it can be deliberately induced as a medical treatment. Symptoms usually appear when the body's core temperature drops by 1–2 °C (1.8–3.6 °F) below normal ...
Sufficient stress from extreme external temperature may cause injury or death if it exceeds the ability of the body to thermoregulate. Hypothermia can set in when the core temperature drops to 35 °C (95 °F). [2] Hyperthermia can set in when the core body temperature rises above 37.5–38.3 °C (99.5–100.9 °F).
The cold water can cause heart attack due to severe vasoconstriction, [2] where the heart has to work harder to pump the same volume of blood throughout the arteries. For people with pre-existing cardiovascular disease , the additional workload can result in myocardial infarction and/or acute heart failure , which ultimately may lead to a ...
