Other rare causes of hyperthermia include thyrotoxicosis and an adrenal gland tumor, called pheochromocytoma, both of which can cause increased heat production. [2] Damage to the central nervous system from brain hemorrhage, traumatic brain injury, status epilepticus, and other kinds of injury to the hypothalamus can also cause hyperthermia. [2]
Excess thyroid hormone, which is called thyrotoxicosis (such as in cases of hyperthyroidism), is the most common cause. [1] [2] Other causes include: Amphetamines along with other types of stimulant medications, such as appetite suppressants; Anticholinergics and other drugs that can impair sweating; Caffeine; Malignant hyperthermia ...
Heat illness is a spectrum of disorders due to increased body temperature. It can be caused by either environmental conditions or by exertion.It includes minor conditions such as heat cramps, heat syncope, and heat exhaustion as well as the more severe condition known as heat stroke. [1]
Essentially, dehydration may lead to hyperthermia because overheating can alter your body’s normal temperature. (See more about your body's response to heat and what happens when you sweat here.) 5.
Space heaters also have a hidden hazard: They can cause overheating — aka hyperthermia — especially in kids, people with disabilities and older adults who may have difficulty leaving a room ...
About 70% of perimenopausal women experience them and close to 80% of menopausal women get them as well, says Dr. Jewel Kling, associate director of women's health for Mayo Clinic in Arizona ...
Paroxysmal sympathetic hyperactivity (PSH) is a syndrome that causes episodes of increased activity of the sympathetic nervous system.Hyperactivity of the sympathetic nervous system can manifest as increased heart rate, increased respiration, increased blood pressure, diaphoresis, and hyperthermia. [1]
Malignant hyperthermia is diagnosed on clinical grounds, but various laboratory investigations may prove confirmatory. These include a raised creatine kinase level, elevated potassium, increased phosphate (leading to decreased calcium) and—if determined—raised myoglobin; this is the result of damage to muscle cells.
