“Heatstroke”  when the body temperature is suddenly high.


Heatstroke is a condition caused by the body to overheat, often caused by work, labor, or strenuous exercise in a high temperature environment. It usually occurs when the body temperature reaches 40 degrees Celsius or more and it usually occurs during the summer or in areas with high humidity. It can cause damage to vital organs such as the brain, heart, lungs, kidneys and muscles. If not receiving the correct treatment promptly Will have a chance of dangerous complications Some of them were disabled and even died.

Heatstroke, what are the causes?

Duangporn Ruthiroko, MD, MD, MD and neurologist and neurologist Bangkok International Hospital said heat stroke or heat emergencies (Heatstroke) were divided into two broad categories. According to the causes that it causes are

– Classic heatstroke or Non-exertional heatstroke is caused by being in a high temperature environment that causes body temperature to rise accordingly. It is most often seen in people who live in hot and humid areas for a long time.

– Exertional heatstroke: In this case, body temperature rises from work or intense exercise in high temperature areas more easily in people unfamiliar with hot weather.

In addition, there are risk factors that make it easier for some people to develop heat stroke, such as being too young or too old. Have medical conditions such as heart disease, lung disease, obesity, rarely exercise. The use of certain drugs that cause the loss of water. Or the body is unable to fully respond to a higher body temperature Including drinking alcohol It is a common cause of abnormal body temperature regulation mechanisms that can also cause heat stroke. Or exposing the body to a sudden rise in temperature, such as when traveling in a hot country or during heat waves wave) The body is not able to adapt easily and can easily cause heat strokes.

Symptoms of heat stroke or heat stroke

The symptoms of heat stroke patients have a body temperature of 40 degrees Celsius or more. Together with the altered consciousness, symptoms of confusion, agitation, delirium, seizures or loss of consciousness may occur. Fast heartbeat Increased respiratory rate Some patients will have a headache. Nausea and vomiting Red skin. The doctor will diagnose the disease by knowing the history of the patient’s cause or risk factors for this condition. Physical examination reveals that the body temperature is elevated, along with the symptoms of various systems.

Some cases may be diagnosed with blood tests and X-rays to look for complications of heat stroke. In some patients with existing neurological diseases and disorders When exposed to high temperatures for a long time Or having a condition where the body temperature becomes extremely high may cause a relapse in neurological symptoms such as multiple sclerosis or epilepsy. disease

Danger of heat stroke or heat stroke

Dr. Phawit Lueang, MD, M.D., in the field of neurosurgery therapy Bangkok International Hospital It adds that heat stroke, or heat stroke, is different from a stroke (stroke), is a neurological emergency caused by ischemic stroke / blockage or rupture that often causes weakness, numbness, trouble speaking, and mouth. An aberration or abnormal posture requires urgent treatment. But there will be a different approach to diagnosis and treatment from heat stroke. This can cause a number of complications, depending on how long the body has hypothermia.

If not treated promptly, it can cause adverse effects on vital organs. Until death, such as brain disease, there is a chance that causes seizures, brain swelling, and permanent damage to brain cells. May cause muscle breakdown (Rhabdomyolysis) can affect the acute renal failure. The depletion of fluid leads to a decrease in the blood supply to the liver, which can lead to liver failure, an increase in the work of the heart, which can lead to an arrhythmia and a heart attack. May cause respiratory crisis (Acute respiratory distress syndrome). May cause bleeding easily. Or a blood clot in the body

How to prevent heat stroke or heat stroke?

Doctors suggest an initial response can be done by lowering the body temperature.

– Bring the patient to stay in the shade Or in an air-conditioned place with a cooler temperature

– Remove any clothing and clothing that is too tight to make the patient feel comfortable.

– May wipe the body with a cloth dampened in cold water. Or use an ice pack on the head, neck, armpits and groin Or may use a cold water spray

– It is strictly forbidden to drink sugary drinks or alcoholic beverages. This is because this drink loses its ability to regulate body temperature. Including drinking cold water Immediately, it can cause gastric spasms.

The heat stroke conditions can be prevented as follows: Easy to wear breathable clothing. If you know you’re going to be in hot weather, you can protect yourself from the sun by wearing sunglasses or a hat, and using sunscreen with an SPF of 15 or higher. Drink enough water. Avoid strenuous exercise in a place that is hot and uncomfortable. If a patient is found to be suspected of having symptoms that fall within the scope of the disease. You should contact the emergency medical institution or nearby hospital for help.
