Approach to hypohidrosis
Summary
Hypohidrosis, or diminished sweating, can lead to dangerous hyperthermia. Identifying the cause, whether exogenous, dermatological, or neurological, is key to treatment and avoiding heat-related illness.
Area of Science:
- Medical Science
- Dermatology
- Neurology
Background:
- Hypohidrosis is diminished sweating, potentially causing hyperthermia, heat exhaustion, and death.
- Causes are categorized as exogenous, dermatological, or neurological, each with distinct mechanisms and presentations.
Purpose of the Study:
- To outline the etiological classification of hypohidrosis.
- To detail diagnostic approaches based on clinical presentation and examination findings.
- To summarize treatment strategies for hypohidrosis and related conditions.
Main Methods:
- Systematic review of hypohidrosis etiology and diagnostic workup.
- Classification of neurological causes into upper and lower motor neuron patterns.
- Guidance on physical examination, skin biopsy, neuroimaging, and specialized autonomic function tests.
Main Results:
- Exogenous causes involve systemic inhibition or local damage.
- Dermatological causes include congenital or acquired disorders.
- Neurological causes are differentiated by upper (spasticity) or lower (flaccidity) motor neuron signs.
Conclusions:
- A systematic approach, excluding exogenous causes first, is crucial for diagnosing hypohidrosis.
- Physical examination and targeted investigations guide etiological determination.
- Treatment focuses on the underlying cause and environmental control; corticosteroids benefit acquired idiopathic generalized anhidrosis.

01:22Methods of reducing fever
The signs and symptoms of fever include hot and dry skin, flushed face, thirst, muscle aches, anorexia, headache, tachycardia, tachypnea, and fatigue. Elevated body temperature is reduced using two methods: pharmacological and nonpharmacological. Proper identification and treatment of the root cause of a fever is of utmost importance.

01:29Decreased Body Temperature
A decreased body temperature can occur in patients with hypothermia and frostbite. Heat loss with extended cold exposure overpowers the body's ability to create heat, resulting in hypothermia. Core temperature readings help classify hypothermia. Mild hypothermia is temperatures between 32 °C (89.6 °F) and 35°C (95 °F) and is caused by impaired thermoregulation. Moderate hypothermia is temperatures between 28 C (82.4 °F) and 32 °C (89.6 °F) caused by sustained extreme cold exposure, and severe...
01:26Thermoregulation
The human body has a sophisticated thermoregulation system that employs negative feedback mechanisms to maintain an optimal core temperature. When the core temperature drops, peripheral and central thermoreceptors send signals to the hypothalamus, activating the heat-promoting center. This center triggers several responses aimed at increasing the core temperature. First, vasoconstriction reduces the flow of warm blood from internal organs to the skin so that the heat is not lost from the skin,...
01:20Accessory Structures of the Skin: Sweat Glands
Sweat glands or sudoriferous glands are one of the important accessory structures of the skin. They are small, coiled tubular structures located in the dermis, the middle layer of the skin. Sweat glands are responsible for producing and secreting sweat, a watery fluid that helps regulate body temperature and excrete waste products.
Sweat glands are classified as merocrine glands; that is, the secretions are excreted by exocytosis through a duct without affecting the cells of the gland. There...

01:25Hyperpnea and Hyperventilation
Hyperventilation refers to a higher-than-normal rate and depth of breathing, often associated with anxiety attacks. This excessive breathing surpasses the body's need to expel CO2, leading to a condition known as hypocapnia - an unusually low level of carbon dioxide in the blood. Hypocapnia can constrict cerebral blood vessels, reducing blood flow to the brain, which may result in dizziness or fainting. Early signs include tingling and muscle spasms in the hands and face, caused by falling...
01:25Body Temperature
The body's temperature, measured in degrees, is determined by the balance between heat production and dissipation to the surrounding environment. For instance, if exercising vigorously, the body will produce more heat, causing sweat and dissipating that heat. Despite extreme environmental conditions and physical exertion, the human temperature-control system maintains a constant core body temperature (the temperature of deep tissues, which are the tissues located beneath the skin and other...
