Thyroid storm is a severe form of thyrotoxicosis characterized by rapid and often irregular heart beat, high temperature, vomiting, diarrhea, and mental agitation. Symptoms may not be typical in the young, old, or pregnant. [2] It usually occurs due to untreated hyperthyroidism and can be provoked by infections. [2]
In humans, hyperthermia is defined as a temperature greater than 37.5–38.3 °C (99.5–100.9 °F), depending on the reference used, that occurs without a change in the body's temperature set point. [ 3][ 10] The normal human body temperature can be as high as 37.7 °C (99.9 °F) in the late afternoon. [ 2] Hyperthermia requires an elevation ...
The pathophysiology of hypertension is an area which attempts to explain mechanistically the causes of hypertension, which is a chronic disease characterized by elevation of blood pressure. Hypertension can be classified by cause as either essential (also known as primary or idiopathic) or secondary. About 90–95% of hypertension is essential ...
Euthyroid sick syndrome ( ESS) is a state of adaptation or dysregulation of thyrotropic feedback control [ 1] wherein the levels of T3 and/or T4 are abnormal, but the thyroid gland does not appear to be dysfunctional. This condition may result from allostatic responses of hypothalamus-pituitary-thyroid feedback control, dyshomeostatic disorders ...
The thyroid hormones cross the follicular cell membrane towards the blood vessels by an unknown mechanism. [31] Text books have stated that diffusion is the main means of transport, [ 35 ] but recent studies indicate that monocarboxylate transporter (MCT) 8 and 10 play major roles in the efflux of the thyroid hormones from the thyroid cells.
The difference between the systolic and diastolic pressures is known as pulse pressure, [1] while the average pressure during a cardiac cycle is known as mean arterial pressure. [2] Blood pressure is one of the vital signs—together with respiratory rate, heart rate, oxygen saturation, and body temperature—that healthcare professionals use ...
High blood pressure, or hypertension, is often referred to as the "silent killer," because it typically doesn't present many symptoms. So if people aren't getting regular checkups, they often don ...
e. Hypertension, also known as high blood pressure, is a long-term medical condition in which the blood pressure in the arteries is persistently elevated. [ 11] High blood pressure usually does not cause symptoms itself. [ 1] It is, however, a major risk factor for stroke, coronary artery disease, heart failure, atrial fibrillation, peripheral ...
