When heating the body metabolic change?

When heating the body metabolic change?


When the fever, the body\'s metabolic activity enhancement, and mainly to increase catabolism. However fever metabolism enhancement and temperature rise in no proportional relationship. Temperature rise is not entirely as a result of heat production increases, and Thermogenesis increases of temperature rises degree does not necessarily parallel. In General, if the normal human body temperature (37 ° c) rise to 40 ° c, metabolism intensity must increase several times while heating to 40 ° c in children with metabolic increases the strength of less than two-fifths. And in normal human metabolism after the strong physical strength increased several times, but only small changes in body temperature. At different stages of fever and metabolic strength is constantly changing. Like fever increased, aerobic decomposition of metabolism is increased, while fever duration aerobic decomposition of sometimes rather low than heat upward. Some diseases, such as the invasion advanced tuberculosis, despite the low heat, but catabolism strength was a significant increase, so the patient weight faster. And if ileotyphus, due to serious metabolic disorder, aerobic decomposition can be below the normal level, while the cooling period is added. When the fever, because there is poison in the body, hunger, malnutrition and other factors, often incomplete oxidation in aerobic and anaerobic metabolism enhancing, for metabolic activity should not completely focused on metabolic activity of aerobic decomposition, aerobic metabolism of incomplete oxidation and anaerobic decomposition cannot be neglected.
  
Heating sugars, fats, proteins, vitamin metabolism changes what?

When a sudden high fever, increased due to pituitary adenomas, adrenocortical hormone secretion, and sympathetic-adrenal system strongly excited, making liver glycogen breakdown strengthened, the rise in blood sugar, or even urine occurs. However, when the temperature gradually increased, Hyperglycemia often not at all obvious. If weak, hunger, or chronic wasting disease are fever, elevated blood sugar not only, sometimes slightly lower.
When heating, aerobic and anaerobic Glycolysis of glucose are strengthened, aerobic Glycolysis accompanied by incomplete oxidation, it organizations, such as lactic acid, pyruvic acid in the blood and urine content increased, mild acidosis can occur in severe cases.
When infectious chronic low fever, glucose decomposition enhanced, adipose tissue decomposition and significantly increase patient physical thin, fat, fatty acids in the blood increase. And when such as high fever, excessive fat decomposition, and accompanied by incomplete oxidation, can produce intermediate metabolite accumulation, severe ketonemia and ketones in urine can appear.
When infectious fever, strengthening not only sugar, fat decomposition, protein decomposition also strengthened. First of all is the substantive organs of protein decomposition, such as liver, kidney, etc. Muscle proteins also have significant decomposition, proteins, plasma protein in gland are reduced. Due to increased protein decomposition, it is non-protein nitrogen in the blood rise, urea discharged see also increased. Together with the patient due to heat, appetite, reduced protein intake, digestive disorders, protein absorption is also reduced, thus a negative nitrogen balance. Therefore, the fever can cause low protein-energy malnutrition.
When the fever, due to other substances metabolism enhancing, consumption increases the vitamin, and digestive dysfunction due to heat, reducing intake of vitamin, so often lack of vitamins, first group b vitamins and vitamin c deficiency. So when when children with fever, is important to note that vitamin supplement.
  
Heating water electrolysis, quality of acid-base balance what has changed?


The increase in body temperature period duration and high fever, due to increased catabolism, accumulation of metabolites and the change of neural, humoral regulation function, electrolyte water retention within organizations, reduces the amount of urine. The cooling period, a lot of sweat and urine volume increased tissue retention of water and salt in a large number of discharges. Decomposition of fever because the Organization strengthening, so increasing potassium content in blood and urine, generation and discharge of phosphates are also strengthened.
When heating, due to incomplete oxidation, particularly fat and sugar and acid intermediate metabolites accumulate in the body and blood alkali reserve in reduced acidosis can occur.
