In the clinical case presented, the presence of metabolic alkalosis , characterized by an abnormal increase of the pH blood and a reduction in Hydrogen ions (H+) levels, resulting in a more alkaline environment in the body. This scenario is explained by the persistent occurrence of vomiting, which lead to excessive loss of hydrochloric acid (HCl) of the stomach and a proportional increase in bicarbonate (HCO3-) . with the bicarbonate buffer system to regulate the pH of the body. Hypoventilation, decreased respiratory rate, increases alveolar CO2 pressure and extracellular H2CO3 concentration, with consequent pH drop. Hypotrophy or Atrophy is characterized by quantitative decrease in cellular structural components, resulting in a reduction in their volume and in number. Generally, there is an increase in the degradation of cellular proteins during a physiological or pathological condition, as in the case here, malnutrition.
d) The hypernatremia is defined as a serum sodium concentration above 145 Meq/L (or 145 mmol/l). This clinical picture indicates a deficit of the total body water in relation to the total of sodium , usually caused by insufficient water intake in relation to loss . The process of eliminating these structures by activating the complement system and phagocytes. On the other hand, PSA tends to increase in situations of change in prostatic tissue, possibly by urinary tract infection or severe urinary retention, resulting in effort to urinate by the patient.
