Metabolic acidosis is a serious electrolyte disorder characterized by an imbalance in the body's acid-base balance.Metabolic acidosis has three main root causes: increased acid production, loss of bicarbonate, and a reduced ability of the kidneys to excrete excess acids. [5]
In general, the cause of a hyperchloremic metabolic acidosis is a loss of base, either a gastrointestinal loss or a renal loss [citation needed]. Gastrointestinal loss of bicarbonate (HCO − 3) [citation needed] Severe diarrhea (vomiting will tend to cause hypochloraemic alkalosis) Pancreatic fistula with loss of bicarbonate rich pancreatic fluid
The most common symptoms include nausea, vomiting, abdominal pain, and weakness. [1] [2] Breath may also develop the smell of acetone as it is a volatile ketone that can be exhaled. Rapid deep breathing, or Kussmaul breathing, may be present to compensate for the metabolic acidosis. [1]
Metabolic acidosis is compensated for in the lungs, as increased exhalation of carbon dioxide promptly shifts the buffering equation to reduce metabolic acid. This is a result of stimulation to chemoreceptors , which increases alveolar ventilation , leading to respiratory compensation, otherwise known as Kussmaul breathing (a specific type of ...
Lactic acidosis can also be the result of illnesses, medications, poisonings or inborn errors of metabolism that interfere directly with oxygen utilization by cells. [1] The symptoms are generally attributable to the underlying cause, but may include nausea, vomiting, shortness of breath, and generalised weakness.
These abnormalities are caused by diarrhea, vomiting, increased sodium chloride intake, renal dysfunction, diuretic use, and diabetes. Hyperchloremia should not be mistaken for hyperchloremic metabolic acidosis as hyperchloremic metabolic acidosis is characterized by two major changes: a decrease in blood pH and bicarbonate levels, as well as ...
An anion-gap metabolic acidosis occurs later in the course of the overdose, especially if it is a moderate to severe overdose, due to the increase in protons (acidic contents) in the blood. The diagnosis of poisoning usually involves measurement of plasma salicylate, the active metabolite of aspirin, by automated spectrophotometric methods.
It can be associated with chronic respiratory acidosis. [2] If it occurs together with metabolic alkalosis (decreased blood acidity) it is often due to vomiting. It is usually the result of hyponatremia or elevated bicarbonate concentration. It occurs in cystic fibrosis. [citation needed]
