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]
Nervous system involvement may be seen with acidosis and occurs more often with respiratory acidosis than with metabolic acidosis. Signs and symptoms that may be seen in acidosis include headaches, confusion, feeling tired, tremors, sleepiness, flapping tremor, and dysfunction of the cerebrum of the brain which may progress to coma if there is ...
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]
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.
High anion gap metabolic acidosis is typically caused by acid produced by the body. More rarely, it may be caused by ingesting methanol or overdosing on aspirin . [ 1 ] [ 2 ] The delta ratio is a formula that can be used to assess elevated anion gap metabolic acidosis and to evaluate whether mixed acid base disorder (metabolic acidosis) is present.
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
After the first stage, gastrointestinal symptoms appear to resolve in the latent phase and individuals may show signs of improvement. [2] Following this stage, the iron begins to affect the cells of the body's organs which manifests as numerous systemic signs and symptoms developing after 6 to 72 hours, in the metabolic acidosis phase.
Adolf Kussmaul referred to breathing when metabolic acidosis was sufficiently severe for the respiratory rate to be normal or reduced. [2] This definition is also followed by several other sources, [3] [4] including for instance Merriam-Webster, which defines Kussmaul breathing as "abnormally slow deep respiration characteristic of air hunger and occurring especially in acidotic states".
