Metabolic acidosis is a condition in which there is too much acid in the body fluids.
Alternative NamesAcidosis - metabolic
Causes, incidence, and risk factorsMetabolic acidosis occurs when the body produces too much acid, or when the kidneys are not removing enough acid from the body. There are several types of metablic acidosis:
- Diabetic acidosis (also called diabetic ketoacidosis and DKA) develops when substances known as ketone bodies, which are acidic, build up during uncontrolled diabetes
- Hyperchloremic acidosis results from excessive loss of sodium bicarbonate from the body, as can happen with severe diarrhea
- Lactic acidosis is a buildup of lactic acid. It can be caused by:
- Alcohol
- Cancer
- Exercising for a very long time
- Liver failure
- Low blood sugar (hypoglycemia)
- Medications such as salicylates
- Prolonged lack of oxygen from shock, heart failure, or severe anemia
- Seizures
Other causes of metabolic acidosis include:
- Kidney disease(distal tubular acidosis and proximal renal tubular acidosis)
- Poisoning by aspirin, ethylene glycol (found in antifreeze), or methanol
- Severe dehydration
Most symptoms are caused by the underlying disease or condition that is causing the metabolic acidosis. Metabolic acidosis itself usually causes rapid breathing. Confusion or lethargy may also occur. Severe metabolic acidosis can lead to shock or death. In some situations, metabolic acidosis can be a mild, chronic (ongoing) condition.
Signs and tests- Arterial blood gas
- Serum electrolytes
- Urine pH
Arterial blood gas analysis or a serum electrolytes test (such as a basic metabolic panel) will confirm acidosis is present and determine whether it is respiratory acidosis or metabolic acidosis.
Other test may be needed to determine the cause of the acidosis.
TreatmentTreatment is aimed at the underlying condition. In certain circumstances, sodium bicarbonate (baking soda) may be given to improve the acidity of the blood.
Expectations (prognosis)What can be expected will depend on the underlying disease causing the metabolic acidosis.
ComplicationsWhen very severe, metabolic acidosis can lead to shock or death.
Calling your health care providerSeek medical treatment if you develop symptoms of any disease that can cause metabolic acidosis.
PreventionKeeping type 1 diabetes under control may help prevent diabetic ketoacidosis, one type of metabolic acidosis.

Metabolic acidosis is a condition characterized by an imbalance in the body's acid-base equilibrium, leading to an accumulation of acid or loss of bicarbonate in the blood. This can be caused by conditions such as kidney disease, Diabetes, or ingestion of toxic substances. Symptoms may include rapid breathing, confusion, and fatigue. Treatment aims to address the underlying cause and restore the body's acid-base balance.

What is a base excess?
Base excess is a measure of the amount of excess or deficit of bicarbonate in the blood, which helps indicate the presence of metabolic acidosis or alkalosis. It is calculated by measuring the pH and levels of carbon dioxide and bicarbonate in the blood. Negative values indicate metabolic acidosis, while positive values suggest metabolic alkalosis.
Is Acidosis defined as a blood pH less than normal?
Yes, acidosis is defined as a condition where the blood pH is lower than the normal range of 7.35 to 7.45. It occurs due to an excess of acid or a decrease in bicarbonate levels in the blood. Acidosis can be classified into respiratory acidosis and metabolic acidosis based on the underlying cause.
What is the most common cause of acid base imbalance?
The most common cause of acid-base imbalance is respiratory alkalosis or acidosis, often due to hyperventilation or respiratory failure. Metabolic acidosis or alkalosis can also occur from conditions such as renal failure, diabetes, or dehydration.
Acidosis?
Acidosis is a condition characterized by an increase in acidity levels in the blood and body tissues. It can be caused by conditions such as diabetes, kidney disease, or lung diseases. Symptoms may include fatigue, confusion, rapid breathing, and nausea. Treatment often involves addressing the underlying cause and may include the use of medications to restore the body's acid-base balance.
What is the most common cause of acid-base imbalance?
The most common cause of acid-base imbalance is respiratory acidosis or alkalosis, which occurs due to abnormal levels of carbon dioxide in the blood resulting from lung conditions such as COPD or asthma. Other common causes include metabolic acidosis or alkalosis, which result from kidney dysfunction or electrolyte imbalances.
What would cause metabolic alkalosis to slide into metabolic acidosis?
respiratory alkalosis would cause metabolic acidosis
What is the outcome of ketosis?
Metabolic acidosis
In metabolic alkalosis does the PO2 decreases?
The PO2 does decrease in metabolic acidosis, Similarly, there is a decrease in the pH and HCO3 levels. Metabolic acidosis is a condition where the body is producing too much acid.
Can vomiting cause Metabolic acidosis?
yes
A Patients with a bicarbonate deficit experience what?
metabolic acidosis
A person with nephritis will show symptoms of?
Metabolic acidosis
Examples of acidosis?
Acidosis is high levels of acidity in the blood and other body tissue, occuring when the arterial pH falls below 7.35. The two types of acidosis are metabolic acidosis and respiratory acidosis.
Causes of metabolic acidosis in burns?
Acidosis following thermal injury is common, and is most pronounced on admission. The acidosis is usually compensated by respiratory alkalosis. Acidosis develops within hours after > 30% burns. Has both metabolic and respiratory components. Former due to products of heat-damaged tissues and relative hypoxia.
List some other potential causes of metabolic acidosis?
Metabolic acidosis occurs when the body does not get rid of the build up of acids in the body. Acidosis can occur due to kidney failure, uncontrolled diabetes, alcohol poisoning, and prolonged lack of oxygen.
How to decipher metabolic acidosis from respiratory acidosis?
A metabolic acidosis will have a low HCO3(less than 22) and a low base access( less than-2) there may be a compensatory low CO2 (less than 4,7kPa. But in respiratory acidosis the CO2 is high( more than 6.0k,Pa) and the O2 may be low
What is the Medical term meaning decreased blood pH?
Usually, this acidity is caused by metabolism or respiration. Then it is called " respiratory acidosis" or "non-respiratory acidosis" (metabolic acidosis). These conditions might cause acidemia.
Does alcohol cause acidosis or alkalosis?
Alcohol can cause metabolic acidosis due to its influence on metabolism and disruption of the acid-base balance in the body. However, chronic alcohol use can also lead to conditions such as alcoholic ketoacidosis, which is a specific type of metabolic acidosis associated with excessive alcohol consumption.
