Common Causes
Alkalosis occurs when your body has too many bases. It can occur due to decreased blood levels of carbon dioxide, which is an acid. It can also occur due to increased blood levels of bicarbonate, which is a base. This condition may also be related to other underlying health issues such as low potassium, or hypokalemia.
Related Conditions
Alkalosis is a condition in which the body fluids have excess base (alkali). This is the opposite of excess acid (acidosis). ... Metabolic alkalosis is caused by too much bicarbonate in the blood.
What causes alkalosis?
There are two kinds of metabolic alkalosis: Chloride-responsive alkalosis results from loss of hydrogen ions, usually by vomiting or dehydration. Chloride-resistant alkalosis results when your body retains too many bicarbonate (alkaline) ions, or when there’s a shift of hydrogen ions from your blood to your cells.
What is the difference between acid and alkalosis?
Metabolic alkalosis can have central nervous system manifestations ranging from confusion to coma, peripheral neuropathic symptoms of tremor, tingling and numbness, muscle weakness and twitching, and arrhythmias, particularly when associated with hypokalemia and hypocalcemia.[16]
What are the two types of metabolic alkalosis?
What are the central nervous system symptoms of metabolic alkalosis?
What is systematic alkalosis?
The kidneys and lungs maintain the proper balance (proper pH level) of chemicals called acids and bases in the body. Decreased carbon dioxide (an acid) level or increased bicarbonate (a base) level makes the body too alkaline, a condition called alkalosis.
What happens to the body during alkalosis?
In metabolic alkalosis there is excess of bicarbonate in the body fluids. It can occur in a variety of conditions. It may be due to digestive issues, like repeated vomiting, that disrupt the blood's acid-base balance. It can also be due to complications of conditions affecting the heart, liver and kidneys.
What is alkalosis and what causes it?
Alkalosis is excessive blood alkalinity caused by an overabundance of bicarbonate in the blood or a loss of acid from the blood (metabolic alkalosis), or by a low level of carbon dioxide in the blood that results from rapid or deep breathing (respiratory alkalosis).
What are the types of alkalosis?
There are four main types of alkalosis.Respiratory alkalosis. Respiratory alkalosis occurs when there isn't enough carbon dioxide in your bloodstream. ... Metabolic alkalosis. Metabolic alkalosis develops when your body loses too much acid or gains too much base. ... Hypochloremic alkalosis. ... Hypokalemic alkalosis.
Is alkalosis serious?
In general, alkalosis is less life-threatening than acidosis, but severe electrolyte derangements can accompany alkalosis due to transcellular shifts, potentially resulting in rare but severe clinical disorders.
What is the most common cause of metabolic alkalosis?
The most common causes of metabolic alkalosis are the use of diuretics and the external loss of gastric secretions.
How do you treat alkalosis?
Metabolic alkalosis is corrected with the aldosterone antagonist spironolactone or with other potassium-sparing diuretics (eg, amiloride, triamterene). If the cause of primary hyperaldosteronism is an adrenal adenoma or carcinoma, surgical removal of the tumor should correct the alkalosis.
What diseases cause metabolic alkalosis?
Five inherited diseases that can cause metabolic alkalosis are:Bartter syndrome.Gitelman syndrome.Liddle syndrome.glucocorticoid remediable aldosteronism.apparent mineralocorticoid excess.
Can metabolic alkalosis cause death?
The mortality associated with severe metabolic alkalosis is substantial; a mortality rate of 45% in patients with an arterial blood pH of 7.55 and 80% when the pH was greater than 7.65 has been reported (2).
How does the body respond to respiratory alkalosis?
The kidney compensates in response to respiratory alkalosis by reducing the amount of new HCO3− generated and by excreting HCO3−. The process of renal compensation occurs within 24 to 48 hours. The stimulus for the renal compensatory mechanism is not pH, but rather Pco2.
How does the body compensate for metabolic alkalosis?
Your body compensates for both alkalosis and acidosis mainly through your lungs. The lungs change the alkalinity of your blood by allowing more or less carbon dioxide to escape as you breathe. The kidneys also play a role by controlling the elimination of bicarbonate ions.
How does alkalosis affect potassium?
A frequently cited mechanism for these findings is that acidosis causes potassium to move from cells to extracellular fluid (plasma) in exchange for hydrogen ions, and alkalosis causes the reverse movement of potassium and hydrogen ions.
Does metabolic alkalosis cause hyperventilation?
People who experience intense bouts of stress, anxiety, panic or anger are at higher risk for respiratory alkalosis. These conditions can lead to rapid, uncontrolled breathing (hyperventilation).
What is alkalosis in the body?
Alkalosis is an abnormal pathophysiological condition characterized by the buildup of excess base or alkali in the body . It results in an abnormally high serum pH (arterial pH greater than 7.45), which is termed alkalemia and forms one end of the spectrum of acid-base disorders. There is generally a loss of hydrogen ions (H) or an excess of bicarbonate ions (OH), and multiple factors can cause either of these. In general, alkalosis is less life-threatening than acidosis, but severe electrolyte derangements can accompany alkalosis due to transcellular shifts, potentially resulting in rare but severe clinical disorders. Alkalosis can be either respiratory or metabolic in origin, but metabolic alkalosis is far more common than respiratory causes. This activity reviews the evaluation and management of alkalosis and highlights the interprofessional team's role in improving care for patients with alkalosis.
How to treat alkalosis?
Specific etiologies like pyloric stenosis need surgical correction, while excessive ingestion of alkali will respond to restriction of excess intake. Alkalosis associated with conditions of excess aldosterone may need hormonal correction or replacement along with the treatment of associated hypertension. Correction of chloride responsive alkalosis caused by volume depletion is possible by replenishment of extracellular volume. Electrolyte disturbances associated with alkalosis such as hypokalemia and hypocalcemia are the chief causes of clinical deterioration in the patient and must undergo correction before the onset of life-threatening complications. Slow acid administration or dialysis with low bicarbonate baths may be necessary for emergent situations. [21]
What is the name of the condition where the body loses hydrogen ions?
Alkalosis is an abnormal pathophysiological condition characterized by the buildup of excess base or alkali in the body. It results in an abnormally high serum pH (arterial pH greater than 7.45), which is termed alkalemia and forms one end of the spectrum of acid-base disorders. There is generally a loss of hydrogen ions (H) or an excess of bicarbonate ions (OH), and multiple factors can cause either of these. In general, alkalosis is less life-threatening than acidosis, but severe electrolyte derangements can accompany alkalosis due to transcellular shifts, potentially resulting in rare but severe clinical disorders. Alkalosis can be either respiratory or metabolic in origin, but metabolic alkalosis is far more common than respiratory causes.[1]
How to treat respiratory alkalosis?
Treatment of respiratory alkalosis primarily targets correcting the hyperventilation (primary or iatrogenic), and apart from anxiety and pain treatment, it sometimes also requires adjustment of mechanical ventilation with intentional hypercapnia. [18]
What causes bicarbonate to be in the extracellular compartment?
Increased bicarbonate in the extracellular compartment—this occurs due to excess enteral intake of bicarbonate or alkali (milk-alkali syndrome) or increased parenteral intake of citrate or acetate. Increased renal reabsorption of bicarbonate can also cause metabolic alkalosis (severe hypokalemia, primary hyperaldosteronism, Cushing syndrome, Bartter syndrome, Gitelman syndrome, toxic ingestion of licorice, excessive chloruretic diuretic use). [4][5][6][7]
How does the kidney maintain acid-base balance?
The kidney attempts to maintain normal acid-base balance by the dual mechanisms of bicarbonate reabsorption, mainly in the proximal tubule, and bicarbonate production in the distal nephron. Reabsorption of bicarbonate is mediated by a Na-H (sodium-hydrogen) antiporter and also by the H (+)-ATPase (adenosine triphosphate-ase). Influences on bicarbonate reabsorption include effective arterial blood volume, glomerular filtration rate, chloride, and potassium concentrations in the serum. In conditions resulting in respiratory alkalosis, the kidney acts to both decrease bicarbonate reabsorption and bicarbonate production as a compensatory mechanism. This process helps maintain the pH of the extracellular compartment to neutralize the effect of the low pCO2 that is the primary derangement of respiratory alkalosis. However, the kidneys' complex buffering mechanisms may take several days to achieve full effect, with an eventual expected fall of bicarbonate by 4 to 5 mmol/L for every 10 mmHg fall in pCO2.
What causes increased bicarbonate absorption?
Diuretic-induced alkalosis—diuretics (loop and thiazide) that block sodium and chloride reabsorption can cause increased bicarbonate absorption at the proximal tubule leading to increased serum bicarbonate concentration, also called contraction alkalosis.

Why does respiratory alkalosis occur?
Respiratory alkalosis is caused due to hyperventilation, which is rapid and deep breathing that causes an excessive amount of carbon dioxide to be discharged from your bloodstream.
What is the condition where the body does not possess the necessary amount of potassium?
Hypokalemic alkalosis. This condition develops when your body does not possess the necessary amount of [11] potassium. Potassium is usually gained by consuming potassium-rich foods. Failing to consume the proper amount of potassium-rich foods can cause potassium deficiency.
How to treat respiratory alkalosis?
In case of respiratory alkalosis caused by [20] hyperventilation, the treatment method advised is to breathing into a paper bag. By doing so, your body can retain more carbon dioxide and thereby improve the condition. If there is a lack of oxygen, the same process is advised. But in severe cases, you will need to get oxygen through an oxygen mask.
What is the name of the condition where the body has an excess of alkali?
Alkalosis: Symptoms, Types, Causes & Prevention. Alkalosis [1] is a condition developed from a reduction in the hydrogen ion concentration of the arterial blood plasma. Basically, it arises when the body fluids have an excess of alkali or too many bases.

What causes alkaline bicarbonate ions to deplete?
Heart, kidney, or liver failure. Metabolic alkalosis can be caused by failure of a major organ, such as your heart, kidney, or liver. This leads to potassium depletion.
How do kidneys help with alkalosis?
The kidneys can help combat alkalosis by increasing the excretion of bicarbonate ions through the urine. This is also an automatic process, but it’s slower than respiratory compensation.
How does the body compensate for alkalosis?
Your body compensates for both alkalosis and acidosis mainly through your lungs. The lungs change the alkalinity of your blood by allowing more or less carbon dioxide to escape as you breathe. The kidneys also play a role by controlling the elimination of bicarbonate ions.

What is the scale used to measure acidity?
The acidity or alkalinity of a liquid is measured on a scale called pH. In metabolic alkalosis, the pH of your blood is high.
Why does alkalosis occur?
Your body is continuously working to maintain the blood’s acid-base (alkali) balance. Alkalosis occurs when there’s too much alkali and not enough acid. Chemical changes in the acid-base balance can reflect changes in metabolism or breathing.
What is respiratory alkalosis?
Respiratory alkalosis occurs when high levels of carbon dioxide disrupt the blood’s acid-base balance. It often occurs in people who experience rapid, uncontrollable breathing (hyperventilation). Treatment includes supplemental oxygen and therapies to reduce the risk of hyperventilation.
Why is respiratory alkalosis important?
The condition is not life-threatening. Nor does it have lingering effects on your health. But it’s important to seek medical care for respiratory alkalosis because it’s often a sign of another medical condition. Some people need treatment with supplemental oxygen. Addressing what’s causing you to hyperventilate lowers your risk of future episodes.
Can a symtom affect any organ system?
The symptoms can affect any organ system in the body. You may experience:
How to treat metabolic alkalosis?
Treatment of metabolic alkalosis is targeted at treating the underlying pathology. In anxious patients, anxiolytics may be necessary. In infectious disease, antibiotics targeting sputum or blood cultures are appropriate. In embolic disease, anticoagulation is necessary. Ventilator support may be necessary for patients with acute respiratory failure, acute asthma, or acute, chronic obstructive pulmonary disease (COPD) exacerbation if they show signs of respiratory fatigue. In ventilator controlled patients, it may be necessary to reevaluate their ventilator settings to reduce respiratory rate. If hyperventilation is intentional, monitor the arterial or venous blood gas values closely. In severe cases, pH may be directly reduced using acidic agents. However, this is not routinely done. [14][15][16]
What causes respiratory alkalosis?
These include central causes, hypoxemic causes, pulmonary causes, and iatrogenic causes. Central sources are a head injury, stroke, hyperthyroidism, anxiety-hyperventilation, pain, fear, stress, drugs, medications such as salicylates, and various toxins. Hypoxic stimulation leads to hyperventilation in an attempt to correct hypoxia at the expense of a CO2 loss. Pulmonary causes include pulmonary embolisms, pneumothorax, pneumonia, and acute asthma or COPD exacerbations. Iatrogenic causes are primarily due to hyperventilation in intubated patients on mechanical ventilation. [6][7]
How does HCO3 affect alkalosis?
HCO3 functions as an alkalotic substance. CO2 (carbon dioxide) functions as an acidic substance. Therefore, Increases in HCO3 (bicarbonate) or decreases in CO2 will make blood more alkalotic . The opposite is also true where decreases in HCO3 or an increase in CO2 will make blood more acidic. CO2 levels are physiologically regulated by the pulmonary system through respiration, whereas the HCO3 levels are regulated through the renal system with reabsorption rates. Therefore, respiratory alkalosis is a decrease in serum CO2. While it is theoretically possible to have decreased CO2 production, in every scenario this illness is a result of hyperventilation where CO2 is breathed away. [2][3][4]
What is the normal pH of the blood?
Respiratory alkalosis is 1 of the 4 basic classifications of blood pH imbalances. Normal human physiological pH is 7.35 to 7.45. A decrease in pH below this range is acidosis, an increase above this range is alkalosis. Respiratory alkalosis is by definition a disease state where the body’s pH is elevated to greater than 7.45 secondary to some respiratory or pulmonary process.[1]
What is the primary pH buffer system in the human body?
The primary pH buffer system in the human body is the HCO3/CO2 chemical equilibrium system. Where:
Is respiratory alkalosis an acute or chronic process?
Respiratory alkalosis may be an acute process or a chronic process. These are determined based on the level of metabolic compensation for the respiratory disease. Excess HCO3 levels are buffered to reduce levels and maintain a physiological pH through the renal decrease of H secretion and increasing HCO3 secretion; however, this metabolic process occurs over the course of days whereas respiratory disease can adjust CO2 levels in minutes to hours. Therefore, acute respiratory alkalosis is associated with high bicarbonate levels since there has not been sufficient time to lower the HCO3 levels and chronic respiratory alkalosis is associated with low to normal HCO3 levels. [8][1][9]
Is respiratory alkalosis a disease?
Respiratory alkalosis is the most common acid-base abnormality with no discrimination between genders. The exact frequency and distribution of disease are dependent upon the etiology. Likewise, the morbidity and mortality rates are dependent on the etiology of the disease. [5]
What is the name of the book that states that alkalosis can cause seizures?
Arthur Greenberg and Alfred K. Cheung's "Primer on Kidney Diseases" states that alkalosis may also cause a predisposition to seizures, and Cichoke's book adds that severe cases can also put victims in a state of shock and could cause death.
Can vomiting cause alkalosis?
Interestingly, prolonged vomiting can also cause alkalosis, according to the National Institutes of Health. Such instances are specified as hypochloremic alkalosis, brought on by extremely low levels of chloride due to the loss of stomach liquids and other contents. Advertisement.
Can alkalosis cause confusion?
The National Institutes of Health reports light-headedness as a common alkalosis symptom, as well as confusion. In extreme cases, such symptoms can worsen to the level of catatonic stupor and even coma. Arthur Greenberg and Alfred K. Cheung's "Primer on Kidney Diseases" states that alkalosis may also cause a predisposition to seizures, and Cichoke's book adds that severe cases can also put victims in a state of shock and could cause death. These symptoms, taken together, are very similar to the range of symptoms caused by hypocalcemia, and in isolated cases the milder symptoms could suggest dozens of different health issues. To be sure that the cause of one or more of these symptoms is an elevated level of alkalinity, blood tests administered by a physician are required.
