Metabolic Acidosis. Definition Metabolic acidosis is a condition in which there is too much acid in the body fluids.

Alternative Names Acidosis - metabolic Causes Metabolic acidosis develops when too much acid is produced in the body. There are several types of metabolic acidosis: Diabetic acidosis also called diabetic ketoacidosis and DKA develops when substances called ketone bodies which are acidic build up during uncontrolled diabetes.

Hyperchloremic acidosis is caused by the loss of too much sodium bicarbonate from the body, which can happen with severe diarrhea. Most symptoms are caused by the underlying disease or condition that is causing the metabolic acidosis. Metabolic acidosis itself most often causes rapid breathing. Acting confused or very tired may also occur.

Severe metabolic acidosis can lead to shock or death. In some situations, metabolic acidosis can be a mild, ongoing chronic condition. These tests can help diagnose acidosis. They can also determine whether the cause is a breathing problem or a metabolic problem.

Tests may include:. Treatment is aimed at the health problem causing the acidosis. In some cases, sodium bicarbonate the chemical in baking soda may be given to reduce the acidity of the blood. Often, you will receive lots of fluids through your vein.

Diabetic ketoacidosis can be prevented by keeping type 1 diabetes under control. It keeps our blood from becoming too acidic. Healthy kidneys help keep your bicarbonate levels in balance. A small group of studies have shown that treatment with sodium bicarbonate or sodium citrate pills can help keep kidney disease from getting worse. However, you should not take sodium bicarbonate or sodium citrate pills unless your healthcare provider recommends it.

Diet : Increasing fruit and vegetable intake may decrease acid load in the body. This is because fruits and vegetables produce alkali, whereas foods such as meats, eggs, cheese, and cereal grains cause the body to make acid. Your kidney dietitian can show you how to safely increase the right type and amounts of fruits and vegetables in your diet based on your stage of kidney disease.

The most characteristic sign is hyperpnea long, deep breaths at a normal rate , reflecting a compensatory increase in alveolar ventilation; this hyperpnea is not accompanied by a feeling of dyspnea. Severe, acute acidemia predisposes to cardiac dysfunction with hypotension and shock Shock Shock is a state of organ hypoperfusion with resultant cellular dysfunction and death.

Mechanisms may involve decreased circulating volume, decreased cardiac output, and vasodilation, sometimes Chronic acidemia causes bone demineralization disorders eg, rickets, osteomalacia Vitamin D Deficiency and Dependency Inadequate exposure to sunlight predisposes to vitamin D deficiency.

Deficiency impairs bone mineralization, causing rickets in children and osteomalacia in adults and possibly contributing Determining the cause of metabolic acidosis begins with the anion gap. The cause of an elevated anion gap may be clinically obvious eg, hypovolemic shock, missed hemodialysis , but if not, blood testing should include.

Salicylate levels can be measured in most laboratories, but methanol and ethylene glycol frequently cannot; their presence may be suggested by presence of an osmolar gap. Although ingestion of ethanol may cause an osmolar gap and a mild acidosis, it should never be considered the sole cause of a significant metabolic acidosis.

Common causes Sodium bicarbonate NaHCO 3 primarily for severe acidemia—give with caution. Treatment is directed at the cause. Treatment of acidemia with sodium bicarbonate NaHCO 3 is clearly indicated only in certain circumstances and is probably deleterious in others. However, when acidosis results from organic acid accumulation ie, high anion gap acidosis , bicarbonate therapy is controversial; it does not clearly decrease mortality in these conditions, and there are several possible risks.

In any condition, sodium bicarbonate may also cause sodium and volume overload, hypokalemia, and, by inhibiting respiratory drive, hypercapnia. Despite these and other controversies, most experts still recommend giving bicarbonate IV for severe metabolic acidosis pH 7. Treatment requires 2 calculations same for both conventional and SI units.

The amount of sodium bicarbonate needed to achieve that level is. For example, a kg man has severe metabolic acidosis with a pH of 6. The target bicarbonate level needed to achieve a pH of 7. To increase bicarbonate by 4, multiply 4 by 0.
