Metabolic acidosis is a condition that occurs when the body produces excessive quantities of acid or when the kidneys are not removing enough acid from the body. Metabolic acidosis starts in the kidneys instead of the lungs. It occurs when they can’t eliminate enough acid or when they get rid of too much base. Diabetic acidosis occurs in people with diabetes that’s poorly controlled. If your body lacks enough insulin, ketones build up in your body and acidify your blood. Acidosis occurs when your kidneys and lungs can’t keep your body’s pH in balance. Many of the body’s processes produce acid. For instance, your lungs and kidneys can usually compensate for slight pH imbalances, but problems with these organs can lead to excess acid in your body. If unchecked, metabolic acidosis leads to acidemia, i.e., blood pH is low (less than 7.35) due to increased production of hydrogen ions by the body or the inability of the body to form bicarbonate (HCO3−) in the kidney. Its causes are diverse, and its consequences can be serious, including coma and death. INTRODUCTION AND DEFINITION. Lactate levels greater than 2 meq/L represent hyperlactatemia, whereas lactic acidosis is generally defined as a serum lactate concentration above 4 meq/L. Lactic acidosis is the most common cause of metabolic acidosis in hospitalized patients. Although the acidosis is usually associated with an elevated anion gap, increased lactate levels can also be observed with a normal anion gap (most often if hypoalbuminemia is not identified and used to correct the anion gap). As fat is broken down, acids called ketones build up in the blood and urine. In high levels, ketones are poisonous. This condition is known as ketoacidosis. DKA is sometimes the first sign of type 1 diabetes in people who have not yet been diagnosed. It can also occur in someone who has already been diagnosed with type 1 diabetes. Acidosis refers to an excess of acid in the blood that causes the pH to fall below 7.35, and alkalosis refers to an excess of base in the blood that causes the pH to rise above 7.45. Many conditions and diseases can interfere with pH control in the body and cause a person's blood pH to fall outside of healthy limits. If the pH is low (under 7.35) and the bicarbonate levels are decreased (<24 mmol/l), metabolic acidemia is present, and metabolic acidosis is presumed. Due to respiratory compensation (hyperventilation), carbon dioxide is decreased and conversely oxygen is increased. What are acidosis and alkalosis? Acidosis and alkalosis describe the abnormal conditions that result from an imbalance in the pH of the blood caused by an excess of acid or alkali (base). This imbalance is typically caused by some underlying condition or disease. Diabetic ketoacidosis (DKA) is a life-threatening problem that affects people with diabetes. It occurs when the body cannot use sugar (glucose) as a fuel source because there is no insulin or not enough insulin. Fat is used for fuel instead.
It refers to an excess of acid in the blood that causes the pH to fall below 7.35, and an excess of base in the blood that causes the pH to rise above 7.45.
