The patient might be tachycardic, tachypneic, profoundly orthostatic, or frankly hypotensive as a result of dehydration from decreased oral intake, diaphoresis, and vomiting. Alcoholic ketoacidosis should be differentiated from other alcohol ingestions. Methanol and ethylene glycol ingestions do not produce ketosis, and acidosis tends to be severe. The presence of a large osmolal gap suggests acute isopropyl, ethanol, methanol, or ethylene glycol ingestion.
- You can prevent alcoholic ketoacidosis by limiting your alcohol intake.
- Profound dehydration can culminate in circulatory collapse and/or lactic acidosis.
- Flow cytometric enumeration with anti-D was also performed in one case.
- Alcoholic Ketoacidosis is a sample topic from the 5-Minute Emergency Consult.
- If your blood glucose level is elevated, your doctor may also perform a hemoglobin A1C test.
- It is essential to administer thiamine before any glucose administration to avoid Wernicke’s encephalopathy preci[itation.
alcoholic ketoacidosis is a serious condition that can result from heavy alcohol use over a long period. It occurs when there are high levels of ketones in the blood, which can lead to coma and even death. Ketone bodies are generated by the liver in the fasting state, under conditions of low glucose. Hepatocytes beta-oxidize long-chain fatty acids to generate acetyl-CoA, which is then converted to acetoacetic acid, beta-hydroxybutyric acid, and acetone, the three major ketones. In contrast to previously reported patients with “alcoholic ketoacidosis,” severe acidemia was uncommon in this series. Indeed, seven patients were alkalemic, because of coexisting respiratory or metabolic alkalosis.

Dehydration and volume constriction directly decrease the ability of the kidneys to excrete ketoacids. Profound dehydration can culminate in circulatory collapse and/or lactic acidosis. Prolonged vomiting leads to dehydration, which decreases renal perfusion, thereby limiting urinary excretion of ketoacids. Moreover, volume depletion increases the concentration of counter-regulatory hormones, further stimulating lipolysis and ketogenesis. Plasma glucose levels are usually low or normal, but mild hyperglycemia sometimes occurs.
- Patients develop acidosis, which causes an increase in respiratory rate and fluid loss.
- AKA is characterized by metabolic acidosis with an elevated anion gap, elevated serum ketone levels, and a normal or low glucose concentration.
- Hormone-sensitive lipase is normally inhibited by insulin, and, when insulin levels fall, lipolysis is up-regulated, causing release of free fatty acids from peripheral adipose tissue.
- In particular, cases of AKA can be misdiagnosed as diabetic ketoacidosis .
Alcoholic ketoacidosis is a clinical syndrome seen mostly in patients with chronic alcohol use disorder and frequently seen in patients who binge drink. Typical patients are usually chronic drinkers who are unable to tolerate oral nutrition for a 1 to 3 day period. Patients often have a recent bout of heavy drinking before the period of relative starvation, with persistent vomiting and abdominal pain contributing to their inability to tolerate PO intake. In general, the prognosis for a patient presenting with AKA is good as long as the condition is identified and treated early.

Ethanol metabolism results in NAD depletion manifesting as a higher ratio of the reduced form of nicotinamide adenine dinucleotide to NAD. When glycogen stores are depleted in a patient stressed by concurrent illness or volume depletion, insulin secretion is also suppressed. Under these same conditions, glucagon, catecholamine, and growth hormone secretion are all stimulated. This hormonal milieu inhibits aerobic metabolism in favor of anaerobic metabolism and stimulates lipolysis.
However, the long-term prognosis depends on the severity of the underlying alcohol abuse disorder. Increased availability of free fatty acids, which provide the major substrate for ketone body formation. In AKA, the increased ratio of NADH/NAD+ increases the proportion of beta hydroxybutyrate relative to acetoacetate. Patients develop acidosis, which causes an increase in respiratory rate and fluid loss. Alcoholic ketoacidosis most commonly happens in people who have alcohol use disorder and chronically drink a lot of alcohol. But it can happen after an episode of binge drinking in people who do not chronically abuse alcohol.

The lack of nutrients other than alcohol causes the formation of ketones and elevated gap ketoacidosis in the absence of diabetes. If you chronically abuse alcohol, you probably don’t get as much nutrition as your body needs. Going on a drinking binge when your body is in a malnourished state may cause abdominal pain, nausea, or vomiting. Infection or other illnesses such as pancreatitis can also trigger alcoholic ketoacidosis in people with alcohol use disorder. Due to vomiting, resulting in a relatively normal pH; the main clue is the elevated anion gap.
