Healthcare professionals diagnose AKA through a combination of clinical evaluation and specific laboratory tests. Typically, an alcohol binge leads to vomiting and the cessation of alcohol or food intake for ≥ 24 hours. During this period of starvation, vomiting continues and abdominal pain develops, leading the patient to seek medical attention. Alcoholic ketoacidosis is a condition that can happen when you’ve had a lot of alcohol and haven’t had much to eat or have been vomiting.

Bedside testing reveals a low or absent breath alcohol, normal blood sugar, metabolic acidosis, and the presence of urinary ketones, although these may sometimes be low or absent. An altered level of consciousness should prompt consideration of alternative diagnoses such as hypoglycaemia, seizures, sepsis, thiamine deficiency, or head injury. Arterial blood gas and biochemistry studies reveal a raised anion gap metabolic acidosis without evidence of lactic or diabetic ketoacidosis. Patients improved rapidly (within 12 hours) with intravenous glucose and large amounts of intravenous saline, usually without insulin (although small amounts of bicarbonate were sometimes used). The patient should have blood glucose checked on the initial presentation.
Treatment of Alcoholic Ketoacidosis
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 general, the prognosis for a patient presenting with AKA is good as long as the condition is identified and treated early. The major cause of morbidity and mortality in patients diagnosed with AKA is under-recognition of concomitant diseases (that may have precipitated the AKA, to begin with). These include acute pancreatitis, gastrointestinal bleeding, and alcohol withdrawal. Mortality specifically due to AKA has been linked to the severity of serum beta-hydroxybutyric acid in some studies. It should be used as an indicator of the severity of the disease.13 Identifying these high-risk patients can help set the intensity of monitoring required for the patient to ensure optimal patient outcomes are achieved.
Complications
- Carnitine acyltransferase (CAT) transports free fatty acids into the mitochondria and therefore regulates their entry into the oxidative pathway.
- In patients suspected of having alcoholic ketoacidosis, serum electrolytes (including magnesium), blood urea nitrogen (BUN) and creatinine, glucose, ketones, amylase, lipase, and plasma osmolality should be measured.
- Joining a local chapter of Alcoholics Anonymous may provide you with the support you need to cope.
- Diabetic ketoacidosis is treated with fluids, electrolytes — such as sodium, potassium and chloride — and insulin.
- When your liver uses up its stored glucose and you aren’t eating anything to provide more, your blood sugar levels will drop.
When this happens, it can cause ketones, which are acids, to build up in your blood. If not treated quickly, alcoholic ketoacidosis may be life-threatening. The clinical and biochemical features of AKA are summarised in boxes 1 and 2.
- Additionally, it has been found that episodes of AKA are often triggered by a lack of oral nutrition over a period ranging from one to three days, particularly in individuals with a history of alcohol use disorder (AUD).
- Both steps require the reduction of nicotinamide adenine dinucleotide (NAD+) to reduced nicotinamide adenine dinucleotide (NADH).
- This condition is characterized by the presence of high levels of ketones in the blood, which are acidic by-products of fat metabolism.
- If you feel ill or stressed or you’ve had a recent illness or injury, check your blood sugar level often.
- Your doctor and other medical professionals will watch you for symptoms of withdrawal.
Ethanol metabolism
Fat cells begin breaking down, producing compounds called ketones. Ketones provide some energy to cells but also make the blood too acidic (ketoacidosis). This ketoacidosis is similar to the ketoacidosis that occurs in diabetes except that, unlike in diabetic ketoacidosis, blood glucose levels are low. Examination should reveal a clear level of consciousness, generalised abdominal tenderness (without peritoneal signs), and tachypnoea. There may be concomitant features of dehydration or early acute alcohol withdrawal.
Possible complications of the treatments
- In 1940, Dillon et al1 described a series of nine patients who had episodes of severe ketoacidosis in the absence of diabetes mellitus, all of whom had evidence of prolonged excessive alcohol consumption.
- If history does not rule out toxic alcohol ingestion as a cause of the elevated anion gap, serum methanol and ethylene glycol levels should be measured.
- If your blood glucose level is elevated, your doctor may also perform a hemoglobin A1C (HgA1C) test.
Although well described in international emergency medicine literature, UK emergency physicians rarely make the diagnosis of AKA. There is increasing evidence that rather than being benign and self limiting, AKA may be a significant cause of mortality in patients with alcohol dependence. This literature review discusses the history, characterisation, pathophysiology, diagnosis, and management of AKA. Treatment for Alcoholic Ketoacidosis (AKA) primarily focuses on correcting the dehydration, electrolyte imbalances, and acidosis that characterize this condition. Without enough insulin, the body can’t use sugar to make the energy it needs.
- Generally, the physical findings relate to volume depletion and chronic alcohol abuse.
- Alcoholic ketoacidosis can develop when you drink excessive amounts of alcohol for a long period of time.
- Toxic metabolites of both substances result in severe metabolic acidosis with wide anion gap and wide osmolal gap.18 Neither, however, causes ketosis.
- Examination should reveal a clear level of consciousness, generalised abdominal tenderness (without peritoneal signs), and tachypnoea.
- Moreover, volume depletion increases the concentration of counter-regulatory hormones, further stimulating lipolysis and ketogenesis.
Symptoms of Alcoholic Ketoacidosis
They provide some energy to your cells, but too much may cause your blood to become too acidic. People who drink large quantities of alcohol may not eat regularly. Not eating enough or vomiting can lead to periods of starvation. Alcoholic ketoacidosis can develop when you drink excessive amounts of alcohol for a long period of time. Excessive alcohol consumption often causes malnourishment (not enough nutrients for the body to function well).
Management and alcoholic ketoacidosis smell prevention of Alcoholic Ketoacidosis (AKA) strongly rely on making significant lifestyle changes, particularly in relation to alcohol consumption and nutritional intake. Since AKA often develops in the context of heavy alcohol use combined with poor dietary habits, addressing these areas is crucial for both recovery and prevention of recurrence. Prolonged vomiting leads to dehydration, which decreases renal perfusion, thereby limiting urinary excretion of ketoacids.
