Alcoholic Ketoacidosis: Etiologies, Evaluation, and Management

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.

Early symptoms are related to hyperglycemia and include polydipsia… Read more , which may be recognized by elevated levels of glycosylated hemoglobin (HbA1C). 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. Patients who appear significantly ill and those with positive ketones should have arterial blood gas and serum lactate measurements.

Alcoholic ketoacidosis: clinical and laboratory presentation, pathophysiology and treatment

In addition to this, the increased NADH further suppresses gluconeogenesis and reduces free glucose, perpetuating ketogenesis.[6] After abrupt withdrawal, rising catecholamine levels as a bodily response cause lipolysis and ketosis. The high ratio of NADH to NAD+ also favors the reduction of acetoacetate to beta-hydroxybutyrate. The underlying pathophysiology is related to poor glycogen stores and elevated nicotinamide adenine dinucleotide and hydrogen. This results in metabolic acidosis with elevated beta-hydroxybutyrate levels. Patients with AKA most commonly present with a history of alcohol use (acute or chronic), poor oral intake, gastrointestinal symptoms, and ketoacidosis on laboratory assessment. Patients are generally dehydrated, and serum glucose can be low, normal, or mildly elevated.

HHS and DKA have similar symptoms, including feeling very thirsty, having to pee more than usual, dry mouth, and feeling confused or less alert, weak, or nauseous. Diabetic ketoacidosis is treated with fluids, electrolytes — such as sodium, potassium and chloride — and insulin. Perhaps surprisingly, the most common complications of diabetic ketoacidosis are related to this lifesaving treatment. Without enough insulin, the body can’t use sugar to make the energy it needs. This causes the release of hormones that break down fat for the body to use as fuel. Ketones build up in the blood and eventually spill over into the urine.

What to Do if You Have Fruity Breath

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. 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.

  • For men, heavy drinking is typically defined as consuming 15 drinks or more per week.
  • The clinical and biochemical features of AKA are summarised in boxes 1 and 2.
  • The dextrose will also increase glycogen stores and diminish counterregulatory hormone levels.

If your urine doesn’t have the characteristic keto urine smell, and your breath doesn’t also smell, you may want to consider other reasons for your odoriferous pee. Even in the absence of ketones, being dehydrated can lead to smelly urine, so be sure to drink up. Certain foods and beverages can make urine smell more pungent, including asparagus, coffee and tea. Vitamins and medications can also lead to a more distinct urine smell. The odor is often described as “fruity,” but not in a good way. Although not as common, your sweat and urine may have a similar odor.

Alcoholic ketoacidosis: a cause of sudden death of chronic alcoholics

This facilitates a natural metabolic process called ketosis, in which the body breaks down fatty acids to produce substances called ketones, which can be used for energy. Diabetic ketoacidosis usually happens because your body doesn’t have enough insulin. Your cells can’t use the sugar in your blood for energy, so they use fat for fuel instead. If the process goes on for a while, they could build up in your blood.

  • Emergency clinician knowledge of the evaluation and management of AKA is essential in caring for these patients.
  • Under normal conditions, cells rely on free blood glucose as the primary energy source, which is regulated with insulin, glucagon, and somatostatin.
  • All remaining papers were retrieved and the reference lists hand searched for any additional information sources.

Alcoholic ketoacidosis is a recognised acute complication in alcohol dependent patients. Given the frequency with which the condition is seen in other countries, the possibility exists that many cases may be unrecognised and misdiagnosed in UK EDs. AKA should be included in the differential diagnosis of alcohol dependent patients presenting with acute illness. Management is based around exclusion of serious pathology and specific treatment for AKA where it is present. A possible link between AKA and sudden death in chronic alcoholism has been proposed but remains unconfirmed.

One complication of alcoholic ketoacidosis is alcohol withdrawal. Your doctor and other medical professionals will watch you for symptoms of withdrawal. Your doctor will figure out if you have DKA by doing a physical exam and asking you about your symptoms, alcoholic ketoacidosis smell experiences, and medical history. They’ll check your blood sugar, ketones in your pee and/or blood, and your blood pH and bicarbonate levels. The liver’s inability to synthesize and release glucose can also lead to dangerously high levels of lactate.

  • Group meetings provide support for people trying to quit drinking.
  • Alcohol produces structural changes in human liver mitochondria within days.
  • According to an article published in October 2015 in the Journal of Medical Case Reports, non-diabetic ketoacidosis occurs very rarely, and is usually due to starvation or alcoholism.
  • Failure to make the diagnosis can result in severe metabolic abnormalities, acidosis, and shock.
  • You may get vitamin supplements to treat malnutrition caused by excessive alcohol use.
