Furthermore, continued alcohol metabolism results in diminished gluconeogenesis. Both the depletion of glycogen and diminished gluconeogenesis lead to lower blood sugar levels. Because insulin restrains glucagon secretion, lower insulin secretion allows increased glucagon secretion, setting the stage for the development of ketoacidosis.
- Nausea, vomiting, and abdominal pain were by far the most commonly observed complaints.
- Alcoholic ketoacidosis (AKA) is a condition seen commonly in patients with alcohol use disorder or after a bout of heavy drinking.
- These include acute pancreatitis, gastrointestinal bleeding, and alcohol withdrawal.
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. When this happens, it can cause ketones, which are acids, alcoholic ketoacidosis smell to build up in your blood. If not treated quickly, alcoholic ketoacidosis may be life-threatening. Your doctor and other medical professionals will watch you for symptoms of withdrawal.
Emergent Treatment of Alcoholic Ketoacidosis
The combination of alcohol-induced hypoglycemia, hypoglycemic unawareness, and delayed recovery from hypoglycemia can lead to deleterious health consequences. For example, Arky and colleagues (1968) studied five diabetics who experienced severe hypoglycemia after ingesting alcohol. In all five patients, the alcohol-induced hypoglycemia induced neurological changes, such as incontinence, inability to follow simple commands, perseveration,4 disorientation, and impairment of recent memory. In three patients, those changes did not reverse, even after months or years. The two other patients died as a result of complications indirectly related to their hypoglycemia-induced neurological changes.
- The diabetic nurse should follow all outpatients to ensure medication compliance, followup with clinicians, and adopting a positive lifestyle.
- Management is based around exclusion of serious pathology and specific treatment for AKA where it is present.
- Alcohol metabolism in the liver, however, actually shuts down the process of gluconeogenesis and thus the second line of defense against hypoglycemia.
- Other electrolyte abnormalities concomitantly present with alcohol abuse and poor oral intake include hypomagnesemia and hypophosphatemia.
- Note information about the patient’s social situation and the presence of intoxicating agents besides alcohol.
- Further, vitamin K administration in our patient resulted in normalization of his INR.
Most importantly, insulin leads to the uptake of the sugar glucose into muscle and fat tissue and prevents glucose release from the liver, thereby lowering blood sugar levels (e.g., after a meal) (see figure). As a result of the immune system’s attack, the beta cells can no longer produce insulin. Consequently, the patient essentially experiences total insulin lack.
The liver normally re-incorporates free fatty acids into triglycerides, which are then packaged and secreted as part of a group of particles called very low-density lipoproteins (VLDL). In patients with ketoacidosis, however, the liver metabolizes the incoming free fatty acids in an additional, unusual way. Under the influence of excess glucagon, some of the free fatty acids are converted to ketone bodies and secreted into the blood, causing severe health consequences. 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. 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.
The acetic acid can be shunted towards ketogenesis in favorable insulin/glucagon concentrations, which is seen in hypoglycemia. In addition to this, the increased NADH further suppresses gluconeogenesis and reduces free glucose, perpetuating ketogenesis. 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. People who consume a lot of alcohol during one occasion often vomit repeatedly and stop eating. If the vomiting and starvation go on for a day or more, the liver’s normal stores of sugar (glucose) decrease.
Associated disease states
Accordingly, more studies are needed to determine whether the beneficial effects of daily moderate alcohol consumption outweigh the deleterious effects. Diabetics clearly should avoid heavy drinking (i.e., more than 10 to 12 drinks per day), because it can cause ketoacidosis and hypertriglyceridemia. Moreover, heavy drinking in a fasting state can cause hypoglycemia and ultimately increase diabetics’ risk of death from noncardiovascular causes. Diabetes and alcohol consumption are the two most common underlying causes of peripheral neuropathy. Among diabetics, the prevalence of neuropathy with obvious symptoms (i.e., symptomatic neuropathy) increases with increasing disease duration.
- In addition to isotonic fluid replacement, dextrose-containing intravenous fluids are needed.
- In most patients, the disease develops before age 40, primarily during childhood or adolescence.
- Hyperglycemia is the typical finding at presentation with DKA, but patients can present with a range of plasma glucose values.
- The resulting increase in the NADH/NAD+ ratio inhibits hepatic gluconeogenesis and elevates the ratio of hydroxybutyric acid to acetoacetic acid.
