Ketoacidosis: A Diabetes Complication

Ketoacidosis can affect both type 1 diabetes and type 2 diabetes patients. It's a possible short-term complication of diabetes, one caused by hyperglycemia—and one that can be avoided. Diabetic ketoacidosis (DKA) and hyperosmolar hyperglycemic state (HHS) are two of the most serious complications of diabetes. These hyperglycemic emergencies continue to be important causes of mortality among persons with diabetes in spite of all of the advances in understanding diabetes. The annual incidence rate of DKA estimated from population-based studies ranges from 4.8 to 8 episodes per 1,000 patients with diabetes. Unfortunately, in the US, incidents of hospitalization due to DKA have increased. Currently, 4% to 9% of all hospital discharge summaries among patients with diabetes include DKA. The incidence of HHS is more difficult to determine because of lack of population studies but it is still high at around 15%. The prognosis of both conditions is substantially worsened at the extremes of age, and in the presence of coma and hypertension. Why and How Does Ketoacidosis Occur? The pathogenesis of DKA is more understood than HHS but both relate to the basic underlying reduction in the net e Continue reading >>

    The human body is in a constant process of maintaining equilibrium. The byproducts of burning fat for energy (ketones) are deposited in the blood for excretion. As the ketones build up in your system, the pH of your blood drops and you become acidotic. As stated above, your body is trying to maintain equilibrium, so it will do certain things to eliminate as much acid from your system as possible, as quickly as possible. One way is to vomit, which dumps huge amounts of H+ instantly. Other reactions are increased respirations to eliminate CO2, as well as dumping the ketones and H+ out through your urine.
    As a side note, the dumping of H+ through urine causes the retention of potassium and you become hyperkalemic (aka "too-much-potassium-emia"). This inhibits myocardial function and can put you into cardiac arrest. This is why extreme no-carb diets are a very bad thing!
    Hope that helps!
