High ketone bodies in urine?
Hello Dr.
Hsiao, I recently had two urine ketone tests in April and mid-July, both showing positive results.
I also regularly monitor my blood glucose and hemoglobin A1c levels, which are normal.
Previously, I underwent an ERCP due to bile duct stones, which resulted in pancreatitis and caused my liver enzymes to rise to 500.
However, my liver enzymes are currently stable.
Do I need to undergo any further related tests? Thank you.

Dr. Xiao Yongxun reply Internal Medicine
Dear Miss Lin: The increase of ketones in the urine, unless caused by high blood sugar leading to diabetic ketoacidosis, is generally due to prolonged fasting or starvation, which triggers the breakdown of fats and results in an increase of ketones in the blood and urine.
Of course, there are other possibilities, but they are rare.
Therefore, monitoring is sufficient.
It is advisable to discuss this thoroughly with your attending physician, as I am not aware of what immediate tests may be necessary.

More Info
High levels of ketones in urine can be indicative of several underlying conditions, and your situation warrants a careful evaluation. Ketones are produced when the body breaks down fat for energy instead of carbohydrates, which can occur in various scenarios such as fasting, uncontrolled diabetes, or certain metabolic disorders. Given your history of pancreatitis and elevated liver enzymes, it is crucial to understand the context of your ketone levels.
Since you mentioned that both your blood sugar and glycated hemoglobin (HbA1c) levels are normal, this suggests that diabetes is less likely to be the cause of your elevated ketones. However, it is essential to consider other factors that may contribute to this condition. For instance, if you have been fasting or on a low-carbohydrate diet, this could explain the presence of ketones in your urine. Additionally, dehydration can concentrate urine and lead to higher ketone readings.
Given your history of pancreatitis, it is also important to rule out any potential complications related to your pancreas. Pancreatitis can affect the body's ability to metabolize fats and carbohydrates, which may lead to abnormal ketone levels. Therefore, further testing may be warranted to assess pancreatic function, including:
1. Amylase and Lipase Levels: These enzymes can help determine if there is ongoing pancreatic inflammation or dysfunction.
2. Comprehensive Metabolic Panel (CMP): This test can provide information about your liver and kidney function, as well as electrolyte balance, which is crucial in understanding your overall metabolic state.
3. Urine Analysis: A more detailed urine analysis may help identify other abnormalities, such as the presence of glucose, which could indicate a different underlying issue.
4. Endocrine Evaluation: If there are concerns about metabolic disorders, tests for hormones such as insulin and glucagon may be beneficial.
In addition to these tests, it is essential to monitor your symptoms closely. If you experience any signs of dehydration, such as increased thirst, dry mouth, or decreased urine output, it is crucial to address these issues promptly. Staying well-hydrated can help dilute the urine and potentially lower ketone levels.
Lastly, it is advisable to consult with your healthcare provider about your concerns. They can provide personalized recommendations based on your medical history and current health status. If necessary, they may refer you to a specialist, such as an endocrinologist or a gastroenterologist, for further evaluation.
In summary, while high ketones in urine can be concerning, your normal blood sugar levels and stable liver function are reassuring. However, given your history of pancreatitis, further testing may be warranted to ensure that there are no underlying issues affecting your metabolic health. Always keep an open line of communication with your healthcare provider to address any concerns and to ensure appropriate follow-up care.
