If you are managing diabetes, the term “ketones” has likely surfaced in your conversations with healthcare providers. Often linked to diabetic ketoacidosis (DKA), a serious complication, understanding ketones is crucial for your health and well-being. But what exactly are ketones, and why are they considered dangerous?
It’s understandable to feel concerned, but being well-informed and prepared is your best approach to managing diabetes effectively. Let’s delve into the essentials of ketones, their risks, and how to manage them.
1) Decoding Ketones: What Are They?
In a healthy body, glucose, derived from the food we eat, serves as the primary energy source, facilitated by insulin. Insulin acts like a key, allowing glucose to enter cells and fuel our body’s functions. However, when there’s insufficient insulin, glucose can’t be effectively utilized for energy. In response, the body initiates a backup plan: it starts breaking down stored fat to generate energy. Ketones are the chemical byproducts of this fat-burning process.
This metabolic shift typically occurs in individuals with type 1 diabetes when insulin is lacking for extended periods. This can happen due to missed insulin doses, malfunctioning insulin pumps, or inadequate monitoring of blood sugar levels. Moreover, during periods of significant physical stress, such as serious illnesses in both type 1 and type 2 diabetes, the body’s insulin needs may increase. If insulin doses aren’t adjusted accordingly to cope with the stress of illness, ketone production can also be triggered.
While anyone with diabetes can develop ketones, it’s more frequently observed in individuals with type 1 diabetes due to their absolute dependence on insulin.
2) The Danger of Ketones: Why Are They Harmful?
Ketones disrupt the delicate chemical equilibrium of your blood. If ketone production continues unchecked, they accumulate to toxic levels, essentially poisoning the body. Our bodies are not designed to handle excessive amounts of ketones. To compensate, the kidneys attempt to expel them through urine. Despite this effort, if the underlying cause isn’t addressed, ketones will build up in the bloodstream.

The presence of ketones, especially in significant amounts, can be a critical warning sign, indicating the onset or imminent development of diabetic ketoacidosis (DKA). DKA is a life-threatening medical emergency that requires immediate attention.
3) When and How to Test for Ketones?
Regular ketone testing is a proactive step in managing your diabetes, particularly during specific situations. It’s generally recommended to check for ketones every four to six hours when certain conditions arise. Consult your healthcare provider to determine the most appropriate testing frequency and guidelines tailored to your diabetes management plan.
Situations that warrant ketone testing include:
- Elevated Blood Sugar Levels: When your blood sugar exceeds 300 mg/dL (or a level specified by your doctor).
- Gastrointestinal Distress: Experiencing nausea, vomiting, or unexplained abdominal pain.
- Illness: During periods of sickness, such as a cold or flu, as illness can increase the risk of ketone production.
- Persistent Fatigue: Feeling unusually tired or experiencing unexplained exhaustion.
- Dehydration Symptoms: Increased thirst and a persistently dry mouth.
- Flushed Skin: Noticeable redness of the skin.
- Respiratory Issues: Difficulty breathing or shortness of breath.
- Fruity Breath Odor: A distinctive “fruity” smell on your breath, which is a characteristic sign of ketones.
- Cognitive Changes: Feeling confused, disoriented, or experiencing a sense of mental “fog”.
Ketone testing is conveniently performed using urine ketone test strips, readily available at pharmacies. These kits are designed for quick and straightforward use. However, it’s crucial to meticulously follow the instructions provided with the test strips to ensure accurate results. Always keep test strips readily accessible and check their expiration date to guarantee their effectiveness.
Take the time to thoroughly understand the testing procedure in advance. If you’re unsure about any step, request a demonstration from your doctor, nurse, or pharmacist. Typically, the test involves dipping a test strip into a urine sample and waiting for a specified time for a color change to occur. You then compare the color of the strip to a color chart printed on the packaging to estimate the ketone concentration in your urine. Remember to meticulously record your test results, as this information will be valuable for your healthcare team.
4) Interpreting Results: When to Contact Your Doctor
Prompt communication with your healthcare provider is essential when your urine ketone test results indicate moderate or large amounts of ketones. These levels are a clear indication that your diabetes is not well-controlled or that you may be developing an illness-related complication. If you are unable to reach your diabetes care team immediately, seek urgent medical attention at the nearest emergency room or urgent care facility.
Share your recorded ketone test results and any related symptoms with your medical team. This data provides crucial insights to guide your treatment plan and necessary adjustments to your diabetes management strategy.
The detection of small or trace amounts of ketones in urine may signal the initial stages of ketone buildup. In such cases, it’s advisable to proactively increase your fluid intake, prioritizing water, to help flush out ketones. Take immediate steps to address and correct any elevated blood sugar levels. Re-test for ketones again within a few hours to monitor if the levels are increasing. If ketone levels persist or escalate, promptly contact your doctor for further guidance.
5) Exercise Considerations: When to Avoid Physical Activity
Exercise is generally beneficial for managing blood sugar levels. However, when ketones are present, especially in moderate or large amounts, and blood sugar is elevated, exercise becomes contraindicated. Never engage in physical activity under these circumstances. Exercising when ketones are present can paradoxically worsen the situation and potentially drive blood sugar levels even higher, exacerbating the risk of DKA.
Understanding ketones, recognizing the signs that warrant testing, and knowing how to respond to test results are vital components of diabetes self-management. By staying informed and proactive, you can effectively minimize the risks associated with ketones and maintain optimal health.
