Type 2 Diabetes Mellitus with Ketosis
What is Type 2 Diabetes Mellitus with Ketosis?
Type 2 diabetes mellitus with ketosis is a serious complication where your body starts breaking down fat for energy instead of using glucose. This happens when insulin levels drop too low or your body cannot use insulin properly. When fat breaks down, it creates acidic compounds called ketones that build up in your blood and appear in your urine.
While ketosis is more common in Type 1 diabetes, people with Type 2 can develop it too. This usually happens during severe illness, infection, major surgery, or extreme stress. Certain diabetes medications called SGLT2 inhibitors can also trigger a form called euglycemic diabetic ketoacidosis, where blood sugar may appear normal but ketones are dangerously high.
This condition requires immediate attention because high ketone levels can make your blood too acidic. Left untreated, it can lead to diabetic ketoacidosis, a medical emergency. Early detection through testing helps prevent serious complications and guides treatment decisions.
Symptoms
- Excessive thirst and dry mouth
- Frequent urination, sometimes with fruity-smelling urine
- Extreme fatigue and weakness
- Nausea, vomiting, or stomach pain
- Shortness of breath or rapid breathing
- Confusion or difficulty concentrating
- Fruity-smelling breath
- Flushed, dry skin
- Rapid heart rate
Some people may not recognize these symptoms right away, especially if they develop gradually. Others may feel fine initially but quickly worsen during an illness or stressful event.

Causes and risk factors
Type 2 diabetes with ketosis develops when your body cannot produce enough insulin or use it effectively during times of high metabolic stress. Common triggers include severe infections like pneumonia or urinary tract infections, heart attacks, strokes, pancreatitis, or major surgery. Missing insulin doses or not taking diabetes medications as prescribed can also lead to ketosis. Dehydration makes the problem worse by concentrating ketones in your blood.
Certain medications increase your risk, particularly SGLT2 inhibitors used to treat diabetes and heart failure. Other risk factors include poorly controlled blood sugar over time, alcohol use, pregnancy, and extreme low-carbohydrate diets. People who have had ketosis before are more likely to experience it again, especially during illness or injury.
How it's diagnosed
Doctors diagnose this condition by measuring ketone levels in your urine or blood. A urine ketone test is a simple, quick way to check if your body is producing excess ketones. Blood tests measure glucose levels, electrolytes, kidney function, and blood acidity to assess the severity of ketosis. Your doctor may also order tests to identify what triggered the ketosis, such as infection markers or cardiac enzymes.
Rite Aid offers testing that includes urine ketones to help detect this condition early. Testing through our Quest Diagnostics network gives you access to over 2,000 locations nationwide. Regular monitoring is important if you have Type 2 diabetes, especially when you feel unwell or experience unusual symptoms.
Treatment options
- Intravenous fluids to rehydrate and dilute ketones in your blood
- Insulin therapy to help your cells use glucose and stop breaking down fat
- Electrolyte replacement, especially potassium, to maintain heart and muscle function
- Treatment of underlying triggers like infections with antibiotics
- Adjusting or temporarily stopping SGLT2 inhibitors if they contributed to ketosis
- Eating small, frequent meals with balanced carbohydrates once you can tolerate food
- Staying well-hydrated with water and sugar-free drinks
- Monitoring blood sugar and ketone levels closely during recovery
- Working with your healthcare team to prevent future episodes

Frequently asked questions
Ketosis means your body is producing ketones, which may be mild or moderate. Diabetic ketoacidosis is a severe, life-threatening condition where very high ketone levels make your blood dangerously acidic. Ketosis can progress to ketoacidosis if left untreated, so early detection and treatment are critical.
Yes, though it is less common than in Type 1 diabetes. People with Type 2 can develop ketosis during severe illness, major stress, or when taking certain medications like SGLT2 inhibitors. In these situations, insulin levels drop low enough that your body starts burning fat and producing ketones.
You can use urine ketone test strips available at pharmacies without a prescription. Dip the strip in your urine sample and compare the color to the chart on the bottle. Test whenever you feel sick, your blood sugar is above 240, or you have symptoms like nausea or fruity breath.
Seek emergency care if you have moderate or high ketone levels, cannot keep down fluids, have severe stomach pain, or feel confused. Also go if your blood sugar stays above 300 despite treatment, you have trouble breathing, or your symptoms are getting worse quickly.
SGLT2 inhibitors are generally safe and effective for many people with Type 2 diabetes. However, they can increase ketosis risk, especially during illness or low-carb diets. Your doctor will help you understand the benefits and risks, and you may need to stop them temporarily when sick.
Take your diabetes medications as prescribed and monitor your blood sugar regularly. Stay well-hydrated, especially during illness or hot weather. Check for ketones when you are sick or your blood sugar is high, and contact your doctor early if ketones are present.
Fruity or sweet-smelling breath is a sign that your body is producing high levels of ketones. The specific ketone called acetone gets released through your lungs, creating this distinctive odor. This symptom means you need medical attention soon to prevent worsening ketosis.
Yes, this is called euglycemic diabetic ketoacidosis and can occur with SGLT2 inhibitors. Your blood sugar may be below 200 or even normal, but ketone levels are dangerously high. This is why testing ketones is important, not just blood sugar, especially if you take these medications.
With proper treatment, mild to moderate ketosis usually improves within 12 to 24 hours. Severe cases requiring hospitalization may take several days for ketone levels to normalize. Full recovery depends on treating the underlying cause and preventing dehydration.
Not necessarily, but illness increases your risk if you have Type 2 diabetes. Following your sick day plan, staying hydrated, checking ketones early, and contacting your doctor promptly can help prevent ketosis from developing. Many people manage illnesses without ever producing significant ketones.
