At hour 4, the patient developed circulatory shock which required vasopressor support and respiratory assistance. A plasma glucose level of mg dl-1 was not achieved until the total dosage of insulin amounted to 91, units at hour Insulin resistance was not observed from that point on.

The patient had neither insulin antibodies nor anti-insulin receptor antibodies in serologic testing. The insulin binding characteristics of the patient's erythrocytes were similar to those from healthy controls both with and without experimental acidosis and with a high level of beta-hydroxybutyrate.

Among multiple potential factors, the severe shock associated with DKA has been considered as a primary cause of the transient severe insulin resistance in this case. Abstract Transient extreme insulin resistance was encountered during an episode of diabetic ketoacidosis DKA in an insulin-treated diabetic patient.

Diabetes is a condition characterised by high blood glucose sugar levels. Diabetic ketoacidosis typically occurs in people with type 1 diabetes, which was previously known as juvenile diabetes or insulin dependent diabetes mellitus IDDM , though it can occasionally occur in type 2 diabetes.

This type of coma is triggered by the build-up of chemicals called ketones. Ketones are strongly acidic and cause the blood to become too acidic.

When there is not enough insulin circulating, the body cannot use glucose for energy. Instead, fat is broken down and then converted to ketones in the liver. The ketones can build up excessively when insulin levels remain too low.

Common causes of ketoacidosis include a missed dose of insulin or an acute infection in a person with type 1 diabetes. Ketoacidosis may be the first sign that a person has developed type 1 diabetes. In order to pick up the earliest signs of ketoacidosis, people with type 1 diabetes whose blood glucose levels are particularly high require more frequent monitoring of blood glucose.

Checking of ketone levels is also recommended. If available, blood ketone testing is preferred. If blood ketone testing is not available, urine testing may be used. A diabetic hyperosmolar coma is caused by severe dehydration and very high blood glucose levels hyperglycaemia.

Those at most risk of this type of coma are people with type 2 diabetes, who have an infection or acute illness and have reduced their intake of fluids. The kidneys respond to high levels of blood glucose by doing their best to remove it, along with a great deal of water.

They will become dehydrated and urgently need intravenous fluids. Without this kind of treatment, they may lapse into hyperosmolar coma. Hyperosmolar coma develops slowly over several days or weeks, so if the high blood glucose levels or dehydration are detected and treated early, coma can be prevented.

Hypoglycaemia , or low blood glucose levels below 3. If the blood glucose falls to very low levels, the person may become unconscious hypoglycaemic coma and seizures may occur. First aid for someone who has lapsed into a diabetic coma includes:.

A coma is a medical emergency. The cause of a diabetic coma is diagnosed using a number of tests including:. This page has been produced in consultation with and approved by:.

Blood sugar that's either too high or too low for too long may cause the following serious health problems, all of which can lead to a diabetic coma.

Diabetic ketoacidosis. If your muscle cells become starved for energy, your body may start breaking down fat for energy. This process forms toxic acids known as ketones. If you have ketones measured in blood or urine and high blood sugar, the condition is called diabetic ketoacidosis.

If it's not treated, it can lead to a diabetic coma. Diabetic ketoacidosis is most common in people who have type 1 diabetes. But it can also occur in people who have type 2 diabetes or gestational diabetes.

Diabetic hyperosmolar syndrome. When blood sugar is very high, the extra sugar passes from the blood into the urine. That triggers a process that draws a large amount of fluid from the body.

If it isn't treated, this can lead to life-threatening dehydration and a diabetic coma. Anyone who has diabetes is at risk of a diabetic coma, but the following factors can increase the risk:. Good day-to-day control of your diabetes can help you prevent a diabetic coma. Keep these tips in mind:.

Consider a continuous glucose monitor, especially if you have trouble maintaining stable blood sugar levels or you don't feel symptoms of low blood sugar hypoglycemia unawareness. Continuous glucose monitors are devices that use a small sensor inserted underneath the skin to track trends in blood sugar levels and send the information to a wireless device, such as a smart phone.

These monitors can alert you when your blood sugar is dangerously low or if it is dropping too fast. But you still need to test your blood sugar levels using a blood glucose meter even if you're using one of these monitors.

Continuous glucose monitors are more expensive than other glucose monitoring methods, but they may help you control your glucose better.

A continuous glucose monitor, on the left, is a device that measures blood sugar every few minutes using a sensor inserted under the skin. An insulin pump, attached to the pocket, is a device that's worn outside of the body with a tube that connects the reservoir of insulin to a catheter inserted under the skin of the abdomen.

Insulin pumps are programmed to deliver specific amounts of insulin continuously and with food. On this page. When to see a doctor. Risk factors. A Book: Guide to the Comatose Patient.

Anyone who has diabetes is at risk of a diabetic coma, but the following factors can increase the risk: Insulin delivery problems. If you're using an insulin pump, you have to check your blood sugar frequently.

Insulin delivery can stop if the pump fails or if the tubing catheter becomes twisted or falls out of place. A lack of insulin can lead to diabetic ketoacidosis. An illness, trauma or surgery.

When you're sick or injured, blood sugar levels can change, sometimes significantly, increasing your risk of diabetic ketoacidosis and diabetic hyperosmolar syndrome. Poorly managed diabetes. If you don't monitor your blood sugar properly or take your medications as directed by your health care provider, you have a higher risk of developing long-term health problems and a higher risk of diabetic coma.

Deliberately skipping meals or insulin. Sometimes, people with diabetes who also have an eating disorder choose not to use their insulin as they should, in the hope of losing weight. This is a dangerous, life-threatening thing to do, and it raises the risk of a diabetic coma.

Drinking alcohol. Alcohol can have unpredictable effects on your blood sugar. Alcohol's effects may make it harder for you to know when you're having low blood sugar symptoms.

This can increase your risk of a diabetic coma caused by hypoglycemia. Illegal drug use. Illegal drugs, such as cocaine, can increase your risk of severe high blood sugar and conditions linked to diabetic coma.

There are three main causes of diabetic coma. Two causes are most often associated with type 1 diabetes, and one is most often associated with type 2 diabetes. According to the American Diabetes Association , a person with type 1 diabetes will experience symptoms of hypoglycemia twice a week on average.

People with type 2 diabetes who use insulin are less likely to experience hypoglycemia, but it can still happen. Hypoglycemia usually only occurs in people who are receiving treatment with insulin, but it can occur with oral medications that increase insulin levels in the body.

Eating or drinking a source of glucose will bring blood glucose levels back into the healthy range, and the person will feel better almost immediately. If the person does not notice or act on the symptoms and the glucose levels continue to decrease, they will become unconscious.

Diabetic ketoacidosis is a serious complication of type 1 diabetes that arises when levels of ketones in the blood become too high and the acid level of the blood increases. It can also result in a diabetic coma.

The levels of ketones in the blood can become too high if an individual uses fat rather than sugar as an energy source.

This occurs in people with type 1 diabetes for various reasons, including not receiving enough insulin or illness. People with diabetic ketoacidosis will also have high glucose levels in their blood since the sugar cannot go from the blood and into the cells.

The body tries to reduce the high glucose levels by allowing glucose to leave the body in the urine. However, this also causes the body to lose more water. A person with diabetic ketoacidosis will :.
