HHS happens when your blood glucose (sugar) levels are too high for a long period, leading to severe dehydration and confusion. Blood sugar levels are usually over 600 milligrams per deciliter (mg/dL). If you don't get treatment for HHS in time, it can lead to a coma.

What is the lowest your blood sugar can go before you go into a coma?

Coma can occur at glucose levels in the range of 2.3–2.7 mmol/l (41–49 mg/dl) (9) as well as at lower glucose levels. All of these responses are typically corrected after the plasma glucose concentration is raised.

How long does it take for a diabetic to go into a 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.

What is the danger zone for blood sugar?

Blood sugar readings between 180 mg/dL and 250 mg/dL are considered high blood glucose or hyperglycemia. A reading of 250 mg/dL or higher is dangerous. This severe high blood sugar requires emergency medical treatment. Two or more readings of 300 mg/dL or higher in sequence are very dangerous.

What is stroke level for sugar?

A fasting blood glucose (sugar) level of 126 milligrams per deciliter (mg/dL) or higher is dangerous. People with diabetes are twice as likely to have a stroke as people who do not.

Causes of Diabetic Coma

What is an alarming blood sugar level?

In general, a blood sugar reading of more than 180 mg/dL or any reading above your target range is too high. A blood sugar reading of 300 mg/dL or more can be dangerous. If you have 2 readings in a row of 300 or more, call your doctor. What causes high blood sugar?

What happens right before a diabetic coma?

Severe symptoms of DKA that could happen before a diabetes-related coma include: Nausea and vomiting. Abdominal pain. Rapid, deep breathing at a consistent pace (Kussmaul breathing).

What is the highest blood sugar level that is safe?

A fasting blood sugar level less than 100 mg/dL (5.6 mmol/L) is normal. A fasting blood sugar level from 100 to 125 mg/dL (5.6 to 6.9 mmol/L) is considered prediabetes. If it's 126 mg/dL (7 mmol/L) or higher on two separate tests, you have diabetes.

What is a dangerously high blood sugar level?

But generally, for people with diabetes, a level of 180 milligrams per deciliter (mg/dL) within 2 hours of eating is considered too high. That's called hyperglycemia. The higher it goes, the more dangerous it becomes. For most people, blood sugar below 70 mg/dL is considered too low and is called hypoglycemia.

What is a high blood sugar level for a diabetic coma?

If your blood sugar level goes above 600 milligrams per deciliter (mg/dL), or 33.3 millimoles per liter (mmol/L), the condition is called diabetic hyperosmolar syndrome. When blood sugar is very high, the extra sugar passes from the blood into the urine.

What is a lethal high blood sugar level?

diabetic hyperosmolar hyperglycemic syndrome (HHS). With HHS, blood sugars can be very high, reaching 600 mg/dl or higher. Left untreated, HHS can cause a coma or death.

What is the emergency blood sugar level?

A high blood sugar level of more than 240 with or without symptoms requires calling the doctor immediately. Healthcare providers will administer ER treatment to reduce the level and symptoms. After leaving the ER, follow the doctor's instructions to avoid another incident of DKA.

What is a fatally low blood sugar level?

If hypoglycemia becomes severe, you may not be able to safely swallow food or drink. By this point, your blood glucose level is less than 54 mg/dL—often below 40 mg/dL. You may feel very confused, pass out, or have a seizure. Without prompt treatment, severe hypoglycemia may lead to a coma or even death.

At what blood sugar level do you lose consciousness?

Severe low blood sugar is below 54 mg/dL. Blood sugar this low may make you faint (pass out). Often, you'll need someone to help you treat severe low blood sugar. People with diabetes can have low blood sugar as often as once or twice a week.

What are three signs of a diabetic emergency?

Signs and symptoms of a diabetic emergency

Someone who is hypoglycaemic (having a low blood sugar diabetic emergency) may have clammy skin, be sweating, feel drowsy and confused or feel faint and be unresponsive.

What is a worrisome blood sugar level?

According to the University of Michigan, blood sugar levels of 300 mg/dL or more are considered dangerous. Therefore, you should see your doctor if you have two consecutive blood sugar results of 300 or more.

What drink lowers blood sugar?

Drinking water is an excellent way to stay hydrated without consuming sugar. Green tea, cow's milk, and fermented milk (kefir) could also help you manage your blood sugar responses. Coffee also contains compounds that may help regulate blood sugar, but confirming this requires more research.

At what blood sugar do you go into a coma?

If an individual's sugar level in the blood and the brain drops to below 3.5 mmol/l, they are at risk of losing consciousness and falling into a diabetic coma.

How do I bring my blood sugar down immediately?

The fastest way to lower blood sugar is to take fast-acting insulin medication. Exercise can also help to bring down blood sugar levels quickly. Diet and lifestyle changes can help manage overall blood sugar levels, but for immediate action, prescription medication or medical assistance may be necessary.

Should I go to the hospital if my blood sugar is over 200?

Seek immediate help from your care provider or call 911 if:

You have ongoing diarrhea or vomiting, and you can't keep any food or fluids down. Your blood glucose levels stay above 240 milligrams per deciliter (mg/dL) (13.3 millimoles per liter (mmol/L)) and you have symptoms of ketones in your urine.

What is a critical blood sugar level?

The organization's laboratory critical value policy at the time of the event defined a critical blood glucose value as < 40 mg/dL. However, the American Diabetes Association (ADA) standards of medical care in diabetes for critical blood glucose values were updated to < 54 mg/dL in 2017.

Can drinking water lower blood sugar?

Drinking water won't lower your blood sugar levels, but staying hydrated can help you manage them if you have diabetes. Regularly drinking enough water is healthy, and research has linked it to a reduced risk of high blood sugar and diabetes.

What is a bad blood sugar level for a diabetic?

If someone has readings over 7.8 mmol/l (140 mg/dl), they are considered to have high blood sugar (hyperglycemia). Left untreated, type 1 diabetes can lead to blood sugar levels of over 27.8 mmol/l (500 mg/dl). Such high levels tend to be uncommon in type 2 diabetes.
