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.
When to see a doctor. According to the University of Michigan, blood sugar levels of 300 mg/dL or more can be dangerous. They recommend calling a doctor if you have two readings in a row of 300 or more. Call your doctor if you're worried about any symptoms of high blood sugar.
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.
Low blood sugar is called hypoglycemia. A blood sugar level below 70 mg/dL (3.9 mmol/L) is low and can harm you. A blood sugar level below 54 mg/dL (3.0 mmol/L) is a cause for immediate action.
If your blood sugar levels are consistently high (usually above 20 mmol/L in adults and above 14 mmol/L in children), you may have moderate to severe symptoms of high blood sugar.
If your blood sugar level is 15 mmol/l or more, you should check your blood or urine for ketones. If ketones are present, it is likely that you do not have enough insulin in your body. This means you may need to increase your dose or give yourself an extra dose.
Hyperglycemia, the term for expressing high blood sugar, has been defined by the World Health Organisation as: Blood glucose levels greater than 7.0 mmol/L (126 mg/dl) when fasting. Blood glucose levels greater than 11.0 mmol/L (200 mg/dl) 2 hours after meals.
An ambulance will be needed if someone has either very high or very low blood sugar levels that presents an immediate danger and neither they nor anyone around is confidently able to treat them. Ketoacidosis and Hyperosmolar Hyperglycemic Nonketotic Syndrome are both life threatening conditions.
Take Insulin
The preferred—and quickest—method of treating hyperglycemia is to take rapid-acting insulin such as Humalog, Novolog, or Apidra. 5 If you have type 1 diabetes, you may be able to get a correction dose through your insulin pump, as well.
In general: Less than 140 mg/dL (7.8 mmol/L ) is normal. 140 to 199 mg/dL (7.8 to 11.0 mmol/L ) is consistent with prediabetes. 200 mg/dL (11.1 mmol/L ) or higher after two hours suggests diabetes.
Drinking water regularly may rehydrate the blood, lower blood sugar levels, and reduce diabetes risk ( 20 , 21 ). Keep in mind that water and other zero-calorie drinks are best. Avoid sugar-sweetened options, as these can raise blood glucose, drive weight gain, and increase diabetes risk ( 22 , 23 ).
Call 000 or emergency medical assistance if: You are sick and can't keep any food or fluids down. Your blood glucose levels are persistently above 15 mmol/L and you have ketones. Your health is deteriorating.
Barley or jau water is high in insoluble fibre, which makes it good for diabetics. It is recommended for diabetics as it helps stabilise blood glucose levels. Make sure you drink unsweetened barley water to get effective results. The antioxidant properties of barley water also helps keep many diseases at bay.
Symptoms of a blood sugar spike may include: frequent urination. fatigue. increased thirst.
Recommended Blood Sugar Targets
Before meals, your blood sugar should be: From 90 to 130 mg/dL (5.0 to 7.2 mmol/L) for adults. From 90 to 130 mg/dL (5.0 to 7.2 mmol/L) for children, 13 to 19 years old. From 90 to 180 mg/dL (5.0 to 10.0 mmol/L) for children, 6 to 12 years old.
A blood sugar level less than 140 mg/dL (7.8 mmol/L) is normal. A reading of more than 200 mg/dL (11.1 mmol/L) after two hours means you have diabetes. A reading between 140 and 199 mg/dL (7.8 mmol/L and 11.0 mmol/L) means you have prediabetes.
If HbA1c is more than 48 mmol/mol or fasting blood glucose is more than 11 mmol/L, your blood sugar is high. For most people without diabetes, normal blood sugar levels are: between 4 and to 6 mmol/L before meals. less than 8 mmol/L two hours after eating.
Symptoms are present and fasting blood test result is at or above 7.0mmol/L or a random blood test result is at or above 11.1mmol/L. HbA1c blood test result is at or above 6.5% (48 mmol/mol) There have been no symptoms and two abnormal blood glucose tests (as above) on separate days.
The dawn phenomenon is an early-morning rise in blood sugar, also called blood glucose, in people with diabetes. The dawn phenomenon leads to high levels of blood sugar, a condition called hyperglycemia. It usually happens between 4 a.m. and 8 a.m.
Fatigue is one of the most common symptoms of high blood sugar. In people with diabetes, it is referred to as diabetes fatigue. Many people with the condition feel tired all the time regardless of how well they sleep, how healthily they eat, or how much they exercise on a regular basis.
