Regularly having high blood sugar levels for long periods of time (over months or years) can result in permanent damage to parts of the body such as the eyes, nerves, kidneys and blood vessels. If you experience hyperglycaemia regularly, speak to your doctor or diabetes care team.
High blood sugar over time damages blood vessels in the brain that carry oxygen-rich blood. When your brain receives too little blood, brain cells can die. This is called brain atrophy and can cause problems with memory and thinking and eventually can lead to vascular dementia.
“Post-meal blood sugars of 140 mg/dl [milligrams per deciliter] and higher, and fasting blood sugars over 100 mg/dl [can] cause permanent organ damage and cause diabetes to progress,” Ruhl writes.
Extreme thirst. Light-headedness. Flushed, hot, dry skin. Restlessness, drowsiness, or difficulty waking up.
Complications of Diabetes
If type 2 diabetes goes untreated, the high blood sugar can affect various cells and organs in the body. Complications include kidney damage, often leading to dialysis, eye damage, which could result in blindness, or an increased risk for heart disease or stroke.
People With Diabetes Can Live Longer by Meeting Their Treatment Goals. Life expectancy can be increased by 3 years or in some cases as much as 10 years. At age 50, life expectancy- the number of years a person is expected to live- is 6 years shorter for people with type 2 diabetes than for people without it.
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.
If your blood sugar level is slightly high for a short time, emergency treatment won't be necessary. But if it continues to rise you may need to act fast to avoid developing diabetic ketoacidosis (DKA). If your blood sugar level is 15 mmol/l or more, you should check your blood or urine for ketones.
The American Diabetes Association (ADA) and American Association of Clinical Endocrinologists (AACE) consensus on inpatient hyperglycemia defined stress hyperglycemia or hospital-related hyperglycemia as any blood glucose concentration >140 mg/dl (>7.8 mmol/l) in patients without a prior history of diabetes (15,16).
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.
How long does it take for kidneys to become affected? Almost all patients with Type I diabetes develop some evidence of functional change in the kidneys within two to five years of the diagnosis. About 30 to 40 percent progress to more serious kidney disease, usually within about 10 to 30 years.
A diabetic coma could happen when your blood sugar gets too high -- 600 milligrams per deciliter (mg/dL) or more -- causing you to become very dehydrated. The problems that high blood sugar can cause happen over time.
Symptoms of uncontrolled diabetes include extreme fatigue, frequent urination, excessive thirst or hunger, unintended weight loss, and blurred vision.
High blood glucose levels can affect the brain's functional connectivity, which links brain regions that share functional properties, and brain matter. It can cause the brain to atrophy or shrink.
Patients with diabetes have been found to have several changes in brain structure that appear to develop over time (top) and often experience conditions that present risk for subsequent cognitive dysfunction (bottom).
A reading above 300 mg/dL can be dangerous, according to the University of Michigan, which recommends immediately informing your doctor if you have two or more readings of 300 mg/dL in a row. In severe cases, very high blood sugar levels (well above 300 mg/dL) can result in coma.
Target blood sugar levels differ for everyone, but generally speaking: if you monitor yourself at home – a normal target is 4-7mmol/l before eating and under 8.5-9mmol/l two hours after a meal. if you're tested every few months – a normal target is below 48mmol/mol (or 6.5% on the older measurement scale)
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.
Skipping Meals
Skipping a meal can cause you to have high blood glucose levels, so don't skip a meal in an attempt to lower high blood sugar.
When people eat food the food breaks down into sugars which is only stored with the help of insulin. if insulin is not produced adequately then it is stored in the blood stream rising a person's blood glucose levels.
A. No, zero sugar soda uses artificial sweeteners, which increases people's weight. Increased weight, in turn, is linked to the worsening of diabetes. Hence, zero soda is not suitable for diabetes.
Diabetes Life Expectancy
The average life expectancy of a type 2 diabetic patient is between 77 to 81 years. However, it is not uncommon for diabetics to live past the age of 85, should they be able to maintain good blood sugar levels and lengthen their lifespan.
