Hyperglycemia, or high blood sugar, is a common complication of diabetes that can have devastating effects on the body if left unmanaged. When glucose levels are elevated for extended periods, it can damage organs and tissues throughout the body.
The Silent Damage to Kidneys: A Consequence of Chronic Hyperglycemia
Chronic hyperglycemia has been linked to an increased risk of kidney disease and failure. High blood sugar damages the small blood vessels in the kidneys, impairing their ability to filter waste from the blood. According to a study published in the Journal of Clinical Endocrinology and Metabolism, individuals with diabetes are 15-20 times more likely to develop end-stage renal disease (ESRD) than those without diabetes.
The Impact on Nervous System Function: Neuropathy and Hyperglycemia
Hyperglycemia can also damage the nerves that carry signals between the brain and other parts of the body, leading to a condition known as diabetic neuropathy. This type of nerve damage is irreversible and can cause chronic pain, numbness, and weakness in affected areas.
The Link Between High Blood Sugar and Heart Health: A Deadly Combination
High blood sugar levels have been linked to an increased risk of cardiovascular disease, including heart attacks, strokes, and high blood pressure. Hyperglycemia damages the inner lining of blood vessels, leading to inflammation and atherosclerosis (hardening of the arteries). According to the American Diabetes Association, individuals with diabetes are at least 2-4 times more likely to die from heart disease or stroke than those without diabetes.
The Effects on Vision: A Threat to Eye Health
Hyperglycemia can also damage the blood vessels in the retina and lens of the eye, leading to vision loss. Prolonged exposure to high blood sugar levels increases the risk of diabetic retinopathy, a common complication that affects millions worldwide. According to the National Eye Institute, diabetes is the leading cause of blindness among adults aged 20-74.
The Consequences for Skin and Wound Healing: A Delayed Recovery
Hyperglycemia impairs wound healing by reducing blood flow to affected areas and delaying recovery times. High glucose levels also increase oxidative stress, which can lead to skin complications such as acne, ulcers, and foot infections. According to a study published in the Journal of Clinical Biochemistry and Nutrition, uncontrolled hyperglycemia is associated with increased morbidity and mortality from surgical procedures.
The Impact on Mental Health: A Closer Look at Cognitive Decline
Lastly, chronic hyperglycemia has been linked to cognitive decline, including memory loss, confusion, and dementia. High blood sugar levels can damage the brain's ability to regulate glucose metabolism, leading to impaired cognitive function. According to a study published in the Journal of Alzheimer's Disease, individuals with diabetes are at increased risk for developing neurodegenerative diseases such as Alzheimer's.
Hyperglycemia is a serious condition that demands attention and management. By understanding its effects on various organs and systems, we can better appreciate the importance of maintaining healthy blood sugar levels through lifestyle modifications, medication adherence, and regular monitoring.
HbA1c is a blood test used for measuring the effects of glucose on your body. In this short video, one of Australia’s leading authorities explains how it is used in diagnosing and monitoring diabetes type 2. HbA1c measures the percentage of haemoglobin in your blood that has been affected by glucose. It is a particularly useful test because as it is reflecting the process of the more widespread tissue damage that is occurring. As you can imagine, if glucose sticks to proteins like glucose fasting blood sugar haemoglobin, it is also sticking to other proteins in your body and causing damage. A good way of thinking about the effect of glucose on your body is to compare it with the way sugar becomes caramelised when heated – the sugar sticks together to make toffee. This is what happens when glucose sticks to apple watch series 7 blood sugar haemoglobin. When someone has a glucose test, this only shows the level of glucose in their blood which is present at that moment in time and the circumstances might mean that it is particularly high or low for a temporary reason. An HbA1c test shows the average glucose damage levels over the previous four months and therefore provides a much more even estimation of a person’s situation. The HbA1c test is not affected by diet or exercise and therefore you do not need to fast before giving a sample. Whether you're having your HbA1c test for the diagnosis of diabetes or to manage it, you don't need to have procedure of blood sugar test the test more than once every four months.
