Understanding Deadly Blood Sugar Levels: Causes, Consequences, and Prevention
The ideal blood sugar range is a delicate balance that plays a crucial role in maintaining overall health. However, when left unmanaged, high or low blood sugar levels can have severe consequences on the body.
Blood Sugar Fluctuations: A Double-Edged Sword High and low blood sugar fluctuations can be detrimental to one's health. When blood glucose levels spike above 180mg/dL (milligrams per deciliter), it puts additional strain on the pancreas, leading to insulin resistance. This chronic condition increases the risk of developing type 2 diabetes, cardiovascular disease, and even cognitive impairment.
On the other hand, consistently low blood sugar can lead to hypoglycemic episodes that cause shakiness, dizziness, and in severe cases, loss of consciousness. Furthermore, prolonged periods of hypoglycemia have been linked to an increased risk of heart attacks and strokes.
The Science Behind Insulin Resistance Insulin sensitivity plays a vital role in maintaining healthy blood sugar levels. When insulin binds to receptors on the surface of cells, it signals them to absorb glucose from the bloodstream for energy production or storage. However, when these receptors become desensitized due to repeated exposure to high insulin levels (insulin resistance), they can no longer effectively uptake glucose.
As a result, blood sugar builds up in the bloodstream, exacerbating fluctuations and putting further strain on pancreatic function. Exercise is an essential component of maintaining insulin sensitivity as it enhances muscle cell responsiveness to insulin, thus promoting better glucose absorption.
Dietary Management: A Key Factor The food we consume significantly influences our blood sugar levels. Consuming foods with a high glycemic index (GI) such as white bread and sugary drinks rapidly spikes blood glucose, exacerbating fluctuations. Conversely, eating more fiber-rich fruits and vegetables reduces the rate of digestion and absorption, providing sustained energy.
It's also essential to include lean protein sources like fish in our diet as they help stabilize insulin sensitivity over time. Furthermore, restricting portion sizes can prevent sudden surges in blood sugar levels that come with excessive carbohydrate intake.
Stress Management: A Hidden Factor While exercise is known for its stress-reducing benefits, high intensity workouts or lack of physical activity can have the opposite effect if not managed carefully. Stress causes our bodies to release cortisol, a hormone released from the adrenal glands in response to perceived threats (real or imagined). Cortisol has been shown to suppress insulin function and stimulate gluconeogenesis – a natural process that generates glucose from non-carbohydrate sources.
Tracking Blood Sugar: The Key to Balance Monitoring blood sugar levels is vital for maintaining balance. For those without diabetes, tracking can begin with daily monitoring using glucometers or continuous glucose monitors (CGM). When used in conjunction with dietary and exercise strategies, these tools help develop an understanding of fluctuations that would otherwise remain hidden.
Regular self-assessment allows us to pinpoint patterns such as blood sugar spikes post-mealtime meals. Understanding this pattern can aid in meal planning by adjusting the time and type of food consumed to minimize subsequent surges.
Preventing Deadly Blood Sugar Levels: The Road Ahead With a comprehensive understanding of how factors like diet, exercise, stress management, and sleep quality contribute to fluctuating blood sugar levels – it's clear that making lifestyle adjustments is paramount in maintaining optimal health. Incorporating regular monitoring into daily life allows for the detection of early warning signs before they escalate into more severe complications.
By committing to healthy choices such as balanced eating habits and moderate physical activity along with adequate stress management, individuals can take proactive steps towards achieving a stable blood sugar range that's less susceptible to deadly fluctuations.
In the first of a four-part series, Anne Peters, MD, explains why diagnosing diabetes isn't necessarily easy. -- TRANSCRIPT -- This is the first in a series of videos in which I'm discussing how to diagnose diabetes. In the past, when I trained, it seemed splenda blood sugar levels as though this was simple. First, there were people who didn't have diabetes. There were people with type 1 diabetes who basically had an absolute deficiency of insulin. Then there were people with type 2 diabetes who both didn't make enough insulin and also had insulin resistance. The world was simple. We treated those types of diabetes differently and there wasn't much confusion. There's also prediabetes, which I'm not discussing, and both pre–type 2 diabetes and pre–type 1 diabetes. Ideally, we'd prevent people from developing overt diabetes if we diagnosed them earlier. The American blood sugar level how to increase Diabetes Association Standards of Care classifies diabetes in this way. First, they say type 1 diabetes is due to autoimmune beta-cell destruction, usually leading to absolute insulin deficiency. This includes latent autoimmune diabetes of adulthood (LADA). LADA is a form of type 1. I think there's subtlety here because there are people with type 1 who don't have measurable autoantibodies. There are people with LADA who are treated much like they have type 2 diabetes, at least for a while. We know from the Joslin 50-year follow-up study that people with type 1 diabetes after 50 or more years may still make a little bit of measurable C-peptide. In theory, type 1 diabetes is autoimmune beta-cell destruction that leads to insulin deficiency. Type 2 diabetes is due to a non-autoimmune, progressive loss of adequate beta-cell insulin secretion, frequently on the background of insulin resistance and metabolic syndrome. I'm going to point out that metabolic syndrome can occur in anybody, and I have many patients with type 1 diabetes who also have metabolic syndrome. I think that's a separate issue for many of our patients, but it's very important because it confers a higher risk for cardiovascular disease. Then there are subtypes of diabetes due to other causes. Frankly, these are the patients that I see most often. There are patients who have monogenic diabetes syndromes such as neonatal diabetes and maturity-onset diabetes of the young (MODY); diseases of the exocrine pancreas such as cystic fibrosis and pancreatitis; patients who are post-pancreatectomy; patients who have drug or chemically induced diabetes, such as with glucocorticoid 38 blood sugar level use; people who are treated for HIV/AIDS; and those who have organ transplants. There is gestational diabetes, which is diabetes diagnosed in the second or third trimester of pregnancy that was not present prior to the pregnancy and tends to go away after the pregnancy but confers an increased risk for type 2 diabetes in the future. Almost everything we do depends on the patient's clinical status and how they respond to treatment, not necessarily just based on a label. There is no single specific test that separates people with type 1 diabetes from type 2 diabetes. Islet autoantibodies can be present in every type of diabetes, from type 1 diabetes to type 2 diabetes to MODY. There are people with type 1 diabetes who don't have measurable insulin autoantibodies.
