A blood sugar level of 900 is significantly higher than the normal range, indicating a serious imbalance in your body's glucose regulation. This condition can lead to various complications if left unmanaged.
The ideal blood sugar range varies depending on several factors such as age, sex, and overall health status. However, generally speaking, for non-diabetic individuals, the fasting plasma glucose (FPG) levels should be between 70-99 mg/dL. For diabetic patients, managing their blood sugar within a target range is crucial to preventing complications.
When your body produces more insulin than it needs or becomes resistant to its effects, excess glucose builds up in the bloodstream, causing high blood sugar levels. In people with diabetes, factors like inadequate medication management and lifestyle choices can lead to elevated fasting plasma glucose (FPG) readings exceeding 180 mg/dL, while those without a diagnosis are at risk of insulin resistance and type-2 diabetes if they consistently record an FPG value over 140 mg/dL.
Maintaining a healthy blood sugar range involves regular monitoring through finger prick testing with glucometers or continuous glucose monitors (CGMs), especially in individuals managing their condition. These devices offer real-time insights into fluctuations, guiding better decision-making about food and medication intake.
Causes of Extremely High Blood Sugar Levels: Understanding the Science
There are several factors contributing to high blood sugar readings like 900:
- Insulin resistance: When cells become less responsive to insulin's effects, your body releases more glucose in an attempt to overcome this impairment. This process causes fasting plasma glucose levels and post-meal spikes (1-hour PPGL values) to rise substantially.
- Dietary choices: Consuming high-carb meals without matching fiber intake or not balancing macronutrient distribution throughout the day will increase blood sugar after consumption, particularly when combined with poor sleep hygiene practices.
Why Extreme Blood Sugar Spikes Are a Concern: The Risks Involved
Blood sugar spikes pose several risks to your overall health:
- Kidney strain: High glucose levels put unnecessary pressure on kidney function over time.
- Nerve damage (diabetic neuropathy): Uncontrolled blood sugar elevations raise the risk of permanent nerve impairment, impacting mobility and sensation.
A fasting plasma glucose value at or above 126 mg/dL confirms diabetes diagnosis according to guidelines from international authorities like ADA.
I answer some common questions I’ve been asked about cholesterol and diabetes. What is the ideal LDL level? How can I reduce insulin resistance?
