A diabetic coma is a life-threatening condition that can occur when blood sugar levels become severely elevated or plummet. To understand the risk of diabetic coma, it's essential to know what blood sugar levels are considered critical.
Normal Blood Sugar Range
The American Diabetes Association recommends the following normal blood sugar ranges: 80-130 mg/dL (milligrams per deciliter) before meals and less than 180 mg/dL after meals. However, these numbers can vary depending on individual factors such as age, weight, and activity level.
Critical Blood Sugar Levels
While diabetic coma is a rare occurrence, blood sugar levels above or below the normal range can still have serious consequences. If left untreated, severely high blood sugar (hyperglycemia) or low blood sugar (hypoglycemia) can lead to diabetic ketoacidosis, coma, and even death.
Hyperglycemic Emergencies
Blood glucose levels of 300 mg/dL or higher are considered hyperglycemic emergencies. At this level, the body produces high amounts of ketones, which can cause seizures, confusion, and eventually a coma.
Causes of Hyperglycemia
Several factors can contribute to hyperglycemia in people with diabetes. These include:
- Insulin deficiency or resistance
- Inadequate food intake
- Increased stress levels
- Certain medications
Hypoglycemic Emergencies
Conversely, low blood sugar (hypoglycemia) is a condition that can occur when the body produces too much insulin. Blood glucose levels below 50 mg/dL are considered hypoglycemic emergencies.
Causes of Hypoglycemia
Hypoglycemia in people with diabetes can be caused by:
- Inadequate food intake
- Excessive exercise or physical activity
- Certain medications, such as sulfonylureas and meglitinides
Managing Blood Sugar Levels to Prevent Diabetic Coma
Preventing diabetic coma requires careful blood sugar management. This involves monitoring blood glucose levels regularly, adjusting medication regimens accordingly, and maintaining a healthy lifestyle.
Healthy Lifestyle Choices
In addition to medication adjustment, adopting a healthy diet and regular exercise routine can help regulate blood sugar levels.
By understanding what critical blood sugar levels are and taking proactive steps to manage them, individuals with diabetes can minimize the risk of diabetic coma.
Dr. Trindade explains that obesity, prediabetes, and/or diabetes are all clinical manifestations of insulin 110 mg/dl blood sugar level resistance. She will explore patient history, lack of sleep, heavy metals, blood sugar to low symptoms microbiome, hormonal imbalances, infections, nutrient deficiencies, prescriptions drugs, and genetic predispositions to find the underlying cause of insulin resistance.
