You can live for years with untreated type 2 diabetes, as symptoms often develop slowly, but high blood sugar eventually causes severe complications like heart disease, kidney failure, blindness, or nerve damage, significantly shortening life expectancy, potentially by several years to over a decade depending on diagnosis age and management, though proper treatment can greatly improve longevity. Untreated, diabetes becomes a life-limiting illness, with cardiovascular issues being the leading cause of death, but managing blood sugar, blood pressure, and cholesterol can add years back to your life.
3.5 Synthesis of results
In T2D, men had an estimated life expectancy of 74.34 years (95%CI: 72.81–75.87; I2 = 100.00; τ²=39.15; PI = 61.32 to 87.28), while women lived 79.63 years (95%CI: 78.32–80.95; I2 = 100.00; τ²=29.44; PI = 68.36 to 90.83) (p < 0.001 for the difference) (Supplementary Appendix p.
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.
Stage 5: End-Stage Diabetes
At this point, oral medications may no longer be effective, and insulin therapy becomes necessary for survival. This stage is also characterized by advanced complications, which might include kidney failure requiring dialysis or severe heart conditions.
Cardiovascular disease (CVD), where the heart and blood vessels are negatively impacted, is the number one cause of death in people living with diabetes, resulting in twice as many deaths in people with diabetes than those without.
EMERGENCY – You are in the danger zone if you have:
Blood glucose that is still less than 4 mmol/L after 3 attempts to treat low blood sugar. Blood glucose that is greater than 20 mmol/L for more than 8 hours and you are symptomatic (if you have Type 2 Diabetes).
Symptoms of type 2 diabetes
This could result in low blood glucose levels (hypoglycaemia) . You must also bring your blood glucose meter and diabetes medications with you on treatment days . It is important that you try and avoid skipping any meals so we suggest you come prepared by bringing snacks and drinks with you .
Type 2 diabetes progresses through four stages: Insulin Resistance, where cells don't use insulin well; Prediabetes, with elevated but not diabetic blood sugar; Type 2 Diabetes, characterized by overt high blood sugar and potential symptoms; and finally, Vascular Complications, involving damage to blood vessels and organs from prolonged high glucose. This continuum highlights the importance of early intervention to slow progression and manage the disease.
Diabetes can damage your eyes, heart, nerves, feet, and kidneys due to high blood sugar. Manage diabetes with a proper plan to protect these vital organs. Diabetes is a serious disease that can affect your eyes, heart, nerves, feet and kidneys.
Type 2 diabetes increases an individual's risk of a range of complications including heart attack and stroke, kidney problems, and cancer.
Symptoms and Causes
There's no cure for diabetes and no way to completely get rid of it. However, diabetes can be reversed in most people. Reversing diabetes means carefully managing blood sugars to a point where medications are no longer necessary, and staying at that manageable point through a healthy routine of diet and exercise.
Feeling very thirsty. Feeling very hungry—even though you are eating. Extreme fatigue. Blurry vision.
The “three-hour rule” for rapid-acting insulin (aka "Insulin Stacking") Rapid-acting insulin begins to work about 15 minutes after injection, peaks in about 1 hour, and continues to work for 2 to 4 hours. The three-hour rule prevents “insulin stacking” and a low blood glucose (BG) or hypoglycemia.
Indeed, myocardial infarction is the leading cause of death among individuals with diabetes mellitus.
Fasting can cause blood sugar crashes.
Fasting of any type increases the risk of extremely low blood sugar, also known as hypoglycemia, in people who have Type 2 diabetes. The safety and effectiveness of any weight-loss plan are unique to each person.
If you notice the following symptoms, make an appointment to get care: Being very thirsty. Urinating often. Being much more tired than usual.
As you age, you're more likely to have multiple medical conditions, including high blood pressure and high cholesterol. That can make it harder for you to keep your diabetes under control. In turn, diabetes can lead to other health problems such as heart disease.
8 Sneaky Signs Your Diabetes Is Getting Worse
Losing weight can reverse type 2 diabetes, but is rarely achieved or recorded. Type 2 diabetes is generally perceived as progressive and incurable, but for many patients it can be reversed with sustained weight loss of around 15 kg, say experts in The BMJ today.
When to Go to the ER for Diabetes. If you have diabetes, certain symptoms might indicate your condition is spiraling into a crisis: Severe Hypoglycemia (Low Blood Sugar) Signs include confusion, blurred vision, fainting, or seizures. Left untreated, hypoglycemia can be life-threatening.
Normal blood sugar v. high blood sugar
A blood sugar of 100 mg/dL or higher is considered abnormal. A range of 100-125 mg/dL falls under the category of prediabetes, while a blood sugar of 126 mg/dL or higher is considered type 2 diabetes. At least two abnormal blood sugar test results are needed to make a diagnosis.
