Also, a life-threatening consequence of hyperglycemia can be nonketotic hyperosmolar syndrome. [16] Perioperative hyperglycemia has been associated with immunosuppression, increased infections, osmotic diuresis, delayed wound healing, delayed gastric emptying, sympatho-adrenergic stimulation, and increased mortality.
The complications of diabetes can dramatically impair quality of life and cause long-lasting disability. Overall, complications are far less common and less severe in people with well-controlled blood sugar levels. [3] [4] [5] Some non-modifiable risk factors such as age at diabetes onset, type of diabetes, gender, and genetics may influence risk.
Untreated ketoacidosis can rapidly progress to loss of consciousness, coma, and death. [29] The percentage of children whose type 1 diabetes begins with an episode of diabetic ketoacidosis varies widely by geography, as low as 15% in parts of Europe and North America, and as high as 80% in the developing world.
Type 2 diabetes is typically a chronic disease associated with a ten-year-shorter life expectancy. [ 10 ] [ 26 ] This is partly due to a number of complications with which it is associated, including: two to four times the risk of cardiovascular disease, including ischemic heart disease and stroke; a 20-fold increase in lower limb amputations ...
Leading cause of death (2016) (world) The following is a list of the causes of human deaths worldwide for different years arranged by their associated mortality rates. In 2002, there were about 57 million deaths.
If blood sugar levels remain too high the body suppresses appetite over the short term. Long-term hyperglycemia causes many health problems including heart disease, cancer, [25] eye, kidney, and nerve damage. [26] Blood sugar levels above 16.7 mmol/L (300 mg/dL) can cause fatal reactions.
This leads to excessive urination (more specifically an osmotic diuresis), which, in turn, leads to volume depletion and hemoconcentration that causes a further increase in blood glucose level. Ketosis is absent because the presence of some insulin inhibits hormone-sensitive lipase -mediated fat tissue breakdown .
Diabetes can cause acute problems such as too low (hypoglycemia) or high blood sugar (hyperglycemia). Diabetes affects the blood vessels in the body, such as capillaries and arteries, which are the routes blood take to deliver nutrients and oxygen to the organs in the body. [ 4 ]
