Causes and Risk Factors
Another myth is that stress leads to diabetes. This again is not true. But stress can affect the immune system which can trigger type 2 diabetes. Besides, stress can aggravate the existing symptoms in someone with diabetes.
Type 2 diabetes is caused when:-
► The body receptors that respond to insulin fail to do so (insulin resistance). This may send the wrong signal to the insulin-producing pancreatic cells, which produce excessive insulin
► The insulin that is produced is abnormal and is therefore substandard and non- functional
► There is not enough insulin available
Risk Factors include -
► Increasing age
► Fairly inactive lifestyle –exercise fewer than 3 times a week
