Hypoglycaemia (too low blood sugar) is rare in people who don’t have diabetes. The brain relies on a constant supply of glucose to function optimally and there are mechanisms in place that ensure certain level of glucose is always maintained.
Lipohypertrophy is largely due to the local lipogenic effects of insulin. It is a common side effect of subcutaneous insulin therapy, occurring in up to 50% of people with type 1 diabetes.
