Injection sites
“It’s important to choose injection sites wisely during the summer,” says Magdalena Szkudlinska, MD, an endocrinologist specializing in diabetes and thyroid disorders at Pacific Medical Centers in Seattle. “Heat causes blood vessels to increase in size and insulin may be absorbed faster. This can put an individual with diabetes at risk of having low blood sugar,” says Dr. Szkudlinska. You should cool off for 20 minutes before injecting.
