Around one or two out of every hundred people develop an underactive thyroid . This means that your thyroid gland, which sits on the front of the neck, does not produce enough of the hormones that regulate your metabolism.
What does this mean? For people with diabetes, the link relates to metabolism. Underactive thyroid, also known as hypothyroidism, can lead to hunger, low body temperature, muscle weakness and fatigue. Therefore, an underactive thyroid in those with diabetes could also affect blood sugar control.
