According to physician researchers with The Ohio State University College of Medicine, increased levels of the hormone aldosterone, already associated with hypertension can leads to development of diabetes. Aldosterone is produced by the adrenal gland, it increases blood pressure, insulin resistance in muscle and impairs insulin secretion from the pancreas.
These increase the risk of developing type 2 diabetes, researchers followed 1,600 people across diverse populations for 10 years as part of the Multi-Ethnic Study of Atherosclerosis. They found, overall, the risk of developing type 2 diabetes more than doubled for people who had higher levels of aldosterone, compared to participants with lower levels of the hormone.
In certain ethnicities, the effect was even greater. African Americans with high aldosterone levels have almost a three-fold increased risk. Chinese Americans with high aldosterone are 10 times more likely to develop diabetes. High levels of aldosterone contributed to hypertension, it might also be linked to diabetes.
There are wide differences in risk among various ethnic groups, this could be genetics or differences in salt sensitivity. According to the Centers for Disease Control and Prevention, over 30 million Americans have diabetes and nearly a fourth of them don’t know it. One in three Americans has prediabetes.
