Insulin Resistance - What causes it?

Updated: Apr 4, 2023



Insulin resistance occurs when cells in the body become less responsive to the effects of insulin, leading to higher levels of insulin in the blood.

The exact cause of insulin resistance is not fully understood, but there are several factors that can contribute to its development.


Genetics: Insulin resistance can run in families and may be inherited through genes that affect insulin signaling pathways.


Obesity: Excess body fat, particularly abdominal fat, can contribute to insulin resistance by increasing inflammation in the body and interfering with insulin signaling.


Sedentary lifestyle: Lack of physical activity can lead to decreased insulin sensitivity and contribute to insulin resistance.


Unhealthy diet: A diet high in processed and sugary foods can increase insulin resistance, particularly when combined with a sedentary lifestyle.


Aging: As we age, our bodies may become less responsive to insulin, contributing to insulin resistance.


Sleep deprivation: Lack of sleep or poor sleep quality can lead to hormonal imbalances and increase insulin resistance.


Chronic stress: Prolonged stress can lead to the release of stress hormones, which can interfere with insulin signaling and contribute to insulin resistance.


Low vitamin D: Some studies suggest that chronically low vitamin D levels can contribute to insulin resistance. We get this vitamin from the sun mainly and is used for many processes in the body including, hormone regulation.
