Let's briefly review how this happens. Certain tissues in the body, such as the lens of the eye, do not require insulin for glucose to enter. Glucose can lazily diffuse into cells in the lens if the level of glucose is high in the surrounding fluid. An enzyme called aldose reductase then converts the glucose into a molecule called sorbitol. This molecule cannot escape from the cells of the lens.
Water is pulled into the cells after it.
This causes the cells to swell, which makes it easier for other molecules, such as sodium, to enter. This swelling and chemical imbalance eventually results in cataracts. Inc. All rights reserved.
