Recent research indicates that high blood glucose is an important risk

This study included non-critically ill patients hospitalized with COVID-19 (Carrasco-Sánchez F, et al., 2021).

11,312 patients were categorized into three groups according to their blood glucose levels: Less than 140 mg/dL, between 140-180 mg/dL and more than 180 mg/dL. Only 2128 of these patients had diabetes.

This is what the researchers found. 20.4% of the patients died during hospitalization.

The in-hospital mortality rates were 15.7% for patients with blood glucose levels of less than 140 mg/dL, 33.7% for patients with levels between 140-180 mg and 41.1% for patients with blood glucose levels of more than 180 mg/dL.

High blood glucose levels were also associated with requirements for mechanical ventilation and intensive care admission.

High blood glucose levels regardless of a prior history of diabetes was a strong predictor of all-cause mortality.

A high nutrient, low glycemic index diet is important to keep your blood glucose at a low level.

You can also use berberine, a plant compound, which has been found to lower blood glucose and provide many other health benefits as well (Zhang Y, et al., 2008).
