People without diabetes but with slightly higher blood sugar levels have a higher risk of becoming seriously ill from Covid-19 than people with diabetes.
In a recent paper published in the journal Primary Care Diabetes, scientists revealed that people who do not have diabetes but have mildly elevated blood sugar levels have a higher risk of developing diabetes. According to the British medical journal News Medical, Covid-19 is more severe than people with diabetes.
In other words, people with slightly higher blood sugar may have an increased risk of contracting Covid-19.
Diabetes is known to be one of the main underlying diseases that increase the risk of severe Covid-19 infection.
High blood sugar levels can weaken the immune system’s ability to fight off invading pathogens, viruses and bacteria. Conversely, bacteria also induce insulin resistance and raise blood sugar levels by increasing the secretion of pro-inflammatory cytokines and stress hormones.
In the new study, scientists from Tehran Medical University (Iran) compared the severity of Covid-19 infection in pre-diabetic and non-diabetic patients. With or without mild hyperglycemia.
The study was conducted on 822 hospitalized Covid-19 patients. They were divided into the following 3 groups based on blood glucose levels at admission:
315 people had diabetes.
394 people did not have diabetes but had normal blood sugar levels.
113 people did not have diabetes but had slightly higher blood sugar – above 140 mg/dL.
Preliminary results suggest that Covid-19 patients with diabetes have significantly higher mortality, intensive care unit (ICU) stay and length of stay.
Most surprisingly, however, people without diabetes but with slightly elevated blood sugar levels (above 140 mg/dL) had significantly higher rates of Covid-19 mortality and ICU-free morbidity compared to those with disease . Diabetic patients, according to Medical News.
Although diabetes increased mortality and ICU admissions in Covid-19 patients, the increase was surprisingly lower than in people without diabetes but with slightly elevated blood sugar levels (above 140 mg/dl).
In addition, the study also showed that Covid-19 patients with blood glucose levels below 140 mg/dl had significantly lower length of hospital stay, ICU stay and mortality.
Based on these findings, scientists believe that mild hyperglycemia (over 140 mg/dL) can be considered a predictor of severe Covid-19 disease, News Medicine reported.
