Understanding the Connection Between Viral Infections and Diabetes

Diabetes affects over 500 million people worldwide, with approximately two million individuals living with the condition in one country alone. Even more concerning is the number of pre-diabetic individuals—those with elevated blood sugar levels but not yet diagnosed with diabetes, bringing the total affected population to nearly six million. These insights were shared by Dr. Iván Escobar, an experienced endocrinologist, during an interview.

Dr. Escobar explained that there are two main types of diabetes. Type 1 diabetes is an autoimmune disease most commonly diagnosed in children and adolescents, while Type 2 diabetes usually affects adults dealing with overweight or obesity, often linked to poor diet and sedentary lifestyles. Symptoms include increased thirst, frequent urination, fatigue, weakness, and weight loss. A simple blood glucose test helps diagnose diabetes: levels of 126 mg/dL or higher indicate diabetes, while readings between 100 and 125 mg/dL suggest a pre-diabetic state.

Type 2 diabetes often comes with additional health concerns such as hypertension, abnormal cholesterol levels, coronary disease, and increased risk of stroke. Poorly managed diabetes may lead to serious complications like kidney failure requiring dialysis or transplant, and diabetic retinopathy, a leading cause of blindness worldwide.

Gestational diabetes is another form that appears during pregnancy, typically in the third trimester. It resembles Type 2 diabetes but is temporary. Without proper management, however, it can increase the risk of developing permanent diabetes later in life. Proper diet and exercise are key preventive measures.

Regarding heredity, babies are not born with diabetes, but children of diabetic mothers require monitoring for blood sugar issues shortly after birth. If a parent has Type 1 diabetes, the risk for the child varies between 3% and 6%. In cases where one parent has Type 2 diabetes, lifestyle factors during pregnancy such as diet and alcohol consumption can impact the child’s health.

Dr. Escobar also highlighted recent studies exploring how certain viral infections might influence the onset of diabetes. Some treatments involving corticosteroids can induce diabetes-like symptoms, while viruses may potentially damage the insulin-producing cells in the pancreas.

Individuals with diabetes often experience chronic inflammation, which can compromise their immune response. This inflammation, combined with other health risks, can increase vulnerability to severe illness.
