Is diabetes contagious?

Diabetes can be said to be one of the most common diseases nowadays. Most diabetic patients may be obese or middle-aged and elderly, and people with a family history of diabetes may also be one of the high-risk groups. Diabetes has a certain degree of heredity, so some people who don’t understand it will ask, is diabetes contagious? Diabetes is not contagious, but many cases of diabetes are hereditary.

Diabetes experts tell us: There are currently two main types of diabetes: type 1 and type 2. However, no matter which type it is, there is currently no case or evidence to prove that diabetes is contagious, so diabetes is not contagious.

Experts explained: The current clinical manifestations of diabetes are generally 1. Polydipsia, polyuria, polyphagia and weight loss. Severe hyperglycemia causes typical symptoms of "three mores and one less", which are more common in type 1 diabetes. The symptoms of "three more and one less" are more obvious when ketosis or ketoacidosis occurs. 2. Fatigue and obesity are common in type 2 diabetes. Type 2 diabetes often precedes obesity, and if it is not diagnosed promptly, weight loss will occur gradually.

If someone has diabetes, there are only two possible causes: genetic factors and environmental factors:

1. Genetic factors: There is obvious genetic heterogeneity in both type 1 and type 2 diabetes. Diabetes has a familial tendency, with 1/4 to 1/2 of patients having a family history of diabetes. Clinically, there are at least 60 genetic syndromes that may be associated with diabetes. There are multiple DNA sites involved in the pathogenesis of type 1 diabetes, among which the DQ site polymorphism in the HLA antigen gene is the most closely related. Many clear gene mutations have been found in type 2 diabetes, such as the insulin gene, insulin receptor gene, glucokinase gene, mitochondrial gene, etc.

2. Environmental factors: Obesity caused by overeating and reduced physical activity is the most important environmental factor for type 2 diabetes, making individuals with a genetic susceptibility to type 2 diabetes more susceptible to the disease. Patients with type 1 diabetes have abnormal immune systems, which can lead to autoimmune reactions and damage to insulin beta cells after being infected by certain viruses such as coxsackie virus, rubella virus, and mumps virus.

The above is a brief introduction to diabetes by diabetes experts and a simple analysis of common diseases. It tells you the causes of diabetes. It is certain that it has nothing to do with genetics. Don’t worry that diabetes will be inherited. Don’t scare yourself. Have a healthy and good attitude and don’t be troubled by simple questions such as whether diabetes can be inherited.
