According to reports, diabetes can happen in really early age of one person. For the type one diabetes, the youngest diabetes patient ages 2 months. And the type 2 diabetic patient ages 4 years old.
Diabetes, according to the etiology, generally has 4 major categories. Different types of diabetes happen in different ages.
1.Type 1 diabetes (T1DM)
T1DM features an absolute lack of insulin out of beta cell destruction.
: acute type and delayed type. Most of the patients are between 15 to 20 years old. Typical cases occur among children or adolescents. Patients over 40 years are tiny minority.
Acute type usually happens in the early age, and the youngest patient was only 1 years old. Delayed type mostly occurs in adolescence, even midlife.
: no evidence of autoimmunity. This type happens at an early age.
2.Type 2 diabetes mellitus (T2DM)
T2DM is the type of diabetes that most of us are familiar with. It features
from insulin resistance mainly with insufficient insulin secretion to insufficient insulin secretion accompanied by insulin resistance.
T2DM can occur at any age, but more commonly seen in adults over 40.
3.Other special types of diabetes
1). Gene defects of beta cell function:
① diabetes mellitus in young adults:
so far 6 subtypes have been found, respectively due to different genetic mutations.
It happens during the youth and the onset of age is less than 25 years of age.
② mitochondrial diabetes mellitus:
the onset age spans widely but less than 45 years old.
2) Gene defect of insulin action:
This type is generally linked with genetic. It can happen in fetal stage, making highly possible premature, stillbirth and early death.
There are: Type A insulin resistance, Donohue syndrome, Rabson-mendenhall syndrome, Berardinell-Seip syndrome, etc.
3) External secretion of pancreatic diseases:
It generally occurs along with other diseases after being an adult, including pancreatitis, traumatic/pancreatic resection, tumor, cystic fibrosis (mainly in the infancy stage), hemochromatosis (often occurs in the elderly especially the female over 50 years old), fibrous calcified pancreatic disease (mainly happens in the male under 30), protein-deficient pancreatic diabetes (mainly happens under 35), etc.
4) Endocrine diseases:
It usually happens in the youth in the form of complications of other diseases, mainly including limb hypertrophy, Cushing's syndrome, glucagon tumor, Pheochromocytoma, hyperthyroidism, somatostatin tumor, aldosterone tumor and so on.
5) Diabetes caused by drugs or chemicals.
Age of onset here is relative to the medicine you take and its dose, such as
Metronidazole (Vacor, a poison rat), nicotinic acid, glucocorticoid, thyroid hormone, nitrogen, Â adrenaline receptor agonist, piperazine diuretic, phenytoin sodium, á-interferon, etc.
4. Gestational diabetes Mellitus (GDM)
Any kind of glucose tolerance abnormalities found during pregnancy can be defined as GDM.
If you have been diagnosed as diabetes before pregnancy, you can be called the "diabetes combined with pregnancy".
The risk of gestational diabetes mellitus in pregnant women aged 40 years and over is 8.2 times of pregnant women aged between 20 to 30 years old.
Now we take age of 30 and over as high paroxysmal age for GDM.
