Pre-diabetes – understanding risk factors and taking early action
Dear Patients,
Prediabetes refers to a metabolic condition in which blood sugar regulation is already impaired, but the diagnostic criteria for overt diabetes have not yet been met. Since classic laboratory values may still be within the normal range, this condition often goes undetected.
Early detection of risk factors is therefore crucial.
Genetic and family history
A family history of diabetes significantly increases the risk. Genetic factors influence both the insulin production of beta cells and the insulin sensitivity of the body’s cells. The distribution of body fat is also partly genetically determined and can have a long-term impact on the metabolic situation.
Body fat distribution and visceral obesity
Body fat distribution and visceral obesity
It is not only body weight that is decisive, but above all the distribution of fat. Visceral fat in the abdominal cavity is hormonally active and releases pro-inflammatory messenger substances. These can impair insulin action and contribute to the development of insulin resistance.
The combination of increased fat mass and reduced muscle mass is particularly unfavourable, as the muscles are a central site of glucose utilisation.
Insulin resistance and early beta cell dysfunction early beta cell dysfunction
Disorders affecting insulin action can occur years before diabetes manifests itself. At the same time, the ability of beta cells to produce sufficient insulin can gradually decline. These processes are often asymptomatic, but significantly increase long-term risk.
Subtypes of prediabetes – not all have the same risk
Current scientific concepts distinguish between several subtypes of prediabetes, which differ significantly in terms of pathophysiology and risk of progression.
Low-risk groups
Despite being overweight, some of those affected have a stable metabolic status with good insulin sensitivity and predominantly subcutaneous fat distribution. Metabolically healthy slim people with high insulin sensitivity also belong to these groups. The risk of rapid progression to type 2 diabetes is comparatively low here.
High-risk groups
Other subtypes show a significantly increased risk:
-
Pre-diabetes with fatty liver
pronounced fatty liver, severe insulin resistance and early beta cell dysfunction. -
Pre-diabetes with beta cell failure
Here, reduced insulin secretion and impaired glucose tolerance are the main features. -
Slow Progressors with hyperinsulinism
Visceral obesity and chronically elevated insulin levels, sometimes with early organ damage, even though glucose levels are only moderately elevated.
This differentiation illustrates that it is not only the blood sugar level that is decisive, but also the underlying metabolic pattern.
Inflammatory processes and metabolic markers
Chronic, low-grade inflammatory processes are closely related to impaired glucose regulation. Various metabolic markers can provide early indications of increasing insulin resistance or an incipient metabolic disorder.
Lifestyle and age
The most important modifiable factors include:
- unbalanced diet,
- lack of exercise
- high sugar consumption
- excessive alcohol consumption
- smoking
With increasing age, insulin sensitivity decreases physiologically, which means that existing risk factors can have a greater impact.
Hormonal factors and comorbidities
Women who suffer from gestational diabetes or polycystic ovary syndrome are at increased risk of developing glucose disorders later in life. Hormonal changes during the menopause can also influence metabolic processes.
High blood pressure, lipid metabolism disorders and non-alcoholic fatty liver disease are often associated with prediabetes and further increase the risk.
Prediabetes in adolescence
Glucose metabolism disorders are increasingly evident in adolescence, especially in overweight or obese individuals. Early onset of overweight significantly increases the risk of metabolic comorbidities and the development of diabetes.
Social and socio-economic factors also play a role, as they can affect diet, exercise and access to preventive services.
Prevention through differentiated diagnostics
At the Alpstein Clinic, risk factors are not considered in isolation. In addition to classic laboratory values, parameters such as body composition, muscle mass, fat distribution and insulin sensitivity are also included in the assessment.
The aim is to identify individual risk patterns at an early stage and to influence them in a targeted manner through structured dietary adjustments, exercise strategies and metabolic optimisation.

We look forward to meeting you in person
We would be happy to advise you personally at the Alpstein Clinic to analyse your individual metabolic risk and discuss suitable preventive measures.
