Many people view diabetes as a problem of eating too many sweets leading to high blood sugar levels. Diabetes is not caused by eating sugar alone, but is a consequence of multiple reasons. These include:
Non-Modifiable Factors
Some conditions that predispose to diabetes cannot be altered. People with these conditions should undergo regular screening so that the diabetes can be detected and treated soon after it develops. These include:
- Genetic predisposition: Diabetes can be genetic. Patients often have parents or other close relatives already diagnosed with diabetes.
- Autoimmunity: The immune system mistakenly attacks and damages the insulin-producing beta cells of the pancreas, thereby reducing the insulin levels and causing diabetes.
- Older age: Natural aging leads to changes that could increase blood glucose levels.
Such people are advised to follow healthy lifestyles to reduce the risk of developing diabetes.
Lifestyle & Behavioral Factors
Daily habits dictate how effectively muscles clear glucose from the bloodstream and the secretion of hormones that could affect blood glucose levels. For example:
- Sedentary Behavior: Inactivity prevents muscles from actively taking up glucose from the blood, causing baseline levels to rise. Inadequate exercise may result in insufficient muscle mass, which in turn lowers the capacity to clear circulating glucose.
- Ultra-Processed, High-Glycemic Index Diets: Foods high in refined starches and stripped of fiber increase the need for insulin. Diet could also alter the gut microbiome, which in turn could predispose to diabetes.
- Chronic Sleep Deprivation and Psychological Stress: Inadequate sleep and persistent stress releases hormones that increase blood glucose levels.
These conditions can easily be controlled through changes in lifestyle changes, thereby preventing diabetes.
Health Disorders
Certain health conditions could also predispose to diabetes. These include:
- Visceral Adiposity: Fat accumulation around internal abdominal organs secretes pro-inflammatory signals that trigger insulin resistance, thereby increasing blood glucose levels.
- Metabolic Liver Disease (MASLD): Fat accumulation in the liver in MASLD (Metabolic Dysfunction-Associated Steatotic Liver Disease) impairs the liver’s ability to regulate fasting glucose levels.
- Hormonal Imbalances: Conditions like Polycystic Ovary Syndrome (PCOS) alter cause hormonal changes which may affect blood sugar levels. .
- Medication Intake: Medications such as certain antipsychotics or steroids can elevate blood sugar as a side effect.
Identification and treatment of these conditions as well as replacing medications that increase the blood glucose levels could help in reducing the risk of developing diabetes.
Clinical Takeaway
Diabetes is rarely the result of a single dietary choice like eating sugar. While non-modifiable genetic and biological factors cannot be avoided, the onset and progression of diabetes are often dependent on lifestyle practices, and in some cases, underlying illnesses.
Effective diabetes management goes far beyond cutting sweets—it centers on expanding muscle mass through resistance exercise, prioritizing healthy lifestyles, and treating underlying conditions that could predispose to diabetes.
