Insulin resistance often develops quietly long before it appears on standard tests. Many people experience unexplained weight gain around the abdomen, intense sugar cravings, persistent fatigue, and occasionally brain fog in the early stages, when the pancreas is compensating by producing extra insulin to keep blood glucose levels within the normal range. Understanding insulin resistance early can make a meaningful difference to long-term health
What is insulin resistance?
Insulin helps move glucose from the bloodstream into cells for energy.When the body becomes resistant, this process is less effective. The body compensates by producing more insulin, sometimes for years before blood sugar levels change.
In early stages, blood glucose can remain normal. This can make routine tests appear reassuring, even when underlying metabolic changes are already present.
Symptoms are often non-specific and easy to overlook, including:
- Increased abdominal circumference (rather than weight)
- Energy fluctuations
- Sugar cravings
Insulin resistance is linked to a range of conditions, including:
- Type 2 diabetes
- PCOS (now known as PMOS)
- Weight-related metabolic changes
- Cardiovascular comorbidities
- Non-alcoholic fatty liver disease
There is no standardised test to objectively quantify insulin resistance, and a normal result does not always rule it out. Assessment often involves looking at patterns, risk factors, and metabolic parameters rather than just a single number.
Identifying insulin resistance early allows for more targeted management and better long-term outcomes, rather than treating symptoms in isolation.
