The Connection Between Type 2 Diabetes and Middle Age

Both forms of diabetes mean for a significant change in habits and a much more accurate estimation of current health, and can be developed at any age.

Type 2 diabetes usually appears after age 40 and research has shown that there is a much higher incidence of people being diagnosed with type 2 diabetes once they’ve lived to middle age.

After a diagnosis, the patient will have to carefully monitor their cholesterol levels, blood glucose, as well as their blood pressure. Typically, insulin itself, as a form of treatment, won’t be necessary. It’s reserved only for hospital visits or extreme circumstances such as pregnancy.

What exactly contributes to people only showing symptoms until they’re in their forties? Well, there are a few contributing factors that are thought to be the culprits:

Obesity and Sedentary Lifestyle

Those who lack consistent physical activity in their lives, especially those to the point where a person becomes overweight, are considered to be at significant risk of developing type 2 diabetes.

The extra weight has a correlation with increased levels of insulin resistance, which will eventually result in an individual going to their doctor and getting put on medication for diabetes.

This happens later in age because the body begins to not function as properly as well, as a general decrease in physical activity associated with aging.

Insulin Resistance

The starting point for type 2 diabetes is the phenomenon of insulin resistance. Many cells in the body, including and not limited to the liver, muscle, and fat cells don’t properly make use of insulin which is key in extracting and storing glucose from the carbohydrates we eat.

It begins with the pancreas creating more insulin to compensate, but eventually, it can no longer meet the demand. At this point, blood sugar levels become much more challenging to manage. This happens over time, so logically, it can be expected to occur more in middle-aged populations.


Of course, genetics plays a significant role in whether or not someone is likely to develop type 2 diabetes. A family history of diabetes (type 1 or 2) is indicative you’re at risk, but not necessarily a guarantee you’ll develop the condition.

Many conditions that occur more often in life can be directly tied to someone’s genetic makeup. This is because by middle age, it’s highly likely for the average human being to have passed on their genetic makeup, meaning there’s less evolutionary pressure on being extremely physically fit into the later years.


Carefully understanding the health implications of your age group is vital for being ready for the future. It gives you an idea of what to look out for and what questions to be asked to your doctor.

Some steps can be taken to reduce the chances you’ll develop type 2 diabetes, such as maintaining a healthy diet and exercising regularly. The evidence on hand strongly suggests that a person is most likely to be diagnosed with type 2 diabetes later in life.
