Low testosterone can lead to higher diabetes risk

Most people think of type 2 diabetes as a diet and lifestyle issue but in men, low testosterone plays a major role. Men with the lowest free testosterone are 3-4x more likely to have diabetes.

Testosterone therapy helps prevent type 2 diabetes

Prevalence

Men with low testosterone have 4x greater risk of type 2 diabetes

DIAGNOSIS

TRT reduces the risk of developing type 2 diabetes by 41% percent

By restoring healthy testosterone levels, TRT:

  • Reduces visceral fat
  • Enhances energy and motivation
  • Improves insulin sensitivity
  • Weight gain
  • Increases muscle mass
  • Lowers inflammation
  • Supports better blood sugar control
  • Help improve fatigue

Protect your metabolic health for the future

Low testosterone contributes to the conditions that cause diabetes to develop — fat gain, inflammation, poor glucose control — but TRT helps reverse these risk factors early, before they become irreversible.

TRT may also help reverse type 2 diabetes in some men

While the focus of TRT is prevention, it’s worth noting that testosterone therapy has also shown significant benefits in men already living with diabetes.

Diabetes remission
Healthy testosterone levels support blood flow and erectile function, reducing the frequency of ED.
Lower HbA1c levels
Men with poorly controlled diabetes experienced an average drop of 4 mmol/L in HbA1c within 6 months of starting TRT.
Reduced medication
Many men were able to stop using diabetes medications entirely after consistent testosterone treatment.
