Why diabetics should absolutely keep an eye on their testosterone levels

In today's blog post, we'll shed light on a crucial aspect that often gets overlooked in standard diabetes treatments: the link between type 2 diabetes and testosterone levels. A balanced testosterone level plays a vital role in men's well-being, but it can be significantly disrupted by type 2 diabetes and other comorbidities (Putta et al., 2017) . A resulting testosterone deficiency can have serious consequences and is often associated with symptoms that go beyond the typical signs of diabetes (Walther et al., 2019) . Today, we'll explain how testosterone levels and type 2 diabetes are connected, why this common condition often leads to testosterone deficiency in men, and what steps can be taken to address these challenges. This post provides valuable insights and practical tips to raise awareness of the importance of monitoring testosterone levels in men with diabetes—a topic of high priority at Adon Health.

Type 2 diabetes: A brief overview

Type 2 diabetes, one of the most widespread chronic diseases, is primarily characterized by insulin resistance and insufficient insulin secretion. This metabolic disorder results in the body's inability to effectively regulate blood sugar. In the short term, elevated blood sugar levels can cause symptoms such as fatigue, increased thirst, frequent urination, and blurred vision. These signs should be considered early warning signals indicating the need for medical evaluation. In the long term, untreated type 2 diabetes carries the risk of causing serious damage to various body systems. Damage to blood vessels, a central problem in this disease, can lead to complications affecting the nerves, eyes, cardiovascular system, kidneys, and reproductive organs. These long-term effects underscore the importance of early diagnosis and continuous management of type 2 diabetes (Kannel & McGee, 1979) .

It is therefore crucial to be informed about the symptoms and treatment options for type 2 diabetes and to adopt a lifestyle that helps control blood sugar levels. Regular medical monitoring, a balanced diet, regular physical activity, and, if necessary, medication play an important role in managing this disease.

The link between type 2 diabetes and testosterone deficiency

A crucial, yet often overlooked, aspect of type 2 diabetes is its link to hypogonadism in men, a condition characterized by low testosterone levels. Men with type 2 diabetes show a high prevalence of hypogonadism, up to 50% (Rao et al., 2013) . This association between testosterone deficiency and type 2 diabetes warrants particular attention, as testosterone deficiency not only impairs quality of life but is also associated with specific metabolic problems such as abdominal obesity, insulin resistance, and lipid metabolism disorders—all key components of metabolic syndrome.

Metabolic syndrome is a cluster of conditions that, in addition to insulin resistance and central obesity, often includes elevated blood lipid levels, high blood pressure, and elevated blood glucose levels. The presence of testosterone deficiency in men with type 2 diabetes can increase the risk for these conditions and often exacerbates the severity of metabolic syndrome. This syndrome, in turn, increases the risk of further health complications, including cardiovascular disease and stroke. Interestingly, low testosterone levels can directly contribute to the development of obesity by affecting fat distribution and leading to the accumulation of visceral fat (Wittert et al., 2003) . This visceral fat is particularly metabolically active and contributes to increased production of inflammatory markers, which in turn promote insulin resistance. Thus, a vicious cycle is created in which testosterone deficiency exacerbates metabolic syndrome, which in turn increases the symptoms and risks of type 2 diabetes.

Studies, including research published in the prestigious journal "Diabetes Care," have shown that low testosterone levels in men with type 2 diabetes are significantly associated with this metabolic disorder (Stellato et al., 2000) . This finding is particularly relevant because testosterone plays a crucial role in glucose metabolism. Low testosterone levels can impair insulin sensitivity and thus exacerbate the symptoms of type 2 diabetes. Understanding this interaction is essential for the effective treatment and management of type 2 diabetes (Traish et al., 2009) . It underscores the need for a holistic approach that considers both blood glucose levels and hormonal balance. Monitoring and adjusting testosterone levels can therefore be an essential component of a comprehensive diabetes management plan.

In this context, Adon Health offers comprehensive information and support to help men with type 2 diabetes find and maintain balance in their hormonal and metabolic systems. By integrating modern treatment approaches and a deep understanding of the specific challenges faced by men with type 2 diabetes, Adon Health aims to raise awareness of this important aspect of men's health and offer practical solutions.

The effects of testosterone replacement therapy (TRT)

In the world of men's health, testosterone replacement therapy (TRT) represents a significant treatment option for men with type 2 diabetes who suffer from hypogonadism and low testosterone. Interestingly, research shows that TRT can not only normalize testosterone levels but also plays an important role in regulating glucose metabolism (Kato et al., 2019) . In men with hypogonadism and type 2 diabetes, TRT has been shown to reduce insulin resistance, decrease waist circumference, and improve blood glucose control. The TIMES2 study, in particular, highlights how TRT can significantly reduce insulin resistance and have positive effects on cholesterol, especially LDL cholesterol, over a six-month period. An improvement in sexual health was also observed.

These findings are particularly relevant because they highlight the interactions between type 2 diabetes, testosterone deficiency, and cardiovascular risk factors. The results of the TIMES2 study support the effectiveness of TRT as part of a comprehensive treatment plan for men with type 2 diabetes and testosterone deficiency (Jones et al., 2011) .

Further recent research findings, particularly the T4DM study (Testosterone for Diabetes Mellitus) published in renowned scientific journals, have yielded impressive results. They demonstrate that testosterone therapy in individuals with prediabetes and low testosterone levels can effectively help prevent the development of type 2 diabetes or even reverse the early stages of the disease (Wittert et al., 2021) . These findings represent a significant advance in diabetes research and offer new hope for a more effective prevention strategy against this widespread chronic disease.

Adon Health recognizes the importance of this treatment option and promotes awareness and understanding of the benefits of such therapy. Our goal is to provide men with the information and support they need to make informed decisions about their health and treatment options, particularly in the context of diabetes and low testosterone.

Recommendations for action for men with type 2 diabetes

At Adon Health, we understand the challenges men with type 2 diabetes face in their daily lives. Therefore, we want to provide practical recommendations that take both medical and lifestyle aspects into account.

‍

Medical monitoring and consultation

1. Regular medical check-ups: It is important to consult an endocrinologist regularly to monitor the progression of your diabetes and keep an eye on your testosterone levels .
2. Individual treatment plans: Discuss with your doctor whether testosterone replacement therapy is appropriate in your specific case.

‍

Nutrition management

1. Balanced macronutrient distribution: Ensure a balanced intake of proteins, fats, and carbohydrates. Research shows that a diet rich in unsaturated fatty acids, moderate in protein, and low in sugar can have a positive effect on blood sugar levels (Abdelhafiz & Sinclair, 2015) .
2. Important micronutrients: Include foods rich in zinc (Netter et al., 1981) and vitamin D, as these are important for testosterone production (Allen & Key, 2000) . Supplementing your diet with these nutrients can also be considered.

‍

Physical activity

1. Strength and endurance training: Combine regular strength training with aerobic exercises. Studies show that such a combination can not only improve insulin sensitivity but also positively influence testosterone levels (Pitteloud et al., 2005) .
2. Customized training: Work with a physiotherapist or certified trainer to develop a program tailored to your individual health needs and goals.

‍

Stress management

1. Mind-body techniques: Integrate practices like yoga or meditation into your daily routine to reduce stress. Research shows that such techniques can help lower cortisol levels (Xiong et al., 2021) , which in turn can positively influence testosterone levels (Gothe et al., 2016) .
2. Sufficient sleep: Make sure you get enough sleep, as sleep deprivation can negatively affect both blood sugar levels and hormone balance. Research shows that a lack of sleep, especially a reduction in REM sleep phases, can lead to a decrease in testosterone levels (Agrawal et al., 2022) .

‍

Implementation in everyday life

1. Support networks: Build a network of family, friends, and like-minded people who support you in your lifestyle .
2. Self-monitoring: Keep a journal to record your progress, diet, and physical activity. This can help boost your motivation and make adjustments.
