Diabetes is a metabolic disease that can lead to a decline in skeletal muscle mass, causing muscle wasting and atrophy. Diabetic amyotrophy, a nerve disorder complication of diabetes mellitus, affects the thighs, hips, buttocks, and legs, resulting in pain and muscle wasting. This condition is believed to arise from an abnormal immune response that damages the tiny blood vessels supplying nerves to the legs. Additionally, diabetes can cause epigenetic changes, altering gene expression and impairing muscle cell regeneration, leading to muscle weakness. Type 2 diabetes, in particular, is associated with reduced muscle strength and impaired glucose uptake by muscles. The link between diabetes and muscle wasting highlights the importance of managing blood sugar levels and incorporating strength and resistance training to maintain muscle health and prevent further complications.

What You'll Learn
Diabetic amyotrophy
The exact cause of diabetic amyotrophy is not yet known, but it is believed to be related to an abnormality of the immune system, resulting in vasculitis with ischemic nerve injury. This damages the tiny blood vessels that supply the nerves to the legs. It is more common in people with type 2 diabetes, typically developing about four years after diagnosis. Being an older man increases the risk, but it can also occur in younger people.
Treatment for diabetic amyotrophy focuses on symptom management and improving the patient's quality of life. Pain relief medications, such as conventional painkillers, neuropathic pain medications, and occasionally stronger painkillers, may be prescribed. Steroid medications have shown some benefit in early use, but their long-term effectiveness is uncertain. Physical therapy can help maintain and improve muscle function, and devices such as reachers and raised toilet seats can aid in comfortable movement. Maintaining tight control over blood sugar levels through medication, diet, and exercise is crucial in managing diabetic amyotrophy.

Muscle atrophy
Diabetes can cause muscle wasting, a condition known as diabetic amyotrophy or diabetic muscular atrophy. Diabetic amyotrophy is a nerve disorder complication of diabetes mellitus, affecting the thighs, hips, buttocks, and legs, and causing pain and muscle wasting. Diabetic muscular atrophy is an unrecognized complication of diabetes that can lead to quadriplegia in severe cases.
The specific activity of Akt kinase in response to insulin was reduced by 34% in patients with T2DM compared to healthy controls. Insulin resistance, which is at least partially derived from systemic inflammation in T2DM and obesity, is a key contributor to muscle atrophy signalling. In T2DM, insulin resistance has been shown to inhibit protein synthesis by inhibiting the IGF-1-PI3K-AKT/PKB-mTOR pathway and to activate the UPS and ALP through the IGF-1-AKT-FoxO signaling pathway, thereby promoting muscle atrophy.
The ubiquitin-proteasome, autophagy-lysosome, and caspase-3-mediated proteolytic pathways are responsible for protein degradation in muscles and thus contribute to muscle atrophy. In healthy muscle, the degradation of damaged or unfolded proteins is vital for maintaining cellular homeostasis. However, in atrophic conditions such as diabetes, prolonged increased activity of these pathways increases the rate of contractile protein degradation, ultimately leading to muscle atrophy.
Research suggests that one reason muscle tissue does not regenerate properly in people with diabetes is that it does not produce enough of a key protein called VPS39. This protein is part of the molecular machinery that cells use to dispose of damaged components in order to regenerate themselves.

Insulin resistance
Diabetes can cause muscle wasting, specifically in the case of diabetic amyotrophy, a nerve disorder complication of diabetes mellitus. Diabetic amyotrophy affects the thighs, hips, buttocks, and legs, causing pain and muscle wasting due to damage to the motor nerve. It is more common in people with type 2 diabetes and tends to last several months but can last up to two years.
Several mechanisms have been proposed to explain the link between insulin resistance and sarcopenia. One mechanism involves increased protein catabolism and decreased protein synthesis in skeletal muscle. Another mechanism is related to the increased expression of the FoxO family, which directly or indirectly attenuates skeletal muscle. Additionally, autophagy in skeletal muscle cells can lead to muscle attenuation. Inadequate intake of amino acids and decreased insulin sensitivity may also contribute to muscle attenuation.
Furthermore, lipid infiltration of myocytes has been implicated in the development of insulin resistance. Increased levels of branched-chain amino acids (BCAA) have been associated with insulin resistance, and BCAA are abundant in skeletal muscle. However, leucine, a type of BCAA, may help reduce muscle wasting by suppressing proteolysis.
While the exact mechanisms are still being investigated, it is clear that insulin resistance plays a significant role in muscle wasting, particularly in the context of sarcopenia and age-related muscle mass loss.

Exercise and muscle regeneration
Exercise is known to promote tissue regeneration and repair in various organs, including skeletal muscle. The protective function of exercise-induced stem cell activation is particularly beneficial under pathological conditions and aging in different organs. Exercise-promoted stem cell activation could be attributed to several factors, such as signaling pathways, oxidative stress, metabolic factors, and non-coding RNAs.
In the context of muscle regeneration, exercise stimulates muscle stem cells (MSCs) to activate and proliferate, initiating the process of myogenesis, where immature muscle cells develop into mature muscle fibers. MSCs are located between the muscle membrane and the basal layer and remain in a quiescent state in adults. Upon muscle injury or exercise stimulation, MSCs are reactivated to facilitate muscle regeneration. The migration of MSCs during tissue regeneration is crucial, as they can migrate between muscle fibers to repair damage and replenish the stem cell pool.
The duration of exercise and factors such as age play a significant role in the effectiveness of exercise-induced muscular regeneration. Additionally, exercise can promote muscle regeneration through various molecular mechanisms, including the activation of regenerative inflammation via AMPK signaling.
While exercise is beneficial for muscle regeneration, it is important to consider the volume, intensity, and duration of workouts, as these factors impact the recovery time needed. Proper nutrition, hydration, and adequate sleep are also essential for muscle recovery. Consuming protein after a workout helps repair muscle damage, and certain supplements, such as creatine, can aid in reducing muscle damage and inflammation.

Skeletal muscle mass decline
Diabetes can cause epigenetic changes in genes, altering their expression and preventing the production of certain proteins. For example, in people with type 2 diabetes, the VPS39 gene may be silenced, hindering the production of the VPS39 protein. This protein is crucial for autophagy, the process by which cells dispose of damaged components to regenerate themselves. Without sufficient VPS39, muscle stem cells may remain immature or break down and die, leading to impaired muscle regeneration and atrophy.
Additionally, type 2 diabetes impairs the ability of muscles to take up glucose and utilise it for energy production. This can result in reduced muscle strength and endurance. The condition diabetic amyotrophy further complicates this issue, causing muscle wasting and pain in the thighs, hips, buttocks, and legs due to nerve damage.
The risk of skeletal muscle mass decline can be mitigated through lifestyle modifications such as progressive resistance-based strength training and a healthy diet rich in protein. These interventions can help improve strength, rebuild muscle mass, and slow down the progression of sarcopenia. However, it is important to consult with a healthcare professional before embarking on any new exercise or dietary regimen.
While sarcopenia is typically associated with ageing, it can also affect younger individuals with certain risk factors, such as physical inactivity, unhealthy diet, and chronic diseases. The interaction of these factors with the natural ageing process contributes to the development and progression of skeletal muscle mass decline.

Frequently asked questions
Muscle wasting, or atrophy, is the loss of muscle bulk.
Yes, diabetes can cause muscle wasting. This is more common in people with type 2 diabetes. Diabetic amyotrophy is a nerve disorder complication of diabetes mellitus that causes muscle wasting in the thighs, hips, buttocks and legs.
Diabetes is caused by insufficient action of the hormone insulin, which lowers blood sugar levels. Insulin also promotes the growth and proliferation of cells, so its insufficient action results in the suppression of growth and proliferation of muscle cells, contributing to muscle wasting.
Muscle wasting can be treated with pain relief, steroids, and other medications. It is also important to keep muscles working as much as possible to minimise wasting.
