Type 2 diabetes is a metabolic disease that affects the body's ability to regulate blood sugar levels. One of the complications associated with this condition is muscle weakness, which can significantly impact a person's quality of life and ability to perform daily tasks. This is a late complication of diabetes and is often associated with diabetic neuropathy, amyotrophy, and sarcopenia. Diabetic neuropathy is a nerve disorder that can cause pain, tingling, and weakness in the hands and feet, while amyotrophy leads to muscle wasting and sarcopenia results in a progressive loss of skeletal muscle mass. The interplay between these conditions and type 2 diabetes can lead to muscle weakness, and understanding this relationship is crucial for managing the condition and improving patients' overall health and well-being.

Diabetic neuropathy
Type 2 diabetes can cause muscle weakness, which is often associated with diabetic neuropathy. Diabetic neuropathy is nerve damage caused by high blood sugar levels, affecting the feet and other areas of the body. Peripheral neuropathy is the most common form, causing pain, numbness, and loss of feeling in the toes, feet, legs, hands, and arms. It can also lead to muscle weakness and loss of reflexes, particularly at the ankle, resulting in changes in gait.
Diabetic peripheral neuropathy (DPN) is characterised by symmetrical sensorimotor polyneuropathy, resulting from chronic hyperglycaemia and cardiovascular risk factors. DPN causes significant skeletal muscle function decline, with a greater fibre density in the dorsiflexor muscles and a reduction in motor neurons, leading to muscle weakness, atrophy, and intramuscular fatty infiltration.
Proximal neuropathy affects the thighs, hips, buttocks, or legs, causing serious pain and weak and shrinking thigh muscles. It can also lead to difficulty rising from a sitting position. Focal neuropathy, on the other hand, affects specific nerves, typically in the head, torso, or leg, and can cause sudden weakness or pain in a single nerve or a group of nerves.
The presence of muscle weakness in type 2 diabetes is often determined through clinical scores, nerve conduction studies, and quantitative sensory testing, which provide a neuropathy rank-sum score (NRSS). Type 2 diabetic patients may exhibit muscle weakness at the ankle and knee, correlating with the presence and severity of peripheral neuropathy.
It is important to note that diabetic neuropathy is often preventable, and screening tests can help detect it early for more effective treatment. Managing blood sugar levels and adopting a healthy lifestyle can also reduce the risk of nerve damage and associated muscle weakness in individuals with type 2 diabetes.

Insulin resistance
Skeletal muscle is the largest insulin-sensitive tissue in the body and plays a crucial role in glucose clearance and metabolism. Insulin resistance in skeletal muscle is manifested by decreased insulin-stimulated glucose uptake. This disruption in glucose uptake can lead to a delay in insulin action and overall diminished glucose uptake by the skeletal muscle, contributing to muscle weakness.
Additionally, diabetes-related fatigue can contribute to muscle weakness. Diabetes-related fatigue can be influenced by physiological, psychological, and lifestyle factors. It can lead to a reduction in muscle strength and quality, resulting in muscle fatigue and a decreased work capacity, further exacerbating muscle weakness.

Frailty and sarcopenia
Diabetes is associated with an increased risk of physical disability in older adults. Older people with diabetes have lower muscle mass and weaker muscle strength. In addition, muscle quality is poorer in diabetic patients.
Sarcopenia is a syndrome characterised by a progressive and generalised loss of skeletal muscle mass with either muscle weakness or poor physical performance. Frailty is a state of increased vulnerability to minor stressors due to decreased physiological reserve in multiple organ systems, which increases the risk of poor health outcomes, including falls, hospitalisation, disability, and death.
Diabetes-related fatigue can lead to frailty, including self-reported exhaustion, low physical activity, slow walk speed, low grip strength, and weight loss, which further increases the risk of falls. Additionally, physiological, psychological, and lifestyle factors can contribute to diabetes-related fatigue and subsequent frailty.
Interventions targeting sarcopenia and frailty in older adults with diabetes are crucial for preventing adverse health outcomes. Early detection, physical exercise, and nutrition education can help manage these conditions and improve health outcomes.

Motor impairment
Lord et al. found impaired muscle strength of knee extension in a group of aged female type 2 diabetes patients. Additionally, type 2 diabetes patients showed a 17% reduction in strength of ankle flexors and a 14% reduction in strength of ankle extensors. At the knee, the strength of extensors and flexors was reduced by 7% and 14%, respectively. These findings indicate that type 2 diabetes patients may experience muscle weakness and impaired motor performance in the lower body.
The cause of motor impairment in type 2 diabetes patients is often attributed to neuropathy, specifically diabetic polyneuropathy, which affects the nerves in the feet, legs, hands, and arms. This can lead to a loss of feeling, tingling, burning sensations, pain, and muscle weakness. Diabetic amyotrophy, a type of nerve disorder, is another complication that affects the thighs, hips, buttocks, and legs, resulting in pain and muscle wasting.
The risk of motor impairment and associated complications increases with the duration of diabetes and poor metabolic control. Additionally, uncontrolled high blood sugar can damage nerves and interfere with their ability to send signals, further contributing to neuropathy and muscle weakness.
The management of motor impairment and frailty in type 2 diabetes patients should focus on sarcopenia prevention, which involves assessing functional status and screening for sarcopenia and frailty. Early interventions based on physical exercise and nutrition education can help improve muscle strength and delay the progression of muscle weakness.

Diabetic amyotrophy
The symptoms of diabetic amyotrophy typically start suddenly on one side of the body and may spread to the other side over time. The initial pain can last for several weeks to months, and the weakness can continue to progress even after the pain has improved. In severe cases, individuals may experience difficulty walking without assistance. Other symptoms include unexplained weight loss, paraplegia, and arreflexia.
The treatment for diabetic amyotrophy focuses on symptom management and improving the patient's quality of life. Keeping blood sugar under control through medication, diet, and exercise is crucial. Pain relief medications, such as gabapentin and pregabalin, can help manage nerve-related pain. Physical therapy can also be beneficial in maintaining and improving muscle strength and function. In some cases, early use of immunomodulators, such as steroids, may be proposed as a superior therapy.
It is important to note that diabetic amyotrophy is distinct from other types of diabetic neuropathy, which typically affect the legs and feet. Diabetic amyotrophy can also involve the chest and abdomen, and its symptoms, such as foot drop, are unique. Diagnosis of diabetic amyotrophy is based on clinically suggestive findings in recently diagnosed diabetic patients, and additional laboratory and diagnostic studies may be warranted to exclude other likely etiologies.

Frequently asked questions
Yes, type 2 diabetes can cause muscle weakness. Diabetic patients had a 17% reduction in strength of ankle flexors and a 14% reduction in strength of ankle extensors. At the knee, strength was reduced by 7% in extensors and 14% in flexors.
There are three main factors that contribute to muscle weakness in type 2 diabetes: physiological factors, psychological factors, and lifestyle factors. Physiological factors include acute or chronic hypo- or hyperglycemia, blood glucose variability, and diabetes symptom distress. Psychological factors include depression, emotional distress related to diabetes, sleep disturbances, and restless leg syndrome. Lifestyle factors include sedentary behavior, weight control issues, and obese sarcopenia.
The symptoms of diabetic neuropathy include loss of feeling or numbness, a tingling or burning feeling, sharp pains or cramps, muscle weakness, and digestive, urinary, or sexual dysfunction.
Treatment for muscle weakness in type 2 diabetes focuses on managing frailty and preventing sarcopenia through physical exercise and nutrition education. Screening for sarcopenia is recommended for older adults with diabetes to promote early interventions.
