Muscle loss in the legs can be caused by several factors, including age, genetics, nutrition, and physical activity levels. Age-related muscle loss, known as sarcopenia, commonly affects older adults and is characterized by a decrease in muscle mass and strength. This can lead to difficulties in performing daily activities such as walking, climbing stairs, and carrying groceries. Genetic disorders such as muscular dystrophy can also cause muscle loss by affecting the genes responsible for protein production, resulting in weaker muscles and loss of muscle mass over time. Inactivity and sedentary lifestyles contribute to muscle loss, as the body breaks down unused muscles to conserve energy. Additionally, inadequate nutrition, particularly a lack of lean protein, fruits, and vegetables, can impair muscle growth and maintenance, leading to muscle atrophy.

Sedentary lifestyle
Muscle atrophy, or the wasting or thinning of muscle mass, can be caused by a sedentary lifestyle. This is known as physiologic atrophy, or disuse atrophy, and is the result of not using muscles enough. When muscles are not in use, the body breaks them down, causing a decrease in muscle size and strength. This can happen to anyone and any muscle in the body, and the speed at which atrophy occurs depends on the individual. However, it can happen very quickly, even within a couple of weeks.
A poor-quality diet can also contribute to muscle loss. A low intake of protein is suspected to be a contributing factor, as the body has increasing difficulty turning protein into energy as it ages. Therefore, increasing protein intake through food or supplements is recommended to help reverse muscle atrophy.
Age-related muscle loss, or sarcopenia, is a natural part of the aging process and can begin as early as one's thirties or forties. It becomes more noticeable around age sixty, and it is estimated that between 5% and 13% of people aged 60 to 70 are affected. Sarcopenia can be a serious problem, impacting one's quality of life by reducing the ability to perform daily tasks. It can also increase the risk of falls, broken bones, disability, and death.
While sarcopenia is primarily caused by aging, inactivity can significantly increase the risk. Staying active as one ages can reduce the risk of sarcopenia, and even help to reverse its effects. Progressive resistance-based strength training is recommended by healthcare providers, as it can help improve strength and reverse muscle loss.

Malnutrition
Age-related hormonal changes, such as decreased testosterone and insulin-like growth factor (IGF-1) production, can also contribute to muscle atrophy in older adults. Sarcopenia, a type of muscle atrophy, is common among older adults and is characterized by a progressive loss of muscle mass and strength, leading to functional decline and an increased risk of falls and fractures.
In addition to malnutrition, muscle atrophy can also be caused by the disuse of muscles, neurogenic conditions, genetic factors, and certain medical conditions. Diagnosing muscle atrophy involves a physical exam, symptom discussion, and various tests, such as blood tests, muscle biopsies, and imaging scans. Treatment options include exercise, physical therapy, functional electric stimulation, and surgery.

Neurogenic conditions
Neurogenic atrophy or neurogenic muscle loss is caused by an injury or a neurogenic condition. It is the wasting or thinning of muscle mass. Neuromuscular disorders are conditions that affect the nerve, muscle, or neuromuscular junction (where the nerve communicates with the muscle).
Muscular dystrophy is a group of inherited diseases that cause weakness and wasting away of muscle tissue. There are multiple types of muscular dystrophy, each leading to a loss of strength, increasing disability, and possible deformity. The most common types are Duchenne and Becker muscular dystrophy.
Myasthenia gravis (MG) is a neuromuscular disorder that causes weakness in voluntary skeletal muscles. It can affect people of any age but is more common in females under 40 and males over 60. There is no cure for MG, but early treatment can help improve muscle weakness.
Amyotrophic lateral sclerosis (ALS), or Lou Gehrig's disease, is a progressive neurological disease that damages motor nerve cells and often begins with muscle twitching and leg weakness. There is currently no cure for ALS, but treatments are available to help control symptoms and improve quality of life.
Guillain-Barré syndrome (GBS) is a rare autoimmune disorder in which the immune system attacks the nerves, causing tingling and weakness that usually begins in the feet and legs. The weakness can spread quickly and eventually paralyze the entire body if left untreated.

Genetic factors
Muscle atrophy, or muscle wasting, is the loss of muscle mass. It can be caused by several factors, including genetic disorders such as muscular dystrophy.
Muscular dystrophy is a group of inherited diseases that cause muscles to become weaker and lose mass over time. It occurs when one of the genes involved in protein production mutates. There are over 30 types of muscular dystrophy, and symptoms vary depending on the type. The most common type is Duchenne muscular dystrophy, which mostly affects boys in childhood. Other types include Becker muscular dystrophy, which tends to be milder and starts in the teens or early adulthood, and Emery-Dreifuss muscular dystrophy, which often affects the muscles in the shoulders, upper arms, and calves. Limb-girdle muscular dystrophy often affects the muscles around the shoulders and hips and can lead to serious trouble using arms or legs for everyday activities. Facioscapulohumeral muscular dystrophy (FSHD) usually starts with muscle weakness in the face, shoulders, and upper arms, often affecting one side of the body more than the other. Myotonic muscular dystrophy causes muscles to be unable to relax at will, and can later lead to heart rhythm issues and weaker breathing muscles.
Muscular dystrophy can be treated with medicines and other interventions to manage symptoms and slow the progression of the disease. However, there is currently no cure for this genetic disorder that leads to muscle loss.
Other genetic factors that can contribute to muscle loss include sarcopenia, a condition that commonly affects older adults due to the body producing fewer proteins that promote muscle growth. This condition can also affect people with a high body mass index (BMI) in a form called sarcopenic obesity. While aging is the dominant factor in sarcopenia, other risk factors include physical inactivity, a poor diet, and chronic diseases such as COPD, kidney disease, diabetes, cancer, or HIV. Treatment for sarcopenia includes progressive resistance-based strength training and a healthy diet with increased protein intake.

Ageing
Muscle loss in the legs is a common problem for older people. This is due to the natural ageing process, which causes muscle atrophy or a decrease in muscle mass and strength. The medical term for this is sarcopenia, which is rare before the age of 60. However, the process of losing muscle begins much earlier, with most people starting to lose muscle mass and strength in their 30s or 40s.
As people age, they tend to become less active, which causes a reduction in muscle strength. This inactivity can be due to a more sedentary lifestyle or other factors such as illness or injury. The less people move their bodies, the more their muscles atrophy or shrink, which makes the weakness worse over time. This can become a vicious cycle, as weak leg muscles can lead to a higher risk of falls and injuries, which may further reduce a person's ability to be active.
Hormonal changes that occur with ageing also contribute to muscle loss. For example, changes in testosterone and insulin-like growth factor (IGF-1) can affect muscle fibres. Additionally, the body's ability to produce the proteins needed for muscle growth decreases with age. A poor diet, particularly one lacking in sufficient calories, protein, vitamins and minerals, can also contribute to muscle loss in older people.
The good news is that there are ways to prevent and treat age-related muscle loss in the legs. Staying physically active is key, with resistance exercises such as squats, push-ups, sit-ups, and leg presses being particularly effective. It's also important to include aerobic exercise, such as walking, to build endurance and improve overall health. In addition to exercise, eating a healthy diet that includes enough calories and high-quality protein can help slow down muscle loss. Omega-3 and creatine supplements may also be beneficial.
