Muscle atrophy is a condition where muscles waste away or lose tissue, causing weakness and loss of muscle mass. It can be caused by several factors, including lack of physical activity, malnutrition, ageing, genetics, nerve problems, or underlying medical conditions. The good news is that in many cases of muscle atrophy, specific exercises combined with a proper diet and lifestyle changes can help build muscle back up. This paragraph will explore the causes of muscle atrophy and provide an introduction to loosening and rebuilding atrophied muscles.

Reversing disuse atrophy with exercise
Disuse atrophy, also known as physiologic atrophy, is caused by not using muscles regularly or at a high enough level of exertion. This can be due to a sedentary lifestyle, malnourishment, a medical condition, or old age. In many cases, disuse atrophy can be reversed through regular exercise and improved nutrition.
If you suspect you are experiencing muscle atrophy, it is important to consult a medical professional for a proper diagnosis and treatment plan. They may recommend physical therapy or an exercise plan tailored to your needs, which can include exercises in a swimming pool to reduce muscle workload. Working with a personal trainer can also help increase attendance, tolerance, and enjoyment of resistance exercises.
To build up atrophied muscles, specific exercises such as leg raises, squats, and push-ups can be performed. These exercises target key muscle groups such as the quadriceps, hip flexors, hamstrings, and glutes, helping to improve mobility and balance. Additionally, nutritional supplements and increased protein intake can aid in muscle recovery and growth.
It is important to note that the treatment for muscle atrophy depends on the type and severity of the condition. While disuse atrophy can often be reversed with exercise and a healthy diet, neurogenic atrophy, caused by nerve damage, may require additional treatment such as electrical stimulation or ultrasound therapy.

Reversing disuse atrophy with diet
Muscle atrophy is the thinning or wasting of muscle tissue and muscle mass. It can be caused by a lack of physical activity, age, genetics, malnutrition, or certain medical conditions. Disuse atrophy occurs when muscles are not used enough, and neurogenic atrophy is caused by nerve problems or diseases.
Disuse atrophy can often be reversed with exercise and a healthy diet. A healthy diet, combined with specific exercises, can help to rebuild muscle memory and increase muscle mass. It is important to consult a doctor or healthcare provider before starting any muscle-building program, as they may refer you to a qualified trainer or physical therapist. They may also recommend working with a dietitian to develop a healthy eating plan.
To build atrophied muscles, it is important to ensure adequate carbohydrate intake. Carbohydrates should make up about 45 to 65 percent of your total calorie intake. Good sources of carbohydrates include fruits and vegetables, whole grains, plain yogurt, and milk. These foods provide carbohydrates that are high in fiber and low in added sugars.
In addition to carbohydrates, including good fats in your diet can help to stop the breakdown of muscle. Omega-3 fatty acids, for example, interfere with the inflammatory process, preventing muscle breakdown.
Supplementing with proteins and amino acids may also aid in muscle recovery. Whey proteins, in particular, have been shown to prevent immobilization-induced atrophy in animal studies. However, it is important to note that dietary protein supplementation alone may not be sufficient to limit muscle mass loss.

Treating neurogenic atrophy
Neurogenic atrophy is the most severe type of muscle atrophy. It is caused by an injury or disease affecting the nerves that connect to the muscles. When these nerves are damaged, they cannot trigger the muscle contractions needed to stimulate muscle activity. As a result, the muscles do not contract, and the body starts breaking them down, leading to a decrease in muscle size and strength.
Diseases and conditions that can affect these nerves include:
- Amyotrophic lateral sclerosis (ALS)
- Guillain-Barre syndrome
- Carpal tunnel syndrome
- Spinal cord injury
- Multiple sclerosis
- Polio
- Muscular dystrophy
Neurogenic atrophy typically cannot be reversed due to the physical damage to the nerves. However, treatment options are available to manage the condition. These include:
- Physical therapy: Exercise therapy is the most effective treatment for neurogenic atrophy. Working out in a swimming pool can reduce the muscle workload during rehabilitation. For those who cannot move certain joints, exercises can be performed with braces or splints.
- Electrical stimulation: A special kind of physical therapy called electrical stimulation can be used to treat neurogenic atrophy.
- Ultrasound therapy: This non-invasive therapy uses sound waves to promote tissue healing and reduce inflammation.
- Surgery: In some cases, surgery may be required to correct a contracture.
- Drug treatment: Traditional Chinese medicine, chemical drugs, antioxidants, enzyme and enzyme inhibitors, and hormone drugs are some options that can be explored.
- Gene therapy: This approach targets the underlying genetic causes of neurogenic atrophy.
- Stem cell therapy: This involves using muscle-derived stem cells or non-myogenic stem cells to promote tissue regeneration.
- Cytokine therapy: This therapy targets the immune system to reduce inflammation and promote healing.
- Nutrition support: Working with a dietitian to improve nutrition and ensure adequate protein, essential amino acids, creatine, and vitamin D intake can support muscle health. Nutritional supplements may also be recommended.

Lifestyle changes to treat atrophy
Muscle atrophy is the thinning or loss of muscle tissue. It can be caused by disuse of muscles, malnutrition, age, genetics, or neurogenic conditions. Disuse atrophy occurs when muscles are not used regularly or are used but not at an appreciable level of exertion. This can be due to a sedentary lifestyle, a desk job, or medical conditions that prevent physical activity, such as rheumatoid arthritis or osteoarthritis. Neurogenic atrophy, on the other hand, is caused by an injury or disease affecting the nerves connected to the muscles. This type of atrophy is less common but harder to treat as it involves physical damage to the nerves.
Lifestyle changes can play a crucial role in treating muscle atrophy, especially in the case of disuse atrophy. Here are some lifestyle changes that can help:
Increase physical activity:
The leading cause of disuse atrophy is a lack of physical activity. Incorporating regular exercise into your routine can help reverse this type of atrophy. Working out in a swimming pool or doing water exercises can be a good option, as it reduces the muscle workload during the rehabilitation process. Even if you have limited mobility, working with a physical therapist can help you find suitable exercises to improve your condition.
Improve your diet:
Malnutrition is another common cause of muscle atrophy. Improving your diet and ensuring adequate nutrition can help treat and prevent atrophy. Consult a dietitian or your healthcare provider to determine if you need to make any specific dietary changes or take nutritional supplements.
Address underlying medical conditions:
Certain medical conditions can lead to muscle atrophy, either directly or indirectly. For example, conditions like rheumatoid arthritis or osteoarthritis can make physical activity painful or challenging, leading to disuse atrophy. Addressing and managing these underlying conditions is essential for treating the atrophy.
Reduce sedentary behaviour:
If your job or daily routine involves sitting for long periods, try to incorporate more movement into your day. Take breaks to stand up and stretch, or consider a standing desk or walking meetings. Increasing your overall daily activity can help prevent and treat disuse atrophy.
Prevent muscle immobility:
If you are recovering from an illness or injury, try to maintain some level of physical activity to prevent muscle immobility and atrophy. Even small movements or exercises can help. This is especially important if you are bedridden or have limited mobility due to a medical condition.

Physical therapy for muscle atrophy
Muscle atrophy is the wasting or thinning of muscle mass. It can be caused by disuse of muscles or neurogenic conditions. Physiologic or disuse atrophy occurs when muscles are not used enough, while neurogenic atrophy occurs due to nerve problems or diseases.
Physical therapy is a recommended treatment for muscle atrophy. Orthopaedic physical therapists commonly treat both types of muscle atrophy. Physical therapy aims to "manage" the symptoms and slow down the progression of the disease.
For physiologic atrophy, physical therapy will involve an exercise program to help rebuild muscle mass. This may include exercises in a swimming pool to reduce the muscle workload. Physiologic atrophy can often be reversed with exercise and a healthy diet.
For neurogenic atrophy, physical therapy will focus on managing symptoms and may include ultrasound therapy, which uses sound waves to promote muscle healing. This type of atrophy is harder to treat as it involves nerve regeneration, which requires more than just increased exercise.
