What is Decreased Muscle Mass? (Sarcopenia & Muscle Atrophy Explained)
Decreased muscle mass, also known as muscle loss, is a condition where the body loses skeletal muscle tissue. It's a common problem, especially with age, significantly impacting health and quality of life.
Causes of Decreased Muscle Mass: Several factors contribute to decreased muscle mass. Sarcopenia, the age-related loss of muscle mass and strength, is a primary cause. As we age, the body produces less protein, hindering muscle building and maintenance. Other factors include:
- Lack of physical activity: A sedentary lifestyle leads to muscle atrophy.
- Poor nutrition: Insufficient protein, calories, or essential nutrients hinder muscle growth and repair.
- Underlying medical conditions: Illnesses such as cancer, diabetes, and heart disease can contribute to muscle loss.
- Medications: Some medications, like corticosteroids, can cause muscle wasting.
- Genetics: Genetic predisposition plays a role in muscle mass loss.
Identifying Decreased Muscle Mass: Symptoms of decreased muscle mass include:
- Weakness: Difficulty lifting objects previously manageable.
- Fatigue: Persistent tiredness despite sufficient sleep.
- Difficulty with daily tasks: Challenges with activities like climbing stairs or carrying groceries.
- Changes in body composition: Noticeable decrease in muscle size or increase in body fat.
Combating Decreased Muscle Mass: It's possible to combat decreased muscle mass at any age.
- Resistance training: Weightlifting, bodyweight exercises, or resistance bands are crucial. Aim for at least two sessions per week, targeting all major muscle groups.
- Nutrition: A protein-rich diet is essential for muscle growth and repair. Good sources include lean meats, fish, eggs, beans, and lentils. Include fruits and vegetables for overall health.
- Lifestyle factors: Sufficient sleep, stress management, and addressing underlying health concerns are important for maintaining muscle mass.
In short: Decreased muscle mass is a serious condition affecting health and well-being. A proactive approach—including regular resistance training, a balanced diet, and addressing underlying health conditions—can help maintain or increase muscle mass at any age.
