Sarcopenia in older adults is an important and common condition in the elderly, caused by a decrease in muscle mass and muscle strength as age increases.

It affects mobility, quality of life, and increases the risk of falls, which can lead to various complications and even disability.

 

Causes of sarcopenia in older adults

Sarcopenia in older adults is caused by multiple combined factors, including:

1. Causes related to age-related degeneration For example:

• Hormonal changes: decreased growth hormone, testosterone, and estrogen, as well as insulin resistance
• Degeneration of muscle cells
• Reduced muscle synthesis and increased muscle breakdown
• Degeneration of motor neurons, causing muscle atrophy and loss of muscle mass

2. Causes related to diseases or behaviors For example:

• Lack of exercise or physical activity; prolonged bed rest
• Chronic diseases such as diabetes, chronic kidney disease, heart failure, and cancer
• Chronic inflammation
• Malnutrition and deficiency of nutrients such as protein and vitamin D
• Use of certain medications such as steroids

How to recognize sarcopenia in older adults?

• Walking more slowly, unsteady gait, needing support
• Weakness; difficulty rising from a chair; reduced ability to lift arms and legs smoothly
• Easily fatigued and able to perform fewer daily activities
• Reduced ability to lift heavy objects
• Thinning of thigh and arm muscles
• Frequent falls and poor balance
• Weight loss

What are the consequences of sarcopenia in older adults?

• Loss of independence and needing assistance from others for basic activities such as bathing and dressing
• Reduced quality of life
• Increased risk of falls and fractures due to instability while standing and walking
• Higher rates of hospitalization and mortality
• Increased risk of diabetes because reduced muscle mass lowers the use of blood sugar, causing blood glucose levels to rise

How can sarcopenia in older adults be prevented and treated?

Treatment of sarcopenia in older adults requires comprehensive, holistic care in several aspects, as follows:

1. Exercise therapy

• Resistance training, such as lifting dumbbells and using resistance bands, is the most effective way to increase muscle mass and strength.
• Endurance training, such as brisk walking, swimming, and cycling
• Balance and flexibility training, such as yoga, tai chi, and heel-to-toe walking

2. Nutritional therapy

• Adequate protein intake: older adults need 1.0–1.2 grams of protein per kilogram of body weight per day, choosing high-quality protein such as lean meat, eggs, fish, milk, tofu, and soybeans.
• Supplementation with vitamins and minerals that help strengthen muscles, such as vitamin D and certain amino acids
• Ensuring sufficient caloric intake to prevent the body from breaking down muscle for energy

3. Lifestyle modification

• Avoid smoking and alcohol consumption
• Get adequate sleep and rest
• Maintain a healthy body weight
• Optimize control and treatment of existing chronic diseases
