What is 'Sarcopenia' that is associated with premature death and many people are at risk?
by on
Sarcopenia, which decreases muscle strength and physical ability with aging, is said to increase the risk of premature death as well as increase the risk of falling and injury. The causes and prevention methods for sarcopenia have been published, although many people have a risk of having symptoms but their awareness is still low.
The muscle-wasting condition 'sarcopenia' is now a recognized disease. But we can all protect ours

Sarcopenia refers to age-related loss of strength or physical ability, like the muscle version of osteoporosis . The “Geriatrics Obesity Practice Guideline 2018 ” announced in December 2018 by the Japan Geriatrics Association in December 2018 calls for attention to “ Sarcopenia obesity ” in which visceral fat is increased but muscle strength is reduced and lean. The
◆ What is the cause of sarcopenia?
As you age, your ability to produce proteins to maintain and grow your muscles diminishes. Also, as you get older, as the signal sent from the brain to the muscles decreases, so does the mass and size of the muscles. In addition, 'lack of exercise,' 'malnutrition,' 'alteration of hormones such as testosterone, ' 'increase in inflammation,' 'presence of other age-related diseases,' etc. may also be the cause.
Who is the cause of sarcopenia?
Studies conducted mainly in Europe and Asia suggest that 10 to 30% of the elderly living in the region suffer from sarcopenia. This figure goes up to 40-50% when limited to over 80 years old, and up to 75% when limited to hospitalized patients.

On the other hand, muscle mass and strength start to fall from the 40s, and if you do not exercise, the speed of strength declines with age. If you do nothing, up to half of your muscle mass will be lost by the age of your 70s, and those with less exercise are said to be easier to replace them with fat. This leads to sarcopenia obesity.
In addition, sarcopenia is especially common in people with cancer, type 2 diabetes, chronic kidney disease, chronic obstructive pulmonary disease, etc. This is because the drugs used to treat the disease affect muscle metabolism. , Because the control of muscle mass goes wrong. Many doctors do not have knowledge about sarcopenia, so there is a fact that it is difficult to treat them considering muscle weakness.
◆ Influence of sarcopenia
Skeletal muscle accounts for 40% of body weight and plays an important role in both exercise and metabolism, such as blood sugar regulation. For this reason, sarcopenia has a negative impact on health in many aspects other than being involved in exercise such as falls and fractures. It has also been reported that weakness and poor recovery after surgery have reduced the quality of life and are associated with premature death.
◆ What is the treatment of sarcopenia?
There is no definitive sarcopenia medication, and twice weekly muscle training is performed, primarily in conjunction with nutrition therapy. Because skeletal muscle has a high ability to regenerate , the results from a 2011 study showed that muscle training increased by 5-10% in 12-week strength training, although muscle strength increased with a range of 30-150%. The experiments conducted at nursing homes for the elderly have also shown increased muscle mass and increased muscle strength.

For elderly patients who may have malnutrition, nutritional therapy such as protein is also important for maintaining muscle strength. You need to eat lean meat, poultry, fish, eggs, nuts / seeds and beans well to ensure that you get protein every day. In addition, vitamin D is also associated with muscle weakness, so it can be well sunlit to produce vitamin D in the body, and if necessary it is also a good idea to take a supplement with the advice of your doctor.
