Difference Between Cachexia and Sarcopenia

Both cachexia and sarcopenia involve muscle loss; these weather besides practise not have specific treatments. Specifically, cachexia is a wasting disorder characterized by involuntary extreme weight loss, muscle wasting, and loss of body fat. In comparison, sarcopenia is a generalized and progressive skeletal muscle disorder which involves accelerated muscle mass and part loss.  Their distinctions are further discussed below.


What is Cachexia

Definition

Cachexia came from the Greek words “kakos” and “hexis” which translates to “bad status”. It is a wasting disorder characterized by involuntary extreme weight loss, and muscle wasting; some may experience loss of body fat. Individuals with cachexia get so fragile and weak that they go vulnerable to various illnesses (Watson, 2018).

Symptoms

The symptoms of cachexia include musculus and fat loss, fatigue, loss of appetite, reduced muscle strength, anemia, high inflammation levels, and swelling. The specific symptoms according to the three master categories are the following (Brennan, 2021):

  • Precachexia

Five percent of body weight is lost due to a disease and is accompanied by appetite loss, metabolism changes, and inflammation.

  • Cachexia

More than 5% of body weight is involuntarily lost in 12 months or less; the other symptoms may include fatigue, loss of musculus forcefulness, ambition loss, fatigue, and inflammation.

  • Refractory Cachexia

This occurs when the patient has cancer and loses weight, musculus part, and response to cancer handling. Around lxxx% of cancer patients experience cachexia in the late stages.

Causes/ Risk factors

Every bit a circuitous syndrome, cachexia’s exact causes may vary; the underlying factors include increased metabolism, increased energy expenditure, reduced nutrition, increased musculus breakdown, and prevention of muscle growth. It oft occurs at the late stages of severe atmospheric condition such equally cancer, chronic obstructive pulmonary disease, chronic renal failure, congestive heart failure, Crohn’south disease, cystic fibrosis, rheumatoid arthritis, and HIV (Nall, 2021).

Treatment

The goal is to improve the quality of life since in that location is no singled-out treatment to reverse cachexia. The therapies employed to address the symptoms include appetite stimulants, nutrition changes, adjusted exercise, and medication to improve mood, lessen nausea, and subtract inflammation (Watson, 2018).


What is Sarcopenia

Definition

Sarcopenia came from the Greek words “sark” which ways “mankind” and “penia” which means “poverty”. Information technology is a generalized and progressive skeletal muscle disorder which involves accelerated muscle mass and function loss. This commonly occurring age-related procedure in older people is frequently associated with falls, frailty, functional turn down, and mortality (Jentoft & Sayer, 2019).

Symptoms

The symptoms of sarcopenia include weakness, loss of stamina, and severe muscle mass loss (aggravated by reduced physical action) which significantly affects balance, gait, and the ability to perform daily tasks (Young, 2017).

Causes

The causes of sarcopenia include the reduction in nerve cells which send signals from the brain to the muscles, lower levels of certain hormones such as growth hormone, insulin-like growth factor, and testosterone, a decrease in the power to transform protein into free energy, and not having enough protein. This condition typically happens faster at effectually age 75 but may speed up at age 65 to 80 (WebMD, 2021).

Treatment

There is currently no medication canonical past the U.Due south. FDA for the treatment of sarcopenia. The use of hormone therapy is beingness investigated to assist increment lean muscle mass. Home remedies include exercise, proper nutrition, and dietary supplements (Pietro, 2017).

Departure between Cachexia and Sarcopenia

Definition

Cachexia is a wasting disorder characterized by involuntary extreme weight loss, muscle wasting, and sometimes loss of body fatty. Individuals with cachexia go so frail and weak that they become vulnerable to various illnesses (Watson, 2018). Equally for sarcopenia, information technology is a generalized and progressive skeletal muscle disorder which involves accelerated muscle mass and function loss. This commonly occurring age-related process in older people is often associated with falls, frailty, functional pass up, and mortality (Jentoft & Sayer, 2019).

Etymology

Cachexia came from the Greek words “kakos” and “hexis” which translates to “bad condition”. In comparison, sarcopenia came from the Greek words “sark” which means “flesh” and “penia” which means “poverty”.

Symptoms

Cachexia’due south symptoms include musculus and fatty loss, fatigue, loss of ambition, reduced musculus strength, anemia, high inflammation levels, and swelling (Brennan, 2021)

Regarding sarcopenia, the symptoms include weakness, loss of stamina, and astringent musculus mass loss (aggravated by reduced physical activity) which significantly affects balance, gait, and the ability to perform daily tasks (Young, 2017).

Causes/ Gamble Factors

Equally a complex syndrome, cachexia’s verbal causes may vary; the underlying factors include increased metabolism, increased energy expenditure, reduced diet, increased muscle breakdown, and prevention of muscle growth. It ofttimes occurs at the belatedly stages of astringent conditions such as cancer, chronic obstructive pulmonary disease, chronic renal failure, congestive heart failure, Crohn’s disease, cystic fibrosis, rheumatoid arthritis, and HIV (Nall, 2021).  In comparison, the causes of sarcopenia include the reduction in nerve cells which transport signals from the encephalon to the muscles, lower levels of certain hormones such every bit growth hormone, insulin-like growth factor, and testosterone, a decrease in the ability to transform protein into energy, and non having enough protein. This condition typically happens faster at around age 75 just may speed up at historic period 65 to fourscore (WebMD, 2021).

Handling

Regarding cachexia, the goal is to improve the quality of life since there is no distinct treatment to reverse it. The therapies employed to address the symptoms include ambition stimulants, diet changes, adapted exercise, and medication to meliorate mood, lessen nausea, and decrease inflammation (Watson, 2018). Every bit for sarcopenia, there is currently no medication approved by the U.South. FDA for its treatment. The use of hormone therapy is being investigated to help increase lean musculus mass. Home remedies include exercise, proper nutrition, and dietary supplements (Pietro, 2017).

Cachexia vs Sarcopenia


Frequently Asked Questions (FAQs):

What is the difference between cachexia and malnutrition?

Cachexia is a wasting disorder characterized by involuntary extreme weight loss and muscle wasting; some patients may also feel loss of torso fatty (Watson 2018). In comparison, the World Health Organization (WHO) defines malnutrition as including undernutrition such as wasting and stunting, having inadequate vitamins or minerals, obesity, overweight, and developing nutrition-related noncommunicable illnesses (2021). Moreover, cachexia is difficult to reverse while malnutrition can be treated with nutritional therapies (Quilty, n.d.)

What is the difference between sarcopenia and muscle atrophy?

Sarcopenia is not always muscle atrophy, and it has been more often than not characterized utilizing muscle strength or mass (Dionne, 2012). In comparison, muscle atrophy is the loss or wasting of muscle tissue (My-MS.org, 2021).

What is the sarcopenia?

It is a generalized and progressive skeletal musculus disorder which involves accelerated muscle mass and role loss. This commonly occurring age-related process in older people is often associated with falls, frailty, functional decline, and mortality (Jentoft & Sayer, 2019).

What are the stages of cachexia?

The 3 stages are (Quilty, n.d.):

Stage 1: Pre-cachexia (weight loss ≤ 5%, anorexia and metabolic change)

Stage two: Cachexia (weight loss ≥ 5% or BMI ≤ 20 kg/m2 or sarcopenia and weight loss > 2%, reduced food intake and systemic inflammation)

Stage 3: Refractory Cachexia (Cannot be reversed; cancer is procatabolic and nonresponsive to handling; low operation score; and expectation of ≤ 3-calendar month survival)

Summary

  • Cachexia is a wasting disorder characterized by involuntary extreme weight loss, muscle wasting, and sometimes loss of body fat (Watson, 2018). Equally for sarcopenia, it is a generalized and progressive skeletal muscle disorder which involves accelerated muscle mass and role loss.
  • As a complex syndrome, cachexia’s verbal causes may vary; the underlying factors include increased metabolism, increased energy expenditure, reduced nutrition, increased muscle breakup, and prevention of musculus growth (Nall, 2021).  In comparison, the causes of sarcopenia include the reduction in nervus cells which ship signals from the brain to the muscles, lower levels of certain hormones such as growth hormone, insulin-like growth factor, and testosterone, a decrease in the ability to transform protein into energy, and non having enough protein.
  • There are no distinct treatments for cachexia and sarcopenia; the therapies employed to address the symptoms of cachexia include appetite stimulants, diet changes, and adapted exercise (Watson, 2018). As for sarcopenia, the utilise of hormone therapy is existence investigated to help increase lean muscle mass. Domicile remedies include practise, proper nutrition, and dietary supplements (Pietro, 2017).
