I make this News contribution today hoping I dont unduly alarm anyone, but because it may be worth thinking about or printing and taking to a doctors appointment. I know this can be an issue with PD, especially late-stage. In the body of the article I inserted [ ] the definition of this condition
Excessive Weight Loss Can Be A Bad Thing
21 Jan 2009
Doctors are not doing enough to pick up on problems with excessive weight loss, says a Saint Louis University physician who helped draft recent guidelines to diagnose the condition called "cachexia" (kuh-kex-ee-uh).
"In sick people, weight loss is an important indicator of disease and potentially impending death," said John Morley, M.D., an endocrinologist and director of the division of geriatric medicine at Saint Louis University School of Medicine.
"Cachexia is an extraordinary problem for people who are having other health problems, yet this is something that many physicians don't pay attention to."
A group of physicians and scientists agreed on a definition of cachexia, which was published in the December edition of the medical journal, Clinical Nutrition. [Cachexia: Physical wasting with loss of weight and muscle mass caused by disease. Patients with advanced cancer, AIDS, and some other major chronic progressive diseases may appear cachectic. Cachexia is a wasting syndrome that causes weakness and a loss of weight, fat, and muscle. Anorexia (lack of apppetite) and cachexia often occur together. Cachexia can occur in people who are eating enough, but who cannot absorb the nutrients. Cachexia is not the same as starvation. A healthy person's body can adjust to starvation by slowing down its use of nutrients, but in cachectic patients, the body does not make this adjustment. (Source: MedicineNet.com
"The definition is important because it gives physicians the guidelines to make a diagnosis and treat the condition," Morley said. "A definition of cachexia also makes it easier for scientists to conduct research and potentially develop new therapies for the problem."
About half of hospitalized patients and between 10 and 15 percent of sick patients who see a doctor have cachexia. The condition accompanies diseases such as cancer, congestive heart failure, HIV, diabetes, kidney failure and COPD (chronic obstructive pulmonary disease).
Adults with cachexia lose weight and children don't grow. Muscle mass melts away, and those with cachexia also may lose fat.
Those who traditionally have had difficulty taking off weight and suddenly find the pounds melting off should beware, Morley said. They may be ill and could get even sicker as they become weaker and weaker.
"Cachexia should be seen as a wasting disease that requires specialized treatment from a physician who is familiar with the problem," Morley said.
The researchers clarified the definition of cachexia by noting it is always linked to an underlying disease. They differentiated it from starvation; loss of muscle mass that comes with aging; depression; thyroid problems; and the body's difficulty in absorbing nutrients. Rather, cachexia is a complicated metabolic syndrome that is often associated with anorexia, inflammation, insulin resistance and increased muscle protein breakdown.
Established in 1836, Saint Louis University School of Medicine has the distinction of awarding the first M.D. degree west of the Mississippi River. Saint Louis University School of Medicine is a pioneer in geriatric medicine, organ transplantation, chronic disease prevention, cardiovascular disease, neurosciences and vaccine research, among others. The School of Medicine trains physicians and biomedical scientists, conducts medical research, and provides health services on a local, national and international level.
