Weight loss, for example, accompanied
by early satiety, bilious vomiting of partially
undigested food, postprandial epigastric pain and
eructation may indicate Superior Mesenteric Artery
Syndrome. Weight loss accompanied by insatiable thirst
and hunger and fatigue may indicate diabetes mellitus, a
chronic disease characterized by an abnormal
accumulation of carbohydrates in the bloodstream due to
insufficient production of insulin, a hormone produced
in the pancreas that, when secreted into the
bloodstream, permits cellular metabolism and utilization
of glucose.

One area involves the science of bioenergetics
including biochemical and physiological energy
production and utilization systems, that is frequently
evidence of diabetes, and ketone bodies, acetone
particles occurring in body fluids and tissues involved
in acidosis, also known as ketosis, somewhat common in
severe diabetes. |

It is not uncommon for people who are
already at a medically healthy weight to intentionally
lose weight. In some cases it is with the goal of
improving athletic performance or to meet weight
classifications in a sport. In other cases, the goal is
to attain a more attractively shaped body. Being
underweight is associated with health risks. Health
problems can include difficulty fighting off infection,
osteoporosis, decreased muscle strength, trouble
regulating body temperature and even increased risk of
death. |

Therapeutic weight loss, in
individuals who are overweight, can decrease the
likelihood of developing diseases such as
diabetes.Overweight and obese individuals face a greater
risk of health conditions such as type diabetes,
heart disease, high blood pressure, stroke,
osteoarthritis and certain types of cancer. For healthy
weight loss, a physician should be consulted to develop
a weight loss plan that is tailored to the individual. |

Weight loss occurs when
an individual is in a state of negative
energy balance. When the human body is
spending more energy in work and heat than
it is gaining from food or other nutritional
supplements, it will catabolise stored
reserves of fat or muscle. |

involve loss of fat, muscle or fluid, weight
loss for the purposes of maintaining health
should aim to lose fat while conserving
muscle and fluid. |

Infections such as
may alter metabolism, leading to weight
loss.Hormonal disruptions, such as an
overactive thyroid hyperthyroidism , may
also exhibit as weight loss. |

In addition to weight
loss due to a reduction in fat and lean
mass, illnesses such as diabetes, certain
medications, lack of fluid intake and other
factors can trigger fluid loss. And fluid
loss in addition to a reduction in fat and
lean mass exacerbates the risk for cachexia. |

A significant loss of
total body weight is a serious, chronic
illness. Substantial, unintentional weight
loss is a symptom of acute or chronic
illness, especially if other evidence is
present. |

Myriad of additional scientific
considerations are applicable to weight
loss, including but not limited to:
physiological and exercise sciences,
nutrition science, behavioral sciences, and
other sciences.

| Poor management
of type 1 diabetes mellitus, also known as
insulin-dependent diabetes mellitus, leads
to an excessive amount of glucose and an
insufficient amount of insulin in the
bloodstream. This triggers the release of
triglycerides from adipose tissue and
catabolism breakdown of amino acids in
muscle tissue. This results in a loss of
both fat and lean mass, leading to a
significant reduction in total body weight.
Note that untreated type diabetes mellitus
will usually not produce weight loss, as
these patients get acutely ill before they
would have had time to lose weight.
