Weight loss
Unintentional weight loss occurs in many diseases and conditions, including some very serious diseases such as cancer, AIDS, and a variety of other diseases.
Poor management of type 1 diabetes mellitus, also known as insulin-dependent diabetes mellitus (IDDM), leads to an excessive amount of glucose and an insufficient amount of insulin in the bloodstream. This triggers the release of triglycerides from adipose (fat) 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. Untreated type 1 diabetes mellitus can produce weight loss.
In addition to weight loss due to a reduction in fat and lean mass, fluid loss can be triggered by illnesses such as diabetes, certain medications, lack of fluid intake or other factors. Fluid loss in addition to reduction in fat and lean mass exacerbates the risk for cachexia.[1]
Infections such as HIV may alter metabolism, leading to weight loss.[2]
Hormonal disruptions, such as an overactive thyroid (hyperthyroidism), may also exhibit as weight loss.[3]
One cutoff value of where unintentional weight loss is of significant concern is where there's a weight loss of more than 5% in the past month, or at least 10% during the last 6 months.[4]
[edit] Causes of unintentional weight loss
Starvation, a state of extreme hunger resulting from lack of essential nutrients over a prolonged period.
Cancer, a very common and sometimes fatal cause of unexplained (idiopathic) weight loss. About one-third of unintentional weight loss cases are secondary to malignancy. Cancers to suspect in patients with unexplained weight loss include gastrointestinal, prostate, hepatobillary (hepatocellular carcinoma, pancreatic cancer), ovarian, hematologic or lung malignancies should be considered in any patient presenting with unexplained weight loss.
AIDS can cause weight loss and should be suspected in high-risk individuals presenting with weight loss.
Gastrointestinal disorders are another common cause of unexplained weight loss - in fact they are the most common non-cancerous cause of idiopathic weight loss. Possible gastrointestinal etiologies of unexplained weight loss are celiac disease, peptic ulcer, inflammatory bowel disease (crohns disease and ulcerative colitis), pancreatitis

The Reason Why Most People Fail At Losing Weight
Why do so many people fail at losing weight? Is it because they are lazy? No. Is it because they are addicted to food? No. Is it because they aren’t good at exercising? No. Failure at weight loss stems from a few main factors:
•People don't truly understand the risks of being overweight. Why do most want to lose weight? Most would say to look better. Looking better certainly is a benefit of losing weight, but this shouldn’t be the sole reason to lose weight. There is a 1000 pound gorilla in the room and it’s often ignored. Being overweight for a long period of time kills thousands of people each year. Thousands of studies have shown and proven without any doubt that losing body fat will improve and lengthen your life. Knowing the dangers of being overweight is a tremendous motivator to not only lose fat, but to keep it off.
•People don't commit to permanent lifestyle changes. So many people think of a "diet" as something temporary. When they are on a "diet" they restrict themselves so much that they are miserable. Sooner or later failure is inevitable because of the unreasonable demands of most "diets." Some of these diets force you to only eat certain foods (e.g., no carbs, special soups etc…) You, like myself, have probably tried them before. The key to losing weight long term is to make gradual lifestyle changes you can stick to forever.
•Most individuals are not provided the truthful facts of losing weight and becoming healthier. With the conflicting information in the media, and all of the different lose weight quick fad diets, it’s understandable why so many people really don’t know the truth about losing fat and keeping it off long term.
•Most people don't understand they are constantly either gaining fat, or losing fat. There is no in-between. Some people justify binging or giving up because they hit a small road-block. This isn’t an all or nothing game. For example, when I was overweight, if I ate an unhealthy lunch, I’d go ahead and eat an unhealthy dinner since I already "messed up" the day. Or I’d say, I’ll start eating healthy on Monday since I’ve already eaten poorly this weekend. Every person at times eats too much. The successful people will not let a road bump completely derail their entire lifestyle change. If you are not implementing positive lifestyle changes and losing weight, you are gaining weight. Again, there is no "in-between."
•Most people don't realize what they consume each day. So many overweight people eat thousands of extra calories and fat without realizing it. It’s tough to know if you are gaining weight or losing weight each day unless you are keeping an eye on what you’re consuming.
