What Is Weight Loss?

Weight loss is defined as a decrease in body weight. The majority of cases of weight loss result in a decrease in body fat. In severe cases of weight loss however, protein and other various elements of the body may be lost.

What Causes Weight Loss?

Voluntary weight loss is typically seen through a healthy diet and exercise. Involuntary weight loss can be associated by chronic inflammation, addiction to drugs or alcohol, cancer, and chronic diarrheal illnesses.

The decrease of mass associated with weight loss can be caused by a decrease in muscle mass, bodily fluid, or fat. Weight loss that is unintentional or has no explanation is typically an indication of an illness and should addressed by a healthcare professional.

There are several conceivable reasons for unexplained weight loss. These can include:

  • Addison’s Disease
  • Addiction/Substance abuse
  • Cancer
  • Changes in diet
  • Certain medications
  • Chron’s Disease
  • Dementia
  • Dental problems
  • Depression (major depressive disorder)
  • Diabetes
  • Eating disorders
  • Hyperthyroidism

Experience weight loss without an explanation can trigger serious symptoms. The underlying cause for a person’s weight loss will determine the individual symptoms they experience. Common symptoms of unexplained weight loss can include:

  • Loss of appetite
  • Depression

When to See a Doctor for Weight Loss?

Anyone who is losing weight without an explanation, or who isn’t actively trying to lose weight, should consult their healthcare provider.

Older adults who are frail or thin should consult their doctor even when they experience smaller percentages of weight loss in six months or less.
