What Causes Unexplained Weight Loss Without Trying?

Unintentional weight loss occurs when you lose 5% or more of body weight within 6-12 months without dietary changes or increased exercise. Common medical causes include hyperthyroidism, which accelerates metabolism, and diabetes, which affects how your body processes nutrients. Digestive disorders like inflammatory bowel disease, celiac disease, and Crohn's disease can impair nutrient absorption. Mental health conditions such as depression and anxiety often reduce appetite significantly. Certain cancers, chronic infections, and medication side effects can also trigger unexplained weight loss. If you've lost more than 10 pounds without trying, consult a healthcare provider for proper evaluation and diagnosis.
