2. Unexplained Weight Loss and Cachexia
While unintended weight loss is a general symptom of various gastrointestinal cancers, it is particularly aggressive and sudden in pancreatic cases. Clinically, losing 5% or more of your total body weight within a single month without any changes to your diet or activity level is a major cause for concern. This rapid decline is often driven by cancer cachexia, a complex metabolic syndrome where the tumor secretes inflammatory proteins that fundamentally alter how the body processes calories and protein. This metabolic hijacking leads to significant muscle wasting and fat loss, which continues even if the patient attempts to maintain a normal caloric intake.
