Unexplained weight loss does not necessarily mean cancer, but it can be a signal that something in your body has changed and deserves a closer look. The American Cancer Society includes an unexplained weight loss or gain of 10 pounds or more among possible signs and symptoms of cancer. Cancer can sometimes cause weight loss by reducing appetite, making you feel full sooner, interfering with nutrient absorption or changing how your body uses energy. But there are many other potential causes, including thyroid conditions, diabetes, digestive disorders, stress and medications. The point isn’t to assume cancer. It’s to dig deeper and find the reason.
If the scale keeps dropping without an explanation—especially if it’s accompanied by fatigue, weakness, appetite changes, bowel changes, difficulty swallowing, persistent pain or unexplained bleeding—talk with a healthcare professional. Your body is giving you information. Pay attention to it.
