Are you worried about your Unexplained Weight Loss?

What causes Unexplained Weight Loss?

If you have already ruled out changes to your diet or exercise as the root cause of your weight loss, it is possible that other factors are responsible. Often weight loss can be caused by mental health conditions, it could be a result of an eating disorder, or feeling depressed, stressed, or anxious about something, possibly triggered by a recent bereavement or economic worry. While less common, it is possible that unexplained weight loss happens because of an undiagnosed condition. Digestive problems like coeliac disease, Crohn’s disease, or irritable bowel syndrome (IBS) could be responsible. Other health conditions like heart failure, diabetes, or cancer are possibilities but It is important to remember that many of these conditions are not diagnosed by weight loss alone, those suffering from them will likely have additional symptoms.
