Muscle aches and unexplained weight loss may be something simple, or it could be a sign of something more ominous. Diseases causing these symptoms can range from simple nutrition deficiencies to more serious auto-immune conditions. Muscle aches alone are not a major cause of concern. However, when accompanied by unexplained weight loss and other symptoms, it should be evaluated by your doctor.
According to Med Line Plus, muscle aches are frequently caused by tension, overuse or muscle injury from exercise or work. The pain involves specific muscles and begins during or soon after the activity causing the injury. It can also be a sign of conditions affecting your entire body, such as infections like the flu and HIV/AIDS. In addition, other disorders affecting the connective tissues throughout the body such as lupus may cause muscle aches along with weight loss and other symptoms.
Unexplained Weight Loss
Unexplained weight loss should be investigated by your doctor. According to Mayo Clinic, unexplained weight loss is when you lose pounds without dieting. Unexplained weight loss can be a symptom of an underlying medical disorder. If you unexpectedly lose five percent of your body weight or the weight loss continues, there could be a medical reason for it and should be investigated, especially if other symptoms are present.
