Are you putting off seeing your doctor, even though you’ve got a few nagging issues? Well, here are the symptoms you should never ignore – because they might be a sign of something serious:

  • Unexpected weight loss. It may seem awesome, but could actually indicate a problem. If you’re dropping pounds without trying, it could indicate a thyroid problem - or, worse yet, cancer. And the sooner you get checked out, the better off you’ll be.

  • Persistent coughing. Pulmonary expert Dr. Norman Edelman says that anyone with a cough that never goes completely away may have chronic obstructive pulmonary disorder – or even lung cancer. And both diseases can get worse rapidly, so you need to get checked out as soon as possible.

  • What if you find yourself constantly running to the bathroom? Frequent urination is one of the first signs of diabetes, because excess blood sugar makes your kidneys work overtime.

  • Balance problems. Dr. Leslie Kernisan specializes in geriatric medicine. And she says that tripping and stumbling can be caused by neurological issues, vision problems, and even prescription meds.

  • Discomfort when you exercise. This is especially important for women. According to the American Heart Association, low levels of pain in your chest, arms, or neck can be a sign of coronary artery disease. And the pain comes from restricted blood flow. And in women, it’s often the only warning sign before a heart attack.
