Unexplained Weight Lossl

Dramatic, unexplained weight loss could be an early sign of Type 2 diabetes—glucose builds up in your blood instead of being transported to your cells. "This weight loss can occur relatively quickly — over a few weeks to a couple of months," says registered nurse Sue Cotey, RN, CDCES. "When the glucose doesn't arrive in your cells, your body thinks it's starving and finds a way to compensate. It creates energy by burning fat and muscle at a rapid pace. This causes unexplained weight loss."

Waxy bump clusters that suddenly appear on skin could be a sign of high cholesterol in the blood. According to the Cleveland Clinic, "When considering cholesterol numbers, it's important to remember that you really have the ability to make those numbers go in your favor. What you choose to eat, how much you are able to move and how you deal with life's ups and downs are things that you can influence." Either way, make sure to meet with a medical professional to get help and guidance.

Feeling the need to urinate more often (and excessive foam in urine) could be a sign of kidney disease, according to the National Kidney Foundation. "There are a number of physical signs of kidney disease, but sometimes people attribute them to other conditions," says Dr. Joseph Vassalotti, Chief Medical Officer at the National Kidney Foundation. "Also, those with kidney disease tend not to experience symptoms until the very late stages, when the kidneys are failing or when there are large amounts of protein in the urine. This is one of the reasons why only 10% of people with chronic kidney disease know that they have it."

"It is far better to stop liver disease before it gets too serious."
