When to know if the skin indicates health problems

The largest organ in the body is the skin. Sometimes referred to as the window of one's welfare because it can bring clues about the health of other organs. Skin changes, ranging from color changes to new growth, are sometimes the first sign of a more serious health problem, the dermatologist says.

"I always find out that the clues are changing, why they are there, what are the other symptoms, that's a clue that will help me discover what's going on inside, both mind and body," says Dr. Doris Day, Dermatologist at Lenox Hill Hospital, New York City

Here are some signs of skin changes that indicate health problems, as quoted from Foxnews:

1. Rash and stripes on the skin
In general, a skin rash that does not respond to treatment accompanied by other symptoms such as fever, muscle pain, joint pain can be a sign of an internal problem or infection. Rashes can also occur due to allergies or signal reactions to drugs, according to the American Academy of Dermatology (AAD).

"Velvety rash on the back of the neck or around the arm, usually in a slightly darker color than normal skin color, is a sign that patients may have an increased risk of developing type 2 diabetes. When I look at it, I ask the patient to check blood sugar And keep their food, "Doris Day said.

In addition, a velvety rash on the skin called acanthosis nigricans can be a warning sign of cancer in internal organs, such as stomach or liver, according to the Mayo Clinic. Meanwhile, a purple rash on the lower leg that does not respond to topical treatment may be a sign of hepatitis C infection, Doris said.

2. Changes skin color to dark red or other colors
In diabetics, skin becomes dark red (bronzing) can be a sign of problems with iron metabolism, Doris said. While the yellow color on the skin, it may be a sign of liver failure and can occur along with yellowing of the eyes.
Darkening of the skin is mostly seen in scars and skin folds, as well as in joints, such as elbows and knees can be a sign of hormonal diseases, such as Addison's disease that affects the adrenal gland.

3. New skin growth
People who see new growth in the skin should consult a doctor, as it could be skin cancer. Sometimes it is also a sign of internal disease or genetic syndrome, according to AAD.

4. Nail color change
The change of color or the shape of the nail is often a sign of a deficiency problem or organ system. For example, a nail change that looks like a yeast infection can actually be a result of psoriasis on the nail, although the condition usually affects the skin. People who also have joint pain can have a form of arthritis called psoriatic arthritis. In addition, liver and kidney problems can sometimes cause nail discoloration.

5. The skin hardens and dries
High blood pressure and kidney problems sometimes cause skin thickening of the shin. In addition, very dry skin, itchy skin, can be a sign of hormonal problems, such as underactive thyroid.

"If you are over 30 or 40 years old, and you have never had eczema since children, suddenly your skin is dry and it seems to be eczema could be a sign of hormonal problems like low thyroid function," said Doris.

People with an autoimmune disease called systemic sclerosis can experience swelling and hardening of the skin. In more severe cases, this can cause internal hardening of organs, such as the lungs or heart, according to AAD.
