Visual Signs That You Actually Have Health Problems
Pale Skin

If your skin is a good deal lighter than its normal color or tone, then this could be due to reduced blood flow or a reduction on your body's red blood cell production. Skin pigment is often something you can look at to get an indication of whether or not youshould seek nutritional advice or medical advice from a doctor for health concerns.
If you have anemia, your blood does not carry enough oxygen to the rest of your body. The most common cause of anemia is not having enough iron. Your body needs iron to make hemoglobin. Hemoglobin is an iron-rich protein that gives the red color to blood. It carries oxygen from the lungs to the rest of the body.
Anemia is one possible reason for this happening and something you will want to have checked out as soon as you can.Other people might not even notice this change but if you do then you need to do something about it.
Butterfly Rash on Cheeks

The butterfly rash of lupus is typically painless and does not itch, so its definitely a visual health sign you should never take lightly or ignore. More often this visual health sign can be mistake for simple flush cheeks or redness of the cheeks due to a temperature spike from a possible fever, however this can be much more serious.
Along with inflammation in other organs, the butterfly rash of lupus can be precipitated or worsened by exposure to sunlight, a condition called photosensitivity. The photosensitivity can be accompanied by a worsening of inflammation throughout the body, causing a "flare" of the disease.
Rashes are often quick to appear and equally fast to disappear without any other problems.However, the distinctive butterfly shaped rash can be an indicator of lupus erythematosus. There are other possible causes for it as well but you should definitely get a doctor to check it out.
