There are special tests that you can do in order to diagnose a serious illness, even before the first symptoms appear.
These are a series of simple tests you can do to estimate the risk of developing some diseases and figure out whether you need to see a specialist.
1. Heart And Lung Disease
Make your fingers in the shape of an upside-down letter J and put your nails against one another. Do you see a tiny diamond between them? Great, this means that your heart and vessels are perfectly healthy.
If there is no space between your fingernails, it may be a sign of nail clubbing. The fact that fingers become thicker means that the blood doesn’t have enough oxygen. Oxygen deficiency can be caused by multiple reasons. For example, cardiovascular diseases, lung problems, and gastrointestinal issues.
2. Stroke And Dementia
You need a timer for this test. Lift your leg up so that the hip is parallel to the floor and start the timer. If you can stand like this for 20 or more minutes, it means you have minimal risk of having a stroke or developing dementia. And vice versa: if you have trouble maintaining balance on one leg, it might indicate problems with vessels of the brain.
When standing in front of a mirror, pull your lower eyelid down. If the color is pink, everything is okay. However, if you have anemia, the color may be a pale pink or even yellowish. Anemia is caused by a lack of hemoglobin and indicates that the muscles and tissues in the body aren’t receiving enough oxygen and can’t work at 100%. If you notice that you are pale, you get tired quickly or breathe heavily, you should get a doctor to examine you.
4. Carpal Tunnel Syndrome
This test can detect a professional problem of office workers, artists, and bikers — carpal tunnel syndrome.
Lift your hands up so that your forearms are parallel to your face. Try to reach the base of the palm with the tips of your fingers. If you can do this for 1-2 minutes, you are fine. But if you have tingling, numbness, or pain in your wrists or fingers, this can be a sign of tunnel syndrome.
Carpal tunnel syndrome appears when the neighboring tissues press on the median nerve. The pain and numbness will only get worse without the proper treatment.
In order to do this test, you need help. Ask a partner to take a pencil with an eraser. Get them to touch your foot and toes with the sharp end of the pencil and with the eraser, in turns. Can you tell which side of the pencil touched you without looking?
If you don’t fully feel the touch, it means that the nerve endings on your feet don’t function properly. Low sensitivity can be an indicator of diabetes.
