A piece of sweet corn can detect gastrointestinal disease

Paying attention to disease symptoms in advance is the key to disease prevention. In addition to going to the hospital for a physical check-up, self-health testing is also essential. The health self-test method summarized by many experts helps the public understand their own health status without leaving home.

1. Dancing to test spinal arthritis

Mushtaq Ishaq, an expert at the Royal Orthopaedic Hospital in Birmingham, UK, said that facet osteoarthritis can easily cause back pain.

Dancing movements can reveal symptoms of the disease. Stand up straight, then bend back as far as you can. This action increases the contact between the bones and causes pain.

2. Eating sweet corn can test for gastrointestinal disease

The yellow husk of sweet corn is difficult to digest and absorb, so it can be used to measure how long food takes to pass through the gastrointestinal tract.

It usually takes 24 to 48 hours for food to pass through the gastrointestinal tract. It is abnormal if it takes more than 72 hours. The longer it takes for food to be digested and excreted, the greater the risk of developing diseases such as irritable bowel, gastroenteritis, and colon cancer.

3. Touch your fingers to measure your brain

Coordination test may predict risk of multiple sclerosis or stroke. Dr Helen Stokes-Lampard, an expert at the Royal College of General Practitioners, recommends sitting in front of a friend and asking them to move a finger back and forth, left and right, with the finger at arm's length away from you.

Each time you move, try to touch your friend's fingers, then touch your own nose. If you can't touch your friend's fingers, it may mean that your cerebellum is damaged and you should be aware of brain diseases such as stroke.

4. Use door frames to measure vision

First cover your right eye with your palm, and use your left eye to look at the door frame or window frame from one end of the room. If the vertical and horizontal lines of the door frame or window frame are clear, it means that your eyes are in good condition. If the lines are distorted or deformed, it means that spot degeneration has occurred, which is worthy of attention.
