I'm 1 1 years old this year, and I've been biting my nails for 6-7mm, while others are1-3 mm. The zinc deficiency was not too serious when I went to the hospital last time. Why?

1. There are many bacteria, which are easy to get sick, such as parasitic diseases, hepatitis and gastroenteritis.

2. It affects the appearance, and it is difficult to recover after the nail is deformed.

3. Mental illness, eating fingernails is a compulsive symptom, which will affect mental health if it is not corrected in time.

You can try the following methods to correct this small problem:

1. Wear rubber gloves on your fingers, which are specially used for counting money. It's a little uncomfortable, but it's ok.

2. Apply warning nail polish to your nails, so that you will have a sense of not biting when you see the warning color, and it will be good to form a habit over time.

3. You can apply cool oil or essential balm on your fingers, which is harmless to your body, but whenever you want to bite your fingers, you will smell the irritating smell, thus stopping the intention of biting.

It is recommended to get into the habit of trimming your nails frequently and keep them clean.
