What causes vertical lines on nails? The reasons are these

The elderly often say that the condition of nails directly reflects the physical health of the human body. So what happens when vertical lines appear on people's nails? This problem has been bothering people. In fact, the appearance of vertical lines on nails is related to many factors, the main reason being physical fatigue.

1. Physical fatigue

If the surface of your nails is not smooth enough and there are obvious vertical lines, it means that you are overworked, lack of sleep, and overusing your brain. You should take more time to rest and absorb more vitamins and protein.

2. Lack of nutrition

Another reason for the appearance of vertical stripes on the nail surface is a lack of vitamin A. You can eat more foods containing vitamin A. Calcium deficiency may also cause vertical lines on the nails.

Calcium deficiency

Vertical lines on the nails may be a sign of a lack of the trace element calcium.

Vitamin A deficiency

The appearance of vertical stripes on the nail surface is a sign of vitamin A deficiency. You can eat more foods containing vitamin A.

3. Other lesions

Vertical lines on the nails may be related to nail damage and lichen planus.

1 nail ridge

The nail plate is thin and brittle, with longitudinal ridges, and the distal end is often ruptured and divided due to malnutrition. It can also be seen in patients with diseases such as lichen planus and alopecia areata.

2 longitudinal grooves

Typically, there is a longitudinal ridge in the center of the nail plate, with the top of the ridge sunken into a shallow groove. There may also be no ridge but obvious grooves. This is often caused by damage to the nail matrix and can also be seen in patients with diseases such as lichen planus. It is a manifestation of allergic reaction.

4. Vertical lines on nails indicate physical illness

What can we see from tiny fingernails? Traditional Chinese medicine believes that fingernails are the external manifestation of qi and blood of internal organs, are directly connected to the internal organs and meridians of the human body, and can fully reflect the physiological and pathological changes of the human body. For example, the half-moon mark located one-fifth of the way below the nail is what we commonly call the crescent moon. It represents the essence of our body, so it is also called the health circle. Normally, there should be 8 to 10 half-moons on the ten fingers. Women with cold body will have fewer half-moons on their nails. The fewer half-moons, the weaker their energy and the colder their physical constitution, which means their immunity is weak and their hands and feet are cold.

1. Darkening of the nails and broken spots under the nails indicate infection-induced myocarditis (serious heart infection), other heart diseases, or bleeding disorders.

2. Some people's nail surfaces are rough, and if you look closely, you can see vertical lines. If this situation appears for a short time and disappears quickly, it is usually due to excessive brain use and overwork; if the vertical lines persist, it may be a chronic disease of the organs in the body. If there are vertical black lines, it means that the liver and kidney functions are relatively weak.

3. There are also horizontal lines. When they first appear, they may start from the bottom of the nail. As the nail grows, they gradually move upward. In this case, the horizontal lines on the nails are a record of the lesions that have occurred. If the horizontal lines are small and numerous, it indicates long-term chronic digestive system diseases, such as gastroenteritis, colitis, stomach disease, etc. If there is a very deep horizontal line, it means that you have had a serious gastrointestinal disease. The deeper it is, the more serious it is; the shallower it is, the more chronic it is. If the horizontal lines are raised, it indicates heart problems, liver problems, and a lack of vitamin A, B, etc.

4. What the crescents tell us The crescents on our ten fingers are closely related to the internal organs. For example, the crescent on the thumb is related to the lungs and spleen. If the crescent on the thumb is pink, it means that the pancreas is dysfunctional and prone to repeated colds and fatigue. If the crescent on the index finger is pink, it indicates poor gastrointestinal function. If the crescent on the middle finger is pink, it means excessive mental tension and prone to dizziness, headaches, unclear thinking, brain swelling, insomnia and nightmares. If the crescent on the ring finger is pink, it means endocrine disorders and prone to gynecological diseases such as irregular menstruation. If the crescent on the little finger is particularly pink, it means that the heart's blood circulation is poor and the internal organs are dysfunctional, certain subjective symptoms will appear. When it is red, it is prone to serious heart disease.

5. Brittle nails may indicate iron deficiency, thyroid problems, impaired kidney function, and blood circulation problems. Brittle, soft, and easily worn nails may indicate a lack of nutrition and may indicate hyperthyroidism.

6. Black nails and/or thin, flat, spoon-shaped nails are signs of vitamin B12 deficiency or anemia. (If your hands come into contact with detergents or allergens, your nails may also turn black or gray.)

7. Dark blue nails indicate lung obstruction, such as asthma or emphysema. Inward-pointing nail tips indicate abnormalities in the heart, liver, or respiratory system.

8. In addition to local fungal infections, green nails can also indicate bacterial infections in the body. Half-white nails with black spots on the fingertips may indicate kidney disease.

9. Isolated green streaks appearing on the nail bed, especially on fair skin, is a sign of skin cancer. Beaded nails (uneven surface) are a sign of rheumatoid arthritis.

10. Nails that extend to the fingertips and curve downward are a sign of lung damage, such as emphysema and asbestosis. Nails that break, crack, and peel easily indicate malnutrition and a lack of hydrochloric acid and protein. Minerals are also extremely deficient at this time.

11. A bulge at the base of the nail with a small white part indicates respiratory disease, such as emphysema or chronic bronchitis. This symptom may be hereditary. Separation of the nail from the nail bed suggests thyroid disease or localized infection.

12. A brass instrument that looks like a flattened nail indicates a tendency to lose some or all of the hair. Reddish-brown acne scars and worn and split fingertips indicate psoriasis, which requires supplementation with VC, folic acid and protein.
