Illnesses were high fever is a symptom

If the person has suffered a serious illness such as pneumonia or scarlet fever, they could get horizontal fingernail lines.

In this case, they may appear because the person’s body has given priority to fighting the illness instead of nail growth.

No treatment is necessary, because the white lines will disappear upon recovery from the illness. 

Since nails grow approximately 1 millimeter per week, it’s possible to calculate the date in which traumatic stress occurred in one’s body.


If diabetes runs in your family and you suffer from other characteristic symptoms of this disease, the lines in your nails could be the consequence of untreated diabetes.

The first step to take should be to visit your doctor in order to perform the corresponding tests and obtain a diagnosis.



This skin disorder causes scaling and inflammation and affects different parts of the body. It may also affect the fingernails, causing horizontal lines.

Those who suffer from psoriasis may live with a great deal of discomfort, as the pain and itching can be overwhelming.

Although psoriasis has no cure, many people have noticed that eating a balanced and healthy diet produces favorable changes in their condition.

We recommend including fresh, natural foods in your diet, and reducing your intake of foods with refined sugar and harmful fats.

Circulation disorders

If you suffer from poor circulation and have other symptoms such as varicose veins and leg pressure or heaviness, it’s possible that this may be the cause of the lines in your nails.

For better circulation, we must exercise and eat a fresh, complete diet. 

  • We recommend increasing your intake of red foods (tomato, red fruits, cayenne pepper, etc.).
  • You can also take baths at alternating temperatures (cold-hot) and undergo massages with essential oils (rosemary, cypress, witch hazel).

Zinc deficiency

Zinc is a mineral essential to many of the body’s functions. It’s also needed for strong, healthy nails.

Zinc deficiency can cause the appearance of marks or horizontal lines. These serve as a warning sign and a reminder to increase zinc intake.

Zinc can be taken in supplement form, or it can be consumed in the following foods:

  • Powdered cocoa
  • Dry watermelon seeds
  • Meat
  • Oysters
  • Peanuts
  • Sesame
  • Pumpkin (and its seeds)
  • Butter

Vertical fingernail lines

The causes of vertical lines are different from the causes of horizontal lines.


A woman aging.

The most common explanation for the appearance of vertical fingernail lines is the unavoidable aging process.

Nonetheless, by consuming a diet rich in antioxidants, we can delay the deterioration caused by free radicals, both internally and externally.

These are some foods that contain the highest levels of antioxidants:

  • Cocoa
  • Garlic and onions
  • Avocado
  • Grapes
  • Tomatoes
  • Lemons
  • Broccoli
  • Turmeric
  • Green tea
  • Nuts
  • Apples
  • Pepper

Vitamin B deficiency

In some cases, the appearance of fingernail lines can be related to a vitamin B deficiency.

This can be due to poor assimilation of this nutrient or by adhering to a strict vegetarian diet. 

The following foods are good sources of Vitamin B12:

  • Eggs
  • Meat
  • Shellfish
  • Dairy products
  • Spirulina
  • Brewer’s yeast

Magnesium deficiency

Lack of magnesium can also cause fingernail lines. Unfortunately, food is increasingly lacking in this mineral because of poor soil, which is increasingly lacking in nutrients.

Taking magnesium supplements is highly recommended. The most common supplements are chloride (may be excellent for fighting constipation) and citrate (more suitable for those who suffer from gastric acidity).
