What your feet nails (and hands) reveal in silence on your health
We cut them, we varnit them, sometimes we forget them. And yet, your nails, especially those of your feet, are real barometers of your general state of health.
We cut them, we varnit them, sometimes we forget them. And yet, your nails, especially those of your feet, are real barometers of your general state of health. Much more than an aesthetic detail, their appearance can point out internal imbalances, deficiencies or even silent diseases. Learning to decode these little signs is like reading a secret card that your body tries to strive for yourself. Here is all that your nails could tell you.
Color: discreet but revealing language
Each shade hides a meaning:
- Yellow: often linked to fungal infection, sometimes to chronic respiratory concerns.
- White with pink band (Terry nails): can report a liver, heart or diabetes disease.
- Pale: suspicion of anemia or bad traffic.
- Blue or purple: Lack of oxygen in the blood, pulmonary or heart problem.
- Gray: side effects of drugs.
- Brown: potential thyroid alert.
Your varnish can hide these colors, but your body never lies.

Form and structure: when the nail transforms
Some deformations must alert:
- Tilting nails: often linked to iron deficiency or cardiovascular concern.
- Drum wand -like bangs: sometimes signal pulmonary or digestive diseases.
- Nail that takes off: this can evoke hyperthyroidism or psoriasis.
- Half-And-Half nails: half a white, the other dark, often associated with renal failure or chronic pathologies such as cirrhosis.

Texture and streaks: a surface that speaks
The tactile aspect of the nails should not be overlooked:
- Brittle, who duplicate: lack of biotin, vitamins A or C, or hypothyroidism.
- Vertical streaks: normal with age, but if marked early, watch out for vitamin B12 or magnesium.
- Horizontal streaks (beautiful lines): often linked to high fever or serious infection.
- Picking (small holes): typical of psoriasis or certain inflammatory joint diseases.
Dark lines and disturbing anomalies
Some brands deserve a consultation without delay:
- Vertical black streaks: an under-uunguéal melanoma can be involved-a dermatological emergency.
- White lines (Mees lines): often linked to heavy metal poisoning or protein deficiency.
- Skin swollen around the nail: infection or sign of autoimmune diseases like lupus.

Yellow nail syndrome: When the nail speaks for the lungs
Thick and yellow nails, slow to push and accompanied by swelling of the legs and respiratory disorders? This could be yellow nail syndrome, a rare but revealing disorder of lymphedema and pulmonary pathologies. It’s a combination to take very seriously.
Preserve the health of your nails: good reflexes
- Food: iron, zinc, biotin, vitamins A, B12 and C are essential.
- Hygiene: Keep your clean nails, cut them straight, avoid gnawing them.
- Protection: limits exposure to chemical solvents, uses household gloves.
- Varnish break: let them breathe regularly.
Bonus: Each week, takes 10 minutes to make a foot bath with olive oil and lemon to restore strength and shine to your nails naturally. Simple, efficient and economical.

Your nails are small discreet indicators, often neglected, but which can announce great upheavals. A change in color, shape or texture should never be taken lightly. If you observe something strange, don't be satisfied with a varnish to camouflage it: listen to what your body is looking to tell you, and consult if necessary.
