Long upward pointing toenails may be related to long toenails, lichen planus, iron deficiency anemia, psoriasis and so on.
1. Long toenails: For some patients who have not trimmed their toenails for a long time, the toenails may grow upward because of long toenails.
2. Lichen planus: the etiology of lichen planus is still unclear, and it may be related to infectious factors, psycho-neurological factors, endocrine factors and so on. When the disease violates the nail plate, it is easy to cause the nail plate to be thickened and rough, accompanied by longitudinal ridge and transverse groove, and it can also cause nail loss due to progressive atrophy, and some of the patients’ nails may be upward and long.
3. Iron deficiency anemia: iron deficiency anemia is related to insufficient iron intake, excessive iron loss, etc. Common symptoms include pale skin and fatigue. The disease may also cause some patients to have abnormal nails, which may appear as pale, thin or flat nails, or even spoon-shaped nails, which may appear as toenails growing upwards.
4. Psoriasis: The cause of psoriasis is not yet completely clear, and may be related to the interaction of genetic factors and environmental factors. Psoriasis may also cause some patients to have long upward-pointing toenails, and may cause nail pitting, nail separation, and hyperkeratosis under the nails.
It is recommended that people with upward-pointing toenails should consult a doctor for a clear cause and follow the doctor’s instructions for treatment. Pay attention to daily foot care, try to wear loose shoes, and also ensure a balanced intake of nutrients.
