Observing a person’s fingernails can reveal valuable insights about their health status, specifically concerning any abnormalities in shape and color that may signal underlying medical conditions like psoriasis, heart disease, or cancer. However, it is essential to note that issues such as brittle or discolored nails are usually benign and can result from factors like injuries, moisture exposure, nutritional deficiencies, or aging.
When it comes to nail health, Dr. Sara Norris, a naturopathic physician from Los Angeles, emphasizes that for most individuals, nail concerns are often linked to inadequate nutrition or poor digestive health. She commonly addresses issues such as brittle, weak, and peeling nails in her practice, attributing these problems more to dietary inadequacies than systemic diseases.
Therefore, if your nails exhibit such characteristics, there is usually no need for immediate alarm. However, if the condition persists or is accompanied by other symptoms like fatigue, weakness, swelling, heart irregularities, or unexplained weight loss, consulting a healthcare provider is advisable.
Regarding Beau’s lines
Dr. Bhavini Shah, a healthcare provider at Lloyds Pharmacy Online Doctor, explains that Beau’s lines manifest as deep grooves or lines across the nails, indicating a temporary interruption in nail growth likely triggered by severe illnesses or infections. Some individuals have developed Beau’s lines post-recovery from COVID-19, showcasing the impact of significant health stressors like chemotherapy, injuries, or high fevers on nail growth.
Although Beau’s lines may appear and disappear without grave concerns, persistent occurrences or the onset of onychomadesis, a condition where nails stop growing, necessitate medical attention to identify underlying causes.
Concerning Clubbing

The condition of clubbed fingernails, which involves fingertip swelling and nail curvature downward, can gradually progress unnoticed. Dr. Shah suggests that red or purple lines beneath the nails might indicate more than just an injury, potentially signaling an underlying heart disease, warranting a medical assessment.
Clubbing, characterized by nail curvature over the fingertips, is a potential indicator of heart diseases alongside symptoms such as extreme fatigue, leg or arm swelling, and chest, stomach, or jaw discomfort. Notably, some individuals naturally exhibit clubbed nail appearances.
Regarding Spooning

Dr. Shah mentions that inward-curving spoon-shaped nails indicate iron-deficiency anemia, a common condition post-pregnancy characterized by low blood iron levels, leading to symptoms like fatigue, breathlessness, pale skin, and headaches. Iron deficiency may arise from poor diet, celiac disease, or digestive complications.
Identifying the root cause of anemia is crucial; thus, consulting a healthcare provider for a red blood cell count evaluation is recommended. Fortunately, iron-deficiency anemia is easily manageable through iron-rich diets and supplements.
Concerning Pitting or Denting

Dr. Shah mentions that small indentations or pits on nails are common in individuals with skin disorders like psoriasis, eczema, or alopecia areata, each exhibiting distinct external symptoms. While mild cases of nail pitting may not require treatment, severe instances may necessitate dermatological evaluation and potential corticosteroid or vitamin D3 interventions.
Concerning Melanoma
While most individuals associate cancer with abnormal skin spots, melanoma, the severe form of skin cancer, could also manifest on the nails. Hence, consulting a dermatologist upon noticing a dark streak along the nail is advisable. Although not all dark lines indicate cancer, early detection of melanoma facilitates easier treatment.
Regarding Terry’s nails

Dr. Shah highlights Terry’s nails, characterized by a predominantly white nail bed except for a red or pink strip at the tip, as a strong indicator of liver disease, manifesting alongside symptoms like fatigue, yellow skin, or appetite loss. While Terry’s nails might coincide with aging, they could also signify other severe conditions such as heart diseases or diabetes.
Concerning Yellow Nails

Yellow nails may stem from various causes, with fungal infections being a common culprit leading to nail bed retraction, thickening, and crumbling. While treating fungal infections takes time, it’s typically nonpainful. However, in rare scenarios, yellow nails could be symptomatic of underlying conditions like diabetes, psoriasis, thyroid issues, or lung diseases.
