15 Warning Signs from Your Fingernails

Your body communicates when something is wrong. The color and state of your fingernails can let you know when something is going awry inside your body. Sometimes they can be minor vitamin deficiencies and other times more serious conditions. These changes can be subtle, or blatant and it’s worth noting any differences because many diseases are reflected on your fingertips. As always these are warning signs and it’s important not to rely solely on your nails for a health check. Consult with a medical professional who can consider other symptoms and run blood tests.

1. Red nails

If you nails go from a pink shade to a darker red, you might have heart disease. If the redness extends to the sides of your nails and cuticle, this might be a sign of the autoimmune disease Lupus. There are other possible explanations for this reddening, but it’s best to consult with your doctor, who can run tests.

 

2. Unusually white nails

This phenomenon is often called Terry’s nails and has three possible explanations. One is that you have developed a fungal nail infection, often accompanied by reddened or dark fingertips. Another reason could be that your nails have begun to detach from the nail bed and the blood supply is interrupted. Thirdly, this is also a side effect of chemotherapy. Terry’s nails also might indicate that you have a more severe illness like anemia,iron deficiency, diabetes, liver cirrhosis, organ failure or hyperthyroidism.

 

3. Thick or overgrown nails

If you nails are growing thicker and faster than usual, you might be suffering from a serious fungal nail infection. You might also notice that the nails have become discolored. These symptoms are common results of having either psoriasis or arthritis.

 

4. Detached from the nail bed

When nails begin to detach from the nail bed without trauma or pressure, you might have a hormonal imbalance. Similarly if your nails have separated, you might be suffering from hyperthyroidism – a condition where your thyroid gland is releasing too many hormones into your system. For both scenarios a doctor can recommend treatment to reverse these conditions.

6. Blue nails

There are other diseases such as heart disease, anemia and impaired blood flow that are associated with this phenomenon.

10. Brittle nails

11. White stripes

While dark striped nails usually indicate cancerous growth, white stripes are more commonly seen as indicative of a disorder. It usually indicates an imbalanced or innutritious diet, lacking in proteins. This problem can easily be resolved with an increase in proteins rich foods such as fish, quinoa, nuts, seeds and lean meats.

 

12. Curved nails

This condition is sometimes called nail clubbing and involves an unnaturally large nail bed, curving around the tips of the fingers. It is not an overnight condition, and can take several years to form. The cause is often hypoxia, a lack of oxygen. It is not a symptom to ignore as it can be associated with serious diseases like irritable bowel syndrome, liver disease, lung problems, AIDS and cardiovascular concerns.
