7 Surprising Health Conditions Your Nails Can Reveal
We often overlook our nails, focusing more on skincare and haircare, but these small parts of our body can actually be windows into our overall health. Changes in the color, texture, or shape of your nails can signal underlying health issues — some of which may require medical attention.
Here are 7 surprising health conditions your nails can reveal, helping you stay informed and proactive about your well-being.
1. Anemia
If your nails appear pale or white, it could be a sign of anemia — a condition where your body lacks enough healthy red blood cells. Anemia can cause fatigue, weakness, and shortness of breath, so noticing pale nails might be an early clue to get checked.
2. Diabetes
Yellowing nails or thickened nails might point to uncontrolled diabetes. Elevated blood sugar can lead to fungal infections or poor circulation, which affects nail health. If you spot these changes alongside other symptoms, it’s wise to talk to your healthcare provider.
3. Liver Disease
White nails with darker rims — often called “Terry’s nails” — may indicate liver problems such as cirrhosis or hepatitis. This happens due to changes in blood flow and protein levels, and it’s important to seek medical advice if you notice this pattern.
4. Heart Disease
Clubbing — when nails curve downward and fingertips swell — can be a sign of heart or lung diseases. This condition occurs due to low oxygen levels in the blood and should be evaluated promptly.
5. Thyroid Disorders
Brittle, dry, or slow-growing nails can be linked to hypothyroidism (underactive thyroid). Conversely, nails that separate from the nail bed might be seen in hyperthyroidism (overactive thyroid). Nail changes, combined with other symptoms like fatigue or weight changes, warrant a thyroid check.
