What Thick, Rounded Fingertips Say About Your Health
Health Signs in Hands: Page 6
Known as "clubbing," thickened fingertips that angle out above the last knuckle like miniature clubs can be a sign of heart or lung disease. You may also notice the nail rounding, so your fingers curve downward like the inside of a spoon.
Why? If the circulatory systems of the heart or lungs are impaired, oxygen levels in the blood are likely to drop. Over time, this causes the soft tissues of the fingertip pads to grow, so fingertips (and the ends of toes) appear to bulge outward.
What to do: If your fingers and toes are clubbing, it's likely you've been noticing other symptoms, such a shortness of breath or chronic cough. Clubbing also occurs with aortic valve disease, which can cause fatigue and chest pain. See your doctor for a full heart and lung evaluation. Be sure to tell your doctor how long you've noticed the change in your fingers and toes, as well as how long you've been experiencing other symptoms.
To monitor the oxygen level in your blood, you can get tested by your doctor or use a pulse oximeter, available at most medical supply stores. If you think your heart and lungs are healthy, ask your doctor to run a standard battery of tests. If you're already aware that you have a heart or lung condition, discuss with your doctor whether this may be a sign of worsening symptoms.
