From
finger length to grip strength, our hands can indicate risk factors for
a number of surprising conditions.

Shaky hands reveal: Parkinson's disease
Trembling hands could be the result of something as simple as too much
caffeine or a side effect of certain medications like asthma drugs and
antidepressants. But it's a good idea to see your doctor if the issue
recurs. A tremor in just one hand can be a first symptom of Parkinson's
disease, or it can indicate essential tremor, a disorder that causes
uncontrollable shaking and is treatable with therapy or medication. |

Nail color reveals: Kidney disease
When Indian researchers studied 100 patients with chronic kidney
disease, they found that 36 percent had half-and-half nails, when the
bottom of a nail is white and the top is brown. The nail condition may
be caused by an increased concentration of certain hormones and chronic
anemia, both traits of chronic kidney disease. See your doctor right
away if you notice half-and-half nails or a dark, vertical stripe
beneath the nail bed. This can be hidden melanoma, a skin cancer. |

Grip strength reveals: Heart health
A weak grip predicts a higher risk of heart attack or stroke and lower
chances of survival, according to a new Lancet study of nearly 140,000
adults in 17 countries. Grip strength was a better predictor of death
than was blood pressure. Researchers say grip strength is a marker of
overall muscle strength and fitness, and they recommend whole-body
strength training and aerobic exercise to reduce heart disease risk. |

Sweaty palms reveal: Hyperhidrosis
Overly clammy hands may be a symptom of menopause or thyroid conditions,
as well as hyperhidrosis, in which overactive sweat glands cause far
more perspiration than necessary. Most people with the condition sweat
from only one or two parts of the body, such as the armpits, palms, or
feet. A doctor may prescribe a strong antiperspirant to decrease sweat
production. |
