Facts about bruising, gambling, and color blindness

Q. Do women get color blindness?

Color blindness affects about 10 percent of men, but only 1 percent of women.

Color blindness is the common term used to describe color vision deficiency. The term is misleading, because total color blindness that turns the world into shades of gray is rare.

The most common type of color blindness makes it difficult for people to discriminate between red and green. The next most common form of the deficiency affects the perception of blues and yellows. Those with blue-yellow blindness almost always have red-green blindness, too.

Most people with color blindness inherited it. There is no treatment to correct inherited color blindness. However, there are specially tinted eyeglasses that can help people with deficiencies to discriminate between colors.

Q. I'm taking a variety of medications and was wondering if any of them can contribute to bruising.

Blood-thinning medications can contribute to bruising. So you might bruise more easily if you take Plavix or Coumadin. Aspirin will have a similar effect. The thinners allow more blood to pool under your skin. So, if you’re taking one of these drugs, what seems like a harmless bump against a coffee table could lead to a nasty bruise.

Some dietary supplements can thin your blood, too. Be careful if you are consuming more than normal amounts of fish oil, ginkgo, ginger and/or garlic.

A tendency to bruise easily is common when you age. It’s especially common among women.

A bruise – also known as a contusion – occurs when the tiny blood vessels under your skin break after being struck. When you bruise, the blood leaks under the skin and leaves a black-and-blue mark. The harder the impact, the bigger the bruise. As the blood is reabsorbed by your body, the bruise goes away.
