About the connection between headaches and hormones

In a given year, 18 out of 100 women age 12 and older experience at least one migraine headache, a misfortune that strikes only 6 pecent to 7 percent of men. What’s behind the difference? The answer, in a word, is hormones, but the explanation is far from complete.

The role of hormones

Many factors contribute to headaches for both men and women, including family history and age. Women, however, often notice a relationship between headaches and hormonal changes. Headaches often begin around the time of a girl’s first period and accompany menstruation regularly throughout the reproductive years. Birth control pills and hormone therapy also can trigger headaches. During pregnancy, headaches often become less bothersome. The simple explanation? The hormones estrogen and progesterone — which play key roles in regulating the menstrual cycle and pregnancy — may affect headache-related chemicals in the brain as well. Higher estrogen levels may improve headaches, while lower estrogen levels can make headaches worse. Continue reading About the connection between headaches and hormones

About cytochrome P450 genotyping test

The cytochrome P450 genotyping test (CYP450 test) predicts how your body will process (metabolize) certain antidepressants. The CYP450 test is one of the newer entries in the emerging field of pharmacogenomics, or personalized medicine.

Before the CYP450 test, doctors had little way of knowing how you would respond to a particular antidepressant — whether you would develop troubling side effects, for instance, or whether the medication would even be of benefit. By analyzing how specific genes in your liver break down medications, the CYP450 test may remove some of the guesswork.

The CYP450 test isn’t yet widely available. But as genotyping tests such as CYP450 become more well-known, they may offer better options for the treatment of depression. Continue reading About cytochrome P450 genotyping test

About 5 ways to reduce cholesterol

1. Lose excess pounds

Carrying some extra pounds — even just a few — contributes to high cholesterol. So losing as little as 5 to 10 pounds (2.3 to 4.6 kilograms) can help reduce cholesterol levels.

Start by taking an honest look at your eating habits and daily routine. Consider your challenges to weight loss — and ways to overcome them.

If you eat when you’re bored or frustrated, take a walk instead. If you pick up fast food for lunch every day, pack something healthier from home. If you’re sitting in front of the television, try munching on carrot sticks instead of potato chips as you watch. And, look for ways to incorporate more activity into your daily routine, such as taking the stairs instead of the elevator. Remember that adding physical activity, even in 10-minute intervals several times a day, can help you begin to lose weight. Just be sure that you can keep up the changes you decide to make. Take stock of what you currently eat and your physical activity level, and slowly work changes in. Continue reading About 5 ways to reduce cholesterol

Normal Weight – Healthy Weight

Despite appearances to the contrary, more than half of normal-weight Americans have a high percentage of body fat. And, like their overweight contemporaries, this makes them susceptible to heart disease, diabetes and other metabolic disorders, a new study says.

Men whose body fat is greater than 20 percent and women whose body fat is greater than 30 percent are suffering from “normal weight obesity,” Continue reading Normal Weight – Healthy Weight
