New research about how we store fat will help you keep your hands off the
When we think about losing weight, most of us focus on two things: the food
we eat and the stomach where it ends up. The first part makes sense. But the
second part is misguided. It's not a big stomach that gives us our beer belly,
but a layer of fat called the omentum, which hangs in front of our intestines
and stomach. And it's how food interacts with...
It’s normal. Seventy percent of boys get it during puberty. It’s caused by natural changes in estrogen (a "female hormone" that men also have) and testosterone. Newborn babies sometimes have short-term gynecomastia, too. That’s because some of their mothers’ estrogen stays in their blood for a while after birth.
Middle-aged and older men can also have the condition. It could be due to aging (which also shifts hormone levels) or because of certain medicines, including some:
Herbal products that contain tea tree oil or lavender oil can also increase breast size. That’s because they have natural estrogen that can upset your body’s normal hormone levels.
Sometimes it happens because of another health problem, like an overactive thyroid, kidney disease, or a tumor on one of the glands that controls your hormones.
Men with gynecomastia have a firm, rubbery mass underneath the nipple area. It’s usually less than an inch and a half across and may be tender. Sometimes there aren’t other symptoms. You may notice some fluid discharge.
It can affect one breast or both.
The cause of gynecomastia isn’t always clear. So it’s a good idea to check in with your regular doctor or an endocrinologist, a doctor who specializes in hormone imbalances. During your appointment he may ask you:
How old were you when you noticed a change in your breast size?
Does the condition run in your family?
Have you noticed a difference in your nipple size?
Have you had any discharge or pain?
How's your overall health?
Do you drink alcohol, use drugs, or have you had infertility problems?
