(HealthDay News) -- Osteoporosis -- caused when the body can't replace bone calcium as fast as it is lost -- is common as people age, particularly among women.

More than 1.5 million Americans each year sustain a bone fracture related to osteoporosis.

Here are common risk factors for osteoporosis, courtesy of the American Academy of Orthopaedic Surgeons:

* Getting older.
* Not doing enough weight-bearing exercises.
* Insufficient estrogen levels after menopause.
* Not getting enough calcium or vitamin D in your diet.
* Certain hormonal imbalances.

(HealthDay News) -- People who are emotionally healthy handle stress well, have a positive self-image, and are able to sustain healthy relationships.

The American Academy of Family Physicians offers these suggestions to help you stay emotionally healthy:

* Establish what you are feeling, and what's causing those feelings.
* Be open with yourself and others about your emotions, instead of keeping the sources of stress and anxiety to yourself.

(HealthDay News) -- A social phobia occurs when a person has unusually high anxiety before a social situation, such as going to a party, giving a speech, or going to a job interview.

It may include some or all of these physical symptoms, says the American Academy of Family Physicians:

* Blushing.
* Sweating.
* Feeling nauseous.
* Trembling or shaking.
* Having trouble talking to or making eye contact with another person.

(HealthDay News) -- Dieting doesn't mean that you have to completely give up desserts. It just means that you should opt for healthier alternatives.

The American Diabetes Association offers these dessert options when you're dieting or trying to watch your sugar and fat intake:

* Try fresh or dried fruits to soothe your sweet tooth.
* Have only a small portion of one of your favorite desserts.
* When ordering at a restaurant, choose a dessert to share with the people accompanying you.
* When baking, reduce the amount of fat and sugar you use in your recipes.
