What is endometriosis?







and Nathan Guimont


Endometriosis is a very common female condition and is defined as the presence of tissue that lines the uterus (or womb) in a location where it is not normally supposed to be. Normally during a woman’s monthly cycle, a mucus tissue (the endometrium) in a women’s uterus builds up and thickens in preparation for fertilization of an egg. When fertilization does not occur, the lining of the uterus breaks down and is discharged at the end of the cycle called menstruation or “period.”

This process is guided by female sex hormones. The endometrium tissue can also grow in other parts of the body, outside of the uterus, and when this occurs it is called endometriosis. The growths are benign but can respond to the hormones as well circulating in your body and guiding menstruation. Continue Reading →

Eyelid twitching is common, usually harmless

But when might it call for a visit to your doctor?  







Doctor, my eyelids have been twitching lately. What’s going on?  


Small, uncontrolled eyelid twitches lasting just a few minutes are very common. The medical term for this is blepharospasm. For the most part, these involuntary eyelid twitches are harmless. Sometimes the twitching can occur, off and on, over several days. Blepharospasm of this type may be associated with fatigue, stress, lack of sleep, excessive caffeine intake, physical exertion, or any combination of these. 

Sometimes, but rarely, the twitching can last weeks or even months. Continue Reading →

These include viral infections, toxic exposures such as alcohol and certain medications, industrial exposures and autoimmune disease.

Good bone health is essential for a good life

Did you know that as we age, 25 percent of patients with a broken bone (especially hip) will need long-term care? Fractures, especially of the hip in those age 60 or older, will also increase your risk of dying within 12 months of the event. Bone strength and bone health are essential for a good, healthy life. When women go through menopause, their estrogen levels decrease, and estrogen is very essential in maintaining healthy bones.
