Glaucoma is the leading cause of irreversible blindness in the world. Glaucoma is often associated with elevated intraocular pressure, in which damage to the eye (optic) nerve can lead to loss of vision and even blindness.
A cataract is a clouding of the lens in the eye over time as people age. Cataracts often develop slowly and can affect one or both eyes. The only treatment is to have the effected lens replaced through surgery.
Refractive eye surgery is the term used to describe surgical procedures that correct common vision problems such as nearsightedness, farsightedness, astigmatism and presbyopia. Surgery can eliminate the need for prescription eyeglasses and/or contact lenses.
Should I change my diet when trying to conceive?
When you're trying to get pregnant your diet should basically be the same as if you are pregnant. However, it is important to take a vitamin that has at least 1 milligram of folic acid.
You should be avoiding the large fish that contain the mercury as well as the unpasteurized cheeses. It's important that your diet is balanced: fruit, vegetables, carbohydrates and protein, and you also avoid caffeine and alcohol.
If you are trying to get pregnant and have questions about what you should and should not be eating, and what supplements you should be taking, please contact your healthcare provider.
What are the guidelines for exercise in the third trimester?
Basic trimester guidelines for exercise in pregnancy are really important to follow. In the first trimester, if you previously were not active, you definitely want to consult your doctor. If you were active, you can keep up the program that you were previously engaged in. In the third trimester, it is important to consult with your doctor on your exercise intensity, ensuring that you're staying within your rate of perceived exertion.
What is pre-diabetes?
Pre-diabetes is a precursor to diabetes. It means you have risk factors that are trending toward diabetes levels and you should be taking steps to work on your health. Usually, it involves your blood sugar being slightly higher than normal, but not quite at the level where you would be diagnosed with diabetes. If your doctor has told you that you have pre-diabetes, he/she can help you understand what you can do to work on this.
