Coconut water and low-dose aspirin

Created date

Q. Is it safe to drink coconut water?

A. Coconut water is the liquid found inside immature coconuts. Some athletes think it is superior to other sports drinks, and they are partially correct in that coconut water has less sugar, fewer calories, less sodium, and more potassium than many other beverages. But there has been no evidence-based research that supports any genuine health benefits for coconut water. While it is generally safe for most people to drink in moderation, research indicates that it may be harmful to drink it before or after having surgery. The mineral content may also be harmful for some seniors because of possible interactions with other medications. Consult with your doctor before trying coconut water or any other high-mineral beverages. 

Q. Since I started taking low-dose aspirin every day, I seem to bruise easily. Should I stop taking it?

A. Low-dose aspirin is usually prescribed for the prevention of heart attacks or strokes. It works as an anticoagulant, or blood thinner. It may, therefore, make you more susceptible to bruising if you bump into something or have a minor traumatic injury somewhere on your body. Minor bruising doesn’t typically signal a problem, but if you haven’t already, notify your doctor. Also, if you see large bruises or an increase in bruising, especially in areas that have not been subjected to trauma, let your doctor know right away. Aspirin may make you more susceptible to internal bleeding, especially if you are on some other medications.
