Very high triglycerides can be caused by poor diet and not enough exercise. You may also have inherited very high triglycerides from a parent. Your doctor will tell you how to manage your triglycerides. If your weight is higher than what is considered healthy, losing even 5 pounds may help lower your triglycerides.
WORD likes it un-hyphenated but I don't. Long-term should be hyphenated but longtime should not be hyphenated, at least until a few more decades pass and the grammatical rules for the use of hyphens either relax or fade away. Here is part of an erudite commentary on this subject:
Both forms exist; the difference between them (ie the use of the hyphen) is very important and applies to many other grammatical forms. When talking about the âlong termâ, we are talking about the noun âtermâ which is described by the adjective âlongâ. However, where the entire phrase is used to describe something else, we must use the hyphen to show this. This is called a premodifying compound adjective. We are planning for the long term.
