Youâll have to do some sleuthing to figure out whatâs prompting your perspiration. Night sweats arenât rare: In one study published in Annals of Family Medicine, about a third of primary care patients reported night sweats during the past month.
Cholesterol tests also measure total cholesterol and triglycerides, a type of fat found in the blood. People are typically told to have no food or liquids other than water for nine to 12 hours before the exam. Routine check-ups provide no health benefits, study finds.
Your levels of triglycerides (another type of fat in your blood) may also be affected by a recent meal. But you donât need to decide whether or not to fast; your doctor will tell you if you need to. If they say you should fast, theyâll likely suggest that you avoid eating for 9 to 12 hours before your test. For this reason, cholesterol tests are often scheduled in the morning. That way, you donât have to spend a whole day hungry while waiting to have your test.
