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.
The most accurate test to determine your cholesterol requires fasting for 12 to 14 hours before a blood sample is taken. Fasting is necessary because triglyceride levels--one component of your total cholesterol count--can change dramatically after a meal. Some health-care professionals say you can drink black coffee and water during a fasting period. Others say water only during fasting. Ask your health-care professional.
