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.
Fasting is also important when very accurate cholesterol results are needed, such as in people at high risk for heart disease. Despite studies suggesting that it may not be necessary for everyone, fasting for at least 9 hours before a cholesterol test remains the general recommendation. Do not consume anything except water unless your doctor or the testing laboratory says that it is permitted.
