Fasting is usually required for blood tests to detect hair loss.
Fasting before blood tests helps obtain more accurate results. This is because food affects certain components of the blood, such as blood sugar and blood lipids, thus influencing the accuracy of the test results. To ensure accurate results, doctors usually require patients to fast before blood tests.
For patients with hair loss, blood tests can provide information about nutritional status, hormone levels, thyroid function, and other factors that can affect hair growth. Before undergoing a blood test, patients need to follow their doctor's instructions, which usually includes fasting. Fasting time is generally 8-12 hours to ensure that the components of the blood are not affected by recent eating.
Before your blood test, make sure to prepare according to your doctor's instructions. If your doctor requires fasting, do not eat anything for 8-12 hours before the test, only drink water. Avoid strenuous exercise and alcohol before the test, as these may affect the results. After the test, you can resume your normal diet, while adjusting your lifestyle and diet according to your doctor's advice to promote healthy hair growth.
