Methods for lowering hemoglobin A1C levels include exercise, a low-fat diet, eating at regular times and following a prescribed treatment plan, explains Everyday Health. The speed at which A1C levels come down depends on the person. It may take some time to see a difference because A1C levels reflect blood sugar levels from the past two to three months.
A recommended diet for those looking to reduce their A1C levels includes non-starchy vegetables, whole grains, healthy fats, lean proteins and dairy, reports Everyday Health. High-fiber foods, such as fruits, vegetables and grains, are linked to improved blood sugar levels over time. The recommended amount of exercise involves 30 minutes of activity, five days a week. Individuals can do any activity they enjoy that gets them moving, such as biking or walking. Treatment plans may include medication and regularly checking blood sugar.
The A1C test measures how much glucose is attached to the hemoglobin proteins in blood, explains Everyday Health. Unlike blood glucose monitoring, a trained healthcare worker must perform this test at a medical office. Normal levels are below 5.7 percent. Between 5.7 percent and 6.4 percent is considered prediabetes, and 6.5 percent and above indicates diabetes. The test doesn't require the person to fast and may be done at any time of day.
