Is their always solution for high hba1c & does it work or it is instantly ?

Glucose control: Blood glucose needs to be kept under-control for A1c to come down. It takes 3-4 months of good control for A1c to come down. There is no "instant" solution. It would help to consult a nutritionist. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex. Get HPV vaccine.
