I was diagnosed of prediabetics recently. My Fbs after 12hours of fasting was 113mg/dl in April 2020, 109mg/dl in May 2020 and currently (106 mg/dl) for June 2020. I do an hour exercise daily with carbs reduction and eat alot vegetables, carrots and cucumber. However the symptoms are all over me. I have fatigue, thrist, joint pains, anxiety and frequent urination. In view of these obvious sign/symptoms should I start medication immediately because I feel exercise and less carb is not doing enough.
