Your current fasting
sugar of 136 after starting treatment is a good improvement from 309, showing that your medicine and lifestyle are helping.
For a person with
diabetes, the general goal is a
fasting blood sugar between 80 and 130 mg/dL and a post-meal (2 hours after eating) level below 180 mg/dL. These values keep long-term complications under control while avoiding low sugar.
Continue taking your prescribed tablet regularly, eat early dinners, include more vegetables and protein, and walk daily for at least 30 -45 minutes. Avoid sweets, fried food, and excess rice. Recheck fasting, post-meal, and
HbA1c every 3 months to monitor progress.
You are moving in the right direction. Keep up the consistency. For a detailed review and safe plan, I can assess your case here on Practo.
