I'm a 43-year-old IT professional dealing with obesity and I've noticed that my fasting blood glucose level is at 148. I'm already on 1 tab of Asomex LT for hypertension which I take every night before bed. Can you suggest any medication or advice to help manage my high blood glucose levels? I'm starting to get a bit worried about it.

Fasting blood glucose should not exceed 100mgdl. The initial drug of choice for first line treatment of type 2 diabetes mellitus is Metformin 500mg. However, in order to get a more comprehensive understanding of your condition, you should undergo a panel of tests including FBS, PPBS, HbA1C, and URE. This data will help to curate a more effective treatment plan for you. You should also look into lifestyle modifications such as diet control, regular exercise, stress management and cessation of smokingdrinking (if you are a smokerdrinker).

While natural remedies and exercises can't increase breast size, they can improve the appearance and tone of your chest muscles, which can enhance the overall look of your breasts. Focusing on exercises that strengthen the pectoral muscles and a healthy diet can help you feel more confident and comfortable in your own body
