Fluctuations in blood sugar levels can happen in diabetes, but repeated episodes of very high or low readings usually suggest that your treatment or diet may need adjustment. The episodes of stomach upset with loose motions and lower abdominal pain are not a typical direct symptom of diabetes and may be due to infections, food intolerance, or sometimes side effects of medications such as metformin. Some people with diabetes can also have gut-related problems, but this needs proper assessment to confirm. It is important to keep a record of your blood sugar levels and gastrointestinal symptoms and discuss them with your doctor for proper evaluation and adjustment of treatment.

Your fasting levels (110-120 mg/dL) and post-meal levels (180-200 mg/dL) are slightly elevated, pointing towards prediabetes or early-stage diabetes. Please do not worry, as these levels are highly manageable. First-line generic medications like metformin are commonly prescribed to help your body utilise insulin better, while others like acarbose can specifically target post-meal spikes. However, the safest and most effective approach requires a personalised prescription based on your complete health profile and an HbA1c test. I highly recommend focusing on a balanced, low-sugar diet and daily exercise while consulting your doctor to determine the best medication plan for you.
