I'm 45 and my fasting and PP sugar levels spiked. Why?

Ans: All is Good.
Keep up the good work respecting your body

Ans: As your blood sugar levels are out of range, medication needs to be continued. Abnormal blood sugar levels can be lowered gradually with dietary modifications. A balanced Diet will be focused on whole, nutrient-dense foods, complex carbohydrates like whole grains (brown rice, quinoa, oats), legumes, and vegetables. Include healthy fats like avocados, nuts, and olive oil in your diet .Lean Proteins like fish, poultry, tofu, and beans will blunt your glycemic index. Limit sugary foods, refined carbs, and saturated fats. Stay physically active which improves insulin sensitivity and helps manage blood sugar levels.

Ans: Please let me know your weight and BMI as well.
It seems that you are developing insulin deficiency and resistance both.
After certain period, the oral medications become less effective. In such situations, it might beneficial and important to get started on Insulin.

The sudden spikes in sugar levels could also be due to stress or altered sleep pattern or change in dietary factors. However, that would not explain such as spike for long.

Please consult your physician and get on steps needed for effective sugar control.

Ans: The level of blood sugar you have indicated are suggestive of diabetes mellitus type 2 and the metformin you are taking is clearly insufficient.

Ofcourse, need to have more dietary modifications and increased physical activity. Get body weight within normal range (please see previous answer if you wish to understand more).

Please do following:
1. A comprehensive blood test. Specially when people have diabetes, there are chances of high Bp, deranged lipid profile. and other blood parameter changes.
2. Please get HbA1c done along with fasting adn 2 hr after breakfast blood sugar levels.
3. Your medications need to be increased as currently, the sugar levels are high. There is a concept called, legacy effect. which essentially mean a tight and early control in blood sugar results in better diabetes outcome in long run. The Hba1c should be less than 7, preferably around 6.5% to reduce the possibility of macro and microvascualr complications of diabetes.
4. Do charting of your blood sugar level for some time, with Glucometer. May consider CGMs (Continuous Glucose monitoring), which provides 14 day reading for every five minutes of sugar level in once body. This may help a physician to suitably modifiy your medication.
5. Visit a physician with above set of information.
