Talk to Diabetologist on Diabetes Confirmation

I am male with 39 yrs of age and 96 kg weight with 5.5 ft height. Last year I found my fasting and 2hrs post meal suger in Prediabetic range but HBA1C 6.6. I changed my lifestyle and reduced weight upto 10 percent. Mu HBA1C was back at 5.8.

Unfortunately 6 months back I went for a surgery which stopped my walk and Intermittent fasting resulted in weight gain. Now my fasting is always at 120 to 122 and 2 hrs post meal is always at 155 to 160 (Chaecked multiple times) but my HBA1c has come 7.2.

1. Am I Diabetic or yetbe considered Prediabetic?

Do I need medications? or I should only give a try to lose weight without medication?

Please help me out.
