Your fasting level of 143 mg/dL and postprandial level of 185 mg/dL are elevated, indicating diabetes, but they are highly manageable. Please do not worry. While first-line oral medications like metformin are commonly prescribed to help lower these numbers, the exact medication and dosage must be tailored to you. I cannot safely prescribe medication without evaluating your overall health, kidney function, and HbA1c levels through a physical consultation. Please schedule an appointment with a doctor for a proper evaluation. In the meantime, adopting a balanced, low-sugar diet and engaging in regular light exercise, like walking, will help start bringing your levels down safely.
