Can you help me understand if it's okay to drink water before getting a non-fasting blood sugar test? I'm also wondering if it's necessary to wait a full 2 hours, or is an hour and a half sufficient before getting it checked?

For a non-fasting blood sugar test, you can drink water, but avoid eating anything for at least 1-2 hours before the test; however, if you've had a meal, waiting for 2 hours is ideal, but 1.5 hours may also be acceptable, consult with your healthcare provider or lab technician for specific guidance.

Drinking Water Before Test:
- It's perfectly fine to drink water before a non-fasting blood sugar test. Water does not affect blood sugar levels and helps keep you hydrated.
-
Timing for Blood Sugar Test:
- The standard recommendation is to wait about 2 hours after eating for a post-meal blood sugar test. This provides an accurate measurement of how your body manages glucose.
- Waiting only 1.5 hours might not fully reflect peak blood sugar levels, which typically occur around 2 hours post-meal.
-
General Advice:
- Follow any specific instructions from your healthcare provider.
- If unsure, sticking to the 2-hour window is generally advised for reliable results.
Key Points:
- Drinking water is safe and encouraged.
- The 2-hour wait is standard for non-fasting blood sugar tests.
- Consult your doctor for personalized advice if needed.

View allI'm really worried about my TSH level, which is at 36.28. I've felt super depressed and can't stop wanting to eat more. I'm currently on a 100 mcg tablet, but should I be thinking about increasing it? I try to exercise daily for about 30 to 40 minutes. Since I'm staying in a hostel, what kind of food choices should I be making to help get my thyroid under control? Also, I can't seem to lose any weight. Any advice?

I'm really concerned because over the last six months, I've noticed my face and neck skin turning dark. I used to have a lighter complexion, but now this change has really affected the areas around my neck, jaws, and chin. On top of that, the skin on my cheeks is also starting to darken. I'm also managing diabetes, so I'm wondering if there could be a connection. What might be causing this, and is there a way to reverse it?
