How to track HbA1c progress weekly

Feb 2, 2026

HbA1c reflects average blood sugar over 2-3 months, so true weekly tracking requires proxy methods like daily glucose logs converted to estimated trends. This blog equips diabetes managers in India with practical tools for consistent monitoring without lab visits every week.

Why Track HbA1c Weekly?

Direct HbA1c tests aren't weekly due to their long-term nature, but estimating progress via daily fasting/post-meal glucose and patterns predicts changes early. Spotting rises from carbs or stress lets you tweak diet/exercise fast, aiming for 0.2-0.5% drops monthly toward <5.7% reversal. Ideal for prediabetes plans like your 90-day action roadmap.

Tools for Weekly Estimation

Use affordable glucometers (₹500-2000 in Bengaluru) plus apps for conversion—HbA1c ≈ (28.7 × average glucose) - 46.7 mg/dL.

  • Glucometer Routine: Test fasting (aim <100 mg/dL), 2-hr post-meal (<140 mg/dL), bedtime 4x/week. Log 7-day averages.

  • Apps: MySugr, HealthifyMe, or BeatO—input readings for eAG (estimated average glucose) graphs predicting HbA1c.

  • CGM Option: Freestyle Libre (₹5000/14 days) for continuous data if budget allows; tracks trends 24/7.

  • Home HbA1c Kits: Weekly point-of-care like A1CNow (₹2000/test) for spot checks, though less common in India.

Step-by-Step Weekly Tracking Plan

  1. Sunday Baseline: Fast 8 hours, test glucose; weigh; note sleep/stress.

  2. Daily Logs: 3 readings/day (fasting, post-lunch, post-dinner); photo meals for patterns.

  3. Mid-Week Calc: Average week's glucose → eAG → estimated HbA1c via formula or app.

  4. Sunday Review: Compare to prior week; adjust (e.g., more millets if >126 mg/dL fasting).

  5. Monthly Validate: Lab HbA1c to confirm estimates.

Week Metric Target Proxy from Glucose Avg
Fasting <100 mg/dL Predicts 0.1% HbA1c drop/week 
Post-Meal <140 mg/dL Ties to carb tweaks
eAG <126 mg/dL Equals ~5.7% HbA1c 


Tips for Indian Lifestyles

Pair with millet-focused meals and yoga from your prediabetes plan—monsoon walks? Indoor brisk pacing. Track gut health via consistent bowels, as microbiome aids control. Share logs with docs via WhatsApp for feedback.

Common Pitfalls

Anemia or infections skew readings; test iron levels if inconsistent. Don't obsess daily—weekly averages smooth fluctuations.
