As folks with diabetes, we are sometimes informed that having an A1c in goal is a crucial aim in our diabetes administration. However are you aware why?
Have you learnt what your A1c goal is, find out how to decrease your A1c if wanted, and the way rapidly you may decrease your A1c safely?
These are the questions I’ll reply on this complete information on what an A1c is, find out how to decrease your A1c, and why decreasing A1c isn’t the one (or essentially the most effective) aim on the subject of diabetes administration.
What’s A1c?
The A1c, also referred to as hemoglobin A1c, HbA1c, glycated hemoglobin, or glycohemoglobin, is a blood take a look at that measures your common blood sugar during the last 2 to three months.
It’s not an “even common,” however fairly a weighted common, the place your blood sugar ranges over the previous couple of weeks depend just a little greater than your blood sugar ranges from 2 to three months in the past.
In line with the Nationwide Institute of Diabetes & Digestive & Kidney Ailments (NIDDK):
It’s essential to notice right here that the time period “regular A1c degree” on this context refers to folks with out diabetes. I’ll get again to what a “regular A1c degree” is for folks residing with diabetes under.
Easy methods to take a look at your A1c
Your physician or endocrinologist ought to examine your A1c often (usually each 3 to six months). The physician merely pricks your finger and takes a tiny blood pattern.
If the physician’s workplace has an A1c package, it’s best to get your end result earlier than your session is over. (Some places of work, nevertheless, will ship a blood pattern from the lab for processing.)
You can even purchase residence A1c kits (no prescription required) and do the take a look at your self. Dwelling A1c kits will be helpful if you happen to go for greater than 3 months between physician visits and need to control how your A1c is trending.
The house kits are typically correct inside plus/minus 0.5 proportion factors, which is greater than adequate to provide you a reliable end result.
The draw back of the house kits is that they require a bigger quantity of blood (typically, a number of giant drops) than an everyday blood sugar examine, and if you happen to don’t apply sufficient blood, you’ll get an error message and may have misplaced an A1c take a look at strip.
You will discover residence take a look at kits on Amazon and in some pharmacies. Make certain that your property A1c package is used previous to the expiration date.

Why it’s best to care about your A1c
A number of important research have proven that prime common blood sugars improve the danger of diabetes-related problems. Reducing your A1c to the really helpful vary will scale back the danger of diabetes-related problems.
In line with the landmark Diabetes Management and Problems Trial (DCCT) and the follow-up research referred to as the Epidemiology of Diabetes Interventions and Problems (EDIC), in folks with diabetes who used intensive therapy to maintain their A1c on the goal degree:
- Eye illness threat was lowered by 76 %
- Kidney illness threat was lowered by 50 %
- Nerve illness threat was lowered by 60 %
- Any heart problems occasion threat was lowered by 42 %
- Nonfatal coronary heart assault, stroke, or threat of dying from cardiovascular causes was lowered by 57 %
Attaining an A1c within the really helpful vary is, due to this fact, one of the essential issues you are able to do to enhance your long-term well being whenever you stay with diabetes.
In some instances, decreasing your A1c an excessive amount of might not be a good suggestion if it signifies that you improve how usually you expertise hypoglycemia (low blood sugar).
I’ll clarify why a measure generally known as “time-in-range” (TIR) is simply as essential as a low A1c later on this information.
Easy methods to decrease your A1c
Now that you’ve an intensive understanding of A1c, in addition to why taking a look at your A1c in isolation isn’t optimum, the plain query is:
How do you decrease your A1c whereas bettering or sustaining your time-in-range?
I’ll cowl what, in my expertise, are the 4 most essential issues you are able to do under, but it surely’s at all times really helpful that you simply begin by having a dialog together with your medical crew earlier than making adjustments to your diabetes administration.
Establish the principle “ache factors”
Whether or not you might be largely self-managing your diabetes or working carefully together with your medical crew, step one ought to at all times be to attempt to establish the principle “ache factors,” or the explanation why your A1c is larger than you’d like. The one possible way of doing that is by monitoring your blood sugars very carefully.
If you happen to put on a steady glucose monitor (CGM), you may take a look at your 7-day, 30-day, and 90-day blood sugar information to see if you happen to can spot any tendencies.
For instance, you would possibly discover that you’re working excessive from 1 a.m. to five a.m. each evening, each morning (as within the daybreak phenomenon, an early-morning improve in glucose degree), or each day after meals. Or maybe you at all times go low after train. All of us have totally different blood sugar patterns.
It’s additionally very doable that you just are working your blood sugar just a little too excessive on a regular basis and may gain advantage from adjusting your diabetes medicine.
Figuring out patterns like that makes it doable to pinpoint areas of potential enchancment so you can begin making a plan for find out how to restrict your excessive and low blood sugars.
If you happen to depend on guide blood sugar monitoring, it’s just a little trickier, since most individuals don’t monitor each 5 minutes. On this case, you would possibly attempt rising how usually you examine for some time, and possibly even checking in the course of the evening if you happen to get up anyway.
Most meters help you obtain information to your pc, or you may add these information to one among numerous app-based platforms. This may also help you see the info in a extra cohesive manner so you can begin searching for tendencies.
Create a plan in your diabetes administration
Now that you’ve a greater thought of what your “ache factors” are, you can begin making adjustments to your diabetes administration.
Your physician could recommend a unique medicine regime. For instance, some individuals are prescribed metformin to assist with the daybreak phenomenon. Others may have changes to insulin dosing or different drugs.
If you happen to’re utilizing insulin and constantly have excessive blood sugars within the morning, getting your blood sugar fluctuations and A1c down could be so simple as adjusting your nighttime basal (background) insulin.
Or, if you happen to run excessive each day after meals, your insulin-to-carb ratio could be off, and adjusting that could possibly be what units you on a path towards a decrease A1c. Till you acquire the info and do the evaluation, you haven’t any manner of figuring out this.
I need to make an essential level right here: rising your diabetes medicine shouldn’t be an indication of failure. It’s usually the most effective (and generally solely) technique to handle your blood sugar and produce down your A1c.
I alter my insulin up and down on a regular basis after I change my food plan or train routine. The flexibility to regulate your medicine is a crucial device in your diabetes toolbox and one thing it’s best to at all times talk about together with your medical crew.
Perceive diet and alter your food plan
What you select to eat and drink can have a serious influence in your waistline, temper, and well-being, in addition to your blood sugar ranges.
All macronutrients (carbohydrates, proteins, and fat) can have an effect on your blood sugar to a point, so creating understanding of how they have an effect on your blood sugar will allow you to be proactive and stop blood sugar swings.
Carbohydrates (carbs)
Carbohydrates have the best influence in your blood sugar, which is why many individuals with diabetes can profit from following a lower-carb food plan. The less carbs you eat, the much less insulin it’s worthwhile to take, which makes diabetes administration simpler.
Nonetheless, you don’t should observe a low-carb food plan if it doesn’t give you the results you want — bodily or mentally.
As I wrote in my piece about which food plan is greatest for folks with diabetes, it is vitally doable to have nice blood sugar administration on a medium- (and even high-) carb food plan, so long as you experiment, take notes, and be taught to take the fitting quantities of insulin for the carbs you might be consuming.
It is rather essential to understand that all of us react in a different way to carbs, so you need to discover the food plan and meals which might be best for you.
For example, folks react very in a different way to carbs like oats or candy potatoes. Some folks can eat oats with solely a small improve in blood sugar, whereas others see a fast spike.
By merely figuring out this, folks having difficulties with a sure kind of carb can select to cut back their consumption or reduce it out of their food plan altogether.
Protein and fat
Whereas carbs have an effect on blood sugar most importantly, protein and fats additionally have an effect. Some, like Dr. Sheri Colberg, PhD, one of many world’s main voices on diabetes and train, suppose that solely taking a look at carbs when estimating blood sugar influence (and dosing insulin) is an outdated and inefficient technique to pursue diabetes administration.
Within the opinion of some consultants, it’s best to focus extra on whole energy (learn extra about calorie counting and diabetes right here).
The important thing factor to pay attention to is that when protein and particularly fats are consumed with carbohydrates, the power from the meal will likely be launched extra slowly, which signifies that your blood sugars will likely be impacted extra slowly as nicely.
Whereas I don’t imagine your diabetes administration ought to utterly dictate how you reside your life and which food plan you select to observe, it may be price evaluating which meals decisions make life simpler for you.
By making a aware selection of which sort of diet plan to observe (nearly all of the time), you may extra simply set up wholesome habits that may profit not solely your general well being but in addition your each day blood sugar ranges, and thereby your A1c.
Enhance exercise (train)
Whereas train is crucial for constructing and sustaining good well being and bettering insulin sensitivity, it may be a double-edged sword if it consistently throws your blood sugars for a loop. Not solely is that very irritating, scary, and annoying, however it might probably additionally have an effect on your A1c and time-in-range.
The secret is to know how several types of train have an effect on your blood sugar ranges and, if you happen to use insulin, to be taught your system for balancing insulin and meals round exercises.
Cardio
Cardio, akin to brisk strolling, jogging, swimming, biking, or dancing, are all wonderful varieties of train. As little as 20 to half-hour a day could make a big distinction on the subject of bettering insulin resistance and managing blood sugar ranges.
Not solely does train scale back blood glucose throughout train, but it surely additionally improves your insulin sensitivity for hours after your exercise, which means that you simply want much less insulin.
If you happen to deal with your diabetes with insulin, you’ll have to handle your insulin ranges so that you don’t expertise exercise-induced hypoglycemia. This comes all the way down to decreasing your insulin considerably or consuming carbs earlier than your exercise.
For many individuals, it might not be essential to “carb up” to do as much as 60 minutes of steady-state cardio, however there will be conditions by which decreasing insulin earlier than train can’t be achieved, so further carbohydrates have to be consumed.
And it’s additionally essential to keep in mind that totally different folks react in a different way primarily based on quite a lot of components, akin to insulin sensitivity, timing of their final insulin dose, and health ranges, so this might not be the case for you.
Resistance coaching
Including resistance coaching to your each day routine, akin to free weights, weight machines, resistance bands, or body weight workout routines, will be instrumental in rising your insulin sensitivity and decreasing your A1c.
Whereas cardio will decrease blood sugar throughout train and probably as much as about 48 hours after train, resistance coaching can improve insulin sensitivity for for much longer.
It is because muscle mass work as little “glucose tanks” and also you’ll retailer extra glucose in your muscle mass fairly than sending it on to your bloodstream. The extra muscle mass you’ve gotten, the higher your insulin sensitivity.
Simply bear in mind that some folks will see a short lived improve in blood sugars throughout intense resistance coaching, fairly than a lower.
The rationale for the rise in blood sugar is that the improved insulin sensitivity from exercising is surpassed by your physique’s elevated glucose manufacturing from the adrenaline launched by the exercise.
This adrenaline causes your liver to interrupt down glycogen to create glucose, and your physique is producing the glucose sooner than you should utilize it.
For an in depth information, learn: How Resistance Coaching Impacts Your Blood Sugar.
The shorter-term results apart, as a result of resistance coaching is so efficient at rising your insulin sensitivity, it’s an effective way to decrease your blood sugar and A1c constantly.
If you happen to train often, the impact of exercising overlaps from one exercise to the subsequent, and also you primarily obtain a everlasting improve in insulin sensitivity. (You’ll want to work together with your healthcare crew to regulate your therapy routine to keep away from lows out of your improved insulin sensitivity.)
Preserve a wholesome weight
If you’re obese, dropping as little as 5 to 10 % of your weight may also help with numerous well being markers, together with A1c ranges.
In a single research, folks with kind 2 diabetes who misplaced this quantity of weight lowered their A1c by a mean of 0.5 %.
How rapidly are you able to decrease your A1c?
For the reason that A1c take a look at reveals your glucose over the earlier 2 to three months, it can take not less than a couple of weeks of constant dietary and train adjustments to see the outcomes mirrored in your A1c degree.
The precise timeframe will fluctuate primarily based on particular person components such because the depth of the adjustments and the way your physique responds.
(That is merely because of the long-term nature of the take a look at — the enhancements will mirror in your glucose a lot sooner.)
On this video, I clarify how I lowered my A1c in 30 days by following 5 easy steps:
Why you shouldn’t decrease your A1c too rapidly
It may be a good suggestion to strategy decreasing your A1c with a little bit of warning. Simply as crash weight-reduction plan isn’t wholesome, there will be some critical well being dangers related to decreasing your A1c too rapidly.
I turned to Dr. Anne Peters, MD, Director of the USC Scientific Diabetes Program, and Professor of Scientific Medication Keck College of Medication of USC for a proof:
Can your A1c be too low?
As described above, the reply to this query relies upon nearly solely on how usually you expertise hypoglycemia. If you happen to (nearly) by no means expertise hypoglycemia and your A1c is at goal, this might recommend that your diabetes administration is efficient.
Nonetheless, this doesn’t imply an especially low A1c is at all times secure or fascinating. Every particular person’s perfect A1c degree can fluctuate, and components akin to their threat of hypoglycemia unawareness, how lengthy they’ve had diabetes, age, and general well being must be thought of.
If you happen to usually expertise hypoglycemia, that may end in an “artificially” low A1c studying as a result of your hypoglycemia occasions are decreasing your blood sugar common.
In that case, specializing in rising time-in-range is far more essential than additional decreasing your A1c. The truth is, you might even profit from a barely larger A1c with fewer blood sugar fluctuations.
It’s additionally essential to notice that decreasing your A1c under the widely really helpful vary of 6.0 to 7.0 % hasn’t been confirmed to offer any well being advantages. Due to this fact, a really low A1c shouldn’t be a aim in itself.
What is an effective A1c goal?
Now that you’ve your A1c quantity, let’s take a look at what that quantity truly tells you. The American Diabetes Affiliation has established the next tips:
| A1c Stage | What It Means |
| Lower than 5.7 % | Regular (minimal threat for kind 2 diabetes) |
| 5.7 % to six.4 % | “Prediabetes,” which means in danger for creating kind 2 diabetes |
| 6.5 % or better | Recognized diabetes |
This does NOT imply that you simply want an A1c of lower than 5.7% if you happen to’re residing with diabetes. It signifies that if you happen to do NOT stay with diabetes, your A1c is predicted to be under 5.7%.
There are totally different suggestions for what an applicable A1c is for folks residing with diabetes.
I had an opportunity to ask Dr. Peters, in addition to Gary Scheiner, MS, CDCES, proprietor and Scientific Director of Built-in Diabetes Providers and creator of Assume Like a Pancreas, what their views are on A1c goal:
Dr. Peters:
Scheiner:
Learn extra about A1c in: What’s a “Regular” HbA1c? and What’s a Harmful Stage of A1c?
Of their Requirements of Care in Diabetes — 2024, the American Diabetes Affiliation recommends an A1c goal of under 7.0 % for adults residing with diabetes.
An A1c of seven.0 % roughly interprets to a mean blood sugar of 154 mg/dL (8.6 mmol/L) as you may see from this conversion chart (eAG stands for “estimated common glucose”).
| A1c | eAG (mg/dL) | eAG (mmoL) |
| 5 % | 97 | 5.4 |
| 6 % | 126 | 7.0 |
| 7 % | 154 | 8.6 |
| 8 % | 183 | 10.2 |
| 9 % | 212 | 11.8 |
| 10 % | 240 | 13.3 |
| 11 % | 269 | 14.9 |
| 12 % | 298 | 16.5 |
| 13 % | 326 | 18.1 |
| 14 % | 355 | 19.7 |

A1c vs. time-in-range
A1c has lengthy been thought of the most effective measure of diabetes administration as a result of it was probably the most correct device for observing long-term blood sugar tendencies. This has modified with the introduction of steady glucose monitoring (CGM).
Through the use of a CGM, now you can get a really correct image of not solely your common blood sugar, however your blood sugar fluctuations as nicely.
This makes it doable to trace one other key element of diabetes administration: time-in-range.
Time-in-range refers back to the proportion of time throughout which your blood sugar is inside a selected vary. To see why time-in-range is essential, check out the three strains within the graph under.
All three strains present a mean blood sugar of about 154 mg/dL (8.6 mmol/L, which equates to an estimated common A1c of about 7.0 %) however with very totally different fluctuations. I feel we might all choose our blood sugar to observe line 3 fairly than line 1.
Graph used with permission from diaTribe.
Some tips state that your blood sugar vary ought to be set to 70 to 180 mg/dL (3.9 to 10 mmol/L), however you might discover that to be too broad or slim of a spread for you.
On this interview with a number of diabetes consultants, most suggest that you simply spend lower than 3 % of the time under 70 mg/dL (3.9 mmol/L) and fewer than 1 % of the time under 54 mg/dL (3 mmol/L). Nonetheless, in addition they agree that the precise time spent in vary must be individualized.
On common, the consultants didn’t anticipate the final diabetes inhabitants to be in vary greater than 50 % of the time at most, so speaking about incremental enchancment makes extra sense than setting a set quantity.
Easy methods to measure time-in-range
If you happen to put on a CGM, your time-in-range metrics ought to be listed whenever you obtain your information (as within the instance from a Dexcom CGM under).
Some CGM gadgets provide alerts when glucose ranges are predicted to enter or depart the goal vary, which might permit customers to reply proactively and spend extra time in vary.
(Click on to increase.)
If you happen to don’t use a CGM, all you are able to do is take a look at your guide blood sugar measurements and take note of the quantity of excessive and low blood sugar readings outdoors of your goal vary.
What’s an appropriate excessive and low is one thing you need to talk about together with your medical crew.
What’s extra essential: a low A1c or a excessive time-in-range?
Ideally, you’d have an A1c under 7.0 % accompanied by low blood sugar variability (excessive time-in-range). A very good normal guideline is:
- The upper your A1c, the extra essential it’s to concentrate on getting it down.
- The decrease your A1c, the extra essential time-in-range turns into.
In case your A1c is under 6.0 to 7.0 %, specializing in rising your time-in-range will most likely have a bigger optimistic well being influence than decreasing your A1c additional.
So, is A1c one of the simplest ways to gauge whether or not your diabetes administration is on observe? Not essentially, however to cite Scheiner:
Closing ideas: My perspective on A1c as an individual residing with diabetes
I’ve a really ambivalent relationship with my A1c myself. I’ve been residing with kind 1 diabetes for over 20 years, and my A1c shouldn’t be one thing I take into consideration in my each day life.
Nonetheless, each 3-6 months after I see my endo, I get just a little anxious as a result of receiving your A1c can really feel loads like getting your diabetes report card.
And, fairly actually, that’s actually foolish. My A1c quantity doesn’t mirror what’s been occurring in my life for the final 3 months. It doesn’t inform me how a lot effort I’ve put into managing my diabetes and it doesn’t outline me as an individual. It’s supply of knowledge, nothing extra.
Nonetheless, we have a tendency to have a look at it and choose, good or unhealthy, how we’ve achieved with our diabetes administration. However we actually shouldn’t!
That doesn’t imply that I feel we shouldn’t get our A1c checked. I completely suppose we should always, however we additionally want to know what it means in addition to why we should always look past the A1c quantity. I hope this information has given you the information and instruments to take action.
