If you’re anything like me, the first time you’ve heard about the glucose tolerance test (GTT) was probably in the context of pregnancy.
Since the test’s goal is to see how your body reacts to glucose, you want to make sure that the baseline is as normal as possible, so try to eat like you normally would several days before the test. I was given the oral glucose tolerance test (OGTT), which is the most common GTT for those who are not pregnant (the test for pregnant women is also oral but the process is somewhat different). In addition to blood-glucose test, A1C test has numerous benefits, which help diabetes individuals to efficiently achieving their target. Assess diabetes treatment - how well it is going on, help confirm whether the on-going treatment regimen is suiting you or need any modification. Fix healthy choices - A1C not only helps assess your diabetes medication; additionally, help to assess other lifestyle changes you have just adopted.
Improve diabetes treatment - once you have achieved your target a1c, then you can try for more stringent targets and improvise your treatment plan to achieve it. Avoid diabetes complications - achieving good A1C range will stop various diabetes complications such as nerve damage, eye problems, oral problems, heart attack, sexual dysfunction, and depression. Diagnose pre-diabetes & diabetes – a1c test can be an useful tool for early diagnosis of pre-diabetes, and diabetes. International organization recommends A1C test as one of the tests to diagnose pre-diabetes and type-2 diabetes.
The blood-glucose test only provides a glucose level at that instead based on what you have ate on past hours, stress level, sleep quality, and any illness. You know diabetes type 2 develops slowly for months, during this period your blood-glucose level may fluctuate largely, and you may miss out the high level. Still, impaired glucose tolerance and impaired fasting glucose tests are important test for diabetes diagnosis.
The Diabetes Control and Complications Trial (DCCT) Study Findings; Intensive blood-glucose control reduces the risk of eye disease by 76%, kidney disease by 50%, and nerve disease by 60%. Epidemiology of Diabetes Interventions and Complications (EDIC) Study Findings: Intensive blood-glucose control reduces the risk of any cardiovascular disease events by 42%, nonfatal heart attack, stroke, or death from cardiovascular causes by 57%. Norfolk cohort of European Prospective Investigation of Cancer and Nutrition (EPIC-Norfolk) Study shows that those people with a 6% (considered normal) compared to those with a 5%, had a 28% increase in cardiovascular death.

Friends were telling me about this test they had to undergo to determine whether they are at risk for gestational diabetes, and I figured that this test will not be relevant for me for quite a while. When my doctor diagnosed PCOS, he recommended taking the glucose intolerance test to understand whether I suffer from Insulin Resistance (IR). You will then need to avoid eating and drinking for 8-12 hours before the test, and of course you will not be allowed to eat during the test either. The first step in the test is to take your blood sample to get a baseline of your fasting insulin levels. The good news is that physical activity, healthy lifestyle and weight loss can help the body process insulin better.
A1C test helps best understand diabetes treatment, manage diabetes better and prevent diabetes complications. Even many errors in your home glucose test became known and help you to correct it (value for your money, time and efforts). If your A1C result is not within the target, then you may need to change for more effective diabetes treatment.
Additionally, if your a1c is not in a healthy range, then you can change your lifestyle to stop its progression towards pre-diabetes and later to diabetes. Because, a1c has some drawbacks due to anemia or other conditions causing false, low and high in some individuals. A1C has a strong relationship with the blood-glucose level; increase in glucose level will reflect in an increase in A1C. In participants who had some eye damage at the beginning of the study, tight management slowed the progression of the disease by 54 percent. While not all women with PCOS have insulin resistance, insulin resistance is considered one of the causes for PCOS, so it was important to uncover whether this was the cause in my case. I erred on the side of caution and fasted 12 hours, so by the time I got to my 9am appointment, I was starving. Women who are diagnosed with both PCOS and insulin resistance are often prescribed Metformin, an anti-diabetic drug that often helps regulate their cycles and increase their likelihood of getting pregnant. Since insulin resistance can also lead to type 2 diabetes or pre-diabetes, finding out about it early on can also help prevent or delay the onset of the disease.

I was handed a chilled drink that tasted like a very sweet, low-quality lemon-flavored soft drink. As many as 70% of women with PCOS are insulin resistant, so if you know or suspect you have PCOS, I highly recommend taking the Glucose Tolerance Test early on in your fertility journey. It had 500 ml of liquid and 75 grams of glucose in it, which is the typical amount of glucose used in these tests.
While I ended up being in the 30% whose PCOS is not IR-related, I’m still glad I took the test.
In case you were wondering, 75 grams of glucose is equal to 19 teaspoons of sugar and 300 calories. After all, it is a relatively minor inconvenience that could have a significant impact on your fertility treatment plan. You need to drink the whole thing in five minutes, and after two minutes I already downed two thirds. At that point I was quite sugared out, so I drank the remainder more slowly and agreed with myself that this will not become my drink of choice going forward. All in all, though, the drink wasn’t as disgusting as I expected it to be, and I didn’t feel too nauseated or lightheaded (which some people complain about).
That is when the waiting begins – for the next 2-3 hours, a blood sample will be taken from you every 30-60 minutes to see how efficiently your body processes all that sugar.
In my case, the test lasted two hours and the nurse took my blood samples 60 minutes and 120 minutes after drinking the liquid. After my blood was drawn for the last time, I could finally go home and eat something, but I was no longer hungry – after ingesting so much sugar, I just didn’t feel like having anything for a few more hours.
