If you have a medical condition that affects your red blood cells, it can potentially influence your A1C test results. For example, sickle cell disease and thalassemia can make the test unreliable. Recent blood loss, blood transfusion, or iron deficiency can also influence the results.
Can being sick raise your A1C?
Why Blood Sugar Spikes When You’re Sick
Your body releases stress hormones like epinephrine (also known as adrenaline) to fight the illness. These hormones can raise your blood sugar levels and increase the amount of insulin your body needs.
Do blood sugars go up when you are sick?
When you get sick — whether it’s a minor illness like a cold or a bigger problem — the body sees the illness as stress. To deal with the stress, it releases hormones that increase sugar in the blood. In one way, this is good because it helps supply the extra fuel the body needs.
What conditions affect A1C?
What Can Affect Your A1C Result?
- Kidney failure, liver disease, or severe anemia.
- A less common type of hemoglobin that people of African, Mediterranean, or Southeast Asian descent and people with certain blood disorders (such as sickle cell anemia or thalassemia) may have.
How much does illness affect blood sugar?
“Infection is a metabolic stress, and it raises your blood sugar,” Dr. Garber says. It can be hard to know how you will respond to each infection, he adds. Being sick can also lead to dehydration, eating differently, oversleeping, and losing track of your schedule — all of which can make diabetes management harder.
What causes A1c to go up?
If a person consistently has higher blood glucose levels over time, A1c levels go up because more red blood cells are coated with sugar. The test is representative of a 2 to 3-month average because once a red blood cell becomes coated with sugar, the link is irreversible.
Can flu cause high blood sugar?
Flu may raise your blood sugar levels, but sometimes people don’t feel like eating when they are sick and a reduced appetite can cause blood sugar levels to fall. It is important for people with diabetes to follow the sick day guidelines if they become ill.
Can blood sugar level increase without eating?
If you’re not eating due to an acute illness like the flu or an infection, it’s also common for your blood sugars to rise.
Can blood sugar rise without diabetes?
High blood sugar is the primary symptom that underlies diabetes, but it can also occur in people who don’t have type 1 or type 2 diabetes, either because of stress or trauma, or gradually as a result of certain chronic conditions.
Does stress affect A1c?
Acute stress can increase endogenous glucose production and impair glucose utilization; however, data from brief stressful events lasting only a few minutes and occurring a few hours before sampling suggest that this short-term process likely does not affect A1c .
How can I get my A1c down quickly?
Since exercise prompts your muscles to take up sugar from your bloodstream, it helps your blood sugar levels drop more quickly after you eat a meal. As you make exercise a regular habit, you’ll see a downward trend in your A1c numbers. Never miss your meds. You can reliably lower your A1c through diet and exercise.
What if my A1c is 14?
If the A1C is higher than that, and on diagnosis of type 2 it commonly is, the machine just reads >14%. How much higher is anyone’s guess. It could be 14.1% or it could be 20%. To clock a 14% you need a 24-7-90 (twenty four hours a day, seven days per week, for 90 days) blood sugar average of 355 mg/dL.
Can an infection cause diabetes?
Type 1 diabetes occurs when your immune system, the body’s system for fighting infection, attacks and destroys the insulin-producing beta cells of the pancreas. Scientists think type 1 diabetes is caused by genes and environmental factors, such as viruses, that might trigger the disease.
