Can You Drink Water Before A Fasting Blood Glucose Test
Yes: Water is fine before a blood glucose test, but don't eat any food or drink other liquids which might falsely elevate the glucose level in the blood.
The blood sugar concentration or blood glucose level is the amount of glucose (sugar) present in the blood of a human or animal. The body naturally tightly regulates blood glucose levels as a part of metabolic homeostasis. Glucose is the primary source of energy for the body's cells, and blood lipids (in the form of fats and oils) are primarily ...Read more
I've got a glucose blood test tomorrow morning and have to fast 10 hours before and was wondering whether you can drink water?
Yes: Water is fine; nobody wants you to be dehydrated just for some blood tests, but they don't want you to take any food or other fluids which may elevate your blood sugar.
GTT: If you are talking about glucose tolerance test, you may drink a little water after the glucose drink. Consult this site for information, especially about preparing for the test. Http://www. Mayoclinic. Org/tests-procedures/glucose-tolerance-test/basics/definition/prc-20014814
Not a big deal: The amount of water is not terribly important - 12-16 oz should be fine. Be sure you are fasting (not eating) for the required number of hours.
Yes: Water has no carbohydrates (the part of food that causes a rise in blood sugar) so there is no reason you can't drink it before a blood sugar test.
Fasting Blood Test: Yes, you can drink water and eat no food for your test.
Yes: Plan water no lemon or additives can be taken before a fasting blood test.
Yes: In fact you should drink a normal amount of non-caloric liquids to avoid becoming dehydrated, which can elevate blood sugar.
Yes it can: Pepsi Max does not contain sugar. Pepsi Zero Sugar (previously known as Diet Pepsi Max & Pepsi Max is sweetened with aspartame. Diarrhea is a possible side effect of aspartame & Sucralose. REF: http://www. Livestrong. Com/article/450435-diet-soda-diarrhea/ However, some people have a release of insulin after ingesting these artificial sweeteners & this can lead to drop in blood sugar level.
No: Water will not interfere with glucose testing.
Yes: Drinking water is fine unless directed specifically by your physician to avoid it. Fasting lab is looking for blood sugar and cholesterol which would be affected by coffee, food, and milk. I usually recommend to my patients to take their routine meds even when fasting except for medications that would affect the blood sugar.
Fasting blood sugar 181.8, hba1c > 7%, taking all vitamins, exercise 6 hrs/week, eat no sugar, eat high fibre, drink water, juice, wt. 67kilo, ht 5'5"?
Look into Paleo: Your lab numbers suggest you're on the path to diabetes. Even though you don't eat "sugar" any fiber or starch that your body can digest turns into sugar and fruit juice is sugar. Even things like diary that is thought of as healthy has sugar (lactose is a type of sugar). A person with lab numbers like yours has to limit all sugars and heal the damage. The paleo approach can help you do both.
For two weeks I haven't felt hunger or thirst but I drink water and eat once a day anyway. My doctor does not know what it is. I took blood test today?
Watch this: Relax, Fred. This is fairly common and means nothing. You can reassure yourself about your physical health by going a day or so just drinking water; you'll get hungry. I suspect there's something going on in your life that may be making you sad; if you start having a sleep disturbance or sad moods, this may be dysthymia / depression for which early treatment's important.
Doc said I had ketonuria and in my blood test I had low potasium I eat normally and drink water so why is that? Doctor said I need urine test again
This is serious: Anyone can have +1 ketones in the urine from missing a meal, but more is worrisome. Please repeat. Low blood potassium reflects illness rather than habits or lifestyle. I am trusting you are not taking any medications that might cause this. A good history and phyiscal exam is next, and likely some checks of hormones and renal concentrating ability / tubular function.
