Blood Sugar (Definition)

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

Help please. Could drinking pepsi max before a blood glucose test effect the results?

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.

Water and glucose: When you drink water, your body gets rid of the excess (through urination) quickly. It is very hard to dilute your blood, and your glucose is not affected by water intake.

Is it okay to drink water when fasting for blood work?

Is it okay to drink water when fasting for blood work?

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"?

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.

How can the amount of water you drink affect blood glucose levels?

Dehydration: Can increase blood sugar if you have diabetes. Water intake will temporarily dilute your blood sugar level, but only for a very, very short time before your body readjusts.
