Blood glucose homeostasis pancreas

Common Questions and Answers about Blood glucose homeostasis pancreas


6452556 tn?1381422100 When you eat a meal, your blood glucose will increase which activates your beta cells to release insulin to then lower your blood glucose and vice versa. When you have diabetes your beta cells may lose some or all of their ability to tightly control blood glucose. So all of a sudden when you start taking glyburide, enough insulin is released to push glucose into you bodies cells.
Avatar m tn Your pancreas is not dead! Diabetes type 1 is when the immune system destroys part of the pancreas that produces insulin, but leaves the rest perfectly intact. Type 2 is when nothing is destroyed, but for some reason, you're either not producing enough insulin, or the insulin that you produce is not efficient enough. There's a clear distinction between the two, as type 1 is autoimmune 'disease'. In all cases the pancreas is still performing all the other functions correctly.
Avatar n tn Glucose in the blood is called blood glucose, also known as blood sugar. As the blood glucose level rises after a meal, the pancreas releases insulin to help cells take in and use the glucose. When people are insulin resistant, their muscle, fat, and liver cells do not respond properly to insulin. As a result, their bodies need more insulin to help glucose enter cells. The pancreas tries to keep up with this increased demand for insulin by producing more.
Avatar n tn Hi, the Hba1c is an average blood glucose reading for the past 3 months. So, the reading of 6.3 does coincide with an average blood sugar of 134. The Glucose level is a spot reading, at the time that the blood test was done. I presume it was a fasting level. Your blood sugar will vary during the day. Now, getting back to your hba1c. This is still too high. Consider a non-diabetic Hba1c will be < 5.0 and their average blood sugar will be < 100 (probably in the high 80s to low 90s.
Avatar f tn Thanks for your help! I appreciate your feedback! I was wondering about the reactive hypoglycemia and if that's what it could be. This lower blood sugar after eating didn't start until my blood sugars were under the normal limits all throughout the day. I realize it wasn't that low but it was lower than what I was used to. Also, I was wondering if you might know about normal insulin levels? She checked my insulin level and it was 6, she said 0-25 was normal???
Tbd Postprandial hyperglycemia is also one of the earliest abnormalities of glucose homeostasis associated with type 2 diabetes" So test 1-2 hours after a meal. As a pure guess, I'd think that once a month is sufficient - unless you change your diet or activity or other risk factors.
Avatar m tn Here's is what I think, and I'm using that term loosely, answers to your question. Diabetes occurs when a person's pancreas produces little or no insulin or when the body rejects the insulin that's produced. Now, there is insulin resistance. If you have insulin resistance, your muscle, fat, and liver cells do not use insulin properly. The pancreas tries to keep up with the demand for insulin by producing more.
Avatar f tn Here is clarification on glucose testing; a fasting glucose (GTT) or an oral glucose test (OGTT) measures glucose in your blood at the time of the test. It does not take into count what you levels were three months ago, a week ago, or the day before the test. The Hemoglobin A1c (HgbA1c or HbA1c) test measures your average glucose level over the past three months. The results are presented in % (percentile) where below 6% is considered normal.
Avatar f tn Sorry what is BG? Blood glucose?
Avatar f tn s pancreas is working overtime - although ineffectively - to produce insulin in an attempt to lower blood sugar. This additional maternal insulin doesn't cross the placenta, but the increased amount of glucose does! This in turn makes baby's pancreas produce additional insulin, which can decrease baby's blood sugar after devliery.
Tbd The pancreas stores the insulin until it is needed to move excess glucose out of your blood. Insulin unlocks the cells in the body to allow extra glucose into them for energy. Extra glucose that isn't used for energy is moved by insulin into fat cells for storage. If you eat too many carbohydrates over the years, your cells become more and more resistant to insulin and it takes more and more to keep your blood level down.
Avatar f tn However, your body can also break down protein to make glucose, and obviously there is some glucose in your body because your blood sugar levels are stable. On your ketogenic diet your levels are totally normal. However, on this diet there is very little demand on your pancreas. if you increase your carbs, depending on the health of your pancreas, you may or may not have high blood sugar levels. So we cannot know if you are diabetic. You do not have diabetic numbers on this diet.
Avatar n tn When reading your comments, it occurred to me that your symptoms, including the slightly low glucose reading on your glucose tolerance test sound more like hypoglycemia than diabetes. Hypoglycemia means that your blood sugar is too LOW, not high (diabetes).
863754 tn?1239144755 My aunt is in the hospital, as I type this, fighting to stay alive. After speaking with the doctors about her condition, I've discovered that they have absolutely no idea why she's dying. I'm posting here in the hopes of saving her life. For some reason, her blood glucose levels won't stabilize. They'll give her a shot of glucose to get her levels up, but in the matter of a few hours, it's back down to around 50 or 60 and they have to give her another shot.

Avatar n tn Then a week before Xmas (while still working) the blood glucose went higher and higher and he increased his insulin until new year when he was up to 10 & 10 with rapid being 6,6, & 8. Even with this regime the BG struggled to get below 15. Then after a big hypo (1.7) the BG has lowered again and he is on 10 protophane at night, 8 in the morning and no rapid again. Still he has unpredictable hypos and unexplained high numbers.
Avatar n tn I have been seeing an endocrinologist because I am constantly having low blood sugar readings and have had a high fasting blood glucose test of 8.3. My endocrinologist feels this may be due to my dysautonomia. She thought maybe reactive hypoglycemia because I am having low fasting glucose levels as well as high. I went for a 2hr OGTT today and I am feeling horrible after the test. My baseline was 4.8 @ 8:55 Given 75g of glucose to drink At 4.3 @ 9:25 At 4.8 @ 9:55 At 6.2 @ 10:25 At 6.
Avatar m tn 3-4 hours after meals, or when I'm hungry, I frequently get symptoms such as irritation, heart palpitations, asthma like symptoms feeling like I can't take deep breaths, extreme hunger... most of them go away as soon as I eat something. Now sounds like hypoglycemia (reactive or whatever) but when I check my blood glucose, it is around 100 a bit more which means it's not hypoglycemia. . What else may be causing this? My docs say it's not asthma.
798555 tn?1292787551 I know there is a few people here with blood glucose levels, weather diabetic or not. I'm not diabetic by the way, and really want to avoid it obviously. I'm just wondering if anyone has noticed if there glucose goes up when they are hypo thyroid per labs. It only makes sense to me as the pancrease might not completely do its insulin job when your hypo, so more sugar floating around in your blood.
