How Blood Glucose Works

In simple terms, for the sake of our health, blood-glucose levels need to remain within certain levels. The body regulates these blood sugar levels using two mechanisms: hunger and insulin.

  • When blood-glucose levels fall, the brain causes us to feel hungry. Result? We eat food that is converted into glucose and our blood sugar levels rise. If we don't eat and blood-glucose levels fall too low, we trigger the condition known as hypoglycemia.

  • When our blood-glucose levels rise, the brain tells our pancreas to release insulin. Result? The insulin helps to disperse the glucose and our blood sugar levels fall. Without insulin to regulate a rise in blood-glucose, the amount of sugar in our bloodstream can become toxic, triggering the condition known as hyperglycemia.
Effect of Carbohydrate Foods on Blood Glucose Levels

When carbs are eaten and digested, they are converted to glucose and enter the bloodstream where they raise blood-glucose levels. How fast these carbs raise blood-sugar levels depends on their glycemic index value.

  • Individual carb-containing foods or (more commonly) carb-containing meals with a high glycemic index value cause a "spike" in blood-glucose levels. Meaning, our blood-sugar rises very fast, triggering an equally rapid response from the pancreatic gland which pumps out enough insulin to deal with the excess blood sugar. Result? Within an hour or so, the large secretion of insulin has dispersed all the excess blood glucose and then some. So we feel hungry again!!

  • Individual carb-containing foods or carb-containing meals with a low glycemic index value raise blood-glucose levels in a slower more sustained manner. So the pancreas responds by releasing a more moderate amount of insulin. Result? Hunger is kept at bay and we feel satisfied for longer.
Carbs and Blood Glucose Levels - Bottom Line

Not all carbohydrates cause a "spike" or rapid rise in blood sugar. Only carbs with a high glycemic value do this. Some diet "experts" imply that all carbs are bad for our blood-sugar levels. This is not true. Indeed, even the effect of higher glycemic index carbs can be mitigated by combining them with lower glycemic value foods.

Hydroxyurea : treatment for sickle cell...

(CIT): NIH Consensus Development Conference Sickle cell disease is an inherited blood disorder that affects between 50,000 and 75,000 people in the United States, and is most common among people whose ancestors come from sub-Saharan Africa, South and Central America, the Middle East, India, and the Mediterranean basin. Sickle cell disease occurs when an infant inherits the gene for sickle hemoglobin from both parents (Hb SS, or sickle cell anemia), or the gene for sickle hemoglobin from one parent and another abnormal hemoglobin gene from the other parent. Each year, approximately 2,000 babies with sickle cell disease are born in the United States. The condition is chronic and lifelong, and is associated with a decreased lifespan. In addition, approximately 2 million Americans carry the sickle cell trait, which increases the public health burden as this disorder is passed on to future generations. The red blood cells in people with sickle cell disease become deoxygenated (or depleted of oxygen), and crescent-shaped or "sickled." The cells become sticky, and adhere to blood vessel walls, thereby blocking blood flow within limbs and organs. These changes lead to acute painful episodes, chronic pain, and chronic damage to the brain, heart, lungs, kidneys, liver, and spleen. Infections and lung disease are leading causes of death. Pain crises are responsible for most emergency room visits and hospitalizations of people with sickle cell disease. Standard treatments for acute pain crises include painkilling medications, fluid replacement, and oxygen. In the mid-1990s, researchers began investigating the potential of hydroxyurea to reduce the number and severity of pain crises in sickle cell patients. Hydroxyurea is in a class of anti-cancer drugs and it acts to increase the overall percentage of normally structured red blood cells in the circulation. By diluting the number of cells that "sickle," it may, if taken on a daily basis, reduce their damaging effects. Hydroxyurea was approved by the FDA for use in adults with sickle cell anemia in 1998. However, there are a number of unresolved issues about the use of hydroxyurea, including a lack of knowledgeable providers who treat sickle cell disease, and patient and practitioner questions about safety and effectiveness, including concerns regarding potential long-term carcinogenesis.
