These nutrients are digested into
simpler compounds. Carbohydrates are used for energy (glucose). Fats are used for energy after they are broken into fatty acids. Protein can also be used for energy, but the first job is to help with making hormones, muscle, and other proteins.
Living with a chronic illness like type 2 diabetes can seem overwhelming at times. Sometimes you might feel that no one understands the stress that you feel day after day. If prolonged, these overwhelming feelings of anxiety, stress, and isolation can become a barricade in your quest for wellness.
It does not have to be this way. You must seek support to maintain control of your type 2 diabetes and to enjoy your life to the fullest. Whether your main support comes from your spouse, a close friend,...

hormones. Extra is stored in fat cells.
After a meal, the blood sugar (glucose) level rises as
carbohydrate is digested. This signals the beta cells of the
pancreas to release
insulin into the bloodstream. Insulin helps glucose
enter the body's cells to be used for energy. If all the glucose is not needed
for energy, some of it is stored in fat cells and in the
liver as glycogen. As sugar moves from the blood to
the cells, the blood glucose level returns to a normal between-meal
Several hormones and processes help regulate the blood sugar level
and keep it within a certain range
(70 mg/dL to 120 mg/dL). When the blood sugar level falls
below that range, which may happen between meals, the body has at
least three ways of reacting:
Cells in the pancreas can release
glucagon, a hormone that signals the body to
produce glucose from glycogen in the muscles and liver and release it into the
When glycogen is used up, muscle protein is broken
down into amino acids. The liver uses amino acids to create glucose through biochemical reactions (gluconeogenesis).
Fat stores can be used
for energy, forming
