Healthy digestion and converting foods into energy
To understand diabetes, it helps to know how our bodies handle the sugars and energy found in our food and drinks.
- Los alimentos se descomponen y se separan en nutrientes dentro del aparato digestivo.
- Carbohydrates in our foods are broken down and converted to a usable type of sugar, most often glucose. Blood circulates this glucose throughout the body to provide energy to cells or to store it as fat to use later. (Fat is essentially "stored energy.") The body uses energy stored in glucose to move, exercise, heal, grow and think.
- Insulin is needed for the body to use glucose. Cells in the pancreas respond to the higher levels of glucose in the blood by producing insulin. With the help of insulin, cells throughout the body absorb glucose and use it for energy.
In people with diabetes, this process can go wrong in two ways. Either:
- There isn’t enough insulin. The pancreas isn’t producing enough insulin to respond to the glucose in the blood and blood sugar levels rise, or
- Cells are resistant to the insulin. The cells no longer respond to the insulin signal to take up glucose from the blood and blood sugar levels rise.
People with diabetes may have the following symptoms when their blood sugar is extremely high:
- Sequedad de la boca y la lengua
- Sed excesiva
- Aumento de la micción (al principio del síndrome)
- Pérdida de peso
