Summary Introduction
To explain: The way in which a glucose-rich snack help.
Introduction: Diabetes mellitus is a group of metabolic disorder in which the sugar level is high in the blood for a prolonged period. During this condition, the beta cells of the pancreas produce a little or no insulin. Diabetes mellitus is classified into type 1, type 2, and gestational diabetes. Type 1 diabetes (insulin-dependent diabetes) is the condition in which the insulin is not produced by the body due to the destruction of beta cells of the pancreas.

Marianne has type 1 diabetes. One day, after accidentally injecting herself with too much insulin, she starts to shake and feels confused. Following her doctor’s suggestion, she drinks a glass of orange juice—a ready source of glucose—and soon her symptoms subside. What caused her symptoms? How would a glucose-rich snack help?

- Figure 37.11 Pancreatic tumors may cause excess secretion of glucagon. Type I diabetes results from the failure of the pancreas to produce insulin. Which of the following statement about these two conditions is true? A pancreatic tumor and type I diabetes will have the opposite effects on blood sugar levels. A pancreatic tumor and type I diabetes will both cause hyperglycemia. A pancreatic tumor and type I diabetes will both cause hypoglycemia. Both pancreatic tumors and type I diabetes result in the inability of cells to take up glucose.arrow_forwardAddisons disease develops when the adrenal cortex does not secrete enough mineralocorticoids and glucocorticoids. President John F. Kennedy was diagnosed with the disease when he was a young man. Before he started treatment with hormone replacement therapy, he was hypoglycemic and lost weight. Which missing hormone was responsible for his weight loss? How might Addisons disease have affected his blood pressure?arrow_forwardFor our patient John with diabetes type II, he can make insulin but his body cells can be resistant to this insulin. Note: activated insulin receptors will activate glucose receptors. John takes a drug called metformin, in conjunction with regulating his diet and exercising. This drug has two main effects. First, it helps reduce hepatic (liver) production of glucose. Second, it helps cells become more sensitive to insulin. Explain how these two effects of metformin can help John.arrow_forward
- Explain the functions of insulin. Why do you think a hormone such asinsulin is required to carry out these functions?arrow_forwardIn type II diabetes, insulin is produced but is nonfunctional. These individuals are described as “starving in the sea of plenty” because their blood glucose levels are high, but none of the glucose is transported into the cells. Describe how this leads to malnutrition.arrow_forwardA woman affected by type 1 (insulin-dependent) diabetes miscalculates and injects herself with too much insulin. She soon begins to feel confused and sluggish. She calls for medical assistance and injects herself with the glucagon her doctor prescribed for such an emergency. When an ambulance arrives, she is given dextrose (a sugar) intravenously. How did the excess insulin cause her symptoms? How did the glucagon injection and the intravenous sugar help reverse them?arrow_forward
- A male patient was admitted to hospital because his extremities were cyanotic (blue in colour) and he had some convulsions. His blood sugar levels indicated that he was hypoglycemic. The doctors initially gave him glucose intravenously as well as adding it to his diet, but his blood sugar level did not stabilize. However, when the doctors introduced glucagon, the blood sugar levels stabilized. The patient was diagnosed as having a deficiency in glucagon. Select the item below that describes an effect of this condition. Select one: a. The liver breaks down glycogen to glucose, increasing the blood glucose concentration. b. The liver cannot break down glycogen to glucose, so the blood glucose remains low. c. The adipose tissue breaks down fat to form glycogen, keeping blood glucose low. d. The muscle cells cannot store glycogen, so the blood glucose remains high.arrow_forwardIn patients with type 2 diabetes, cells no longer respond to the hormone insulin. What change has likely occurred in these cells to make them insulin resistant?arrow_forwardElaine’s nurse explains that her follow-up appointment will include a fasting blood glucose test. Why is it important to fast before her blood draw? How does this help diagnose diabetes?arrow_forward
- Why would a cause of hyperinsulinism be hypoglycemia? Don’t lower levels of blood glucose inhibit of insulin rather than produce large amounts of it to result in hyperinsulinism?arrow_forwardFor our patient John with diabetes type II, he can make insulin but his body cells can be resistant to this insulin. Note: activated insulin receptors will activate glucose receptors. How is John’s diabetes related to the endocrine system?arrow_forwardAnn is a 64-year-old diabetic who recently experienced the death of her mother. Now she is caring for her father, who is demanding and becoming confused. To complicate matters, Ann must care for her own teenage children and is working full time. For several weeks, Ann has noticed an increase in her blood sugar levels when she tests her late afternoon glucose. Explain why this is happening to Ann.arrow_forward
