Chapter 31 Lesson 3Diabetes • Chronic Disease that affects the way body cells convert food into energy • 4th leading cause of death by disease in the U.S. • Each day about 1,700 new cases are diagnosed • Can lead to blindness, kidney disease, nerve disease, amputations, and heart disease, and stroke
What Causes diabetes? • In normal digestive process carbohydrates are changed to sugar glucose, then absorbed into the blood and delivered to body cells. • Insulin is an essential link in that process
What Causes diabetes? • In the case of Diabetes sufficient insulin is not produced or is not used efficiently • When glucose is unable to enter the cells, it accumulates in the blood until the kidneys filter out some of the surplus, which is passed off in urine • High sugar content in urine and blood is one of the signs of diabetes
R p • With diabetes sufficient insulin is not produced or is not used sufficiently • Glucose is unable to enter the cells, it accumulates in the blood until the kidneys filter out some of the surplus gluscose • The extra glucose which is passed off in urine and in the blood is one of the surest signs that a person has diabetes
TWO TYPES OF DIABETES • TYPE 1 • TYPE 2
TYPE 1 DIABETES • Formerly known as insulin dependant • Accounts for about 10 % of all cases • Appears abruptly and progresses rapidly • Mostly caused by malfunction of the immune system • Immune system attacks insulin producing cells of the pancreas
Symptoms of type 1 Diabetes • Frequent urination • Abnormal thirst • Unusual hunger • Weight loss • Weakness • Fatigue • Irritability
Type 2 Diabetes • Formerly known as non-insulin dependant • Metabolic disorder resulting from the body’s inability to make enough or properly use insulin • Pancreas produces some insulin but cells cannot use the insulin effectively • 80% of all type 2 diabetics are overweight at time of diagnosis • Usually can be controlled by diet and exercise
Symptoms of type 2 Diabetes • Excess weight • Drowsiness • Blurred vision, • Tingling or numbness in the hands and feet • Slower than normal healing of cuts and bruises • Kidney and bladder infections • 15.3 million have disease and Half do not know it
Arthritis • Inflammation of a joint • 40 million have severe enough for medical attention • Most common types: • Rheumatoid • Osteoarthritis
Rheumatoid • Most serious type • Effects joints of hand and arms, hips, feet and legs • Attacks connective tissue causing fever, fatigue and swollen lymph glands • Causes joints to stiffen and swell • No cure- can cripple
Osteoarthritis • Most common type of arthritis • Affects 16 million people • Results from wear and tear on the joints • Cartilage becomes worn or pitted or completely removed • NO cure for arthritis • Treatment includes exercise, weight control, eating right
