Diabetes Mellitus

•This is a disorder of carbohydrate metabolism in which the ability to oxidize and utilize carbohydrates is lost as a result of disturbances in the normal mechanism

Page 38: Chap2 carbohydrates

The disorder is characterized by:

• Elevated blood sugar (hyperglycemia) Polyuria-excessive urination Polydipsia-increased thirst Polyphagia-increased appetite

• Involuntary weight loss• Visual disturbances

(retinopathy/osmotic lens shape changes)

• Candidal pharyngitis/vaginitis• Acute ketotic illness

Testing :

Fasting Plasma Glucose Test

(FPG) - (cheap, fast)

*fasting B.G.L. 100-125 mg/dl signals pre-diabetes

*>126 mg/dl signals diabetes

Oral Glucose Tolerance Test

(OGTT)

*tested for 2 hrs after glucose-

rich drink

*140-199 mg/dl signals pre-

diabetes

*>200 mg/dl signals diabetes

80 to 90 mg per 100 ml, is the normal fasting blood glucose concentration in humans and most mammals which is associated with very low levels of insulin secretion.

Management of DM

•Diet

•Oral Hypoglycemic Agents

•Insulin

Page 43: Chap2 carbohydrates

Diet • Cornerstone of diabetic therapy• Individualized, tailored to the needs

of the patient• The goal is proper growth and

development (for the young diabetics) and normalization of weight in the normal work or school setting without hyperglycemia or hypoglycemia

Page 44: Chap2 carbohydrates

Oral Hypoglycemic Agents

• The oral agents sulfonylureas and arysylfonylureas are indicated for Type II DM patients

• Side effects include: toxic reactions Nausea, vomiting, Dyspnea, Palpitations

Page 45: Chap2 carbohydrates

Insulin • Indicated (together with dietary

manipulation as the primary mode of metabolic control for: Newly diagnosed Type I diabetics Type II diabetics failing to maintain

adequate glycemic control on oral hypoglycemic medications

Preoperatively Drug pregnancy

Page 46: Chap2 carbohydrates

Dental Correlations• Generally accepted that there is a

direct relationship between DM and dental diseases

• Symptoms can be related to salivary and dental changes, periodontal and mucosal abnormalities, opportunistic infections, acetone or diabetic breath and altered wound healing

Page 47: Chap2 carbohydrates

Dental Management• Obtain a comprehensive medical history from

the known or suspected diabetic patient• Establish the severity and degree of control

before instituting any dental management When the patient’s diabetes is well controlled and

there are no concurrent medical problems, he may receive appropriate dental therapy without modification of accepted dental protocols

When the patient’s diabetes is uncontrolled, or when there is a serious underlying organic disease, elective care or surgical procedure should be delayed until blood glucose level has been regulated

Page 48: Chap2 carbohydrates

When the severity of diabetics or the degree of control is not known, treatment should be limited to palliation

• In the dental treatment of all diabetics, reduce pain as much as possible. The stress stimulates the release of epinephrine, which in turn, increases the blood glucose level

• Be careful with antimicrobial therapy, excessive use of unnecessary antibiotics can lead to oral or systemic fungal infections

Page 49: Chap2 carbohydrates

Lactose intolerance

Page 50: Chap2 carbohydrates

Overview

Lactose intolerance is the inability to digest lactose (a type of sugar found in milk and other dairy products).

Page 51: Chap2 carbohydrates

Symptoms

*Abdominal bloating& Abdominal cramps

*Diarrhea

*Floating stools & Foul-smelling stools

*Gas (flatulence)

*Malnutrition

*Nausea*Slow growth

*Weight loss

Page 52: Chap2 carbohydrates

Causes

Lactose intolerance happens when the small intestine does not make enough of the enzyme lactase. Babies' bodies make this enzyme so they can digest milk, including breast milk. Beforehumans became dairy farmers, most people did not continue to drink milk, so their bodies did not make lactase after early childhood. Lactose intolerance is more common in Asian, African, African-American, Native American, and Mediterranean populations than it is among northern and western Approximately 30 million American adults have some amount of lactose intolerance by age Not having enough lactase (lactase deficiency) may also occur as a result of intestinal diseases such as celiac sprue and gastroenteritis, or after bowel surgery. Temporary lactase deficiency can result from viral and bacterial infections, especially in children, when the cells lining the intestine are injured.

Page 53: Chap2 carbohydrates

Tests & diagnosis

*Enteroscopy

*Lactose-hydrogen breath test

*Lactose tolerance test

*Test for stool-reducing substances

Page 54: Chap2 carbohydrates

Prevention

There is no known way to prevent lactose intolerance. If you have the condition, avoiding or restricting the amount of milk products in your diet can reduce or prevent symptoms.

Page 55: Chap2 carbohydrates

Treatment

*Buttermilk and cheeses (they have less lactose than milk

*Fermented milk products, such as yogurt

*Goat's milk (but drink it with meals, and make sure it is supplemented with essential amino acids and vitamins if you give it to children)

*Ice cream, milkshakes, and aged or hard cheeses

*Lactose-free milk and milk products

*Lactase-treated cow's milk for older children and adults*Soy formulas for infants younger than 2 years

*Soy or rice milk for toddlers

*Take calcium supplements

*Eat foods that have more calcium (leafy greens, oysters, sardines, canned salmon, shrimp, and broccoli)

*Drink orange juice that contains added calcium

Page 56: Chap2 carbohydrates

Complications

Weight loss and malnutrition are possible complications.
