Diet.
Oral hypoglycemic agents or insulin
(indications for each vary with the type of
DM and severity of the disease).
Exercise program.
Phytotherapy (plant’s therapy).
Nontraditional methods of treatment.
Education
The main principles of diet
The main principles of diet.
Normal-calorie diet in patients with type I DM
(35-50 kcal/kg of ideal weight (weight =
height – 100)) and low-calorie diet in obese
persons (mostly in patients with type II DM
(20 – 25 kcal/kg of ideal weight)). We try to
decrease weight in obese patients on 1-2
kg/month by such diet.
•
The main principles of diet.
Regimen has to be consist of 4 – 5 – 6 small
feedings a day.
(The most frequent regimen consists of 4 feedings a
day, in which:
- breakfast comprises 30 % of total calories,
- dinner – 40 %,
- lunch – 10 %,
- supper – 20 %.
Sometimes patients need second breakfast (when they
have a tendency to develop hypoglycemia). In such
case it comprises15 % of the total calories and we
decrease the quantity of calories of the first
breakfast and dinner).
• Exclusion of high-calorie carbohydrates (sugar,
biscuits, white bread, alcohol).
The main principles of diet.
•
Increasing the quantity of high fiber-containing foods
(fruits (exclusion: banana, grapes), vegetables,
cereal grains, whole grain flours, bran. Patients need
40 g fibers per day
•
Limiting of meat fat, butter, margarine in diet,
decrease red and brown meats, increase poultry and
fish, encourage skim milk-based cheeses. Should be
used skim or low-fat milk, not more than 2 – 3 eggs
weekly.
•
Alcohol should be avoided as much as possible
because it constitutes a source of additional calories,
it may worsen hyperglycemia, and it may potentiate
the hypoglycemic effects of insulin and oral
hypoglycemic agents.
Oral hypoglycemic agents.
• Inadequate control of hyperglycemia by the diet
and exercises interventions suggests the need for a
good glucose-lowering agent.
• Oral hypoglycemic agents are useful only in the
chronic management of patients with type II
DM.
• The most commonly used are:
- the sulfanilureas,
- biguanides,
- alpha-glucosidase inhibitors,
- non-sulfanylureas insulin stimulators,
- repaglinides.

Indications for insulin therapy
1. All patients with type I DM.
2. Some patients with type II DM:
• uncontrolled diabetes by diet or oral
hypoglycemic agents;
• ketoacidosis, coma;
• acute and chronic liver and kidneys disease with
decreased function;
• pregnancy and lactation;
• II – IV stages of angiopathy;
• infection diseases;
• acute heart and cerebral diseases;
• surgery.

Exercise program
• Exercise is an excellent adjunct to diet
therapy, but it is very ineffective when
used as the sole weight-reducing modality.
• Exercises must be clearly planned and
depend on patient’s abilities and the
physical condition, exclusion of the
competition’s elements.
Exercise program
• Exercises may be valuable adjunct to the
management of the DM by:
• lowering blood glucose concentration;
• decreasing insulin requirements;
• potentiation the beneficial effects of diet and
other therapy.
• To prevent hypoglycemia, patients should
carefully monitor glucose level and taking of
insulin. Mostly they need to reduce the insulin
dosage by 20 – 25 % on the day that strenuous
exercises is planned.
