Re: Type II Diabetes - now on insulin
The current dietary advice for those with type 2 diabetes is to maintain a healthy, balanced diet, limiting simple carbohydrates. We no longer tell patients that they can't have any "sugar." Eliminating carb containing beverages such as soda and fruit juices is important. All forms of carbohydrate, simple or complex, raise blood glucose levels. Carbs are important for growth, development, and proper metabolism, so they are not eliminated altogether. We do encourage healthy, complex carbs such as whole grains, beans/legumes,low-fat dairy, and whole fruits while limiting simple carbs. Portion control is a very important aspect of dietary advice for those with type 2 diabetes, especially when indulging in a treat.
As far as the insulin goes...you most often see a basal/bolus regimen. This means a long acting insulin given once daily (Lantus or Levemir) and a rapid acting insulin given with meals/snacks (Humalog, Novolog, Apidra). The rapid insulins are dosed using an insulin to carb ratio, so the dose varies with the carb content of the meal. For example, if the meal contains 60 grams of carb, if the ratio is 1 unit for 15 grams, the dose is 4 units. If the ratio is 1 unit for 10 grams, the dose is 6 units. The ratio is determined by comparing a pre-meal blood glucose level with a 2 hour post meal blood glucose level. The goal is to get the post meal level to be (usually) within 30-50 points of the premeal level. If a patient is eating "at will" between meals, it is difficult to accurately assess the action of the premeal insulin.
The fasting glucose level in the morning determines how well the long acting insulin has been dosed.
It is important to remember that it is carbohydrate in general, not just "chocolate and cookies" that are raising blood glucose. So the patient shouldn't be eating any carbs between meals while determining the dose, be it candy, bread, mashed potatoes, cereal, etc.
The length of the hospitalization will vary according to the patient, and often hospitalization isn't required. The reason is that in the hospital their food, activity levels, etc., are different than they are at home, and the dose may change again as soon as they assume their usual routines at home. Weight loss and activity greatly affect insulin sensitivity in those with type 2 diabetes, so the ratios and long acting insulin doses may very well change as children grow, change weight, change activities, etc.
Hope that helps!
