How long does rebound hyperglycemia last?

Hyperglycemia due to a Somogyi effect can sometimes persist for as long as 3 days after a single hypoglycemic episode. As a result, blood glucose concentrations do not always normalize within a few days after lowering the insulin dose. Clinical signs: Polyuria, polydipsia.

What causes the Somogyi effect?

The causes of Somogyi phenomenon include excess or ill-timed insulin, missed meals or snacks, and inadvertent insulin administration. Unrecognized posthypoglycemic hyperglycemia can lead to declining metabolic control and hypoglycemic complications.

What is rebound hypoglycemia?

Reactive hypoglycemia (postprandial hypoglycemia) refers to low blood sugar that occurs after a meal — usually within four hours after eating.

Does the Somogyi effect mean you have diabetes?

For people who have diabetes, the Somogyi effect and the dawn phenomenon both cause higher blood sugar levels in the morning. The dawn phenomenon happens naturally, but the Somogyi effect usually happens because of problems with your diabetes management routine.

How is waning insulin treated?

If you have waning insulin, an after-dinner walk or other workout can help keep your blood sugar down overnight. But use caution when exercising before bedtime. The blood sugar-lowering effects of exercise can last for hours, so if you work out before bed, you risk going low overnight.

What is insulin rebound?

A physiological response caused by ingesting too much sugar. Blood glucose levels rise quickly and induce an exaggerated insulin response that overcompensates for the rise, and causes the blood sugar level to fall to a level lower than it was before sugar ingestion.

What is rebound blood sugar?

High blood sugar in the morning may be caused by the Somogyi effect, a condition also called “rebound hyperglycemia.” It also may be caused by dawn phenomenon, which is the end result of a combination of natural body changes.

What causes blood sugar to drop rapidly?

Not eating enough food or skipping meals, taking too much medicine (insulin or pills), exercising more than usual, or taking certain medicines that lower blood sugar can cause your blood sugar to drop rapidly.

How do I get rid of Somogyi effect?

For Somogyi effect:

Decreasing the dose of diabetes medications that are causing overnight lows.
Adding a bedtime snack that includes carbs.
Doing evening exercise earlier.
If you take insulin, switching to an insulin pump and programming it to release less insulin overnight.

How can rebound hyperglycemia be prevented?

Practical ways to avoid Somogyi effect include regular blood glucose monitoring, logging blood glucose values, conservatively increasing insulin, being aware of hypoglycemia and how your insulin influences it, and using the most suitable insulin for your circumstances.
