Exercise can cause hypoglycemia
I have never caused hypoglycemia by exercise. But some diabetic patients cause hypoglycemia due to intense exercise.
Sometimes sudden hypoglycemia happnes at midnight when more than 10 hours have passed since exercise in the day.
Hypoglycemia occurs at bedtime, it is more dangerous than when waking up in the daytime! The reason is that if you get hypoglycemic at bedtime, fatal arrhythmia tends to occur and you may die as it is.
If sugars called glycogen stored in the muscle are rapidly depleted, there is a possibility that hypoglycemia may occur without replenishment in time.
In the case of adult men, glycogen is stored in the muscle about 300 g · About 100 g in the liver.
I think that there are few common people who exercise to exhaust up the glycogen in the body all at once！
When diabetic patients are using insulin injection or oral hypoglycemic drugs, it is easy for hypoglycemia to occur when exercising hard at the time of high insulin sensitivity (evening in my case).
If you have normal gluconeogenesis that does not use insulin injection or taking medicine, you don’t cause hypoglycemic after exercise …Even if you are doing a stoic low carb diet.
Does it become hypoglycemic without using medicine or insulin?
In most cases, only those who use diabetes medicine or insulin will cause hypoglycemia.
But the possibility that diabetic patients who don’t use diabetes medicine or insulin may cause hypoglycemia is not 0.
In the early stages of borderline diabetes and type 2 diabetes, the insulin secretory capacity remains.
In type 2 diabetes, the timing of insulin addition secretion is delayed. When eating a large amount of carbohydrates and doing exercise, the blood sugar level falls too much later due to the exercise effect and delayed supplementation of insulin.
According to Dr.Kouji Ebe(famous Japanese physician familiar with low carbohydrate diet), patterns such as “functional hypoglycemia + border type diabetes” or “functional hypoglycemia + diabetes” are not uncommon.
If you become severely diabetic like me, insulin does not even “get out too” after a meal…
After eating a lot of carbohydrates, Even if you exercise you can’t know whether your blood sugar level will be normal.
Hypoglycemia is more dangerous than hyperglycemia
Injection of insulin may cause hypoglycemia due to excessive injection. And People who have mild type 2 diabetes and have a large amount of insulin delayed may also cause hypoglycemia.
Diabetic patients often suffer from high blood glucose levels, but hypoglycemia is more dangerous than hyperglycemia in the sense that they may be involved immediately in life.
If you are using insulin injection or oral hypoglycemic drugs, please be especially careful for low blood sugar at night！
For dinner that contains a large amount of carbohydrates and lipids, blood glucose may not rise so much about 2 hours after meals, but there is a possibility that the blood sugar level may unexpectedly rise and fall in the middle of the night.
Because large amounts of lipids delay digestion and absorption. Many Japanese diabetic patients believe that “If you eat sugar with lipid, your blood sugar level will not rise so there is nothing wrong.”
Due to the high carbohydrate diet, the blood sugar level rises or falls too much. Especially at night it is dangerous, so be careful.
