Does Low Blood Sugar Cause Weight gain or Loss?

Is there a link between changes of blood sugar and weight changes (either weight loss or gain)? Having normal blood sugar can be one of signals that your body has a normal mechanism of glucose metabolism. In people with diabetes, their blood glucose is relatively easier to extremely fluctuate either too high (hyperglycemia) or too low (hypoglycemia).

The role of glucose in affecting your weight

As well we know, the body gets energy from a substance called glucose (it is a simple form of sugar).

Your body also can get the energy supply from protein and fat, but in general glucose taken from food has much more contribution for energy supply of your body.

Furthermore, the body also can get glucose from glycogen stored in the liver when the blood glucose is low.

The use of glycogen stored in the liver for energy is typically for the reserve energy of your body. For instance, when you run to pursue a bus school in the morning but you haven’t eaten (skipping your breakfast), your body can use glycogen for energy.

Glucose taken from foods can be directly absorbed and then go into the bloodstream. In the bloodstream, glucose then will be distributed to many cells around the body. Cells of the body need energy to keep functioning and to support our activity throughout the day.

To make sure that glucose in the bloodstream can be optimally absorbed by cells and muscles, your body needs a kind hormone called ‘insulin’ that produced by pancreas.

Without this hormone, the mechanism of glucose metabolism can be affected. Therefore, people with insulin resistance (such as in diabetics) are relatively easier to have high blood sugar.

Once glucose was absorbed by cells and muscles, it then can be converted to become energy. And for the excess absorption can be stored as cells of fat or stored as glycogen in the liver as written before.

Both glycogen and fat can be converted into energy when your body needs. They can be used for energy when the brain sends signal that your body needs more energy, such as during exercise.

Does low blood sugar cause weight gain or weight loss?

In general, the level of blood glucose is relatively lower during and after fasting. It usually increases during and after eating.

Low blood glucose is more often associated with weight loss instead of weight gain. However theoretically, it may also cause weight gain – but not directly!

When the amount of glucose in the bloodstream is too low, converting glycogen stored in the liver may be not enough to restore the balance of blood glucose. As a result, you may feel sweetening, weakness, and fatigue due to lack of energy.

There is nothing wrong with this opinion, but the truth is most of the initial weight loss comes from the decreased body’s water supply and muscles. Most people with hypoglycemia experience excessive sweating! See also some common symptoms of hypoglycemia!

At short time of being hypoglycemia, your weight loss doesn’t come from the fat metabolism. When you have too low blood sugar, your body will respond it by activating starvation and survival mode. But your body will not burn your fat cells at short time.

However, having frequent low blood glucose in long term may help restore your normal weight if you are overweight. But this option is not recommended, because it can be harmful for your health.

Furthermore, if you are non-diabetic, you need to take an extremely weight loss diet or do a strenuous exercise to decrease your blood glucose very low.

How about with the chance of getting weight gain from low blood sugar?
