Our body forms from billions of cells. To create energy, the cells need energy in single units known as glucose.

When we consume something, it breaks down into a simple carbohydrate form known as glucose. Glucose gives the energy to our body required daily to perform activities of daily life.

Diabetes mellitus

Diabetes mellitus Blood Sugar Levels

A chronic disease that interlinks with Diabetes mellitus is a disease in which the blood sugar level rises up high.

After having a diet in a great amount, the food will convert carbohydrates into high levels of sugar and it results in severe health issues in the body of a person.

Veggie causing Diabetes

Sugar isn’t capable of transferring itself into the cells. The pancreas organ of our body produces insulin into the blood, and then blood helps as a “key,” to transfer sugar into each and every cell to create and utilize energy.

The blood and blood vessels are the pathways which help to transfer sugar from where it forms (i.e. stomach) or where it is manufacturing (i.e. in the liver) to the cells of our body (i.e. where our body uses i.e. muscles) or where it stores (i.e. fat tissues).

When sugar enters the bloodstreams into the cells of our body, the level of blood sugar minimizes.

Without the presence of insulin, or the help of bloodstreams sugar can not enter in any cell of our body to utilize as energy, This leads to a rise in sugar level.

The condition in which the blood sugar level rises will lead to high blood sugar or hyperglycemia.

Diabetes impacts how the body of a person uses blood glucose.

Glucose is essential for the health of people because it’s a significant resource of energy for the cells of the body which creates our body’s muscles and tissues of our body.

It’s the main source of energy for the brain too. Glucose produces in our body from:

  • Diet
  • Liver

Blood streams consume sugar and after its transfer into the cells of our body, with the help of insulin.

And then the liver stores glucose in a complex form of glucose known as ‘glycogen’ and creates glucose.

When the body lowers the blood sugar levels, for example, people are not eating food for a while, the liver of their body catabolizes (breaks down) the complex form glycogen into simple form glucose to balance the blood glucose levels in a normal range.

Diabetes happens because of these mechanisms:

  • The body produces an insufficient amount of insulin hormone with the help of the pancreas gland and helps to lower blood sugars- Depend on insulin- type 1
  • Insufficient sensitivity of cells after the action of insulin on the body- Do not depend on insulin-type 2 diabetes.

People with diabetes disease have to remember this essential information about the values of the blood sugar in the target range because it will help to regulate the blood sugar level after consuming the nutrient-rich diet. People often need to check their blood sugar levels a few times a day.

The health care personnel will perform a blood test called A1C to check that the blood sugar level is in balance or low or high for better precautions.

Diabetes helps to prevent the body of a person from consuming energy from the diet properly either the reason the body can not produce insulin in adequate amounts or the body can not use the insulin or react on the production of insulin correctly.

Signs and symptoms

  • The first symptom occurs in diabetes that relates to high blood sugar levels, and loss of sugar monomers(glucose) while urination.
  • Great amounts of glucose while urination can result in more urine output and sudden urination and results in the condition of dehydration.
  • The dehydration may increase thirst and urges to drink more water.
  • The relative insulin inadequacy results in a weight loss of the body.

  • Fatigue
  • Nausea
  • Vomiting

Although if you have this type of diabetes you probably have a chance to recognize it in later life too.

This type of diabetes mellitus is known as Gestational Diabetes.

Functioning and the production of insulin in the pancreas.

The alterations of glucose in the blood and the hormone responsible for the lowering of sugar (Insulin-Pancreas) in humans during the normal diet of a day with three meals.

Beta cells present in our pancreas are responsible for the normal release and the functioning of insulin hormone.

Production of this hormone in the pancreas is fickle steady through the cells.

Its production and functioning are activated by the means of a human only. Predominantly, the food which contains high glucose substances.
