Diabetes mellitus (DM) is a chronic metabolic disease, in which the body cannot properly control blood sugar levels. The body normally regulates sugar levels very precisely with the hormone insulin. People with diabetes do not produce insulin themselves anymore, or their body does not respond to the insulin. The consequences are large and sometimes even life-threatening.


Cause

The blood sugar level (blood glucose) is a measure of the amount of sugar (glucose), which is dissolved in the blood. Insulin lowers blood sugar level and is produced in the pancreas. There are various types of diabetes. The most common are type 1 and type 2 diabetes.

In people with type 1 diabetes, an autoimmune disease, the pancreas doesn’t produce insulin by itself anymore. The immune system destroys the cells that produce insulin. Risk factors for the development of type 1 diabetes are hardly known yet, but likely viruses, environmental factors and food intolerance play a role. Heredity plays a very limited role.

In people with type 2, the pancreas produces too little insulin or the insulin cannot do its job. Risk factors for developing type 2 diabetes are genetic predisposition, overweight, bad fat distribution, lack of physical activity, smoking and unhealthy diet. Especially people who eat too much saturated fat and too little unsaturated fat and food fiber, run a higher risk of type 2 diabetes. The increase in the number of people with type 2 diabetes is mainly caused by overweight. Type 2 is increasingly becoming a lifestyle disease.

Some women develop gestational diabetes from week 24 of pregnancy, but immediately after childbirth it’s over again.


Symptoms

People with diabetes generally experience the following signs and symptoms:

People with type 1 diabetes, who are not getting treatment yet, often feel ill. When blood glucose is really very high, it can cause fainting or even coma. People with type 1 diabetes suffer from weight loss without reason, are very hungry or just not at all and are nauseous or have to vomit.

Type 2 diabetes begins so slowly that it's hardly noticable. Many symptoms are so vague that people don’t go to the general practitioner. So it may happen that a person walks around for years with diabetes without knowing it. Type 2 diabetes can often be identified by one or more of these symptoms: poor healing of wounds, shortness of breath, pain in the legs when walking and infections that often recur, such as bladder infection.


Diagnosis

The general practitioner can confirm the diagnosis of diabetes fairly quickly by taking a drop of blood from the finger. With the aid of a blood glucose meter, the doctor determines the level of blood sugar. When there is doubt, the blood is tested in a laboratory.


Treatment

Diabetes does not pass, but can fortunately be treated properly. The treatment of diabetes is aimed at regulating the blood glucose. In practice, this treatment will be needed life-long. The type of treatment depends on the type of diabetes. Type 1 diabetes is treated with insulin injections and type 2 diabetes usually only with antidiabetic drugs. A combination of medications, insulin and adjustment of lifestyle also occurs.

People can do a lot themselves in the treatment of diabetes. If one learns to control and regulate the blood sugar, the symptoms subside. Regular contact with the practitioner can help. In the treatment of type 2 diabetes, weight reduction is a major focus. Whoever loses weight, might not need to use drugs anymore.


Prognosis

For now, diabetes can only be treated and not be cured. Diabetes can lead to all kinds of complications, for example problems with the feet, decreased kidney function, damaged nerves, eye problems and increased susceptibility to infection. In addition, a person with diabetes can get a hypoglycemia (hypo) or hyperglycemia (hyper). A hypo is a sharp drop in blood sugar and a hyper is just a surge. It’s important that the environment of the patient is aware of this and can recognize the symptoms. When a hyper lasts very long, or when a hypo is severe, it may lead to coma.


Considerations

In a large number of cases, type 2 diabetes can be prevented or postponed by living a healthy life:
