What is it?
Also called diabetes fatty or mature, non-insulin-dependent diabetes (NIDDM) is a metabolic disorder characterized by chronic excess of sugar in the blood (hyperglycemia).
The regulation of sugar (glucose) in the body involves:
Intakes of sugar (essentially a food);
The manufacture ‘internal’ sugar (mainly by the liver);
The peripheral use of sugar at the level of cells: insulin, a hormone produced by the pancreas, then allows the cells to capture and use glucose.
There are a misregulation of this system, with most often a State of insulin resistance in T2DM,: to maintain a constant sugar level, the body needs more insulin, because it becomes less effective. Eventually, even large amounts of insulin are no longer sufficient to use the circulating glucose accumulates in the blood: this is hyperglycemia. Finally, the pancreas gets tired of this permanent stimulation and can no longer produce enough insulin: it is the insulin-necessitance. These mechanisms of insulin resistance and necessitance are particularly those overweight.
Causes and risk factors
T2DM is a very common disease that affects more than a million and a half people in France, and continues to grow. It represents approximately 85% of all diabetes, and concerns both men and women.
The diagnosis of NIDDM is usually around 40-50 years, but the age of onset is earlier.
There is not a single causal factor of the disease but several risk factors:
Genetics and heredity: hereditary factor is very often found (“several members of the family have diabetes”). In addition, certain populations are particularly affected by T2DM confirming its genetic origin;
Overweight and obesity: between 60 and 90% of patients with a NIDDM have important overweight;
It is worth noting that specific causes of diabetes can sometimes be found: living with inflammatory pancreatic (alcohol, overload or malnutrition… diseases), pancreatic, liver disease, endocrine… In these cases, one speaks of secondary diabetes, and not of NIDDM.
All these risk factors must motivate a regular enhanced surveillance: diabetes in the family history, obesity, diabetes in pregnancy, birth of babies being more than 4 kilos, taken certain medications…
What is it?
It is localized aortic dilation.
The aneurysm may sit on one of the five segments of the aorta:
-The thoracic aorta: bottom-up part, horizontal portion, top-down portion;
-The sus-renal abdominal aorta (above the start of the renal arteries);
–Abdominal aortic aneurysm sous-renale (at the bottom of the departure of the renal arteries).
-Men are much more affected than women.
-Abdominal aortic aneurysm button 6 to 7% of the general population.
Causes and risk factors
Atherosclerosis is the main cause. Syphilis often causes of aneurysms of the thoracic aorta. Other causes (thoracic trauma, infective endocarditis, sepsis, elastic fabric, polyarteritis nodosa… disease) are more rare.
Spontaneous evolution is dominated by the risk of rupture often heralded by the appearance of painful signs in the territory of the aneurysm. If broken, death is immediate.The probability of failure is greater for large aneurysms (more than 6 cm in diameter). Continue reading “The aortic aneurysm”
Diabetes is a metabolic disorder characterized by an excess of sugar in the blood. In France, more than three million people are supported for this disease, or 4.6% of the population. While their number is constantly increasing (+ 5.4% per year between 2000 and 2011), a diabetic on six would not be diagnosed.
The most common diabetes is type 2 diabetes which affects 90% of diabetics and usually occurs in overweight more than 50 years. Conversely, the type 1 diabetes appears rather in children, in whom it causes weight loss. Pr Jean-François Gautier, endocrinologist-diabetologist, precise symptoms and risk factors related to each of these two types.
Type 1 or type 2, diabetes is an excess of sugar in the blood
Diabetes is related to insufficient or improper use ofinsulin, a hormone that helps glucose (sugar) to enter the cells. That it remains so in the blood in excessive amounts, it is hyperglycemia. In France, more than three million people are treated for diabetes. Continue reading “Diabetes, know the symptoms and risk factors”
Stroke is a medical emergency. Quickly, the doctor must be able to determine whether it is an interruption of blood flow or bleeding and if the affected brain tissue is recoverable or permanently destroyed. Other tests are needed to determine the cause of the stroke.
The nature, severity of symptoms, the patient’s history, its risk factors, age are the first elements of diagnosis. The doctor should also quickly determine:
If this is ischemic (obstruction of a blood vessel by a clot, which reduces the blood flow in a brain area); Hemorrhagic accident (also known as cerebral haemorrhage or cerebral hematoma) following the rupture of a cerebral vessel. In this case, the blood spreads and damages the brain tissue around; Continue reading “What tests for what diagnosis?”
Phlebitis and embolism are both severe and relatively common but little-known conditions. The origin of these phenomena: thrombosis, a blood clot blocking an artery. How such accidents occur? Can we reduce the risk? The point with Doctissimo.
When blood clots form in a vein, the support is easy. On the other hand, when it comes to a deep vein (phlebitis), there is urgency. The clot (called thrombus) risk standing out, cause abrupt obliteration of a blood vessel, it is the most often pulmonary embolism. Hence the importance of carefully to know the risk factors for this disease.
If you have a deep pain in a calf, accentuated when you raise your foot must be think of phlebitis. A quick reference to your attending doctor, followed if necessary an ultrasound will depart (or confirm) the hypothesis. Continue reading “Phlebitis, thrombosis, embolism: what are your risks?”
