Can diabetes cause vasovagal syncope?

Background: vaso vagal syncope and its recurrences may be due to alterations in autonomic system function, that may be more frequent in diabetics. Heart rate variability (HRV) is a valid test to study sympathetic and vaso vagal tone dysfunction.

What causes Vasodepressor syncope?

Summary. Vasovagal syncope is caused by a sudden drop in blood pressure, often triggered by a reaction to something. This causes your heart to slow down for a short time. As a result, your brain may not get enough oxygen-rich blood, which causes you to pass out.

Does syncope affect blood sugar?

One consistent finding was the low blood sugar level in all patients during syncope, as compared with the level 1 hour after recovery. Hypoglycemia can be induced by parasympathetic activation; this may be the product of reflex conditioning.

Is syncope a disability?

Fainting, or syncope, can be serious if it continues to occur. As such, it is a condition that can qualify you for disability benefits. If you suffer from syncope to the extent that you have limited ability and cannot work, then you can be eligible for social security disability benefits.

What to do if a diabetic feels dizzy?

Individuals with diabetes and their families need to recognize the symptoms of hypoglycemia, including dizziness, sweating, confusion, and potentially, coma. Immediate treatment is necessary. Give sugar-containing foods by mouth if the person is awake, or a glucagon injection may save the patient’s life.

Why does the vasodepressor syncope cause bradycardia?

Vasodepressor syncope is caused a reflex of the involuntary nervous system called the vasovagal reaction. The vasovagal reaction leads the heart to slow down (bradycardia) and, at the same time, it leads the nerves to the blood vessels in the legs to permit those vessels to dilate (widen).

What causes temporary loss of consciousness in vasodepressors?

Vasodepressor syncope: The temporary loss of consciousness in a particular kind of situation. (Syncope is temporary loss of consciousness or, in plain English, fainting ). The situations that trigger this reaction are diverse and include having blood drawn, straining while urinating or defecating or coughing.

What happens to the heart during vasovagal syncope?

The vasovagal reaction leads the heart to slow down (bradycardia) and, at the same time, it leads the nerves to the blood vessels in the legs to permit those vessels to dilate (widen). The result is that the heart puts out less blood, the blood pressure drops, and what blood is circulating tends to go into the legs rather than to the head.

What happens when blood pressure drops in vasodepressor?

The result is that the heart puts out less blood, the blood pressure drops, and what blood is circulating tends to go into the legs rather than to the head. The brain is deprived of oxygen and the fainting episode occurs.
