I usually experience Vaso Vagal reaction after having blood drawn. My latest reaction was flu-like symptoms. Should I do more research into this?

I usually experience Vaso Vagal reaction after having blood drawn. My latest reaction was flu-like symptoms. Should I do more research into this?

Tell phlebotomist: Such a reaction is not uncommon and is not a disease. Next time you need to have blood drawn, tell the person drawing blood that you tend to faint. After having your blood drawn, rest in the chair for 5-10 minutes. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex.

Near-syncope: It sounds like defecation syncope or near-syncope, which is a variation of vaso-vagal syncope. You should make an appt with your primary care doctor for evaluation. You can go to local ER for evaluation for more immediate attention also.

What is a vagal surge?

What is a vagal surge?

Increased vagal act: When the vagus nerve is stimulated, it is called vagal surge, the response is often a reduction in heart-rate or breathing. In some cases, excessive stimulation can cause someone to have what is known as a vaso-vagal response, appearing to fall into a faint or coma because his or her heart rate and blood pressure drop so much.

What is a high vagal tone?

What is a high vagal tone?

Prone to relax: High vagal tone refers to ease of excitement of the parasympathetic branch of autonomic nervous system, which functions to maintain homeostasis, decrease anxiousness, slow heart, ameliorate digestion ; elimination, ; effect ejaculation ; orgasm, i.e., pleasure functions. Other branch, sympathetic, operant w. Fight ; flight for survival. Excess vagal tone can predispose to syncope (fainting).

Due to a benign 2x4cm growth on the right vagal nerve, the nerve had to be cut. What does this now mean for the patient?

Vagotomy: Benign tumors of the vagus nerve are extremely rare. The location of the tumor determines the impact on cutting of the vagus nerve. Discuss with the surgeon who removed the tumor to assess the impact on the patient.

When your vagus: Nerve gets stimulated (usually by pain, but it could be anything), it sends out signals to slow your heart. If the heart rate slows enough, you can have a fainting spell. This is called a vaso-vagal reaction.

What is the vagal nerve stimulator?

What is the vagal nerve stimulator?

VNS: Is a wonderful device used to treat refractory seizures and depression. About the size of half an Oreo Cookie it is placed under the skin by a skilled surgeon. A thin wire sends a tiny current intermittently to the brain by way of the left Vagus Nerve in the neck. My patients who are lucky enough to have one report overwhelmingly a vast improvement in their lives. They are made in Houston Tx

How to treat a vagal paraganglioma?

Doctors can evaluate: Paraganglioma are slow growing, usually benign tumors which can be found in many different locations.

What is the definition or description of: vagal nerve stimulation?

Electrical pulses: Vagus nerve stimulation prevents seizures by sending small pulses of electrical energy to the brain via the vagus nerve. These pulses are supplied by a device something like a pacemaker commonly implanted under skin in the chest.

Do sinus tach respond to vagal manoeuvres, or only SVTs?

Do sinus tach respond to vagal manoeuvres, or only SVTs?

See below.: With sinus tachy, a vagal maneuver will cause the HR to slow gradually. With release, the HR will gradually return to its original rate. With SVT, vagal stimulation will not slow the HR unless is suddenly breaks to normal rhythm. The rate then suddenly drops from, say 170, to

Do you treat vagal afib differently?

How do you diagnose and treat vagal nerve damage.

How do you diagnose and treat vagal nerve damage.

Complicated answer: I would need more info as the diagnosis falls into 2 categories- one when the nerve is overactive (vasovagal syncope) or underactive (bowel stasis- gastroparesis). In my experience the overactive form is more common in the younger patient and the underactive form is more common in older individuals and particularly those with diabetes. Please meet with your doctor to discuss. Well wishes.

Can vagal paragangliomas ve detected by ultrasound?

Can vagal paragangliomas ve detected by ultrasound?

Perhaps: The vagus nerve carries autonomic information to the heart and bowels. It travels from the brainstem (cranial nerve 10), along structures in the neck, then along large blood vessels to the organs of the body. The parasympathetic ganglia can involve vagal nerve fibers at different locations deep in the body. If there is overgrowth of these ganglia, there can develop a ganglionoma.
