Phobia therapy: is highly effective. This is likely to respond to the same sort of treatment. Without an actual examination, I cannot give specific medical advice on your particular health, a variation of cognitive behavioral therapy called applied tension is generally used http://www.anxietybc.com/self-help/applied-tension-technique-people-who-faint-sight-blood-or-needles

Vasovagal response : You are not alone. Many people who became doctors have fainted at the first sight of blood. Fear of the unknown, overwhelmed by all the stimulation, lack of sleep, and hunger can create the perfect storm and lead to a vasovagal response. As you become more comfortable and through repetition (habituation) this queasiness will resolve.

With fingersticks: If the hands and fingers aren't clean and dry, home blood sugar readings may be inaccurate. Sugar on the fingers could end up falsely elevating blood sugar. A concomitant venous sample in lab could demonstrate a discrepancy. Also, the meter may be inaccurate. Eating before a fasting blood sugar may raise the blood sugar in someone with diabetes because it would not be fasting anymore.

Very possible.: This symptom can be associated with disorders of the heart, like aortic stenosis, as well as anything that involves the cns, like a tumor. In fact, some telltale signs/syx. Include focal neurological deficit (impaired judgement, etc.), seizures, headache, stroke-like symptoms which may mean brain hemorrhage. Vision changes can occur due to the growth of a tumor. See your doctor to be sure.

A 55-year-old female asked:

Can l-arginine lower blood pressure & if so what is recommended dosage?

1 doctor answer1 doctor weighed in
Dr. Ralph Morgan Lewis
Family Medicine 38 years experience
Possibly beneficial: In some people. Arginine is converted to nitric oxide, which has a relaxing effect on blood vessels & can thus reduce blood pressure somewhat. No standardized dose has been recommended. Be advised that arginine can also trigger or worsen viral infections like herpes. Discuss this supplement with your doc before taking it.
