No: Highly unlikely, hard to picture such a scenario, but definitely not the way HIV is transmitted.

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.

Bladder infection: Foul-smelling urine can come from a bladder infection or even from certain foods that we eat. Stds do not usually effect the bladder and i wouldn't think they are responsible for the foul-smelling urine. More than likely it is from a bladder infection. Vaginal infections can sometimes have an odor as well and may be difficult to distinguish from odor caused by urine.

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

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.
