Question 1

can having excessive amounts of caffeine cause you to fail the visual field test,?

Accepted Answer

No: Caffeine consumption does not interfere with your visual field data. If, however, you are extremely jittery, you may be more nervous and overly responsive with the hand held clicker which may lead to higher percentage of false positives and fixation losses. The latter decreases the reliability of the visual died results.

Question 2

could cardio workouts repair heart damage caused by excessive caffeine/nicotine?

Accepted Answer

Cardio workouts: Cardio work out help to develop collateral circulation.

Question 3

can drinking high quantity of caffeine cause excessive irritability, actions that resemble someone out of control, on edge, manic, hard to reason with?

Accepted Answer

Yes, it can happen: In large quantities, this can indeed happen. For some sensitive folk, less can do it. For very sensitive (allergic) folk, any can.  If this is you, you need to consider reductions in quantity or avoiding it all together. I'd limit my intake to really great coffee in small amounts. It's your choice! good luck.

Question 4

will adderall (dextroamphetamine and racemic amphetamine) cause cravings for caffeine, sugar and excessive shopping?

Accepted Answer

Possibly: Stimulants/amphetamines like Adderall (dextroamphetamine and racemic amphetamine) can have many different side-effects. These include manic behaviors and increases in goal- directed behaviors. I wonder whether the Adderall (dextroamphetamine and racemic amphetamine) is causing a "buzz, " and the person is trying to accentuate those pleasurable feeling, with more pleasure seeking behaviors and actions? All theoretically increase Dopamine levels in the brain. It doesn't seem healthy.

Question 5

can caffeine cause anexity?

Accepted Answer

Hmmm...: What do you mean by anxiety?  In my way of thinking, caffeine (espcially in normal amounts) as a drug does not have the pharmacological property of causing ANXIETY.  However, EXCESS caffeine usage in an individual can, by a different number of ways (i.e. too much as in Energy drinks, withdrawal as in cutting back or sudden cold turkey) cause jitteriness, nervoussness, shakiness, etc.

Question 6

can caffeine cause freckles?

Accepted Answer

No: Freckles are caused by sun exposure.

Question 7

does consuming caffeine cause blurred visions?

Accepted Answer

No: Enjoy your coffee or whatever source of caffeine.  No testing, and there have been many, show an adverse effect of caffeine on the vision or health of the eye.

Question 8

what causes caffeine to take so long to take effect on me?

Accepted Answer

Caffeine metabolism: Caffeine is metabolized by a liver enzyme. If you have a particular common gene mutation what is known as a snp (single nucleotide) polymorphism) you may be a rapid metabolizer of caffeine, which means it gets broken down more quickly generally requiring you to have to take in more before feeling any effect. If you were a slow metabolizer you would feel the effect more quickly and stronger.

Question 9

what causes an unusual sensitivity to caffeine?

Accepted Answer

Unanswerable: Please re-ask this question with the words "unusual sensitivity' explained. This is not a medical diagnosis or term or common condition.

Question 10

why and how exactly caffeine causes "sugar crash" ?

Accepted Answer

All stimulants: work like adrenaline, and increase the body's metabolic rate, so we burn more fuel to ensure that we can meet the "fight or flight" response.  So we burn sugar more rapidly, and the low blood sugar actually further increases adrenaline and related chemicals (like dopamine) leading to a vicious cycle.
