Does caffeine inflame hemorrhoids?
Caffeine is a vasoconstrictor, so it will actually help shrink your hemorrhoids. This can be a great way to help cure your hemorrhoid problem, but it could make it worse if you aren't aware of the side-effects.
Caffeine can also cause small dry stools, which could likely make the problem worse. However, you can resolve this by drinking lots of water and eating lots of fiber. Stool softeners can also help a lot.
How does caffeine increase sodium loss?
Caffeine is a diuretic. It dilates smooth muscle vessels and increases the volume of fluid loss via urine. Along with water loss there will be loss of salts including Na+. I don't think that caffeine has a direct effect on sodium channels (preventing the reabsorption in the distal tubule) so I am assuming that the sodium loss is due to increased fluid loss.
No, Caffeine is not man made. Caffeine is naturally produced by several plants including coffee, guarana, yerba mate, and cacao. Its purpose is to dissuade predators of the plant, however humans are immune to this toxin.

"no it doesn't"
Erm yes it does - that or the UK government has forced me to do a whole compulsory unit on the Nervous System and Caffeine etc.
It's because caffeine is a stimulant.
This stimulant stimulates the synapses - mean messages travel faster along the Central Nervous System.
It also causes blood to pump faster around the body - allow more oxygen to get to muscles speeding up the body's working time in general.
That's all I know...
What are the benefits of being caffeine free?
In most people caffeine is an addictive substance to some degree, although some would describe it as highly addictive.
Depending on a substance to function normally or even stay awake, can become a vicious cycle. It changes our brain's chemistry resulting in the need for more of the substance to achieve the desired results.
Quitting caffeine or coffee breaks the cycle and frees us from needing a daily drug to function normally.
2. Financial SavingsThe cost of a caffeine addiction can add up and thousands of dollars a year could be saved if you quit.
3. Lower Blood PressureCaffeine can raise your blood pressure a few points and even more in some people.1
Quitting coffee or caffeine can lower your blood pressure and keep your heart from working as hard.
4. Better SleepCaffeine can greatly reduce the amount and quality of sleep.2 Drinking coffee or energy drinks too late in the day can interfere with getting to sleep since the half-life of caffeine is 4-6 hours.
Even people who have no caffeine after 12 noon report a better quality of sleep after quitting caffeine.
5. Better MoodCaffeine alters the mood. Many report being grumpy until they've had their morning coffee and others feel lethargic when the caffeine begins to wear off in the afternoon.
Quitting can even out the ups and downs.
6. Decreased AnxietyMany people report that caffeine increases their anxiety levels. This has to do with how caffeine stimulates the adrenal glands.3

8. Convenience- Imagine never having to stop at Starbucks on the way to work?
- Imagine never having to stop by the convenience store for a Red Bull?
- Imagine erasing making coffee from your morning routine?
- Imagine a backpacking trip without packing caffeine pills or the extra weight of coffee making equipment? 9. Fewer Trips to the Bathroom
Caffeinated beverages cause us to urinate more often and in some people even can cause incontinence.
Caffeine also stimulates the smooth muscles of the colon, which cause them to contract.
This can be challenging during meetings, road trips, or when bathrooms aren't convenient.
Quitting can reduce the need to use the bathroom as often, especially in the mornings.
10. Healthier TeethCoffee and tea stain teeth and acidic & sweet energy drinks or sodas erode tooth enamel and can cause tooth decay.
Eliminating these beverages results in whiter and healthier teeth.
11. Weight LossUnless you drink your coffee black. Caffeinated beverages generally add empty calories to our diets that we don't really need.
Many experts say that sugary beverages are a huge component of the obesity epidemic plaguing the western world.4

Bottled coffees, teas, energy drinks, and sodas often contain an assortment of preservatives designed to give them a longer shelf-life.
These preservatives can have adverse health effects and some are even banned by other countries.
Sugar-free energy drinks and sodas contain artificial sweeteners that also can negatively affect your health.
Cutting these out of your diet can be beneficial to your overall long-term good health.
13. Cleaner EnvironmentCaffeine addiction places a tremendous strain on our natural resources. Think of the number of plastic bottles, cans, and cups that have to be produced in order to meet the demand.
"Americans discard about 33.6 million tons of plastic each year, but only 6.5 percent of it is recycled and 7.7 percent is combusted in waste-to-energy facilities, which create electricity or heat from garbage. The rest ends up in landfills where it may take up to 1,000 years to decompose.." - State of The Planet
Also, caffeine has been showing up in municipal water supplies because of all the discarded coffee grounds.
Quitting caffeine reduces your environmental footprint.
14. Caffeine Will Work AgainConsuming caffeine daily quickly causes the human body to build up tolerance. The same dose of caffeine then causes a person to achieve a sense of normal rather than the euphoric feelings it once did.
Quitting resets your body's caffeine tolerance, allowing it to work really well on the occasions you really need it to.
15. Possible Drug InteractionsCaffeine can interact with other medications causing them to not work as they should.
Giving up caffeine eliminates this risk.

Quitting can give you your steady hands back.
17. Less Risk of Cardiac EventsCaffeine stimulates the heart muscle causing it to beat with more forceful contractions.
While this isn't problematic for most people, those with underlying heart conditions can be at risk. People can be unaware that they even have a heart disorder until they begin to consume caffeine and the damage is done.
18. Increased ProductivityWhat would you do with an extra hour every day?Those addicted to caffeine can easily waste an hour standing in line at the coffee shop, making trips to the break room talking to coworkers along the way, and stopping at convenience stores.
The time saved could be used for an extra hour of sleep instead!
19. Reduced Type 2 Diabetes RiskWhile black coffee actually has been shown to reduce diabetes risk, drinking sugary coffee and caffeinated beverages actually increases your risk of diabetes.
"People who consume sugary drinks regularly-1 to 2 cans a day or more-have a 26% greater risk of developing type 2 diabetes" -Harvard School of Public Health6
20. Better HealthMany research studies point to the health benefits of coffee and tea because of their antioxidant properties. However, this isn't true for all caffeinated beverages.
Soda, energy drinks, and processed coffee and tea products most likely have a negative impact on your long-term health.
People who drink mainly water report more natural energy, better overall feelings of wellness, better sleep, and healthier skin.
Why is caffeine not good for you on your period?
During menstruation the blood volume of a woman decreases and so it is important to not put great oxygen demand on the heart which demands more blood flow. blood demand and blood supply must be insint or balance. The caffeine increase heart rate which put unnecessary pressure on the heart to supply more blood that is not present in the body. this can damage the heart over time.
What products contain caffeine?

Does chocolate liquor contain caffeine?
Yes. During chocolate making, the fibrous husk that surrounds each bean is removed through a process of breaking the bean into pieces, separating the husk from the bean, and then winnowing away the lighter husk from the heavier nibs by use of vacuums or high-pressure fans. The pieces of bean created during winnowing are called cocoa nibs. (The nibs are often ground up before being used to make chocolate, the result being called cocoa mass or cocoa liquor.) It is the nibs that contain the caffeine found in chocolate. The more nibs (or cocoa mass/cocoa liquor) used to make a piece of chocolate, the more caffeine it will contain.
