The 5 Scariest Things Caffeine Does to Your Body

1. Depression
Restricting caffeine and sugar in people with depression has been reported to elevate mood in preliminary research. Caffeine affects our reward centers by influencing the neurotransmitter dopamine. Caffeine increases dopamine levels in the same way as heroin and crack. Its effect is much weaker of course, but the mechanism is the same. Researchers suspect that this dopamine connection is what contributes to caffeine addiction.

2. Gastritis
Gastritis is a broad term for inflammation of the lining of the stomach. This condition can be caused by many factors and, in some cases, may lead to an ulcer. Caffeine found in coffee, black and green tea, some soft drinks, chocolate, cocoa, and many medications increases stomach acid, though decaffeinated coffee does, as well.

3. Infertility
Caffeine consumption equivalent to more than two cups of coffee per day has been linked to fallopian tubal disease and endometriosis, both of which can cause female infertility. As little as one to one and a half cups of coffee per day appears to delay conception in women trying to get pregnant. Some studies have reported that one cup of coffee per day cut fertility in half, although others report that it takes two or three cups to have detrimental effects. While not every study has found that caffeine reduces female fertility, most doctors of natural medicine recommend that women trying to get pregnant avoid caffeine.

4. Osteoporosis
People with osteoporosis have brittle bones, which increases the risk of bone fracture, particularly in the hip, spine, and wrist. Caffeine has been linked to hip fractures in a large study following American women for six years. Caffeine increases urinary loss of calcium. Many nutritionally oriented doctors recommend decreasing caffeine intake from caffeinated coffee, black tea, and cola drinks as a way to improve bone mass.

5. Premenstrual Syndrome (PMS)
Many pre-menopausal women suffer from symptoms of premenstrual syndrome (PMS). Among a group of college students in the United States, consumption of caffeine-containing beverages was associated with increases in both the prevalence and severity of PMS. Moreover, the more caffeine women consumed, the more likely they were to suffer from PMS. Therefore, many nutritionally oriented doctors recommend that women with PMS avoid sources of caffeine.

7 Negative Effects of Coffee

Coffee is world’s favorite drug with us starting most days with a caffeine jolt to get going. Some people enjoy their coffee and apparently have no health issues with drinking it. There are however some potential negative effects of coffee, particularly at certain times and when it becomes so addictive that you find it difficult to go a day without it.

1. Coffee and Hydrochloric Acid
Drinking coffee on an empty stomach is definitely a nono, stimulates hydrochloric acid production. This can be a problem because hydrochloric acid should only be produced to digest meals. If your body has to make hydrochloric acid more often in response to regular cups of coffee, it may have difficulty producing enough to deal with a large meal.

Protein digestion in particular is affected by a lack of hydrochloric acid in the stomach and protein based foods can pass into the small intestine before being properly broken down. Undigested protein is associated in a variety of health problems, from bloating and gas to irritable bowel syndrome, diverticulitis, colon cancer or other health issues.

2. Ulcers, Irritable Bowel Syndrome (IBS)
Many of the compounds in coffee like caffeine and the various acids found in coffee beans can irritate your stomach and the lining of your small intestine.

Ulcers are believed to be caused by the Helicobacter pylori bacteria. However, the acidic effect coffee has on the stomach may contribute to providing the weakened stomach lining necessary for Helicobacter pylori to take hold initially.

Drinking coffee can also irritate the lining of the small intestine, potentially leading to abdominal spasms, cramps and elimination problems, often alternating between constipation and diarrhea (IBS).

3. Heartburn Problems
Acid reflux and heartburn can be caused by coffee due to the way it relaxes the lower esophageal sphincter. This small muscle should remain tightly closed once you’ve eaten to prevent the contents of your stomach from coming back into the esophagus and burning its delicate lining with hydrochloric acid.

This happens when you drink decaffeinated coffee, soft drinks and high caffeine ‘energy drinks’ too.

4. Coffee as a Laxative
Drinking coffee can stimulate peristalsis, the process in the digestive tract that makes us head for the bathroom. Some people use it deliberately as a laxative.

But by stimulating peristalsis, coffee also appears to promote increased gastric emptying, whereby the stomach’s contents are quickly passed into the small intestines, often before the digesting food has been properly broken down. In this partially digested state, it makes it much more difficult for nutrients to be absorbed from your food. It also increases the chances of irritation and inflammation within the gastrointestinal tract.

This also happens when you drink decaffeinated coffee too.

5. Mineral Absorption, Your Kidneys and Coffee
Heavy coffee drinkers may have difficulty getting enough minerals in their diet, even if they eat mineral rich foods or take supplements. This is due to the way coffee affects iron absorption in your stomach and particularly your kidneys ability to retain calcium, zinc, magnesium and other important minerals.

6. Acrylamide in Coffee
Acrylamide is a potentially carcinogenic (cancer-causing) substance that forms when coffee beans are roasted at high temperatures. The darker the roast, the higher the levels of acrylamide are likely to be. In fact, coffee has been shown to be one of the major sources of this dangerous chemical in American diets.

7. Coffee, Stress and Tension
Drinking lots of coffee will promote the release of the stress hormones cortisol, epinephrine and norepinephrine. These chemicals increase your body’s heart rate, blood pressure and tension levels.

Turning on the stress hormones with a cup of coffee when you’re eating also interferes with the digestive process. Your body will divert its resources to being ready for a potential threat and digestion suffers as a result.

Caffeine in coffee is known to interfere with GABA metabolism. Gamma-aminobutyric acid  is a neurotransmitter involved in regulating mood and stress levels.

Conclusion: After many years of coffee intake, I noticed that I’m having frequent stomach problem (IBS?). Even i cut down on my coffee, it’s not improving. Perhaps i should take a more fresher and high-quality coffee, which perhaps could helps.
