Bad Effects of Caffeine on the Body

If you reach for a cup or more of coffee each day, you are not alone. Millions of people enjoy their daily dose of coffee, tea, soda and even chocolate. While caffeine is not harmful in small amounts, larger amounts can cause a host of negative effects. According to the Mayo Clinic, 200 to 300 mg, or about two to four cups of brewed coffee a day, aren't harmful. "But some circumstances may warrant limiting or even ending your caffeine routine."

Dehydration

You might appreciate caffeine as a diuretic, helping you to ward off bloating and extra water weight---however, too much caffeine can cause dehydration. Your body is about two-thirds water, and it's important to keep it that ratio. Dehydration does not allow the normal functioning of your body's processes and can lead to fatigue and skin issues.

Gastrointestinal Issues

Depending on how your body reacts to caffeine, you may endure gastrointestinal issues or upset. Caffeine is a stimulant, and while some people experience diarrhea with caffeine intake, some may also experience constipation due to dehydration. Caffeinated drinks can be particularity acidic, which can cause general stomach upset--and can aggravate ulcers.

Mental Health

Caffeine stimulates the central nervous system and can be a factor or the sole cause of some mental health concerns. It stimulates the adrenal glands to produce more cortisol---also known as the stress hormone---and raises epinephrine levels of the brain. Caffeine can produce irritability, anxiety, panic attacks, depression and sleeplessness. Caffeine coupled with a stressful life and lack of sleep can greatly affect your mental health in a negative way.

Limit Weight Loss

You may believe that caffeine consumption can support weight loss efforts. The truth is that caffeine has negative effects on weight loss. Teeccino.com states, "Coffee and caffeine intake aggravates stress, including physical, mental, and emotional stress, leading to increased levels of the glucocorticoids including cortisol. A well documented relationship exists between chronically elevated levels of these stress hormones and deposition of excess fat in the abdomen leading to obesity."

Estrogen Dominance

John R. Lee, M.D., author of "What Your Doctor May Not Tell You about Menopause," says that caffeine increases the production of estrogen in your body, which can lead to estrogen dominance. Estrogen dominance can be indicative of further complications. Women may experience menstrual issues, loss of libido, fibroids or endometriosis. Men are affected as well and can experience weight gain, male-pattern baldness, loss of libido, prostate issues and gynecomastia--which is breast development in men.
