Caffeine-Related Health Problems: Top 10

Caffeine-Related Health Problems: Top 10

1. Cardiovascular Problems

Caffeine increases heart rate, elevates blood pressure, and can contribute to the development of heart disease. Both decaf and regular coffee increase cholesterol and homocysteine, the biochemical that science has linked to increased risk for heart attack. Caffeine is also linked to coronary vasospasms. Coronary vasospasms cause 20% of all fatal heart attacks that kill otherwise perfectly healthy people.

2. Stress

Caffeine stimulates the excretion of stress hormones, which can produce increased levels of anxiety, irritability, muscular tension and pain, indigestion, insomnia, and decreased immunity. Increased levels of stress can keep you from making healthy responses to normal daily stress.

3. Emotional Disturbances

Anxiety and irritability are hallmark mood disturbances associated with caffeine consumption, but equally important are depression and attention disorders. Depression may occur as part of the letdown after the stimulant effects of caffeine wear off. It may also appear during the recovery period after quitting caffeine while the brain's chemistry is readjusted. Rather than increasing mental activity, caffeine actually decreases blood flow to the brain by as much as 30%, and negatively effects memory and mental performance.

4. Blood Sugar Swings

Diabetics and hypoglycemics should avoid caffeine. Caffeine stimulates a temporary surge in blood sugar followed by an overproduction of insulin, which causes a blood sugar crash within hours. This rollercoaster causes weight gain since insulin's message to the body is to store excess sugar as fat.

5. Gastrointestinal Problems

Many people experience a burning sensation in their stomach after drinking coffee because coffee increases the secretion of hydrochloric acid, which leads to an increased risk for ulcers. Coffee, including decaf, reduces pressure on the valve between the esophagus and the stomach so that the highly acidic contents of the stomach pass up to the esophagus, which can lead to heartburn and gastro-esophageal reflux disease. No wonder the best selling over-the-counter drugs are the so-called antacids.

6. Nutritional Deficiencies

Caffeine inhibits the absorption of some nutrients in addition to causing the urinary excretion of calcium, magnesium, potassium, iron and trace minerals, and all essential elements necessary for good health.

7. Male Health Problems

Milton Krisiloff, MD, has found that in the majority of cases, men can significantly reduce their risk for urinary and prostate problems by making dietary changes, which include eliminating coffee and caffeine.

8. Female Health Problems

Fibrocystic breast disease, PMS, osteoporosis, infertility problems, miscarriage, low birth weight, and menopausal problems such as hot flashes are all exacerbated by caffeine consumption. Women on birth control pills are particularly at risk since they have a decreased ability to detoxify caffeine.

9. Aging

Many people find that in their forties, they can no longer tolerate the same level of caffeine consumption as they could in their 20’s and 30’s. Production of DHEA, melatonin, and other vital hormones decline with age, but caffeine speeds up that process. Caffeine dehydrates the body and contributes to aging of the skin and kidneys. It has been shown to inhibit DNA repair and slow the ability of the liver to detoxify foreign toxins.

10. Adrenal Exhaustion

Caffeine consumption leads to eventual adrenal exhaustion, which can leave you vulnerable to a variety of health disorders related to inflammation, autoimmunity, and fatigue.
