The Negative Effects of Caffeine to One’s Health


Many of the food we eat contain caffeine. Coffee, tea, chocolate, soft drinks, and both prescription and nonprescription drugs have this substance.

It makes us feel and believe that it can help us stay alert the entire day. However, too much consumption of caffeine-rich food can bring negative health effects, such as the following:


  1. Caffeine raises the level of fatty acids in the blood.
  2. It causes various digestive problems, such as heartburn and GERD.

  4. Caffeine has been shown to possibly cause miscarriage or may slow the growth of a developing fetus when given in doses greater than 300 mg (an amount equal to three cups of coffee) a day. Also, caffeine intake by the mother during pregnancy may affect the heart rhythm of the fetus.
  5. It can also cause ulcer by increasing the secretion of both acid and pepsin in the stomach, which could exacerbate an existing ulcer.

  7. It raises your blood pressure.
  8. It has a diuretic effect that causes increased and frequent urination.
  9. It can cause sleep deprivation, especially if caffeine intake is high and in the evening.
  10. Studies show that caffeine may cause decrease cone density and cause osteoporosis among women.
  11. It may also cause “caffeine nerves” which is characterized by palpitations, shaky hands, and wobbliness of the legs.
  12. It can result to caffeine addiction that causes nervousness, irritability, agitation, headaches or ringing in the ears.
  13. With excessive caffeine intake, your pancreas will have to produce extra insulin to reduce extra blood sugar. Thus, it will require your pancreas to overwork.

Because of this, you should avoid dependence on caffeine at the earliest possible time. Take caffeine at a minimal level, if it cannot be avoided completely.
