Caffeine

ACTION IN THE BODY AND COMMON SOURCES

Caffeine is a drug used by millions of people daily that stimulates the body. Many people may experience undesirable effects of caffeine stimulation. Caffeine stimulates a person’s “fight or flight” reaction.

Mental activity and feelings of alertness are increased and generally the body is prepared for quick action. These are the primary effects and generally why caffeine is used. However, “What goes up must come down.” The down is the rebound of caffeine consumption that occurs after the dose wears off. This is caffeine’s secondary effect. Symptoms of the secondary effect are why caffeine was consumed the first time. The rebound mental dullness, sleepiness and physical sluggishness may cause a person to desire another dose. This is the cycle of stimulant use. The up and down cycles place excessive stress on the systems of the body and can become addictive.

Some of the adverse primary effects of caffeine stimulation on specific body systems include:

Central nervous system
Stimulation which can cause behavioral changes; insomnia, restlessness, nervousness, anxiety, ringing in the ears, muscular tremor, headaches, lightheadedness.

Cardio-vascular system
Rapid heart rate, irregular heat rate, palpitations, increased or decreased blood pressure, decreased blood flow to the brain, cold hands and feet.

Digestive System
Increased gastric secretion, gastric irritation, ulcers, stomach pain, nausea, vomiting, diarrhea and anal itching.

Immune system
Decreased immune function, decreased thymus gland size, decreased levels of circulating antibodies.

Urinary tract
Kidney and bladder irritation, diuresis, increased frequency of urination, burning during urination.

Secretory glands
Increased sweating, fibrocystic breast changes.

Metabolic
Increased or decreased blood sugar levels, pancreatic cancer, depletion of minerals and water-soluble vitamins and dehydration.

Reproductive
Caffeine is known to cross the placenta and the safety of caffeine exposure before birth is still unknown. Caffeine is passed unchanged through breast milk and is known to contribute to nervous irritability of nursing infants, as well as the above-listed symptoms.

Withdrawal
After discontinuing caffeine consumption, opposite (secondary) effects, as well as headaches, may result for a short while until the body re-equilibrates.
