What is a diuretic?

Decaf Coffee

Diuretic is also called a water pill. It is a medication specially designed to get rid of the body’s excess salt and water through increased urination. Diuretics prompt your kidneys to increase the amount of urine and decrease the body’s fluid and swelling. The excess fluid makes breathing hard and causes complications for the heart to function properly, so diuretics address these conditions. 

Besides medications, some foods and drinks we consume daily also act as natural diuretics such as:

  • Coffee — 95-200 mg caffeine per 8 oz cup
  • Chocolate — 24 mg caffeine per oz
  • Tea — 26 mg caffeine per 8 oz cup
  • Energy drinks — 91 mg caffeine per 8 oz
  • Soda — 49 mg caffeine per 16 oz
  • Chocolate cake with frosting — 8 mg caffeine per slice

They are mild diuretics and their effects depend on overall caffeine consumption from any source. 

Benefits of diuretics

The benefits of diuretics include:

  • Excretion of excess sodium and water.
  • Treatment of high blood pressure.
  • They reduce the risk of cardiovascular, liver, kidney diseases and tissue swelling.
  • Removal of harmful toxins from the body.
  • Help in acne and weight loss.

Side effects of diuretics 

Besides advantages, diuretics also cause the following side effects such as they cause:

  • Dehydration
  • Electrolyte imbalance
  • Headache
  • Dizziness
  • Impotence
  • Muscles cramp
  • Joints disorder

Is regular coffee a diuretic?

Coffee contains sufficient caffeine content so it is a mild diuretic. The caffeine in a regular coffee cup boosts your energy and gives you a short-term diuretic effect. The caffeine moves from your stomach to your bloodstream and liver, developing biochemical and metabolic changes. These changes boost energy and urge your kidneys to produce more urine and eliminate excess water and salt. 

So, it lets you pee more and increase your trips to the bathroom, depending on the amount of your daily coffee consumption. 

Does caffeine make you pee?

Yes, caffeine acts as a diuretic. Normally, your pituitary glands release antidiuretic hormone (ADH) which travels to your kidney, tells it your body is thirsty and needs water, and creates aquaporins. 

Aquaporins transport water to all the cells in your body. So, caffeine inhibits the production of ADH, affects the hydration process, and prevents the absorption of water in the kidney. No ADH, no aquaporins, the water will go to your bladder instead of cells, and make you pee more.

To experience the diuretic effect, you need to consume 360 mg caffeine; however, an 8 oz coffee cup contains only 95-200 mg caffeine. So, ingest two coffee cups to run the diuretic effect on your body. 

Does caffeine dehydrate you?

Caffeine stimulates your metabolism and heats your body. Increase in heat means your body requires more water and you may become dehydrated. So, you can prevent your body from dehydration with the intake of several cups of water. Normally a regular coffee cup causes diuretic effects but does not cause dehydration. Eventually it all depends on your consumption; more caffeine will cause a high diuretic effect and lead you towards dehydration.
