Avoid Diuretic Drinks and Foods (Caffeine, Alcohol, Tea)

Edited by Debbie, Anonymous, Lynn, Jonathan and 5 others

How much do you know about diuretics? Diuretics encourage your body to excrete urine. The more you consume beverages that are considered diuretics, the more urine you pass. Perhaps the diuretics you are aware of are those that are purchased from your local pharmacy. Physicians often prescribe pharmacological diuretics to help regulate the blood pressure through excretion of urine in hypertensive individuals, and people who retain fluids. However, there are individuals that should not take diuretics, and should also avoid food and drinks that contain dieresis-inducing substances.

Who should avoid diuretic substances?

Before you learn what food and drinks are diuretics, you should know what conditions or illnesses are contraindicated with diuretics.


Individuals who have Anuria (the kidneys fail to produce urine) should not take diuretics. When an individual cannot pass urine, the volume of water inside the body increases as you consume food and drinks. Even if you don't drink anything the entire day, the body still produces urine because of intracellular processes. This refers to the processes and exchanges that happen in the body. As you inhale and exhale, substances and nutrients are exchanged between the cells of your body. As such, waste products like water are excreted as urine or sweat.

When you're dehydrated, the body's reserve of water is used up. As such, the body does not have enough water to use for cellular exchange. If you take in diuretics, or food and drinks that are considered diuretics, you will aggravate the dehydrated condition. Dehydration can become very serious. It's much more difficult for your body to go without liquids, than it is for your body to go without food.

When you have diarrhea, you have continuous bowel movements, even if you don't eat or drink. This is usually a symptom of an underlying condition that requires medical intervention. A person who passes watery bowels three times within 24 hours is said to be experiencing diarrhea. You can measure the frequency of diarrhea in infants by counting the times you must do a serious diaper change. When you have diarrhea, the water and electrolyte balance of your body is affected. You will tend to get thirsty and should drink more water. However, you will also aggravate the effects of the diarrhea if you take diuretic substances.

Gout is a severe type of arthritis, but there are differences between gout and rheumatoid arthritis or osteoarthritis. The pain is severe and usually involves inflammation of your big toe. Gout is caused by the increase of uric acid in your blood. Uric acid is generally harmless and is produced by the body as part of the waste products of cellular exchanges. However, in excess it tends to form calcium crystals. (These can be compared to grains of salt, only microscopic). These calcium crystals travel along with your blood and pass through arteries and veins. Your body naturally excretes uric acid, but if it's not effectively excreted through your urine or feces, it is reabsorbed and circulates again in your body. One problem with gout is that the crystals may wound the passageways they travel along. For instance, when uric acid crystals go through your kidneys, they may get stuck in there and form into a kidney stone. That's why pharmacological diuretics are used with caution in individuals with kidney diseases. When you ingest too many diuretics, there is an excess of water that passes out more easily from the body as urine. When this happens, the circulating uric acid in your blood gets more concentrated, predisposing you to developing a kidney disease through a collection of the crystals in the kidney ducts.
